Champ

Champ is generally happy-go-lucky in demeanor, believing firmly in the power of justice and fiercely protective of the ones he cares about. However, Champ can be hot-blooded and impulsive when provoked, especially when his friends are endangered or hurt. When he encountered Stinger, the man who the wrestler thought killed Dr. Anton, he fell into a fit of rage and had to be restrained by his teammates, unintentionally causing his team to be poisoned. When not fighting, Champ will usually be lifting weights, despite the fact exercise gives him no physical benefit due to being a robot.

Despite his animosity towards Stinger until he realizes that Stinger's traitorous brother Scorpio was the one who murdered Dr. Anton, Champ eventually warms up to him as a teammate and friend (calling him 'partner' too as if they were already close best buddies), to the point where he takes a finishing move meant for Stinger and is destroyed. After being revived they got along well and supported each other as needed.
