Charizard (Mega X)

It's Mega Charizard X that really steals the show, here. A fire/dragon type with blue flames perpetually pouring from its mouth, black instead of orange skin and devilish shoulder horns, it has more of an "evil" dragon vibe to it, like Maleficent's transformation in Sleeping Beauty, and pretty much as cool as an otherwise by-the-numbers anime dragon is going to get.

I guess it's also pretty interesting that Mega-X doesn't flap its wings like its two siblings, but just sort of soars like a vulture. Spooky!
