Death Bear

Death Bear is a minor villain of the 2010 Cartoon Network animated series Regular Show. He appeared in the titular episode "Death Bear" as the main antagonist. 
15 to 20 years prior to the event of the episode, he was a troubled bear who lived in the Park Zoo. One day, out of nowhere for undisclosed reasons, he killed his trainer. The zoo was forced to close down because of this, but Death Bear refused to leave. Thus, he was left to roam the abandoned zoo, growing more evil over the years and surviving by breaking into people's homes, eating off on their food and then the resident themselves. 
When Mordecai, Rigby, Margaret, and Eileen travel to the abandoned zoo to take a picture of the group in its cage, they are ambushed by Death Bear, who chases them all the way back home to kill them. Here, they call animal control to trap Death Bear, but they are unsuccessful. Death Bear then attempts to kill the gang but Mordecai keeps firing tranquilizer darts at him, which seem to have no effect on the beast, until he suddenly falls down asleep.
Death Bear is then taken to an animal sanctuary, where he would be in better living conditions.
