The metroids weren't villians, Mega. They were an unknowing specie being manipulated by the space pirates. They attack everyone and everything, but it's out of instinct, not evil intentions. I don't know what you mean by "the Machine", Bass is a Capcom character, so he won't be appearing on the N64, and no one would even remember the Eggplant Wizard except for a few fans.
