Professor Telesu (Japanese: テレス博士 Dr. Telesu) is a character of the day in the Pokémon anime.
Prof. Telesu appeared in A Crowning Achievement. He is an archaeologist who was studying hieroglyphics near a lake full of Slowpoke that suffered a drought after an earthquake. According to the hieroglyphics, a Slowpoke needed to evolve into a Slowking to save the colony, but the Shellder in the lake kept on latching on to the Slowpoke and causing them to evolve into Slowbro. His daughter's Slowpoke was able to make it, and was intelligent enough to lead the Slowpoke and Slowbro into an underground cave where water was plentiful.
