Gaster The Alolan Raticate

Gatser (not to be confused with Gaster the Icigool) is an Alolan Raticate from Old Roria. He is friends with the pokemon in the Dream Wastes, and has been to pokemon jail a few times. He supposedly died when the world was deleted, but is currently in a pre-reincarnate like state where he is in a dark void, and can hear echoes of the overworld. Flygon, Snowy, and the Bird Trio are also in this void, but they cannot see or hear eachother.
