From behind prison walls, former UFC comeptitor Jonathan Koppenhaver (known to mixed martial arts fans as War Machine) offered a sobering reflection on the sport that made him famous and the lifestyle that led to his downfall.
Speaking in his first extensive interview since his incarceration, the controversial star didn’t mince words about the dark underbelly of professional combat.
“At the end of the day, bro, MMA fighters are psychopaths,” War Machine stated bluntly during the conversation with the MMA History Podcast. “There’s some squares in the business, but most all MMA fighters are using dr**s, partying out of control. That’s just the lifestyle, bro… It’s just sin, sin, sin. D**gs, alcohol, pride, lust, banging girls. It’s just.. that’s the lifestyle. That’s how it is.”
The competitor, who earned recognition through the TUF reality series and competed in both the UFC and Bellator, spoke candidly about the wild environment he navigated throughout his career. He described training alongside some of the sport’s biggest names while simultaneously living a life characterized by excess and poor decisions.
War Machine’s early years in MMA saw him training at legendary gyms like the Lion’s Den under Ken Shamrock and later at Cobra Kai in Las Vegas, where he worked alongside stars like Jason “Mayhem” Miller and Joe Stevenson. The gym culture, he explained, was intense both inside and outside the cage.
“The problem wasn’t the people I was surrounded with. The problem was me. I was the problem,” he admitted. Yet he maintained that the MMA lifestyle itself creates conditions ripe for destructive behavior.
He compared the sport’s toll to that of celebrity culture more broadly, noting the prevalence of suicide and overdose among competitors and entertainers alike.
The conversation touched on the financial struggles that plagued early-career fighters, with War Machine revealing how he and fellow competitors resorted to questionable means to survive. From smuggling ste**ids across the Mexican border to working strip club security with a fake ID, the lengths fighters went to support their training were extreme.
Perhaps most striking was War Machine’s transformation since incarceration. He claims to have found Christianity in 2014 after reading books that challenged his worldview. “I was a psychopath,” he said. “I hated Jesus. And I never would have came to Jesus ever in a million years. But the fact is he’s real.”
In eleven years of incarceration, War Machine reports zero fights and zero disciplinary write-ups—a remarkable record for someone with his violent history. He attributes this change entirely to his religious conversion, describing how his pride finally died after walking away from his first prison altercation.
War Machine’s warning about MMA competitors being “psychopaths” speaks to the mental toll of a profession that requires controlled violence, the constant pursuit of victory, and a lifestyle that often glorifies excess while providing little financial security or mental health support.
