I drew this several months ago for IGN.
Part of a really fun article talking about things we'd like to see in the new Smash Bros game.You can find it here: [link]
A couple obvious characters i included are Megaman and Cloud.
Keep in mind that ff7 was originally planned for the N64.Would still be kinda fun,though.
I should've added Arthur from Ghost 'N Goblins...
