They sound like characters from a bad action film. There's Dog the Bounty Hunter, who has publicly vowed to track down a fugitive mixed martial arts fighter named War Machine, who is accused of a vicious assault on his ex-girlfriend.
But that is the ugly situation confronting Las Vegas police, who have issued an arrest warrant for 32-year-old War Machine after his ex-girlfriend posted images of her battered face and body on social media.
Police say War Machine, who was formerly known as Jon Koppenhaver until he legally changed his name in 2008, is wanted on suspicion of domestic battery, strangulation, lewdness, assault and coercion in the alleged attack early on Friday.
Both War Machine and his ex-girlfriend, Christy Mack, are porn actors, and broke up in May, while War Machine previously appeared on the reality show The Ultimate Fighter.
Ms Mack posted photographs and a statement about the alleged attack on her official Twitter account on Monday, saying War Machine had beaten her so severely that she feared for her life.
The attack left her with broken bones, a ruptured liver, missing teeth and swelling and bruising all over her body, she claimed. She said there was a $10,000 reward for his capture.
While police have issued a warrant for War Machine's arrest, that was not enough for Duane "Dog" Chapman, who features in the reality television show Dog the Bounty Hunter.
Chapman, who has no apparent connection to the pair, took to Twitter to issue an ultimatum to the fugitive.
Ms Mack claimed in her statement that War Machine showed up unannounced at her house at 2am on Friday, found her and her friend unarmed, and beat her friend without uttering a word.
Ms Mack claimed War Machine sent away the friend and turned to her, forcing her to shower before knocking out some of her teeth and breaking bones in her face. She wrote that she feared for her life as he sawed off her hair with a dull knife.
She said she was able to eventually escape out a back door and run naked through her neighbourhood, knocking on doors until someone helped her get to a hospital.
She accused War Machine of being abusive in the past.
"After many months of fear and pressure to keep this man happy, I feel that I can no longer put myself in this situation," Ms Mack wrote.
The welterweight fighter made his Ultimate Fighting Championship debut during the 2007 season of The Ultimate Fighter, but he didn't last long for the promotion.
He lost his only pay-per-view bout in 2008 and moved on to fight for a variety of MMA promotions over the past five years. He fought three times for Bellator last year, losing his final bout in October 2013.
War Machine also took to social media to defend himself, claiming he had only gone to Ms Mack's house to propose to her. He appeared to suggest that a man was also at Ms Mack's house.
I'm not a bad guy, I went to surprise my gf, help her set up her show and to give her an engagement ring and ended up fighting for my life. — War Machine (@WarMachine170) August 11, 2014
