He is also called the Grasshopper, the 'Dumb' brother from the Dumb and Dumber pairing with Daesung and as part of the Nation Siblings with Hyori. Jaesuk is oftentimes talkative, relying on his quick wit for observational humor, and excels at articulating emotions and situational context, such as game rules to audiences.

He is viewed as the best at "making the seasoning" for cooking on the show with the addition ramen noodle powder to soups. He is often called sickly, old man, and Forty Brothers with Kim Su-ro. Yongshin is usually seen as the least physically gifted and thus last chosen for physical competitions, but exists as a strong competitor for oral battles involving wit.

The Game Devil of the show for his strong physical performances.

Sooro is one of the more strong and athletic family members when participating in games, leading to the use of the Imperial March theme song.

Far from his national-idol-Big Bang image, the youngest of the family members assists Yoo Jae-suk in gags and is seen as a younger brother to him. He's called the 'Dumber' brother with Yoo Jae-suk's Dumb and Dumber, as his IQ is revealed to be among the lowest in the family. He is also called Small Eye Brothers with Kim Jong-kook. Daesung is shown to be easily intimidated and shy, particularly by group member guests.

Initially portrayed as a strong physical competitor, Jongkook is revealed to have poor luck and is in a perpetual "game slump". Frequently called "Kim Kook-jong" on the show when being teased by Jaesuk and Hyori. Jongkook's character evolves over the course of the series as he becomes more talkative, allowing him to exert himself over Jaesuk and Jongshin with wit and strength, particularly during chores and cooking activities. Originally having an awkward relationship with Hyori and Yejin, they later develop into "romance scandals"; Jaesuk would also frequently tease Jongkook further by including Yoon Eun-hye in the scandals.

He often retorts Jaesuk and shows both gullibility and ingenuity. He is sometimes called the unlucky man because of his constant failures during games, which he always explains otherwise, having a substantial stock of justifications. Soo-Ro confirmed that Hae-Jin may be even more clumsy than Chun-Hee. He is occasionally coached by Jong-Kook to develop strength.

Inhabiting the image of Chunderella and Clumsy Chun-hee, he originally appeared to be a strong player, but was later determined to be naive and clumsy. Consequently, his theme music was frequently played during his moments of incompetence (Childhood Memories, Once Upon a Time in America theme). He is constantly picked on by Sooro, his senior from acting school, despite his futile attempts to "rebel" from time to time. (See: Stepmother Kim and Chunderella). He follows stepmother Kim Soo-ro's footsteps upon the arrival of guest Lee Jun-ki, a junior from university, by bossing him around. Chunhee is revealed to have a high IQ and to have been contacted by Mensa. He is also the only member who possesses a scuba-diving license. Chunhee expresses his adoration for multiple female guests who join the show such as Taeyeon and Son Dam-bi, without reciprocation.

Originally seeming as a pleasant, demure ladylike figure, she later showed her true colors as the Sweet and Vicious or Sweet and Savage Miss Ye-jin through her no-nonsense and tenacious ways in preparing fish and chickens for meals, as well as her bravery towards capturing them. Yejin maintained a strong rapport with Hyori as they ranked the Family men for sleep positioning; when female guests appeared, they banded together as the two were cast off as the undesirable "older sisters". She was known for expressing joy and excitement with her high pitch nasal screeching. . Yejin demonstrated her mental fortitude when admonishing Jaesuk during food preparation and her physical acumen in battling and hair-pulling against the strongest of competitors. The love scandal between Yejin and Jongkook was further heightened when they filmed a music video together.

Giving the image of a City Girl, she has become close with Hyori on the show. She is referred to as of the Park Siblings with Park Haejin.

As the very first breakfast pair, Dae-sung and Yoo Jae-suk had trouble with measuring the water for cooking ramen. As said in the episode, you can't help but call them "dumb and dumber". Yoo Jae-suk is referred to as "Dumb" and Dae Sung as "Dumber". It was later shown in one of the nighttime games that Yoo Jae-suk has an IQ of 114 and Dae-sung has an IQ of 110.

The pair plays the role as a rich couple Madam Lee and Chairman Yoon. Yoon Jong-shin seems to act naturally but Lee Hyo-ri seems to dislike her role.

During the 7 Step Running Game, Lee Chun-hee lost in a bet against Kim Su-ro. The bet was if Lee Chun-hee wins Kim Su-ro will stop with the ordering around but if Kim Su-ro wins Lee Chun-hee must immediately follow his orders. Kim Su-ro is the senior of Lee Chun-hee from university, as well as in acting. When Lee Chun-hee is asked to perform a task, he naturally does so. Lee Chun-hee attempts slight revenges but usually fails.

As the only two female cast members at the time, the two needed to stick together against the men. Generally they treat each other well, but during games or voting for where to sleep, they "fight till death".

By 2009, when Kim Su-ro turned 40, he was referred to as thus. Through the role as Forty Brothers, the two finally referred each other as "brother" after 7 months of filming in an awkward stance.

The two have similarly small eyes. Kim Jong-kook has used Dae-sung to help him improve his relationship with the women of the family.

Yoo Jae-suk often provokes and teases Kim Jong-kook during games, resulting in Kim Jong-kook lashing out to him. This makes Yoo Jae-suk (and sometimes Yoon Jong-shin) to seek revenge and sees Kim Jong-kook as a game rival, however often ended up getting beaten up by Kim Jong-kook.

After Lee Chun-hee left, Lee Hyo-ri and Park Si-yeon are the only two members in the family born in 1979. At first they were not great friends, but has created a bond throughout the show. When it comes to games, it seems that Lee Hyo-ri overpowers the timid Park Si-yeon.
