Charizard emits a blue glow at startup, and then cloaks itself in flames and rushes forward, hitting anyone in its path. Flare Blitz gains limited armor during the move, able to take up to 14% damage without flinching. This is a particularly strong attack with high knockback, but has very slow startup, making the move reactable. It has recoil damage both in the beginning and when Charizard hits anything, like a wall, some projectiles, or an opponent. Charizard is hurt 5% when the move is used, and is hurt another 5% when it collides with anything. It then falls over and lands on its back (this cannot be teched), allowing the opponent to punish it extremely hard if they blocked the attack.
The attack inflicts 4% to the opponent from the flames cloaking Charizard, and another 15% if the opponent is hit with the tackle, dealing heavy knockback from the tackle itself. The move's power decreases at the end of the tackle, leaving only the flames, inflicting 4% and low knockback. Since the tackle is finished, Charizard won't receive the additional 5% recoil damage. Rarely, the explosion may miss the opponent, dealing only 4% and low knockback but causing Charizard to receive full recoil. This happens more often when the opponent is above Charizard.
The move can be used as a reliable recovery in the air, as it travels the whole length of Final Destination and can snap the ledge before the animation completes. However, Charizard continues to fall while starting up the move, which can make it difficult to snap to the ledge instead of crashing into the stage. Knocking into an opponent or side of the stage will cause Charizard to be temporarily forced into its falling hurt animation, potentially self-destructing due to its lengthy animation. This significant end lag on impact also makes Flare Blitz very punishable if shielded, and if Charizard ends up lying on the ground, it can even set up a free jab lock for the opponent. As such, the move must be used sparingly and carefully, primarily as a punishing option in its own right, but also as a movement option for mix-ups and to escape potential pressure from foes.
In Ultimate, Flare Blitz is even more powerful, and the recoil from the collision cannot be jab locked.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
Flare Blitz is a physical Fire-type attack introduced in Generation IV. A very powerful move, but the user takes a third of the damage dealt to the target as recoil.
Blast Burn is the Fire-type equivalent of Hyper Beam. Unlike its Smash Bros. variation, it doesn't damage the user, nor is it a contact move, but it does leave them vulnerable for the next turn as they need to recharge.
Dragon Rush, also introduced in Generation IV, is a physical Dragon-type attack that has a small chance of flinching the target.
Charizard learns Flare Blitz by leveling up in all games since the move's introduction. Charizard has been able to learn Blast Burn from a move tutor starting in Pokémon FireRed & LeafGreen and in all games from Generation IV onwards. Finally, Charizard learns Dragon Rush as an egg move as a Charmander.
