A fictional character created by Al Gore in an episode of southpark. Gore creates manbearpig to get attention, and then later claims to kill him, thus making him the savior of southpark. Nobody cares.

A demon who is half man, half bear and half pig. It negotiates with gullible generations, giving them their deepest desires but then comes back to terrorize their land years later.

As predicted by Al Gore, who warned us about it but nobody paid attention to him.

Also a running gag in the famous adult cartoon, South Park.
