Giovanni is a major villain in the Pokémon series. In the Kanto adventures, he is the final Gym Leader and the head of Team Rocket, a sinister organization. In the Johto adventures, though he has reformed, a new division of Team Rocket seeks him to have him lead them again. Giovanni, however, is proved to be evil in Fantendo Collision in which he collides the universes together while keeping Ash Ketchum hostage.
