"Ridley should be dead"That just sounds like an AT promotion with an extra step. Effectively, it's the same; A fighter and an NPC version of them existing at the same time in the same place. Sure, there's multiple Pokemon in canon, but if we're going off of canon Samus and ZSS shouldn't be separate, Ridley should be dead, Dark Samus should be dead, and Sephiroth should probably be dead (Though, I think he can just revive himself because Lifestream or something like that).
