Cumber

Cumber, the evil saiyan is an ancient Saiyan interred by Fu on the Prison Planet. Cumber embodies all the battle characteristics of a Saiyan: violence, savagery, and an extreme desire to fight anyone he comes across. He has a tendency to demand battle with strong opponents no matter the scenario, even when on the losing end of a fight he's already in, such as when he was hit by Cooler's strongest attack and fell unconscious right after. He appears to have history with the Super Saiyan God form and may be an ancient Saiyan from an era where he fought against the heroic Saiyans, as evidenced when he became angry upon seeing Goku manifest the form. Cumber's battle lust establishes a level of respect for opponents who can match or exceed him in power, especially other Saiyans. Strangely, Cumber seems to hold no grudge against Hearts, despite the God Slayer using him for his own gains. Despite being known as the Evil Saiyan due to his unique aura, Cumber may not actually be truly evil.
