===Pokémon Diamond and Pearl Adventure!===
The Pokémon League first appeared in A New Battle Begins!, where the League tournament started. In Mitsumi's first match, she went up against Cynthia. Despite faring well against her, however, Mitsumi suddenly forfeited, deciding that the competition would be more interesting that way. In Hareta's Heart's Desire, was defeated by Koya, while Hareta managed to overwhelm Flint to such a degree with his that the Elite Four member chose to forfeit, admitting that his Pokémon stood no chance against the power of a Legendary Pokémon.
In Hearts and Spirits Collide, during the battle between Hareta and Koya, Hareta's long-absent father, Kaisei, was revealed to be in the audience, watching his son's battle. In A Surprise Visit from Hareta's Father!, Hareta and Koya's battle was interrupted when multiple s working for Charon appeared, intending to blow up the League stadium with a powerful bomb. However, thanks to Hareta and the other s present, the explosion was contained so that it didn't cause any damage. Kaisei then briefly met with his son, giving him a Pokémon Egg before leaving.
In Mitsumi's Wish, Mitsumi and Cynthia had a talk following the Team Galactic attack, and decided to have a rematch after Mitsumi proclaimed that she'd use her full power to defeat Cynthia.
In Gathering of the Legendary Pokémon!, the aborted Pokémon League tournament was resumed, although its conclusion was not shown.
