Antok is a member of the Blade of Marmora. He seemed to be the bodyguard or assistant of Kolivan. His appearance is broad and markedly bigger than Kolivan and the other members.

Though he is never seen without his mask, as a member of the Blade of Marmora it is clear he has Galra in him. However it is possible he may be only part Galra, as he has a tail (if it is not part of his uniform) as well as three-fingered hands.

He is killed during battle by one of Haggar's druids.
