Charizard is a draconic, bipedal Pokémon. It is primarily orange with a cream underside from the chest to the tip of its tail. It has a long neck, small blue eyes, slightly raised nostrils, and two horn-like structures protruding from the back of its rectangular head. Two fangs are visible in its 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 top of the third joint of each wing. A single wing finger is visible through the center of each wing membrane. Charizard's arms are short and skinny compared to its robust belly, and each limb has three white claws. In Pokémon Red and Green, Charizard is seemingly shown holding a fireball, implying that it's capable of manipulating its flames using its hands; this is seen in media where it uses Fire Punch. It has stocky legs with cream-colored soles on each of its plantigrade feet. The tip of its long, tapering tail burns with a sizable flame, which can intensify to a blue flame if Charizard is irritated.

Charizard typically inhabits mountains and valleys, such as the Charicific Valley in Johto. However, Charizard can also live in volcanoes, forming packs with other members of its family, including Charmander. In Pokémon Snap, it's shown that Charizard are fully capable of living inside lava within volcanic craters.

Charizard flies in search of powerful opponents to battle, and its fire will burn hotter as it gains experience. Its fiery breath can melt boulders and massive glaciers and has been known to cause forest fires accidentally. Though its fiery breath is hot, it never turns it on any opponent weaker than itself. The Pokémon the Series: Gold and Silver episode Charizard's Burning Ambitions (EP136) showed that only a weak Charizard would show off its power. The side story episode Those Darn Electabuzz! (HS15) showed that Charizard can swim underwater, with Pokémon Origins further showing that the flame on the tip of the tail can still keep burning underwater. Charizard's wings can carry it to an altitude of 4,600 feet (1,400 meters), but An Illustrated Book of POCKET MONSTERS notes that its droppings were found on Mt. Fuji, implying it could fly thrice as high. In Pokémon Sleep, as well as media like the animated series, Charizard is known to sleep in an incredibly relaxed position, as it is very confident in its power. It has three different sleep styles: Stomach Sleep (also used for Atop-Belly Sleep), Tummy-Rub Sleep, and Tummy-Up Sleep - the last of which has Charizard sleeping flat on its back, which may be an indicator of that Charizard being especially strong. In the animated series, it was shown that Charizard may be vulnerable to their tail flame going out in the same way as Charmander, according to the Pokémon the Series: The Beginning episode Charizard Chills (EP107), where Ash warns his Charizard to not let its flame go out.
