UFC champ Ronda Rousey is no fan of Cris "Cyborg" Justino, and she's not afraid to let anyone and everyone hear it.

Rousey was on hand for a Q&A during this week's "UFC: The Time Is Now" press event in Las Vegas, and she ripped into her competitor with unchecked vitriol. Rousey's barbs were particularly centered on Justino's past suspension for performance enhancing drugs.

"She's a fraud and she doesn't deserve to be part of this sport," Rousey said. "These women she's fighting against are so much more than she is and they deserve so much more than her. And this sport deserves a champion that's way better than her and if she tries to undo all the work I've done, then I'm gonna try to kill her with my bare hands and the only person that's gonna stop me is the referee."

In addition to steroids helping a fighter build a fraudulent legacy, Rousey also worried that their use in UFC could lead to a death during a match, saying, "I don't think she has the right to compete. Coming in on performance-enhancing drugs in MMA is the equivalent of walking in there with a weapon."

Rousey and Justino were slated to square off in December, but the latter has since dropped out, citing an ankle injury. In line with the rest of her opinion on Cyborg, Rousey was dubious.

"If your definition of injured is 'took too many steroids and can't make weight,' she must be pretty f***ing injured right now," she said.
