Well, you might be able to get a free Charmander egg from the Breeding Center if you ask. They become Charizards like Flare once they do enough fighting.

[In fact, give him a sec, and he'll hunt down his shiny Charmander, Cinder. She blinks at the camera and latches onto her tail, shivering a little. Seems someone lacks Flare's confidence.]

As for the other Pokémon I mentioned... Hoothoot's an owl and Pidgey's your standard bird. Looks kind of like a miniature hawk.
