Group way in back, in the center. Juggernaut, Thing, Iron Man, Beast, PC Hammer, Jay Garrick, someone in a Moldiver suit, and Bruce Banner.

Back row. I'm guessing Utena, Kurt, unknown (I can't make out the emblem) Etrigan, Robin, Colossus, Greg from CSI, Geoff, Logan, the Power Puff Teens, someone I can't recognize with a white streak in her hair, unknown guy with goggles, Archangel, Terra, Beast Boy, Jen Walters (or a female skrull), Janice?, and Daredevil.

Row 2. Alan Scoot, Starfire, Captain Marvel, Mary Marvel, Catwoman?, Cyborg, unclear, Mayl?, Hawkgirl, Corwin, Yomiko Readman, Raven.

Front row. Wakaba, Arsenal/Speedy, Stargirl, Flash, Wolfsbane, Mace Windu, Diana, Batgirl, Supergirl.
