Beakman is obviously a badass. Look at that face:
Not only is he obviously bent of global domination, he also has the balls to pattern his hairstyle after the Bride of Frankenstein.
He obvious doesn't give a shit what you think.
He is able to force grown men into rat suits. He willingly allows children to handle possibly dangerous chemicals. He appears to have slain at least one lab assistant during the course of the show (
What the fuck happened to Josie?!?).
The man is stone-cold. Don't fuck with him.
Paul Zoloom, the guy who plays Beakman looks like a dead-eyed serial killer twisted by his time hosting a kid's show. His desire to be a serious actor unrequited, twisted, and shattered. His moral integrity destroyed, he is only a rejected role away from eating your face with some fava beans.
Also his middle name in Finlay, and he loves to fight.
