>>16705057>Except that's wrong. Most legendaries, disregarding a few while more remain ambiguous, are canonically are the only member of their species. For example Reshiram, Zekrom, Kyurem, Cobalion, Virizion, Terrakion, Keldeo, Xerneas, Yveltal and presumably Zygarde are canonically a singular species.Except that's wrong. Multiple trainers have Cobalion, Terrakion, and Virizion in their possession at the end-game facilities, along with other trios of legendaries. Heatran, Cresselia, Regigigas, Lati@s, all owned by many trainers. Mostly veterans (to illustrate a point). It's actually the opposite of what you say. We even have Barry's father using legendaries that you yourself are able to catch in-game.
The legendaries that are banned from the end-game facilities are debatable, but Arceus is able to create a new Palkia/Dialga/Giratina in HGSS, which strikes hard against the idea of there being only one of any of those legendaries. Mew was pregnant with Mewtwo, and there's no reason for a Mew to be able to be pregnant in the first place if there aren't more out there and they don't reproduce.
Do you even play the games?
