The Pokémon League entrance exam instructor was the instructor for the Pokémon League Admissions Exam, an exam where people are allowed to get access into the Pokémon League without earning Gym Badges.

The instructor then took them to the final test: a Pokémon battle with him using his Pokémon. James sent Ivysaur and Charizard at the same time, which caused him to be expelled on the spot.

Team Rocket's Meowth then interrupted the match after Meowth was frozen by Vaporeon's Ice Beam.
