Charizard is a draconic, bipedal Pokémon. It is primarily orange with a cream underside from the chest to the tip of its tail, which burns with a sizable flame. Charizard has a long neck, small blue eyes, raised nostrils, and two horn-like structures protruding from the back of its rectangular head. There are two fangs visible in the upper jaw when its mouth is closed. Two large wings with blue-green undersides sprout from its back, and a horn-like appendage juts out from the third joint of each wing, which is also the point from which a single wing finger passing through the wing's membrane stems. Charizard's arms are short and skinny compared to its robust belly, and each limb has three white claws. It has stocky legs and a single cream-colored walking pad under each of its plantigrade feet.
Both Mega Evolved forms feature a shorter snout and white vertical slit pupils, with the bright underside reaching the lower jaw.
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 walking pads. 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 lower trims of its wings are divided into large, rounded points, and each third joint 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 with increased heat.
As Mega Charizard Y, it becomes more sleek and expansive in appearance but retains its normal coloration. It has three pointed horns on the back of its head, the middle of which is longer. Its snout has larger fangs and a ridge on the nose. Its neck is shorter but its torso is thinner and longer. It features longer digitigrade feet devoid of walking pads. Its hands are less developed, with extremely shortened fingers that are no longer separated each from the others. Small wings develop on its wrists, while the ones on its back become larger, lose the wing finger passing through their membrane and end up with ragged edges. The back of its tail has a large thorn at the base and three smaller ones near the tip, which now burns with a longer flame. Mega Charizard Y is said to have incredible flying prowess, being able to reach incredible heights.
This Pokémon flies in search of powerful opponents to battle, and its fire will burn hotter as it gains experience. Its fiery breath is capable of melting boulders, massive glaciers, and has been known to accidentally cause forest fires. In the past, Blast Burn was its signature move. Charizard typically inhabit mountains and valleys. The anime has shown that only a weak Charizard would show off its power and that a group of Charizard resides in the Charicific Valley in Johto. It also showed that Charizard is able to swim underwater, with Pokémon Origins further showing that the flame on the tip of the tail can still keep burning underwater.
A Charizard appeared in Mewtwo Strikes Back, where it participated in the battle between the original Pokémon and the cloned Pokémon, battling Ash's Charizard and winning easily. Unlike much of its brethren, Charizard wasn't cloned from Ash's Charizard and it had the same marks that Charmandertwo had, indicating that it was likely obtained by Mewtwo through different means than the ones used to clone the Trainers' captured Pokémon. Charizard reappeared in Mewtwo Returns.

One of Blue's main Pokémon, Charizard, debuted as a Charmander. With his increased capacity for battle both with augmented strength and his flight ability, he proved to be a valuable asset for Blue, both during the Silph Co. battles and in the Pokémon League, where Red's Venusaur narrowly defeated him. He had evolved from Charmeleon sometime before Kalling Kadabra. In the X & Y chapter, he has obtained a Charizardite Y, with it he can Mega Evolve into Mega Charizard Y.

Charizard's first-released TCG card, which as part of the Base Set, was widely regarded at the height of popularity of Pokémon as the best card ever. This was because of its powerful attack, Fire Spin, and useful Pokémon Power, Energy Burn, which allowed it to convert any Energy attached to it to Fire Energy. Fire Spin needed four Fire Energy and could deal 100 damage, knocking out the majority of Pokémon cards. In addition, it had the highest HP then, at 120. Individual Charizard cards were sold up to as much as $150. First edition cards of this dwarfed this price at one point breaking the $1000 US price point. This Charizard card was reprinted in Wizards of the Coast's Base Set 2 and Legendary Collection sets, and released again with updated artwork in the Stormfront expansion.

Charizard resembles stereotypical European dragons, which are heavily associated with the element of fire in Western folklore; this draconic appearance would later be reflected in the Fire/Dragon typing of Mega Charizard X. Considering the Japanese and English nomenclature, Charizard's draconic design may be a reference to how various types of lizards are named after dragons, most notably Komodo dragons and flying dragons – two categories of lizards with which Charizard shares loose physical similarities.
