Dr. Cockroach, Ph.D. is a brilliant professor and a mad scientist with the head and abilities of a cockroach. He created a device that would give humans a cockroach's ability to survive forever. He tested it on himself and found that there was a side effect of giving him the head and abilities of a cockroach. He can climb high walls and objects and digest garbage. He was captured in 1962 and put into the recently set up monster prison in Area Fifty-Something.

Dr. Cockroach is voiced by Hugh Laurie in the film and Chris O'Dowd in the TV series.


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. He has a big sense of guilt when he makes a mess.

Behind the Scenes

Dr. Cockroach is a parody of Andre Delambre from the 1958 film The Fly. His human appearance was based off actor Vincent Price, who also starred in The Fly as Francois Delambre, brother of the ill-fated protagonist and who was know to play a mad scientist.
