I had:
Batman
Robin
Superman
Green Lantern
The Flash
I lost all three of the capes along the way, eventually even poor Batman's head went missing. I still have Green Lantern and The Flash though, they are sitting on my GL Shrine shelf.
Super Powers was great. I had the figures, the comics, and loved the SuperFriends TV show. Probably why I was never turned into a Marvel Zombie and can resist the siren song of the Marvel Legends figures... unfortunately, I can't resist the DC Direct figures, DC Pocket Heroes, DC Kubricks (thanks Kubrick Krazies for starting me on this one)...
