Marty the Sneasel and Tony the Weaville. Two Mystery Dungeon OCs. The two are brothers, with Tony being older than Marty.

Tony went to the pokemon world first, where he joined a guild and evolved. He considers the Pokémon world to be his real home and doesn't want to leave.

3-4 years after Tony went missing, Marty entered the Pokémon world as well, and he managed to find his missing older brother, who was a Pokémon the whole time.
