Hmmm

Stone ocean anime uses loony tunes characters, not disney characters since hermes mentions bugs bunny's birthday in anime, and mickey's birthday in manga

Warner bros characters might be able to come, since Warner bros is helping the localization and all.

Actually, many would show up since all of them but Spider-Man were folk tales that have no copyright. They aren’t own by Disney or anything, that’s why Mickey didn’t show up because even though Araki wanted to put him in he was afraid that Disney would sue him.
