Professor Monkey-For-A-Head

Professor Monkey-For-A-Head (commonly referred as "The Professor") is an ingenious inventor with a simian grafted to his head, which seems to have a mind and feelings of its own. The Professor seems to have a civil relationship with his headmate, as he can not only translate what he says, but also enjoy a round of ping-pong and gourmet cooking with him.

The Queen's Servent
In "War of the Villains", Professor Monkey-For-A-Head was first seen as a servent to Queen Pulsating, Bloated, Festering, Sweaty, Pus-Filled, Malformed, Slug-For-A-Butt. He presented to her the ultimate universe destructor (which was in the shape of a banana due to the fact he couldn't "get that shape out of his head"). The Professor warned, however, that it would only work with TWO joined forces of evil. After making the suggestion of allying with The Dark Queen, Queen Slug-For-A-Butt was off to offer an alliance, which would later seal her doom.

Rule over Insectika
Ultimately shocked (but incredibly satisfyed) with Queen Slug-For-A-Butt's Death, The Professor reigned control over the Planet Insectika. His old collegue, PsyCrow, offered an alliance with him, which he was ever-so-giddy to accept. The Professor suggested that they first make a move in the jungles of Africa, in search for The Rare African Brown Lion.

In the Jungle
The Professor and PsyCrow went to Africa to fight Scar (who happened to be The Rare African Brown Lion) inside their mighty battle bug. The minute Scar pounced onto the war machine, The Professor immediatly gunned him down.
