Devil Dinosaur

Devil Dinosaur is a red Tyranosaurus Rex that has lived since prehistoric times.

S.I.L.E.N.T.

Devil Dinosaur was recently revealed to be the criminal mastermind behind the terrorist organization known as S.I.L.E.N.T.. He has been using S.I.L.E.N.T. to field test unusual weapons of mass destruction (UMDs) in order to kill all the monkeys with their constant chatter and noise. He wants to return the world to a more peaceful time, to more Jurassic values.

He used to be paired with a prehistoric man named Monkey Boy until Devil Dinosaur realized that Monkey Boy treated him like a dumb animal. He ate Monkey Boy.

Devil Dinosaur was presumably killed when the Nextwave Squad kicked a spherical structure Devil Dinosaur was standing in off of State 51 and into a valley were it exploded.
