Arthur Lopes

Nobody hands you anything at heavyweight. Arthur Lopes — "Demolidor" to fight fans — has built a 6-2 record the hard way, one fight at a time since leaving Brazil's regional scene.

On the feet he's a problem: 9.74 significant strikes a minute at 40% accuracy, and 83% of his wins end in a knockout. The math is bad for anyone standing across from him. Add the southpaw stance and a 77.5" reach, and the puzzle gets harder still.

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