Zangief

Zangief is normally seen as an anti-hero from the popular Street Fighter series, however in some other media related to the games he is portrayed as a henchman of higher villains or (rarerly) a villain in his own right.

Street Fight Alpha: The Animation
Zangief is an outright villain in this feature length movie, where he is depicted as a near-feral monster who was more than happy to try and brutally murder a young boy after the boy angered him - he was so brutal that Ryu had to intervene to stop him potentially killing his opponent and although Zangief did show some minor signs of fear after Ryu almost killed him using dark energy he never redeemed himself, in fact he fell down a pile of debris and was not seen again in the movie
