Dr. Cockroach (or Dr. Cockroach Ph.D) is the overall deuteragonist of the Monsters vs. Aliens franchise. He is the tritagonist of Monsters vs. Aliens, one of the three main protagonists (alongside B.O.B. and The Missing Link) of B.O.B’s Big Break, one of the three deuteragonists (alongside B.O.B. and The Missing Link) of Monsters vs. Aliens: Mutant Pumpkins from OuterSpace, the deuteragonist of Night of the Living Carrots, and one of the three deuteragonists (alongside B.O.B. and The Missing Link) of the Monsters vs. Aliens TV series. He was once a scientist who invented a machine that would give people the ability to survive like a cockroach. Unfortunately, when he stepped into the device, he became half human, half cockroach and was sent to a secret monster prison along with Insectosaurus, B.O.B., The Missing Link, and Ginormica.
He was voiced by Hugh Laurie in the film and Chris O'Dowd in the TV series.
Powers and Abilities
He can turn a pile of garbage into a super computer as long as he doesn't eat it first, build a rocket car, and make missiles and explosives in his cell from nearly nothing. Also he was able to hack through the alien's core computer and set it to self destruct the ship.
Dr. Cockroach is an expert dancer (it happens to be his Ph.D) and a polite, charming and sophisticated man. He accepts his role as a mad scientist and is prone to burst into maniacal laughter in the middle of experiments and plans. He also helped Susan get used to the monster prison and to her new power and size as soon as she was captured and brought to Area Fifty-something.
He can be trapped when a giant shoe is on him.
When his vocabulary is lost, he speaks gibberish and goes haywire.
He has extra sensitive insect eyes.
Behind the Scenes
Dr. Cockroach is a parody of Dr. Andre Delambre from the 1958 film The Fly. In an attempt to perfect his Disintegrator-Integrator, A Canadian Scientist mixes his atoms, head and arm with a Fly. His Personality is a parody of one of the stars of the film, actor Vincent Price.
