I can identify only these characters from the image above..
Top row (the hero row):
??? (Someone from Thundercats?)
Green Arrow (not 100% sure)
Martian Manhunter (not 100% sure)
Cyborg (not 100% sure)
Bottom Row (the villain row):
??? (I remember a ghost villain from Thundercats cartoon, but I can't recall his name)
Cheetah (Barbara Ann Minerva)
Lex Luthor (if villians on bottom row match with superheroes from top row)
??? (Looks Riddler to me)
Yellow Lantern (maybe, Sinestro)
Can you please identify them?
