Ayup, agreed. Canon, I'd say
To get some structure into this, I think we should focus on one group of chars at once and I propose the Justice League.
So far we have Ultimate takes on Batman, Wonder Woman, Martian Manhunter and Superman. Who else is in the Ultimate League?
Well, do we want the Ultimate JL to be the Big 7 (9?) (11?), or a mass organization like it is in the JLU seasons of the cartoon? Somewhere in between, with the elite, classic team and several spinoff/supporting teams (Young Justice, JLI, JL: Europe, JL: Antarctica, etc.)?
Flash is an obvious one, and I've got a couple ideas there, though I love hearing what other people come up with. We have a nice barebones Green Lantern, but the GL background got bogged down. Who else?
Well, let's apply MnM logic
. We've got a Crime Fighter, a Warrior, a Paragon, a Shapeshifter, and I'm assuming a Speedster and an Energy Controller. What niches haven't been filled? Mystic, Psychic, maybe a more tech-y type (Construct, Gadgeteer, Battlesuit)?
Chickens are a cruel people.
