Renegade Extra: Royal MJ Opal

"You're talking to the Daughter of a gem who chalenged Diamonds. I'm not afraid to fight for a just cause."
The first (and for a long time only) ally of the renegades, she didn't officially join the team until much later. She sometimes serves as the team leader due to her years of experiance in a leadership role.
Currently this is more of a what if member, since I'm no where near close to planning this far in the future. But I do feel MJ will join the Renegades at somepoint.
