on a lighter note, what about characters that have never really had any other visuals.
specifically doomsday I mean he has always looked the same unless they want to give him his green suit from his first appearance. I wonder what his alternate could be? Or how about cyborg, he pretty much always looks the same minus a few gizmo's here or there?
Just alternate colors for GL. Doesn't even have to be a different lantern for me.
Also, cartoon Joker. Like, different artstyle. Like how there was Cartoon Batman in Arkham City, I want this:
Oh, and of course the obvious, Crime Syndicate / Antimatter Universe versions of all applicable characters. So Supez has Ultraman, WW has Superwoman, Batsy has Owlman, GL has Power Ring, Flash has Johnny Quick, Shazam has Captain Super, Joker has The Jester, Luthor has... Luthor, Deathstroke has President Slade Wilson, etc. There's probably more but I'm too lazy to find them.
