I was trying to divide them into a group of seven variety's of Heartless. I came up with six, natural Heartless like Shadow, Darkball, Invisible, things like that, the magic users (like the musical heartless and Wizards), flying Heartless (Angel Star, Air Soldier, Air Pirate, Search Ghosts, etc.), fighters (Soldier, Wight Knight, Powerwild, etc.), heavy ones (Fat Bandit, Fat Body, Submarine one, etc.), and the mushrooms (White Mushroom, Rare Truffle, Black Fungus). I can't think of a seventh one, but I feel like one is missing, and I'd like seven to correspond to the seven Princess' of Heart. Anyone have any ideas on what the seventh group could be?
