By the time the Wonder Twins Zan and Jayna arrived from Exor, the ranks of the Justice League had just been increased with the addition of Red Tornado and Hawkgirl. All the members of the League were debriefing on their most recent mission (circa JLoA 148) when the twins arrived with the warning of an imminent menace.

The SuperfriendsIn a mission that took them around the world, the Super Friends banded with heroes from around the world to fight an alien menace. Hawkman and Hawkgirl joined forces with Owlwoman, a native american that had the ability to channel the powers of her ancestors. She was the obvious choice to pair up with the Hawks since they have a similar modus operandi.

Now, for clarification purposes, all the members of the Justice League (except J'onn J'onnz and the Phantom Stranger), up to and including Hawkgirl, were members of the comic book Super Friends Team (Zatanna was never a member, and Firestorm was part of the Super Powers Team). In addition, the Super Friends also included Robin, Zan, Jayna, and graduates Marvin and Wendy.
