Randall "Randy" Boggs is the main antagonist of Monsters, Inc. He is a purple, lizard-like monster who worked for the company as a scarer and he'd hired Mr. Waternoose to help him with his machine problem.
Randall resembles a lizard, with the ability to change his color from purple and blue to blend into his surroundings at will, much like a chameleon, making him invisible.
Randall hired Mr. Waternoose to kidnap human children and test his invention the Scream Extractor on them. After Sulley and Mike rescued Boo, Randall chases them into the factory door system, he manages to recapture Boo then he flees into a door hundreds of feet in the air Randall ambushes Sulley making him dangle for dear life on the door. Randall starts teasing Sulley while he hangs on the door as he smashes Sulley's fingers with his feet, he almost succeeds in making Sulley fall to his death, but Boo starts pulling on his antennas and hits him with a baseball bat. Sulley takes it from there and throws Randall into a door leading into the human world, and then the door is destroyed to prevent Randall from coming back the way he came.
Randall is set to return in the prequel.
- Randall is constantly thought to be the secondary antagonist of Monsters, Inc., as well as Mr. Waternoose's henchman.
