1. That's kind of what I meant. But Lati@s is not from the main part of the game. When you say "main part", you mean Mascot Legendaries, right? Examples include Lugia, Rayquaza, Mewtwo (sort of, as it wasn't a "mascot", because in gen 1, the starters were), Zekrom, Palkia, ect. Some Event Legendaries include Jarachi, Celebi (who can also be considered the Crystal Mascot), Genesect, Mew (sort of, as there weren't really gen 1 "events" that I know of), Darkri, Diance, ect. Arceus doesn't quite fall into Mascot or Event, but obviously it's a no. Event Legendaries are legendaries only obtained legally via non-in-game-events. Battle Facilities (Frontier, PWT, Mansion, ect) ban Mascot and Event legendaries. VGC, for some reason, bans all of those and Chaterot.
