Zhilei Zhang

Zhilei Zhang, better known as "Big Bang", brings a 27-3-1 record into every walk to the cage — and in a division as crowded as heavyweight, every single win matters.

The style is simple and terrifying: 81% of his wins never reach the scorecards. When he touches people, they fall — 22 knockouts and counting. Add the southpaw stance, and the puzzle gets harder still.

He's coming off a loss to Agit Kabayel. Careers aren't defined by the fall, though; they're defined by the rebound.

At 43, the window is what it is — which tends to make every remaining fight more honest, and more dangerous.
