A Hogwarts Elf Professor

As a time traveler, Agares decided to stay away from Hogwarts after graduating, fearing he'd be caught up in the dangerous situation. However, his thoughts changed after he struck a deal with Arceus, the Pokémon God. Chosen by Arceus as a Pokémon ambassador, Agares decided to start promoting Pokémon among the more receptive wizarding community. Five years after graduation, Agares returned to the magic school, this time as a professor.
