Randall Boggs

Randall Boggs is the slimy dragon who one of the main villains in Monsters, Inc. He was working for Mr. Waternoose who wants to boom up business in Monsters Inc by using the Scream Extractor to suck out kids' screams. However, his initial plot was failed due to Sulley being sent by Mike after closing hours to recover paperwork to turn them into the desk after Mike forgot to turn them in and stumbled upon the kid who Randall was supposed to pick up first, whom Sulley nicknames her Boo. After Mike and Sulley are exiled, Randall and Waternoose go through with testing the scream extractor on Boo (although Waternoose expresses distaste for having to exile Sulley and Mike due to Randall's negligence, as well as pointing out that Sulley was "twice the scarer [Randall] could ever be"). After Sulley manages to escape and wreck the Scream Extractor, Randall then tries to attack Sulley. He proves to be quite an adversary, due to his cloaking abilities. However, when Mike gets annoyed with the fact that Sulley is not listening to his apology, he throws a snowball at him, but it hit Randall instead, and that is when the partners realize that Randall was attacking Sulley. He is defeated after a chase through the factory, where Boo and Randall escape into a door, and Boo begins to hit him with a baseball bat, making him turn different colors, then Sulley restrains him with a chokehold, followed by a snake wrestling maneuver, with the final blow being to throw him through a door that banishes him to a trailer in the middle of a swamp in the south.
