I like the idea of being the Great Fairy, Darmani and Nabooru. Two of them are in Majoras Mask, one which who also appears in OOT as I am using that design or more likely the updated one from HW. Also the Nabooru is also from OOT. The one from MM has no name.

Darmani will probably be support at most and similar to Navi but not in her kind of way. The Iron Knuckle will be this character that goes to and from what its current form. The Great Fairy will probably be the wander/I have no what to do with this character type of character.
