It is possible to capture a Cresselia in Pokémon Legends: Arceus. Initially making its debut in Pokémon Diamond and Pearl, Cresselia is the second half of the Lunar Duo from the Sinnoh region.

Since Pokémon Legends: Arceus takes place in an ancient version of the Sinnoh region, every legendary from there is present.
