I'd consider Ukanlos one of the most likely monsters to return (along with White Fatalis). Maybe they wanted to "repeat" 2nd Gen, with Akantor appearing in a game and Ukanlos in the expansion. Or maybe I'm trying to find logic where there is none, and the real reason for Uka's absence is that the Capcom Dart Thrower aimed a little too low, so we ended up with bloody Gypceros instead.
