Here are all the possible Legendary Pokémon that you can encounter at the end of a Dynamax Adventure.

Similar to past games, you may only catch one of a particular Legendary Pokémon. After catching this Pokémon, you can encounter it again, but it will disappear after defeating it. Also, you may catch a Legendary and choose not to keep it–in this scenario, you can encounter and catch it again (useful for shiny-hunting).

Should you reach a Legendary Pokémon but either fail to defeat it or choose not to keep it, the scientist at the front will let you save a path to the Legendary, for future adventures. This will guarantee the Legendary at the end. Up to 3 paths can be saved. Peonia also offers random paths after each adventure, in exchange for 5 Dynite Ore.
