Chapter 1: Rage

Pain. Betrayed. That's all that, (Y/n) a powerful dinosaur faunus. But when his girlfriends, the only people that supported cheat on him and shun him, he feels betrayed and angered. Ozpina sees this and makes a stupid decision. She uses team RWBY and lures (Y/n) to a deserted island. And she tells team RWBY to beat him up so he doesn't follow them. Then they leave. It only gets worse. Ozpina made a deal with Ironwood, and a dust nuke is set off. But it doesn't kill him. It changes him. His body absorbs the energy, which in turn mutates him. Now, he seeks revenge, and his fury is directed at those who wronged him.
