Flare Blitz

Flare Blitz is Charizard's side special move in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, taking the place of Rock Smash from Super Smash Bros. Brawl. It originates from the Pokémon franchise, in which it is a Fire-type move.

Upon using the move, Charizard flies directly ahead, covering itself in fire, and is knocked back slightly when it hits anything. Charizard is also dealt recoil damage throughout the entire attack. The attack's range is quite long, but Charizard does risk self-destructing itself if it goes off-stage while using it.

On a side note, whenever Flare Blitz activates a fighter's Counter, the counterattack only takes into account the hit before the explosion.

Variants
This move has two unlockable variants in Super Smash Bros. for Nintendo 3DS / Wii U:

The first is Blast Burn, another move from the Pokémon franchise, which is slower and does not travel very far, but ends with a larger explosion that deals more damage, both to the opponent, and Charizard.

The second is Dragon Rush, a Dragon-type move from the Pokémon series, which is less powerful, has a shorter travel distance, and does not have the fire effects. To make up for those drawbacks, however, the attack delivers multiple hits to opponents, and it does not damage Charizard. Lastly, Charizard does not get knocked back if it hits anyone while using the attack, and its shorter travel distance reduces the risk of self-destruction, making the move more effective for recovery than the other Flare Blitz variations. Mega Charizard X can also perform this attack.
