I seriously doubt the Sky Pirates will return, since they're not really "ninja allies" and most of the team don't know they exist. But if they were needed, it could be a possibility. Tjhe Realm Crystal is in Hiroshi's Labyrinth. Also only Kai and Cole don't know about the Sky Pirates' existence. Lloyd has a form of deja-wu and Nya programmed the events back to Zane is S7.
