Character: charla
Charla (Japanese: リサ Lisa) is a Charizard belonging to Liza who lives in the Charicific Valley.
Charla belongs to Liza, who maintains the Valley. When Ash and his friends were going through the Valley, they had the opportunity to meet Charla. Charla is Liza's only Pokémon, and her greatest partner, seeing as she travels with her to places outside the valley. Charla was also the only non-wild Pokémon in the valley when Ash and his friends met her.
Charla was considered to be Liza's most trusted Pokémon out of the other Charizard in the Charicific Valley. During her debut episode, Charla had very little trouble in showing her flying skills in contrast to Ash's Charizard when they first arrived in the Valley. Charla started to bond with Ash's Charizard during its stay at the Valley.
In Great Bowls of Fire!, it was revealed that Ash's Charizard became Charla's bodyguard and that Charla has apparently fallen for it.
