6 Craziest MMA Fighters Who Did The Most Unhinged Stuff
Forget the belts and the highlight-reel knockouts. The real entertainment in MMA happens when the cage door closes—and the fighters are just genuinely unhinged human beings. From eating pink lingerie on Instagram to holding submissions long after the tap and faking a military career before committing murder, these six fighters have done things so bizarre they make Conor McGregor look like a saint. Here are the craziest MMA fighters who ever stepped into the octagon.
Conor McGregor — The Dolly Incident That Injured Two Fighters

The Notorious one has a resume of chaos longer than his winning streak. In 2018, ahead of UFC 223, McGregor hurled a metal dolly at a bus carrying Khabib Nurmagomedov and other fighters, smashing the windows and injuring Michael Chiesa and Ray Borg, who were forced to withdraw from their scheduled bouts. He’s faced sexual assault allegations in Miami (later dropped) and Dublin (where a civil jury found against him). He’s also been caught on a bizarre interview rant, roaring down the camera that Max Holloway “won’t lay a glove on him” and calling Holloway “my son”. The man is a walking circus tent.
