@Supreme Marvel: @Destinyheroknight:
Wait a minute guys! You are all mis-informed. The solid definitions already exist, and usually are not played with, regardless of the latin/greek language construction.(This is of course strictly to literature, since that's what we're talking about.)
Omni-verse: All totality of fiction(movies, comics, novels, myths, etc...). It absolutely cannot reffer to one company's/writer's work.
Multiverse: A collection of universes(can reach infinite)
Mega-verse: A collection of multiverses(can also reach infinite)
@KingOfAsh: No, my friend. Heroman is not a part of Marvel, nor does it have anything to do with Marvel's works. The manga's rights go to Shonen, and the anime for Bones. So, even if they even make a cross-over, it wouldn't even be canon.
