Ash and his friends ran into Maya and while her Chimecho battled McCann's Scizor. The battle ended with McCann's victory. Her cheery nature softened McCann's hardened stance against all Trainers who he viewed as unworthy of his training. With little effort, she convinced her grandfather to have a battle with Ash and have a rematch the following day. As Ash and his friends left Ash's Gliscor in their hands, she reassured him that it would be looked after.
Chimecho is Maya's only known Pokémon. Like her grandfather's Scizor, Maya's Chimecho also used winds to fly and was used by Maya against her grandfather in battle. Although Chimecho was powerful, it was unable to stand up to Scizor's skill in the air and was defeated, accidentally knocking Piplup out in the process.
