In Memories Are Made of Bliss!, Ash and his friends watched her battle with Flint for the title of Champion.

Ash's Charizard's best feats are defeating Magmar, Electabuzz and Poliwrath with horrible relations, sweeping half of Gary's Silver Conference team while having disadvantage to 2 of Gary's mons, took out an Articuno, and almost beat the Shinx out of Iris's Dragonite.
