Earl Dervish/Manga/PM

Earl makes an appearance in Demanding Tests at the Pokémon School! of Pokémon Pocket Monsters.

When the students recommended to go to the Pokémon academy, Earl greeted him and his Pokémon when they were about to go in. He then explained some of the basics and motivated Red in going. Red agrees to go to the school and Earl teaches a class, with Red as one of his students. He gave out a test. After the test, Earl called down Red to see him after class since he and his Pokémon failed.

Earl was revealed to have imprisoned some Pokémon and then went down a hallway to another room. In the room, Earl shows Red to one of his bright students who ends up battling him. After the battle, Earl and the student was shocked to see that flunking student defeated someone smart. Earl and the student decided that due to Clefairy's skills, he should teach a class. However, this turned out to be false when the students that Clefairy was teaching were giving him a hard time.
