McGregor became the UFC’s first true superstar when he broke onto the scene in the mid-2010s. The Irishman claimed two titles on his way to becoming the face of the organization. However, he also had a dark side and infamously suffered a suspension for his role in a post-fight brawl.
The seedy superstar is no stranger to controversy. He once flew his friends to Brooklyn to stage a raid on the Barclay Center in a scandalous event. The Irishman also experienced multiple legal battles about alleged sexual assaults, battery, and driving offenses (via GiveMeSport).
