In the GamesEdit
Charmander is a starter Pokemon in Pokemon Blue and Red, FireRed and LeafGreen. Charmander can be picked by the player in HeartGold and SoulSilver.
In the Anime, Charmander was one of the three Pokemon Ash Ketchum tried to choose as his first Pokemon but someone had picked Charmander.
In the episode "Charmander the stray Pokemon" Ash and his friends find a stray Charmander abandoned by its owner Damien. This Charmander eventually comes over to Ash's side and would later evolve many episodes later.
Another Charmander nicknamed "Zippo" would appear later under the care of Ritchie.
