Legendary and event Pokemon
Every legendary and mythical Pokemon of the four games can be caught in Platinum Emerald itself, with no events or trades. The mythicals that needed a real event wait in their event places, opened by a key item you are given after the right Champion.
The levels on this page are base levels, scaled to your progress: your first region keeps its own game's levels, and each region you open after it is scaled to how many regions you have finished (see Levels). Celebi's level 30, for example, can be 76 in a late game.
