Steve first appeared when he challenged Emile to a Pokémon battle. He sent out his Aron against Teddy, Emile's Vigoroth, but then Emile withdrew Teddy. Emile then sent out Kappa, his Lombre, who defeated Aron with ease.
Steve called Emile to request a rematch.
Steve was ready for a rematch, his Aron having evolved into a Lairon. Chugga's Moegami made short work of him, and Steve took his defeat gracefully. Chugga and Steve parted amicably.
"Ufufufufufu... Want to battle against my Pokémon?"
"Don't forget what you've done to me! I'll make it so you can't forget!"
"Emile? Steve here. My Aron is a force! It won me another battle just now! I can't wait to have a rematch with you."
- If you rematch Steve enough, his Aron will eventually evolve into a Lairon and later into an Aggron.
- There's another PokéManiac named Steve in Pokémon FireRed and LeafGreen. It's unclear whether or not they're the same person.
