>>48181963i think they want them all to be easily recognizable
so having anything that so dramatically changes their appearance seems like it would be ng
the only instances of this were Rushia getting the pink hair which didnt have any negative effects and the AZKi and Aruran makeovers also which seems to have been a boon for both of them, though i think people still prefer OG Aruran. but they were all still pretty recognizable
