>>13952737Mythical archetypes (The Nintendo term; event-only, banned at Battle Tower/Frontier/Subway AND Nintendo official tourneys, even in cases where the banned legends were allowed)
Introduced in Gen 1:
Balanced: 600 BST, all stats equal, usually part-psychic. Design quite consistent and pixie-like. Mew, Celebi, Jirachi, Manaphy (not psychic!), Victini. Shaymin in its debut qualifies except for the design (and the lack of psychic type), but the introduction of the Sky forme deviates it from the archetype; its oddity and the fact that it is an archetype repeated within a gen is reminiscent of the Kami trio.
Introduced in Gen 2:
Nothing, apart of starting the divergence between Mewtwo and Mew.
Introduced in Gen 3:
Final: 600 BST, quite specialiced stats with some sort of control in terms of form change, rather large movepool, design in stark contrast with the Balanced myths, at the end of the Nat Dex in their debut. Deoxys and Genesect; Arceus could've counted, but it is more of an unique case.
Introduced in Gen 4:
Related to a Legend: Has the expected BST and level-up learnset to be considered the counterpart of another legend, but is event-only. Darkrai (if it was a regular legend it'd make a cookie-cutter due with Cresselia and would have turned what Latias/Latios started into a pattern), Keldeo (fourth member of the musketeer trio, like its inspiration). Mew doesn't count because, in spite of its heavy lore relationship with Mewtwo, it is unrelated stat- and role-wise.
Arceus: Quite likely unrepeatable, a notch above any other mythical or legendary Pokemon; 720 BST, all stats equal, highly versatile. Takes elements of plenty of archetypes and surpasses them.
Introduced in Gen 5:
Misc Mythical: 600 BST, basically a mythical that doesn't fit with any archetype so far. Meloetta.
