Ash's Charizard

Ash's Charizard is a Pokémon owned by the character Ash Ketchum, used throughout the Pokémon Anime series. Initially, Charizard was caught as a Charmander in the episode Charmander the Stray Pokémon, being Ash's fifth Pokémon. It is currently training at Charicific Valley. Ash and Brock had taken care of it when Charmander's original trainer had abandoned it in the rain, deeming it as a pathetic and weak Pokémon. After bonding with both of the trainers, it ultimately chooses Ash as its new trainer.As it prepared to leave with Ash, its original trainer had wished to reclaim and recapture it, only to have Charmander use Flamethrower on its former trainer. When Charmander evolves into a Charmeleon, it refuses to obey Ash's order. Similar, when it evolves into a Charizard, it disobeys Ash too. It simply shot out flames onto Ash's face. After Ash saved it.

An injury it received from a Poliwrath's Ice Beam, Charizard starts to obey Ash, and sometimes it will burn Ash's face out of affection. When Charizard entered the Charicific Valley, it immediately challenged one of the many Charizards that were there, only to be humiliated at its loss. Ash gives Charizard the option to stay and train if it wishes to, which Charizard agrees and was given an assurance from Ash that it won't be abandoned. Ash didn't want to leave Charizard but he knew it was for the best for Charizard.

It appeared in the series "The Symbol Life", where Ash used Charizard to battle with Noland's Articuno. Charizard won Ash the Knowledge Symbol before it returned to the Charicific Valley.
