Not to be confused with the titular character of the show, Leave It to Beaver. In which case, see Beaver Cleaver

Cleaver Beaver is, as his name implies, a homicidal, cleaver-wielding beaver. Depending on the artist's interpretation, he may range from a simple armed beaver to a murderous a-a-angry beaver.

Like SEXY Dragon Cow, he too has tangled with the likes of Batman, Cthulhu, SEXY Dragon Cow herself, and many others.
