Remember back in the first generation when you were sure Dragonite was a legendary? Or in the second generation whenyou tried to convince your buddies that Tyranitar was up there with Ho-Oh and Lugia? Well, you were wrong, along with myself. However, these two and many others are in the category, Pseudo-Legendaries. Pseudo-Legendaries are, according to Bulbapedia, defined as " ...any Pokémon that has a three-stage evolution line, two types, has 1,250,000 Exp. at Level 100, as well as a base stat total of 600. Pseudo-legendary Pokémon are often more powerful than other non-legendary Pokémon, possibly due to their high base stats. All pseudo-legendary Pokémon have Attack or Special Attack as their highest stat."
Discussions here will include the pseudo-legendaries themselves, legandaries that should be demoted to pseudo, regular pokemon that should be promoted to pseudo, and anything related to those topics.
