Johnny J. Worthington

Johnny J. Worthington, III is the main antagonist in Monsters University. He is Mike's rival and the president of Roar Omega Roar. His antagonistic role in the film comes from him frequently belittling the Oozma Kappa fraternity.

Role in the film
As president of ROR, the premiere campus fraternity, Worthington is only interested in having "the most elite" Scarers in his fraternity, inviting James P. Sullivan to join, as the latter comes from a family of successful Scarers, but mockinglky denied Mike Wazowski and suggesting he join a fraternity that's "more [his] speed".

But as time went on, Worthington noticed how Sulley's grades weren't up to snuff and Mike was doing far better.

Worthington clearly cared more for his fraternity's reputation (taking grades and academics into account), when he threatened to kick Sulley out of ROR if he did not beat Mike in the final exam - When Mike and Sulley are both kicked out of the Scaring Program by Dean Hardscrabble, Worthington and his frat-boys left without a word to Sulley.

At the beginning announcements of the Scare Games, it is revealed Worthington had replaced Sulley with Randy Boggs because of his ability to turn invisible.

Throughout the games, ROR always came in first place but noticed Oozma Kappa kept overcoming the odds. When OK comes to ROR's party, Worthington "congratulates" them by dousing them in colored paint, glitter, flowers, stuffed animals, taking their picture, and posting it all over MU campus to humilate them further.

However, OK persists, until at last it boils down to ROR and OK in the Scare Game Finals. Worthington and Mike are last to represent their teams in the scare-simulator; before starting, Worthington arrogantly tells Mike not to take losing so hard, that "[he] never belong [in the Scaring Program] anyway".

Worthington makes a near-perfect scare in the simulator only for Mike to pull off a perfect scare, winning the Scare Games for Oozma Kappa.

After the games are over, Worthington finds the gall to invite Sulley back into ROR, only to be rebuffed.

It is revealed in the end credits that he would go on to a career in scaring at a company called Fear Co.
