That's a good point. Not all of them need to or should be party members. Still, plenty would work. I feel like Camilo would still work, they could change his powers to be able to turn into animals, that'd be fun. If not he could turn into a tall body builder; although that'd be pointless because Luisa exists.Counter-counter argument: While I agree it would be a good move, I'd argue a lot of the madrigals don't have what it takes to be party members. Most of their powers (healing through consumption of food, superior hearing, impersonation of others) are non-combative by nature and would make them more liabilities in a fight. Though super strength and chlorokinesis could work as effective tools against the heartless.
