During college, Felder began training in Muay Thai before later transitioning to mixed martial arts.[11] Due to his karate background, he was given the nickname "The Irish Dragon", a reference to his Irish heritage and fellow karate practitioner Lyoto "The Dragon" Machida. Felder initially pushed back against the nickname, but it caught on and he stuck with it.[9] After fellow UFC lightweight fighter Conor McGregor commented that Felder's surname was of German origin, Felder joked in January 2021 that he would use the nickname "The German Dragon" if he ever fought McGregor.[12]
