Hmm...yeah, like offer them jobs in the park, and then use the "cure" as a means of blackmail, like "If you work for me, I will give you this cure.." or something to that effect. Also, the memory pills Lavender suggested would be used to give the newly minted transformee the option of having their minds match their new forms, if that is what they choose..
So, what is the theme? Superheroes/Heroines? Anime/Manga Magical Girls? Video Game characters? A little of everything?
Sadly that rpg where I played Rukia Kuchki from Bleach didn't last too long. I was hoping we'd get to see the characters use their powers/knowledge from their respective shows, maybe fight their respective villains from their shows (ie, Rukia, orihime and the Hollows/Arranacar, Ichigo Momomiya and the Cyniclons, Nami from one Piece and Captain Buggy or Baroque Works).
And that Naruto one was cool too. I have a medical ninja konouchi that would have been perfect for that one.
