I have a question or two about a character I'm thinking of bringing in.

He's pretty much a magic boy with a ring that lets him become a superhero who has a one-shot destructive touch (which I plan on using as his power). My question is since the thing that gives him powers is technically a living, talk, sentient cat-god creature named Plagg bound to his ring that only exists when he wears the ring is he going to have Plagg or is he going to have to be a regain or something? Plagg isn't a pet and he doesn't interact with anyone other than Adrien. And if he does have Plagg will he be able transform back and forth from Chat to Adrien?

(I'm also asking this on behalf of the Marinette player that expressed interest in joining because Tikki.)
