Cockroach can be a bit insane at times as shown in the movie dancing maniacally on a dancing colour board that enabled him to hack into the heart/brain of Alien Spaceship causing it distrupt in limited minutes but survived with the help of Ginormica and the other Monsters. He was captured in 1962 and put into the recently set up monster prison in Area 52. He can climb high walls and objects and eats garbage. He tested it on himself and found that there was a side effect of giving him the head and abilities of a cockroach. He created a device that would give humans a cockroach's ability to survive forever. He was a brilliant professor and a mad scientist with the head and abilities of a cockroach.
