delete Undead Villains, replace with :

Corporeal Undead (merge all these specific categories : Vampires, Liches, Mummies, Zombies, Skeletons)

Spiritual Undead (merge all these specific categories: Ghosts, Damned Souls, Wraiths)

then work on the "monster" category in a similar manner (delete specifics and merge Giant Monsters, Eye Monsters, Sea-Monsters.. a monster is a monster regardless of size or origin)
