"Yo Trainer! You had me counting the days on my fingers waiting for you to come. I heard from Volkner what you did in Sunyshore. You managed to light a fire in that guy's heart again. How could you not expect me to look forward to seeing you in battle? You're facing a Fire-type Pokémon user with me. Let Flint see how hot your spirit burns!"
Flint first appeared in Flint Sparks the Fire, where he was visiting his friend Volkner, who had become surly due to the lack of worthy opponents. Flint also met Ash Ketchum and his friends and battled Ash in the hopes of reigniting Volker's fighting spirit. Although his Infernape easily defeated Ash's Buizel and Infernape, Pikachu held its own against Infernape long enough to impress both Flint and Volkner. After the battle, Volkner agreed to battle Ash.
Flint also battled against the Olivine City Gym Leader Jasmine, whom he defeated easily.
Flint later appeared on television where his Infernape battled Cynthia's Garchomp. Flint was defeated by Cynthia but his Infernape was mentioned to have beaten two of Cynthia's Pokemon and held its own against Garchomp.
