In anime, Ash acquires a Charmander early in the series. Ash's Charmander originally belonged to a trainer named Damian, who believed it was weak and cruelly abandoned it, telling it to stay in one spot until he "returned". The Pokémon was very loyal to its trainer and risked its life sitting in the rain, waiting for a trainer who'd never come back to it. Ash, Brock, and Misty had to rush it to a Pokémon Center to keep it alive. Upon seeing Damian's true colors, Charmander joined Ash. It was immediately one of Ash's most used Pokémon, defeating such opponents as Koga's Golbat, Erika's Weepinbell, and helped capture Ash's Primeape. Charmander evolved into Charmeleon after a battle against an army of Exeggutor. His personality changed drastically, disobeying Ash and fighting only when and how he pleased.
