Ralph (We Bare Bears)

Ralph is one of major (episodic) villains, in We Bare Bears series. This Yeti is memorable because of his brute and sometimes, too cold-blooded behavior to humans.

 He was voiced by John DiMaggio, who also voices: Joker, Jekhide, Dr. Drakken, Hannibal McFist, and Bender.

Story
Ralph is extremely overconfident, not considering the well being of others to the point he would even be willing to kill others for his satisfaction of what he perceives as "fun". He doesn't even care about humans saying there are so many of them and a few of his and Charlie's species and it's not bad to "lose a few" for a "laugh." Ralph doesn't consider people to be cool to his standards and even left Charlie to die while holding a bridge because he was being a "snooze fest".
