Charizard

Charizard is a dual/type Fire-Flying Pokemon. It is the final form of Charmander. It can Mega-Evolve depending on game. In Pokemon X, Charizard becomes Fire-Dragon when Mega-Evolved. In Pokemon Y, Charizard remains Fire/Flying.

Physiology
Charizard is a large dragon-like Pokémon that differs greatly from its pre-evolved form. The red skin color of Charmeleon is no longer apparent, as Charizard appears to have reverted to the orange/yellow color of Charmander. The single horn that was on the back of its head is now two, one on either side. The most notable difference between Charizard and its pre-evolved forms are the large wings that have developed on its back, which give Charizard the capability of flying.

Charizard's Mega Evolution using Charizardite X is different from Charizard, as it now has gray body color and blue flames, while using Charizardite Y Mega Charizard has a big horn on the top of its head and larger wings.

Other Appearances
Charizard appeared as a playable character in Super Smash Bros. Brawl. It is one of the three Pokemon that the Pokemon Trainer uses in the game, the others being Squirtle and Ivysaur. It returns in Super Smash Bros. for Wii U & 3DS as a standalone fighter, due to the removal of character transformations.

Trivia
