Lieutenant Commander Steven J. "Steve" McGarrett, USNR (portrayed by Alex O'Loughlin) is the head of the Five-0 Task Force and a former active duty United States Navy officer.

In the pilot, McGarrett was in South Korea on a classified mission escorting wanted arms dealer Anton Hesse when he received a call via satellite phone from his father John and finds out that Anton's brother Victor was coincidentally holding John hostage on an unrelated matter. McGarrett's convoy was attacked by people trying to rescue Anton, resulting in Anton being killed. When Victor finds out, he shoots John point blank with the younger McGarrett still on the line. McGarrett returns to Hawaii to bury his father and is asked by Governor Jameson to set up a task force to investigate and capture criminals such as the Hesse brothers. Despite his initial hesitation, he eventually agrees and transfers to the United States Navy Reserve. He then recruits Newark PD transfer, Detective Sergeant Danny Williams, his father's former trainee Lieutenant Chin Ho Kelly and recent HPD Academy graduate Officer Kono Kalakaua. These four make up the original members of the "Governor's Task Force", later renamed "Five-0".

Since returning to Hawaii, McGarrett has lived in his childhood home at Piikoi Street along the beach, where John McGarrett continued to live in after the break-up of his family and was murdered.^[1] Although technically a haole like Danny, Steve was not only born and raised in Hawaii but respected the local culture and practices and thus accepted as kama'aina.^[2] As such he was not antagonized as much as Danny was by the locals during the first several seasons. Steve was a high school sophomore when his mother Doris was presumed to be killed in a car accident in April 1992,^[3] prompting John to send Steve and his younger sister Mary away to the mainland for their own safety. With the surfacing of crime lord Wo Fat and the theft of John's mysterious tool box, the truth behind Doris' "death" is gradually revealed. Steve is said to be fifteen or sixteen in 1992, putting his birth year in 1976 or 1977, which roughly corresponds with the fact that he was in BUD/S in the year 2000.^[4]

McGarrett is a third-generation Navy veteran and was named after his late grandfather, Ensign Steven McGarrett, who perished on the USS Arizona during the attacks on Pearl Harbor in December 1941. His grandfather has been referenced a number of times as the younger McGarrett had met a Japanese American internee^[5] and a retired Petty Officer^[6], both of whom knew Ensign McGarrett when he was still alive. A star quarterback, Steve attended fictional Kukui High School before being sent to the Army and Navy Academy in California for his junior and senior years after the death of his mother. He graduated from the United States Naval Academy and went on to have a distinguished career. Governor Jameson once outlined his résumé "Annapolis, five years Naval Intelligence, six years with the SEALs. Your superiors say that you are the best they have ever seen."^[7] McGarrett graduated from BUD/S Class 203 (in real life, Class 203 graduated in 1996, not the 2000s).^[6] His time in the military is largely unknown or vague due to the highly classified nature of most of his missions, but it was mentioned that he served in Afghanistan^[8] and North Korea, was stationed at Coronado at some point in his career^[9] and was known by the nickname "Smooth Dog".^[8] He is conversant in Asian languages; he speaks Mandarin fluently and knows conversational Korean and Japanese. He is friends with former Navy SEAL Senior Chief Petty Officer, now NCIS Special Agent Sam Hanna from NCIS: Los Angeles. Prior to his father's murder, he served on a "black op" with his best friend, Freddie Hart, but the mission went south and Hart was killed; his body was not recovered until Season 3 when McGarrett personally flew to North Korea to oversee the repatriation.^[4] In season 4, he admits to Lou Grover that after Hart's death, the Navy "didn't feel the same" anymore and that he jumped at the chance to leave when Governor Jameson asked him to set up the task force.

Despite the fact that he is longer on full-time active duty, McGarrett's military background and SEAL training are still evident in his daily routine and habits; he still takes a "Navy shower", keeps his house impeccably neat and tidy, maintains a fitness regimen and is extremely sensitive to sound even when asleep. His military mannerisms are also apparent in the way he approaches his cases and his ability to remain calm even when under intense pressure and is frequently mocked by Danny for his lack of "human" touch, although in later seasons he would be seen cracking jokes with other team members.^[10] Despite his stoicism, he has a soft spot for children, especially Danny's daughter Grace, who calls him "Uncle Steve", and is extremely protective of his younger sister Mary, once even physically threatening a suspect who was involved using Mary as a mule.^[11]

McGarrett uses the same weapons he used as a SEAL including a SIG P226R as his sidearm as well as MP5K and Heckler & Koch MP7 submachine guns, and HK416 rifles.

Much of McGarrett's interaction with Danny outside of work usually begins and ends with the duo bickering over trivial matters or good-naturedly mocking one another; there is a running gag in the show where various characters would comment on how the duo bicker like an "old married couple". Although they seem like polar opposites - for example, McGarrett keeps his house neat and tidy and keeps his emotions bottled up while Danny is shown to be a slob^[12] and often vocalizes his frustrations by ranting - they form an unlikely friendship, with McGarrett mocking Danny in his deadpan humor several times about how the latter misses him secretly but refuses to admit it. Although he is often referred to as "Boss" by the other members of Five-0 and he is usually seen giving orders, he considers the other members of the team as his peers and ohana (family), as mentioned in the Season 5 premiere.

McGarrett is an extremely private man who rarely shares aspects of his personal life or preferences, in contrast to Danny, who rants about anything and everything he dislikes. Despite Danny's persistent prying, he never speaks of his military service, largely because of the classified nature of most of his missions, often brushing Danny off with "it's classified". He frequently displays little or no emotion in situations where Danny is extremely emotional. It is not until Season 5 that McGarrett finally explains to Danny that he was raised in a family environment where males were not encouraged to express emotion.^[13]

One of McGarrett's hobbies is antique cars, in particular, his father's 1974 Mercury Marquis. As a boy, he would watch his father fix the Marquis in the garage. The Marquis used in this series is the same car that Jack Lord, who portrayed McGarrett, drove in the original series.^[14][1]

Danny Williams

Danny Williams
First appearance	Pilot (episode 1.01)
Portrayed by	Scott Caan
Other appearances	NCIS: Los Angeles
Information
Full name	Daniel Williams
Nickname(s)	Danno (by Grace and Steve) Jersey (by Kamekona) Haole (by Kamekona)
Occupation	Member of the Five-0 Task Force Detective, Honolulu PD (formerly) Police officer/detective, Newark PD (formerly)
Title	Detective Sergeant
Family	Eddie Williams (father) Clara Williams (mother) Matthew Williams (brother; deceased) Stella Williams Russo (sister) Unnamed sister
Spouse(s)	Rachel (ex-wife)
Significant other(s)	Gabrielle Asano (ex-girlfriend) Amber Vitale (a.k.a. Melissa Armstrong)
Children	Grace Williams (daughter) Charles Edwards (son)
Relatives	Eric Russo(nephew)

Detective Sergeant Danny Williams (portrayed by Scott Caan) is a member of the Five-0 Task Force and the de facto second in command. He is an experienced detective whose police background and tendency to go "by the book" clashes with McGarrett's "shoot now, talk later" style.

It is established in Season 1 that Danny was from New Jersey, presumably around the New York metropolitan area, and was only living in Hawaii because his ex-wife Rachel had remarried and moved there with their daughter Grace to join her new husband Stan Edwards. He transferred from Newark PD to the Honolulu PD to be closer to Grace. In the Pilot, Danny had been living in Hawaii as a cop for six months when he was assigned the murder investigation of John McGarrett.

This brought him into contact and conflict with John's son, Lieutenant Commander Steve McGarrett who sought to personally investigate the crime himself and as such, this led to bad blood between the two and Steve used his influence to become the leader of the unnamed Task Force. Despite Danny's misgivings, Steve appointed Danny as the second-in-command of the team and also made Danny his partner in the field. Unfortunately, things eventually came to a head in the aftermath of a shooting where Danny threatened Steve, Steve responded by placing Danny in an armlock before forcing Danny to apologize. Danny, on the other hand upon being let go punched Steve and remarked, "You're right. I don't like you" before leaving while Steve was left reeling and obviously stunned that he had underestimated Danny. However, the team later grew to accept and value Danny's skills as seen during "Malama Ka Aina/Respect The Land" where Danny gave them information about a crime boss he had presumably encountered or heard of during his days as a cop in New Jersey.

In "Ua Hiki Mai Kapalena Pau/Until the End Is Near", Danny fell ill after touching the body of a man to check for a pulse. This incapacitated him for a time and he suffered convulsions, forcing him to be taken to hospital for treatment. Agent Jenna Kaye later realized that Danny had been infected with sarin. As such, with Danny in hospital, the team turned their attention to finding out who had poisoned the victim and Danny. Danny eventually made a full recovery and it was later revealed that he was having an affair with Rachel in the season 1 finale, although they later broke it off for good with Rachel returning to her husband, Stan Edwards. Danny was left without a job after Five-0 was disbanded due to Steve being arrested for the murder of Governor Jameson.

In the season 2 premiere, Danny teamed up with Steve's former CO Joe White and Chin to help clear Steve's name. Though they succeed, Danny found footage of Steve's father meeting with Wo Fat and Governor Jameson with no audio. In "Ha'alele/Abandoned", when Steve headed to Japan to find Joe White and seek answers in regards to "Shelburne", Danny took temporary control of the team as they investigated a serial killing case. In "Pa Make Loa/Touch of Death", a crossover with NCIS: Los Angeles, Danny and Five-0 teamed with agents G. Callen (Chris O'Donnell) and Sam Hanna (LL Cool J) from the NCIS Office of Special Projects to stop a smallpox virus.

Danny often rants to McGarrett about his dislike for everything Hawaiian, from pineapples on pizza to surfing etiquette, while McGarrett would mock his affinity for wearing ties and loafers at work, a practice not common in Hawaii. Regarded as a haole for wearing a tie on the island during the first season, Danny is often viewed as a curiosity or with disdain by the locals and other HPD cops^[15] and the first season sees the rest of the team often having to explain to him the idiosyncrasies of life in Hawaii. For example, his insistence on wearing a tie and loafers to work^[16] and disregard for surf etiquette or Native Hawaiian culture is met with ridicule and light-hearted derision from his co-workers. He gradually comes to accept Hawaii as his home and stopped wearing ties.

The son of Eddie and Clara Williams, he comes from a large working-class family and is the oldest of four children. He has a younger brother Matt and two sisters (one of whom is named Stella), both of whom are married. He began his career as a police officer with the Newark PD; as a patrol officer, Danny testified against his training officer, Rick Peterson (Peter Greene), under a subpoena during Peterson's trial for corruption.^[17] In 2001, he witnessed the murder of his partner Grace Tilwell by a pair of gangsters they had been sent to apprehend. After barely making it out alive, he notices smoke billowing from the World Trade Center and was later ordered to New York City to assist the NYPD. That day still haunts Danny and his daughter Grace was named after Tilwell.^[18] Danny is portrayed as a loyal cop who is married to his job first and life second. As a consequence, he is often at odds with his ex-wife Rachel for sometimes not being on time. He is very loyal to his friends and colleagues, once refusing to believe that his former HPD partner Meka was corrupt even when pitted against overwhelming evidence after the partner was found dead (season 1, episode 8). Likewise, he often gives Steve the benefit of the doubt even when the latter resorts to more "unorthodox" methods in the investigation as he trusted Steve's judgment.

A running gag in the show is the regular "carguments" between Danny and McGarrett.^[19] Much of Danny's interaction with McGarrett outside work usually involves an argument on the way to and from a crime scene or when interviewing suspects, resulting in characters commenting about the duo being like an "old married couple".^[20][21] Indeed, his "by-the-book" style contrasts with McGarrett's "the ends justify the means" approach (which Danny calls "shoot now, ask questions later"), and is a source of friction (and banter) between the two. Lou Grover once described Danny as "the brains" to McGarrett's "brawn".^[22]

In "Hana Keaka", it is mentioned that Danny attended Seton Hall University where he minored in business, which made him the ideal candidate to go undercover at Oahu State University as an economics professor.^[23]

Danny's pistol is an H&K P30 although he carried a SIG Sauer SP2009 in the pilot.

He is a passionate football fan and has mentioned that he is a fan of the New York Jets and Super Bowl-winning quarterback Peyton Manning.^[24]

Chin Ho Kelly

Chin Ho Kelly
First appearance	Pilot (episode 1.01)
Portrayed by	Daniel Dae Kim
Other appearances	NCIS: Los Angeles
Information
Nickname(s)	Chin
Occupation	Member of the Five-0 Task Force Police officer/Detective, Honolulu PD (formerly)
Title	Detective Lieutenant
Family	Kam Tong Kelly (father, deceased)
Spouse(s)	Malia Waincroft (deceased)
Relatives	Keako (uncle) Mele (aunt) Kono Kalakaua (cousin) Gabriel Waincroft (brother-in-law)

Lieutenant Chin Ho Kelly (portrayed by Daniel Dae Kim) is the third member of Five-0. He was a former Honolulu Police Department police officer who left the force due to false allegations of corruption. He is close friends with the McGarrett family as his late father Kam Tong was a long-time colleague of John in the HPD while Chin was trained by John during his rookie days patrolling the beat.^[25] In the pilot episode he was recruited by Steve for the new task force and often serves as the team's technical expert and designated sniper alongside his cousin Kono. Throughout the show, he is often seen manipulating the smart board in the office or fiddling with all things digital.

Chin attended Kukui High School and was the star quarterback until McGarrett broke his records as a sophomore. After that season, McGarrett was sent off to a military school on the mainland. As a high school student, Chin was described as being multi-talented with a wide variety of interests, having played football and was also in the math club and school band.^[26] He then joined the HPD, rising to the rank of Detective before leaving over false allegations that he had stolen money from the evidence locker. It is eventually revealed that it was his uncle, a retired cop himself, who had done it out of desperation over the expenses for his cancer-stricken wife's treatments. Kono confronts Chin about it but he flatly refused to turn his uncle in for fear that it would cause all the cases his uncle had solved to be reopened and the criminals would be released. After it became known that the allegations against Chin were false, he was reinstated to the Honolulu Police Department with the rank of Lieutenant.

In the season 2 finale cliffhanger, Chin is put in a difficult position after a group of corrupt ex-HPD cops simultaneously hold Kono hostage and threaten Malia in the couple's own house as part of a plot to free Frank Delano from Halawa. He chose to save his wife but Delano still orders his men to kill both women. Kono, bound and gagged, was pushed into the sea but was rescued by Adam, who was hiding nearby. The paramedics were unable to save Malia and she dies at home.

It is revealed in Season 4 that Chin's father was murdered fifteen years ago by his brother-in-law Gabriel Waincroft, who grew up to become a notorious drug lord despite Chin's efforts to set him straight. At that time, Chin and Malia, then rookies in their respective occupations, were dating and Malia had asked Chin to talk to her wayward younger brother, then a known juvenile delinquent. Kam Tong happened to be at the wrong place at the wrong time when Gabriel was ordered to kill someone as part of his gang initiation. Years later, at Kono and Adam's wedding, Gabriel confronts Chin and tells him that while he was sorry that Kam Tong was the unfortunate victim of his gang initiation, he blamed Chin for failing to protect Malia.

Unlike the other Five-0 members, Chin often rides a motorcycle to work. It has been said that "everyone" knew who Chin was and his intimate knowledge of the island of Oahu and Hawaiian culture, rapport with the locals and ability to speak Hawaiian often aids the team when dealing with locals who are often suspicious of haole cops (such as Danny). His "street smarts" and local knowledge complements Danny's experience as a detective, McGarrett's

Chin's pistol of choice is the SIG-Sauer P229R. He previously used the HPD standard-issue Smith & Wesson Model 5906.

Kono Kalakaua

Kono Kalakaua
First appearance	Pilot (episode 1.01)
Portrayed by	Grace Park
Information
Full name	Kono Kalakaua
Occupation	Member of the Five-0 Task Force Professional surfer (formerly)
Title	Officer
Family	Ke'ano Kalakaua (father) Nani Kalakaua (mother)
Spouse(s)	Adam Noshimuri
Relatives	Keako (uncle) Mele (aunt) Chin Ho Kelly (cousin)

Officer Kono Noshimuri (née Kalakaua) (portrayed by Grace Park) is a fresh HPD academy graduate who was recruited by Steve for the new task force in the pilot episode. She is the cousin of Chin Ho Kelly. Despite her slight frame, she is well-versed in martial arts and is a skilled marksman (she is usually the designated sniper when the situation requires one).

Kono was a former professional surfer but a serious injury to her knee ended her career. She decides to join the "family trade" and was days away from graduating from the HPD academy when McGarrett recruits her for the new "Governor's Task Force", as Five-0 was initially called. In the first several episodes of season 1, she works under the watchful eye of her cousin and quickly wins the trust and confidence of the other team members. She is detained and questioned by the HPD, having been accused of stealing $10 million from an HPD asset forfeiture locker. While on suspension, she helps Chin and Danny go after Wo Fat, who was responsible for framing McGarrett for the murder of the Governor. To the members of the Five-0 task force and to the general public, Kono had been stripped of her badge by the Internal Affairs Department of the HPD, but it was later revealed to be a ploy for her to go undercover to bust a string of dirty ex-cops.

In Season 2, Kono began a relationship with Hiro Noshimuri's son, Adam. When Adam's brother, Michael, is released from prison, he kills someone with Kono's gun to frame her. She is cleared, but Adam has to kill Michael to protect her and Kono goes into hiding with Adam, skipping from one place to another to evade capture by vengeful yakuza members. At the beginning of Season 5, Adam starts to talk about marriage, and in the episode "Blackout" Kono accepts his proposal. They marry at the end of the season, but in the Season 6 pilot they are tortured by Chin's brother-in-law, Gabriel, who runs away with Adam's money.

Catherine Rollins

Catherine Rollins
First appearance	"Lanakila" / "Victory" (episode 1.04)
Last appearance	"Ua 'o'oloku ke anu i na mauna" / "The Chilling Storm is on the Mountains" (episode 6.03)
Portrayed by	Michelle Borth
Information
Full name	Catherine Rollins
Nickname(s)	Cath
Occupation	Member of the Five-0 Task Force (inactive) Private investigator (formerly) United States Navy officer (formerly)
Title	Lieutenant
Family	Unnamed parents
Significant other(s)	Steve McGarrett Billy Harrington (ex-boyfriend; deceased)

Lieutenant Catherine "Cath" Rollins, USN (Ret.) (portrayed by Michelle Borth) is the on-off lover of Steve McGarrett. How or when they met is never fully explained but it has been implied that they have known each for a long time. It is likely they would have had to keep their relationship a secret due to strict fraternization rules in the U.S. military and the fact that McGarrett outranked her.

Cath is a "Navy brat" and moved around frequently due to her father's various assignments.^[9] During Pro Bowl weekend, when asked why she supported the Dallas Cowboys, she explained that had never stayed in any one place long enough to feel an affinity for an NFL team.^[24] She herself joined the Navy and is an Intelligence Officer. Like McGarrett, her military service record remains vague. She previously dated Billy Harrington, one of McGarrett's SEAL buddies whom she had worked with.

Cath is first introduced in the Season 1 episode "Lanakila", when McGarrett calls her for "a favor".^[21] Later in the season, she stays with him while on leave, resulting in Danny commenting on how McGarrett had "that stupid smile" despite being called in on a Saturday to work a murder-abduction case.^[9]

In the season 4 episode "Makani ʻolu a holo malie/Fair Winds and Following Seas", Cath persuades McGarrett to go with her to Afghanistan to find a young boy named Najib. Najib's father had saved her when she was injured and separated from her unit while deployed to Kabul. McGarrett was captured by Taliban insurgents and is nearly beheaded but a team of Navy SEALs rescue him in the nick of time. As a result, he escapes a court-martial and returns stateside with a stern warning that "these rogue ops of yours are over". Cath decides to remain in Afghanistan to continue her search for Najib and bids a tearful goodbye to McGarrett over the satellite phone. It was implied that McGarrett never really moved on as he never indicated any interest in any of the women Danny or Ellie Clayton attempted set him up with.

Cath makes a surprise return in the season 5 finale for Kono and Adam's wedding. Steve welcomes her with a hug when she surprises him at his backyard. The writers have stated that their relationship will be addressed during the first several episodes of season 6.^[27] She leaves once again after turning down Steve's marriage proposal saying that she had something to do. A heartbroken Steve tells her that he could not wait for her any longer if she decides to leave again and she departs in tears. However, she makes a call to an unidentified person stating that Steve believed her story and that she was "ready". In the episode "Hoa 'inea" / "Misery Loves Company", it is revealed that Steve had deleted her number from his phone, suggesting that he was ready to let her go.

Michelle Borth was originally a recurring guest star up until the Season 3 premiere, "La O Na Makuahine" where she was added to the opening, resulting in her becoming a series regular. The season 4 episode "Makani ʻolu a holo malie/Fair Winds and Following Seas" was the last to credit Borth as a main cast member. In her last appearance, she was credit as a guest star.

Dr. Max Bergman

Max Bergman
First appearance	"Nalowale" / "Forgotten/Missing" (episode 1.05)
Portrayed by	Masi Oka
Information
Occupation	Chief Medical Examiner
Title	Doctor
Family	Mr. & Mrs. Bergman (adoptive parents)
Significant other(s)	Sabrina

Dr. Max Bergman (portrayed by Masi Oka) is the Chief Medical Examiner. Bergman was initially billed as a recurring character but Oka joined as a series regular and has been part of the main cast since Season 2.^[28]

Dr. Bergman was first introduced to Five-0 by Governor Jameson. He was playing the piano and then wordlessly proceeded to explain the victim's cause of death to Danny and McGarrett, before finally greeting them and introducing himself. He has the tendency to rattle off trivia, prompting the Five-0 team to cut him off and tell him to get to the point. Danny often mocks him with medical jokes. Despite his lack of social skills, he does get along with the other members of Five-0. He has a Halloween tradition of dressing up as a character from a Keanu Reeves film.

In the season 2 episode "Haʻalele", it is revealed that his biological mother was murdered by the notorious "Trashman", a serial killer in Hawaii in the 1980s who earned the nickname because his victims were all found in trash bags or the dumpster. He was born to a Japanese-American mother but adopted by a Jewish^[29] family, the Bergmans, after a short stint in foster care, hence his last name. As an undergraduate at Arizona State University, he was a self-confessed party boy and earned the nickname "Beerman".^[30]

Lou Grover

Lou Grover
First appearance	"Aloha Ke Kahi I Ke Kahi" / "We Need Each Another" (episode 4.01)
Portrayed by	Chi McBride
Information
Full name	Louis Purnell Grover[10]
Occupation	Member of Five-O Task Force Head of SWAT, HPD (formerly) Head of SWAT/police officer, CPD (formerly)
Title	Captain
Spouse(s)	Renée Grover
Children	Will Grover[31] (son) Samantha Grover (daughter)

Captain Lou Grover (Portrayed by Chi McBride) is the former head of the Honolulu Police Department SWAT Team. He was often at loggerheads with McGarrett over what he felt was Five-0's tendency to be trigger-happy with armed suspects. When he leaves HPD and is recruited by McGarrett to Five-0, Danny viewed him with suspicion due to his past with Five-0. By the latter half of Season 4, he is fully accepted into the Five-0 ohana. The character was named after a Captain Grover (Scott Brady) from the original series.^[1]

Grover initially disliked McGarrett because of the latter's refusal to disobey orders to "wait for SWAT". He lodges a complaint with Governor Denning, who dismisses Grover's complaint and then promptly orders the duo on an assignment to serve a warrant for a computer hacker. His past is revealed in "Pale 'la" ("Buried Secrets") where he blames himself for having failed to save a boy who was taken hostage by his father, which ultimately resulted in a murder-suicide. In the season 4 finale, Grover's actions to rescue his daughter result in forced early retirement from HPD, but also allows McGarrett to recruit him to be part of the Five-0 team, which he accepts.

He and his wife Renée (portrayed by Michelle Hurd) have two adolescent children: daughter Samantha (portrayed by Paige Hurd) and son Will (has yet to appear on the show but mentioned multiple times). He is shown to be a doting father who is fair but firm with his children. As Danny also has a daughter, Grover sometimes gives him tips and unsolicited advice on dealing with preteens.^[32]

Grover has an ongoing good-natured rivalry with McGarrett. McGarrett would light-heartedly joke about Grover being a "city boy" out of his element on a tropical island^[33] while Grover would poke fun about McGarrett getting himself into trouble because of his refusal to ask for help.

Grover's weapon of choice is the Kimber Custom TLE II.

Jerry Ortega

Jerry Ortega (Portrayed by Jorge Garcia) is a conspiracy theorist who lives in his mother's basement (until she moves to Maui) who regularly assists the Five-0 Task Force with various cases. He was first introduced in the episode "Ka 'oia'i'o ma loko / The Truth Within". Jerry was classmates with Chin Ho Kelly at Kukui High and they were in the school band. A running gag in the show is the fact that he is either resistant or reluctant to use cellular technology to communicate with McGarrett (e.g. he once used a rotary phone to directly call McGarrett about updates for a case) and tends to ramble about conspiracies over everything. The Five-0 team largely tolerate and humor him as he often helps them with cases involving hackers or the internet underbelly. After much pestering, in season 5, McGarrett finally lets Jerry have his own "office" – an empty file storage room in the basement – and officially hires him as a "consultant".

Jerry is a fan of Elvis Presley, which was discovered when Five-0 was called to investigate a murder of an Elvis impersonator in the episode "Ua heleleʻi ka hoku / Fallen Star". In the same episode he shows off his musical talent by singing at the open mic when hanging out with the team for drinks after the case.

Lori Weston

Lori Weston
First appearance	"Ua Lawe Wale" / "Taken" (episode 2.02)
Last appearance	"I Helu Pu" / "The Reckoning" (episode 2.16)
Portrayed by	Lauren German
Information
Occupation	Special Agent, DHS Special Agent/Profiler, FBI (formerly)
Title	Special Agent

Special Agent Lori Weston (portrayed by Lauren German) is a former DHS agent with a background as a profiler. She is viewed with suspicion by McGarrett and his team. Danny would disparagingly refer to her profiling skills and the fact that she was hired by Governor Denning to "babysit" them. Her background in martial arts proves to be an asset as she is able to take down suspects and quickly proves her worth. She returns to the DHS at Governor Denning's request when Five-O get tangled in an incident with an employee of the Russian consulate.

As Catherine Rollins was deployed, she spends a lot of time with McGarrett, but the latter regards her a good friend rather than a romantic interest. She had developed a crush on him but realizes that McGarrett has always been in love with Catherine. Before her departure, she hands him the UH season tickets she had bought.

Recurring

Family members

Mary Ann McGarrett

Portrayed by Taryn Manning

Mary Ann McGarrett is the younger sister of Steve McGarrett. She, along with her brother, were both sent to the mainland after their mother was (presumably) murdered. Steve went to the Army and Navy Academy in Carlsbad, California while she lived with their Aunt Deb several hours away. As a result, both siblings had harbored resentment over their father splitting up the family and drifted apart over the years; in the episode "Lanakila", she comments to her brother that the last time they met in person was at their mom's funeral over fifteen years ago. She is the "black sheep" of the family, wandering from job to job, and was said to be living in Los Angeles when Steve returns to Hawaii for good. She takes a job as a flight attendant but quit after her "friend" Angela had betrayed her and took advantage of her naivete to be a mule for trafficking blood diamonds.

In season 4, Mary adopts a baby girl and names her Joan, after her father. Steve was initially against it but he comes to accept Joan after being forced to babysit her for the day. Since then, Mary and Steve have reconnected and she regularly sends him videos of Joan.

John McGarrett

Portrayed by William Sadler

Sergeant John McGarrett, HPD (Ret.) (1942-2010) is the father of Steve and Mary Ann McGarrett and (presumed) widower of Doris McGarrett. His own father, Ensign Steve McGarrett, was killed in action on the U.S.S. Arizona (BB-39) during the attack on Pearl Harbor and John was born three months later on March 15. John would follow in his father's footsteps into the Navy, serving in the Vietnam War and reaching the rank of Lieutenant before becoming a Honolulu Police Department detective. After Doris' presumed death, he launched his own investigation and sent Steve, then a high school junior, to board at the Army and Navy Academy in Carlsbad, California and Mary to live with his older sister Deb, who lived several hours away from Steve's new school, for their safety. It is presumed that this was the last time the siblings ever saw him in person as they became estranged from their father for sending them away; Steve only learns the real reason why his father split up the family when he returns to Hawaii to head the new task force following John's murder. In light of the revelation, they were able to let go of their animosity and are often seen visiting his grave site.

John has been mentioned a number of times as Steve regularly works with HPD officers, many of whom were John's former colleagues. Even renowned diamond smuggler and fence August March (Ed Asner) paid tribute to John's sense of integrity by telling Steve about how John turned down his $100,000 bribe over three decades ago.^[11]

John McGarrett was murdered by Victor Hesse on September 20, 2010, as witnessed by Steve, who was overseas on a highly classified mission in South Korea, via satellite phone. He was buried at the National Cemetery of the Pacific with full military honors.

Doris McGarrett

Portrayed by Christine Lahti

Doris McGarrett is the wife of the late John McGarrett and mother of Steve and Mary Ann McGarrett. She was presumably murdered by a car bomb when Steve was aged fifteen or sixteen. It is revealed in Season 3 that she was a former CIA operative who went by the alias "Shelburne" and had faked her own death as a cover to escape underground in order to protect her family.

In the Season 3 premiere, Joe White brings Steve to Suruga Bay in Japan where mother and son are reunited. Steve was hostile to his mother, even refusing to call her "Mom", due to the years of resentment over how the family was torn apart by her supposed death and watching his father grieve over her. Mary also initially refused to see her after learning the truth from Steve. For the rest of the season she constantly refuses to tell everything to Steve and he does not fully trust her. He sends Cath to "babysit" her at his house but Wo Fat bypasses Steve's security system and Cath into the house to confront Doris. Despite being a crack shot and armed, ballistic evidence showed that she had intentionally shot away from him, which she attributed to her nerves and shock over Wo Fat's sudden appearance, but Steve refuses to believe her story. Over the next two seasons, bits and pieces (and rumors) of Doris' connection to Wo Fat are revealed. Steve only learns the full truth after he was abducted and tortured by Wo Fat in the 100th episode.

Aunt Deb

Portrayed by Carol Burnett

Debra "Deb" McGarrett is older sister of John McGarrett and aunt of Steve and Mary Ann McGarrett. She raised Mary when John had sent the kids away from Hawaii for their safety after Doris was presumed to be murdered by a car bomb. Steve and Mary both see her as a maternal figure and she, having never married or had children, treats them as her own. Deb had been a struggling singer on the cusp of a big break when she left a promising career to raise Mary. In season 4, she pays Steve a surprise visit for Thanksgiving and reveals that she had stage four cancer. In season 5, she agrees to go for chemotherapy and her brain tumor has shrunk. She marries Leonard Cassano (Frankie Valli), a retired defense lawyer with stage four leukemia whom met during chemo. In the episode "Ua Ola Loko I Ke Aloha / Love Gives Life Within" she returns to Hawaii with Leonard's ashes and passes away in Steve and Mary's childhood home (which Steve has lived in since his father's death) after fulfilling all but one thing on her bucket list - climb a tall mountain. Steve and Mary complete her list by scattering her ashes on the mountain top.

Grace Williams

Portrayed by Teilor Grubbs

Grace Williams is the daughter of Danny Williams and Rachel Edwards. Her parents divorced in the timeline before the pilot and she moved to Hawaii with her mother and millionaire new stepfather. She attends the Academy of the Sacred Heart, a fictional private school, and participates in the cheerleading team. She calls her father "Danno" and is the only person he unconditionally allows to call him that; McGarrett would mock Danny using the nickname or with the tagline "Book 'em, Danno", much to Danny's exasperation. Grace is named after a former partner of her father's (also called Grace) who was killed in the line of duty by a criminal that both were chasing while both were in the Newark PD.

Grace is well-liked by the rest of the Five-0 ohana. She took to "Uncle Steve", as she calls McGarrett, who affectionately calls her "Gracie". Whenever Danny was unavailable due to extenuating circumstances, McGarrett would be the one to pick her up from school or personally reassure her.

Grace was often the source of Danny's disputes with his ex-wife over his visitation rights. Rachel would use their daughter as leverage and make empty threats about rescinding or lessening his visitation days. Eventually, Danny takes the matter to court and is awarded joint custody, meaning that Grace cannot move away from Hawaii without Danny's approval.

Rachel Edwards

Portrayed by Claire van der Boom

Danny's ex-wife and mother of Grace. She moves to Hawaii after marrying millionaire Stan Edwards. Early in Season 1, she and Danny are often seen bitterly arguing on the phone to the point where the whole team knew about the feud even before they had met Rachel or Grace in person. She often used Grace as leverage and threatened to further limit his visitation rights when his job prevented him from being punctual to their father-daughter dates but Danny successfully files for joint custody, meaning that Grace cannot leave Hawaii without his consent. They are on friendly terms, particularly after her marriage with Stan hits a rocky patch and Danny was there to help with Charlie's birth (which he later discovers was actually his, not Stan's).

Malia Waincroft

Portrayed by Reiko Aylesworth

Chin's wife, Dr. Malia Waincroft was previously engaged to Chin before he broke up with her after losing his badge. The two reconnected after he joined Five-0, and then resumed their relationship. She marries Kelly in the episode "Alaheo Pauʻole", but dies in "La O Na Makuahine", the third season premiere episode, from injuries sustained after she was shot, leaving Chin devastated. She had a brother named Gabriel Waincroft who was revealed to be responsible for the murder of Chin's father 15 years earlier.

Adam Noshimuri

Portrayed by Ian Anthony Dale

Kono's husband who becomes a new head of the Japanese Yakuza after Wo Fat murders his father, Hiro. He has been trying to legitimize and clean up his organization with the intention of distancing himself from his father's criminal past. After killing his brother, Michael, to protect Kono, he and Kono leave Hawaii and go into hiding. He comes out of hiding after his brother's loyalists are no longer a threat. At the beginning of Season 5, Adam proposes to Kono and at the end of this season they marry. In "Mai ho`oni i ka wai lana mālie", Adam is shot by Gabriel Waincroft, who runs away with the money that Adam would use to distances himself from the Yakuza.

Almost immediately after Adam killed two Yakuza thugs in "Piko Pau 'iole" to save himself and Kono, Gabriel buys off Adam's debt in order for his cartel to team up with the head of the Hawaiian Yakuza. He subsequently turns himself in to the Honolulu Police Department. After a short legal battle he is sentenced to 18 months in prison.

Other

Kamekona Tupuola

Portrayed by Taylor Wily

Kamekona Tupuola is the owner of Waiola Shave Ice, Kamekona's Shrimp Truck and Kamekona's Helicopter Tours. He did some time in prison and started his shave ice stand while getting back on his feet after being released. He is a confidential informant who uses his former ties in the criminal underworld to get Five-0 important information. In the season 5 finale, he mentioned that his shrimp truck business is now in doubt, after Steve and Danny dropped a nuke into the sea to prevent it from blowing up on land. Members of the Five-0 Task Force and their families are often seen patronizing his shrimp truck or asking him for favors (e.g. he babysat Grace Williams, Danny's daughter, and chaperoned Steve's sister Mary while they were at work). His late cousin, Thomas Hoapili, was a master of Kapu Kuʻialua, an ancient Hawaiian martial art, as is Thomas's daughter, Maggie (portrayed by Summer Glau).

Governor Pat Jameson

Portrayed by Jean Smart

Pat Jameson was the Governor of Hawaii in Season 1. When Steve McGarrett returns home to Hawaii to bury his father, who was murdered by arms dealer Victor Hesse, she requests him to set up a task force with "full immunity and means" to apprehend criminals such as Hesse. McGarrett flatly turns her down as he felt she only asked him to do so for political reasons and boost her ratings. Once he realizes he had no jurisdiction over the investigation, he quickly accepts the job and sets the "Governor's Task Force", which came to be called "Five-0".

In the Season 1 finale, it is revealed that Governor Jameson was actually colluding with Wo Fat. McGarrett confronts her about it in her office but is tasered by Wo Fat, who then shoots and kills the Governor and puts the gun in McGarrett's hand to frame him.

Duke Lukela

Portrayed by Dennis Chun

An HPD Sergeant who often acts as a liaison to Five-0. He was one of the few HPD cops who was not antagonistic towards Danny or the other Five-0 members from the beginning, as he was colleagues with Steve's father and also personally knew Chin and Kono's family. In "Hookman", he was shot by Curt Stoner (Peter Weller), but survived and recovered.

Chun is the son of Kam Fong Chun, who played Chin Ho Kelly on the original Hawaii Five-O.^[1]

Joe White

Portrayed by Terry O'Quinn

White is Steve McGarrett's former SEAL trainer and a long-time friend of John McGarrett and mentor to Steve. He is a "mustang", having been a Master Chief Petty Officer before gaining a commission and retiring as a Lieutenant Commander. In the season 2 episode "Kiʻilua", he is forced to retire after leading an unsanctioned mission to rescue McGarrett in North Korea.

White was one of the few people who knew about Shelburne but he refused to disclose it to McGarrett as he knew it would only hurt him even more emotionally. He would repeatedly give excuses or evade McGarrett's persistent questions about the true identity of Shelburne. As a result, McGarrett, despite seeing him as a father figure, regards him with some distrust.

Governor Sam Denning

Portrayed by Richard T. Jones

Governor Samuel "Sam" Denning was Lieutenant Governor of Hawaii and replaced Jameson after death. He is much more "by the book" and withdraws his predecessor's assurance to the Five-O Task Force of "full immunity and means". Instead, he brings in former federal agent Lori Weston as a "spy" to keep McGarrett and the rest of Five-0 in line, much to their displeasure. However, he does vouch for and backs McGarrett when necessary. For example, he dismisses Lou Grover's complaint against McGarrett in season 4 and instead forces the both of them to serve a warrant together.

Nahele Huikala

Portrayed by Kekoa Kekumano

In the episode "Poina ʻOle / Not Forgotten", Nahele was first introduced as a homeless juvenile delinquent who stole McGarrett's prized vintage Marquis and stripped it for scrap metal. McGarrett decides not to file charges after learning that Nahele was living on the streets after running away from his abusive foster home and that his only parent, his father, has been in prison since he was eight. Kamekona agrees to let Nahele work for him as a waiter at the shrimp truck as part of the agreement that McGarrett will not file charges if Nahele keeps his end of the bargain to stay out of trouble. Since then he has looked up to McGarrett as a mentor and older brother figure. In season 6, his father is released from prison and successfully files for custody of him. Distraught, Nahele confesses a long-buried secret to McGarrett explaining why he still refuses to see his father even though the latter turned his life around.

Dr. Charles "Charlie" Fong

Portrayed by Brian Yang

Charlie Fong is a forensic scientist with the Honolulu Police Department Crime Lab. He provides evidence analysis for the Five-0 Task Force. He attended the prestigious Punahou School and is a childhood friend of Kono.

Ellie Clayton

Portrayed by Mirrah Foulkes

Ellie Clayton is a lawyer and Deputy District Attorney introduced in the season 5 premiere. She emigrated from Australia with her father Paul as a child. Her father owned a bar called "Aces High" but was shot and killed in a botched robbery nineteen years ago. A homeless man was prosecuted but the case eventually went cold due to the lack of credible witnesses and evidence. She graduated from law school and returned to Hawaii. In several episodes she had aided the Five-0 Task Force in securing arrest warrants or provided advice.

McGarrett meets her by chance when he sees her putting flowers on his father's grave and accosts her. She reveals that John was the uniformed officer who responded to the scene of the crime. Every Christmas since then he would visit her and give her a present. According to Chin, John made an effort to keep in contact with her, partly out of guilt and regret for sending his two children away. Ellie reveals that prior to his death, John had called her up to tell her that he had found new evidence. McGarrett recalls finding a "Aces High" matchbook in his father's Champ toolbox and decides to reopen the case in his memory. Danny proposed Ellie as a potential love interest but McGarrett quickly shoots down the idea, saying that due to her connection to his father, they could only be friends.

Criminals

Main antagonists

In the 100th episode, he kidnaps McGarrett and tortures him with a heated cattle rod and truth serum. After a bitter fight to the death, McGarrett kills him with a bullet to the head.
• Victor and Anton Hesse (James Marsters and Norman Reedus) are brothers and criminals heavily involved in the illegal arms trafficking trade. During his days as a SEAL, McGarrett was part of a task force which had been investigating and tracking the Hesse brothers for several years. He and his buddy Freddie Hart were sent into North Korea on a classified operation to kidnap Anton Hesse but Hart was killed and Anton was eventually killed when the convoy he and McGarrett were being transported in was attacked.

Victor later resurfaces and is eventually caught and sent to prison where he is killed by Wo Fat who was posing as a corrections officer.
• Gabriel Waincroft (Christopher Sean) is the younger brother of Malia Waincroft, the late wife of Chin Ho Kelly. As an adolescent he repeatedly got into trouble with the law and Malia went to Chin, then her boyfriend, for help in setting him straight. Gabriel was initiated into a gang after killing Chin's father and rose through the ranks of the (fictional) Culiacan cartel based in Sinaloa, Mexico.^[34] With Wo Fat's death, Waincroft is now the team's primary antagonist. He has been described as daring and ambitious, particularly after he had his men attempt to assassinate the heads of three different criminal syndicates during a high-profile boxing match (the attempt was discreetly foiled by Five-0), in the episode "Ka Makau kaa kaua / The Sweet Science".

Recurring

He chooses to be transferred to Halawa to be nearer to his young son. His appearances are often met with annoyance by the Five-0 team as he would mock McGarrett and Kelly, try to rile Danny up or crack inappropriate jokes at Kono. He does provide valuable and much-needed intel for the team on several occasions.
• August March (Ed Asner) is a renowned diamond smuggler who was jailed for over three decades. Ed Asner portrayed the character in the original series and was one of several actors who returned to the 2010 reboot.^[1]

The Five-0 Task Force crossed paths with him while investigating the murder of an undercover ATF agent in the episode "Ua Nalohia / In Deep".
• Detective Kaleo (Jason Scott Lee) is a corrupt former Honolulu Police Department cop who was imprisoned for his involvement in the murder of fellow cop Detective Meka Hanamoa, who was the partner of Detective Danny Williams. He was initially housed in protective custody due to his former occupation but was sent to "general population" after he aided his brother Daryl in the trafficking of conflict diamonds, indirectly causing McGarrett's sister to be coerced into becoming a mule.^[11]
• Frank Delano (William Baldwin) is a corrupt former HPD homicide detective who founded his own criminal syndicate comprising exclusively of former cops. After Kono was "fired", Delano recruited her into the syndicate. Unbeknownst to him, it was part of Captain Fryer's plot to arrest Delano and his associates.
