Charizard emits a blue glow at startup, and then cloaks itself in flames and rushes forward, hitting anyone in its path. Flare Blitz is a particularly strong attack with high knockback but has a very slow startup, making the move easy to punish. It has recoil damage both in the beginning and when Charizard hits something, like an opponent, a wall, or certain projectiles. Charizard takes 5% damage when the move is used and another 5% when it collides. It then falls over (this cannot be teched), allowing the opponent to punish Charizard extremely hard if they blocked the attack.
The attack inflicts 4% to the opponent from the collision and another 15% from the explosion. Rarely, the explosion may miss the opponent, dealing only 4% and low knockback but causing Charizard to receive full recoil. This happens most often when the opponent is above Charizard. 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. The 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.
Flare Blitz can be used for horizontal recovery, as it travels the whole length of Final Destination and can snap the ledge before the animation completes.
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. It is 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.
