Cumber

Cumber is an ancient Saiyan. He is taken from his proper timeline by Fu and placed in the Core Area of the Prison Planet, restrained by the use of a straight jacket and is given a Special Dragon Ball. The purpose behind Cumber’s capture is to study and experiment his unique dark ki.

Cumber appears to have some bad history with the Super Saiyan God as once he first saw Goku turn Super Saiyan God, he became very agitated at the presence of a red-haired Saiyan. In the arcade game of Super Dragon Ball Heroes, it is revealed that Cumber was summoned by the Dragon Balls after Fu makes a wish with them.
