Johnny Worthington the Third

As president of RΩR, the premiere campus fraternity, Worthington is very selfish, egotistical and only interested in having the "highly elite" Scarers in his fraternity, inviting James P. Sullivan to join, as the latter comes from a family of successful Scarers, but mockingly denies Mike Wazowski and suggesting he joins a fraternity that's "more his speed".

Worthington clearly cares more about his fraternity's reputation (taking grades and academics into account), when he threatens to kick Sulley out of RΩR if he loses to Mike on the final exam. When Mike and Sulley are both kicked out of the Scaring Program by Dean Hardscrabble, Worthington and his frat-boys leave without a word to Sulley.

Worthington's rivalry towards Mike escalates when, right before the Scare Simulator, Worthington arrogantly tells Mike not to take losing so hard and that "he never belonged in the Scaring Program anyway." Mike wins the Scare Games due to Sulley's tampering of the settings, thus humiliating and surprising RΩR in its defeat. Worthington is not a sore loser as he admits defeat, offering Sulley back to their group in Randy's place only for Sulley to reject his offer and give him the trophy since he is more concerned in rescuing Mike.

Despite Worthington's arrogance, he has something to lose, is afraid of failure and has a tradition to live up to. He is a Satan-like monster with purple fur, two upward-facing fangs (where his nickname "The Jaw" originates from) Jam colored eyes, and a muscular body

Johnny is mischievous and barging through doors to scare ppl for fun but ends up accidentally being in his favorite person's bedroom,, he's geeking out like crazy and trying to hold in his excitement because he’s a frat president and needs to keep it together.

He also does Door jamming when he drunks and just barges in for shits and giggles.
