Del fuego he resurgido...
he didn't originate on Nintendo, sorry..if Snake is in it it's because the producer of the game practically begged Miyamoto for him to be in, that was in late production of Melee, but couldn't add him so now they add him in Brawl and since the creator of Sonic loves Nintendo, Miyamoto is deciding to add his Sonic too just so he doesn't get any grudges or anything and Megaman did originate on Nintendo so there you have it; Megaman could be in it too
