Vovchanchyn's hands, calcified and raised like rolling hills at his knuckles, unveiled epitaphs for opponents for a decade. The "Ice Cold" Ukrainian, carrying 235 pounds on 5-foot-8 frame, ruled multi-fight one-night tournaments (often bare-knuckle) from 1995 through 1999, amassing a 37-2 record and a hit-list of KOs. He continued racking up wins and stoppages in Pride before leaving the sport for good in 2005.

Quintessential KO: Francisco Bueno, Nov. 21, 1999
