Episode 222 Spoiler!
Episode 222 that had Gajeel and Panther Lily dress up as Batman! And Erza Cat Woman funny thing is she said she was a Superhero though she copying off of a super villain. but called herself "Fairy Woman". I think Gajeel and Panther Lily called them self Batman at one point the Episode. Which Lucy could have learn how to Transform though. It would be cool if she learn how to do it...
