Charizard steps back and shoots a stream of flames from its mouth, which can be directed up or down by tilting the control stick in a particular direction. The flames die down the longer the button is held, but they will never stop; however, they will become extremely small. This attack is very similar to to Bowser's Fire Breath, though the flames are smaller and have longer range, while having slightly faster startup. It is Charizard's only special in SSB4 that lacks armor.
Similar to Bowser's Fire Breath, Flamethrower is generally used to reset a neutral game, though the longer range also makes it superior as an edgeguarding tool for targeting poor recoveries such as Ganondorf's Dark Dive. While poor in Brawl due to the powerful SDI mechanics, Smash 4 and Ultimate have decreased its SDI multiplier and weakened the mechanic, making it far more acceptable. Additionally, Charizard no longer steps back in these games, making it easier to land the clean hit through increased range to rack up more damage.
As Charizard's down throw
Charizard also uses Flamethrower in its down throw: Charizard throws its opponent to the ground, and then burns them with Flamethrower. It has mainly horizontal knockback, and it cannot be reflected, even by a Franklin Badge.
In SSB4, prior to patch 1.0.8, down throw could KO at higher levels of damage, but could be DI'd out of. Following the patch, however, it is now a combo throw, following up into a forward aerial until around 60%, and Charizard's up throw is now its KO throw. This inflicts a total of 6% damage. This change persists in Ultimate, now comboing into Charizard's notoriously powerful back aerial.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
As Charizard's attack as a Poké Ball
Originally, Charizard used Flamethrower when appearing from a Poké Ball in Super Smash Bros. and Super Smash Bros. Melee. Charizard alternates between breathing fire to the left, then right. It deals extremely high knockback and has a hitbox on its body as well as the fire, KOing characters at very low percentages.
Use by other Pokémon
There are also Pokémon other than Charizard that have used Flamethrower within the Smash series:
Flamethrower is a special Fire-type attack introduced in Generation I, with high power and a small chance to burn the opponent. It involves the user shooting a stream of fire, usually from its mouth, at the opponent. Charizard originally learned the move at level 46 in Pokémon Red and Green and has learned it naturally ever since. Along with Thunderbolt and Ice Beam, it's one of the original "strong and accurate" attacks in the series, dealing among the most damage on average for its type.
Fire Fang, one of this move's custom variations, is a physical Fire-type attack introduced in Generation IV. It involves the user biting the opponent with fiery fangs and, while not very powerful, it has a small chance to burn the opponent and/or make it flinch. It is boosted by abilities like Strong Jaw and Tough Claws, the latter of which Mega Charizard X gains upon Mega Evolving. Charizard has been able to learn Fire Fang since its introduction at level 28 as a Charmeleon.
