• Japanese (TL) / Japan: Isao's Lizardo

After Mateo's Cloyster was knocked out by the Crystal Onix, Mateo's Charmeleon was sent out to battle the Crystal Onix. It used Flamethrower and Ember on it which seemed to be effective and made it super hot and knocked it out.

Mateo's Charmeleon is also Mateo's glass-making partner. They work together to make the amazing Pokémon statues out of glass that are sold in Mateo's shop. Mateo's Charmeleon uses its Flamethrower to help melt the sand they use into glass and to keep the glass molten while Mateo blows the glass.
