Charla (Japanese: リサ Lisa) is a Charizard who lives in the Charicific Valley. She is voiced by 愛河里花子 Rikako Aikawa in both Japanese and English.
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 it travels with her to places outside the valley. Charla was also the only non-wild Pokémon in the valley when Ash and co. met her.
In Great Bowls of Fire, it was revealed that Ash's Charizard became Charla's bodyguard and it's apparent that Charla has fallen for it.
