Blackjack O'Hare is a fictional anthropomorphic hare in Marvel Comics. The character, created by Bill Mantlo and Sal Buscema, first appeared in The Incredible Hulk #271 (May 1982).

Blackjack O'Hare is a mercenary and leader of the Black Bunny Brigade. He was hired by Judson Jakes and Lord Dyvyne to kidnap Lylla, the C.E.O. of Mayhem Mekaniks. He planned on betraying his employers by marrying Lylla and inheriting the company, but was found out. He was rescued by Rocket Raccoon and after a series of incidents that caused him to question his own loyalty, he aided Rocket in defeating the tyrants and left with his new friends to start a new life.^[1]

All this appeared to be false when Rocket visited Halfworld and discovered that Blackjack, along with Lylla and Wal Rus, were all actually service animals for the mental patients who inhabited the planet. Blackjack married Lylla after Rocket left to ensure the imprisonment of a dangerous criminal.^[2]

However, this story was immediately retconned as Blackjack returned as a mercenary and adversary to Rocket and Groot. Blackjack was once again working for Dyvyne with his next assignment being that he kidnap Princess Lynx. Rocket, Groot and Wal Rus arrived to defeat Blackjack, his brigade and Dyvyne, once again.^[3]

He turned up again, disguised as an impostor Rocket and framing him for a series of murders.^[4] He reveals his identity to Rocket and claims that the reason for framing him was that he ruined his chance to assassinate Princess Amalya and destroyed his reputation in the process. Ironically, Amalya had become a "General" and arrived with Rocket's ex's in an effort to exterminate him themselves. Blackjack considered the possibility of assassinating her now, but was shot by Amalya because he was talking out loud. As a last ditch effort he fires a missile at Rocket, but it gets deflected and Blackjack is presumably killed.^[5]

Overrider

Overrider (Richard Rennselaer) is a fictional mutant in the Marvel Comics Universe. His first appearance was in Captain America Annual #8.

Richard Rennselaer is a former S.H.I.E.L.D. agent whose son developed nuclear psychosis, a total withdrawal from reality due to a fear that the world will end at any moment due to nuclear destruction.

Desperate to help his son, Rennselaer (secretly a mutant with the power to control machinery) took on the codename of "Overrider" and stole the experimental TESS-One robot - part of a 1939 project dubbed Total Elimination Of Super-Soldiers which was intended to be a failsafe against the Super Soldier program. Overrider had the TESS-One robot coated with adamantium at the Adametco Metallurgy company, and it was there he first encountered Captain America and Wolverine, each who had been following different leads. Overrider escaped with TESS-One, and later mounted an assault on a nuclear command facility in the hope of launching America's entire stockpile of nuclear missiles and burying them in the ocean floor, not caring that Moscow may interpret the launch as an attack on the Soviet Union. Captain America and Wolverine teamed up to defeat TESS-One, and then encountered Overrider as he was about to launch the missiles. Captain America knocked Overrider off his flying sled with his shield, and Wolverine almost impaled him on his claws as he fell, choosing instead at the last second to let Overrider fall to the floor. Overrider was quickly given medical attention and then taken into custody. Overrider was depowered thanks to the effects of M-Day.
