Yeah... I figure it's time to make an inventory here, how big IS Superman's world, and how big COULD it be?
Here's my quick list off the top of my head:

Lor-Zod (chris Kent ak a Nightwing III -rebooted, villainous
STATUS UNKNOWN

Comet the Super-horse (possibly repowered)
New Super-Man (kenan kong)
Strange Visitor (kismet?)
Superboy II (kon-el, soon to return)
INACTIVE
----------
Power Girl (trapped between realities)
Power Girl II (trapped between realities)
Superwoman IV (lana lang, depowered)
Cyborg Superman II (zor-el, killed by jor-el)
Superman's Rocket ("brainiac"? from morrison's run - may not exist)
Flamebird II (Thara Ak-Var, inexistent)
Matrix (supergirl II, inexistent)
Cir-El (supergirl III, inexistent)
Beppo the Super-monkey (inexistent)
Feel free to correct me and help fill up the list. Which character would you like to see brought back? And in what way? How can they be either modernized or tweaked into a different niche? (some characters fill up the same niche, which is problematic)
And wow... looking at the inactive list, there's a lot of characters DC Comics have just... outright SCRAPPED! : [ I feel this isn't really the right move to make, just scrapping characters for various reasons, isn't a very productive means of doing business, imho. Preserving them in some capacity, even if hardly ever used, seems like the better move - one never knows when one of these characters could have a good story!
