I went ahead and watched a bunch more of his fights. Jeez, what a fucking arm. He makes bitches out of both MMA guys and jujitsu fighters and pro boxers. Pretty impressive. There is this one fight that goes on for 15 minutes and he pretty much loses from exhaustion.
Dr Dim He didn't beat any really skilled opponents except maybe Hugo Duarte... most of his wins were against other brawlers. His overall record is a less than stellar 9-14-0 now, but he was pretty awesome in the 90s.
