Ren Höek

Ren is one of the titular protagonists of Ren & Stimpy and also the primary antagonist of the show, while Stimpy is portrayed as sweet and gentle Ren is bitter and violent - to the point of being downright abusive, especially towards Stimpy.

Ren's violent behavior and foul attitude is heavily played upon in many episodes of the series, though he does have a softer side he rarely shows and can be remorseful when he goes too far - most of the time however Ren is a borderline psychopath with extremely volatile and disturbing behavior as well as a bullying nature.
