ROR House

Roar Omega Roar, often shortened as RΩR, or by Rihannon, The Omega's is one of the six fraternities of Monsters University who appear as the primary Protagonists of Monsters United. It becomes the temporary rival fraternity of Oozma Kappa (OK) and the Allianced Fraternity to Human (HMN).

Official Description

 * The Roar Omega Roar (RΩR) fraternity is made up of not just the best scarers with proud family history, it consists of the strongest, smartest and the most determined. While the RΩRs may seem innocent in person, they are both tactical, ferocious and downright ready for any mission. Self-declared as the most elite house on campus, the RΩRs are led by Johnny Worthington and Riley Deroras, who presides over the house like 2 all-powerful monarchs.

Appearances
RΩR is the premiere fraternity on campus, run by Johnny Worthington, a self-assured monster with a long legacy behind him. When Riley arrives and later on invites Riley to become not just a member of RΩR but the special Vice-President that stands beside Johnny at all costs, Riley beams and accepts downright, making her the 7th RΩR member beside Randall, making RΩR the largest fraternity with more then 6 members.

During Season 4, Reggie moves away with his parents, thus making ROR once more six members. Though he moved away, Johnny made a plaque in his honour being a ROR and always being faithful and a member to his President.
