When it comes to MMA fighters, confidence is a major key to being able to walk into the octagon. But this guy, Jae Hyuk Heo's confidence level is at 1,000 as he sang Imagine Dragons "Believer" walking entering his fight over the weekend.
This guy made fans right off the bat, look at him dripping in swag. Oh, and what about him belting out that "Ye-Yeahhhhhhhh" at the end. This guy HAS TO WIN, right?
Let's fast forward to :20 into the fight.
Welp.....at least he didn't sing Nickelback.
