Even if it's a shared universe specific categories like Spider-Man Villains: Dr. Doom for has fought most Marvel's heroes including in at least one issue Spider-Man but he's listed Marvel and Fantastic Four not Spider-Man or every hero he's ever faced because they aren't significant for his character or his primary foes.

As for villains in crossovers like Kingdom Hearts at absolute max it's crossover and Kingdom Hearts and even then I fell Sephiroth should simply have crossover as he doesn't play a significant role in those games.
