LAS VEGAS (AP) — A mixed martial arts fighter known as War Machine was hit Wednesday with attempted murder, sexual assault and other new charges in Las Vegas in a case that prosecutors said stemmed from attacks on his ex-girlfriend.

The defendant, whose birth name is Jonathan Paul Koppenhaver, stood shackled and flanked by two police officers during a brief initial court appearance.

Koppenhaver was arrested Aug. 15 after his ex-girlfriend, adult film actress Christy Mack, posted Twitter photos of herself showing injuries she said she received when Koppenhaver attacked her a week earlier in Las Vegas.

Koppenhaver, 32, was extradited to Nevada from the Los Angeles suburb of Simi Valley, California, where he was initially sought on a warrant involving seven charges, including battery, assault, coercion and lewdness.

Koppenhaver, who legally changed his name to War Machine in 2008, told the judge on Wednesday that he understood the charges and would use the name Koppenhaver in court. He wasn't asked to enter a plea.

"I think the public will understand that War Machine's a character," Koppenhaver's lawyer Brandon Sua said outside court. "He is controversial and people need to understand where to draw that line from his character as War Machine and a person as Jon Koppenhaver, because that's who he is."
