Mega Charizard X is a dual-type Fire/Dragon Pokémon.
As Mega Charizard X, its body and legs are more physically fit, though its arms remain thin. Its skin turns black with a sky-blue underside and soles. Two spikes with blue tips curve upward from the front and back of each shoulder, while the tips of its horns sharpen, turn blue, and curve slightly upward. Its brow and claws are larger, and its eyes are now red. It has two small, fin-like spikes under each horn and two more down its lower neck. The finger disappears from the wing membrane, and the lower edges are divided into large, rounded points. The third joint of each wing-arm is adorned with a claw-like spike. Mega Charizard X breathes blue flames out the sides of its mouth, and the flame on its tail now burns blue. It is said that its new power turns it black and creates more intense flames.
