How does Charmander breathe fire? Charmander is a small lizard-like Pokémon. It is a fire-type Pokémon, and is capable of breathing fire.



How do Charmander and its evolved forms do this? Is there any biological basis for it, and is it ever explained in canon?
I don't think our known biology can be applied to Pokemon. Blastoise has cannons, for instance, and Pikachu can shoot electricity (is not the same be able to create electricity to shock predators that attack you and actually shooting it).

I mean, we could make theories about how they can do all those things, but the designers just didn't think about it. It would be an interesting pastime, but pretty pointless, because they would be just that, theories.
