Tai Tuivasa

Tai 'Bam Bam' Tuivasa is one of the most likable heavyweights in the sport, an Australian with knockout power and a personality to match. He exploded onto the UFC scene with a run of vicious finishes, climbing all the way into title contention while winning over fans with his cheerful, down-to-earth attitude - and his signature 'shoey,' where he drinks beer out of a shoe to celebrate a win.

In the cage, Tuivasa is all about power. He swings for the fences and lives for the highlight-reel knockout, like the walk-off finish of Derrick Lewis that capped a five-fight winning streak. A tough stretch against the division's elite has tested him since, with his record sitting around 15-10.

For newcomers, Tuivasa is heavyweight entertainment - big power, big personality, and the kind of fighter you find yourself rooting for whether you've followed the sport for years or are just tuning in.
