The Cracker Launcher (クラッカーランチャー, Cracker Launcher) is a shooting item that allows the user to rapidly launch firecrackers, which bounce off walls and explode on impact with a floor or enemy. The character using it can aim the launcher at different angles by tilting the control stick up or down. It is also possible to move forwards and backwards, while turning around is done by tapping the control stick sideways. It could be said to be the shooting equivalent of the Hammer, as it is the single most powerful weapon of its type, but it can still be reflected. It is also like the Hammer in that, while holding it, a character is limited to a single jump and no other attacks (aside from dropping or throwing it). Cracker Launchers will be dropped if the holder flinches, even slightly. When used near a wall, the character will lose the launcher and take damage with strong knockback.
Aiming the Cracker Launcher can be hard to do and turning can be a hassle, but it can easily be used to take out large groups of enemies. Each Launcher can fire 16 shots before running out. The blast radius makes it easy to damage others, but the shots themselves can be difficult to get the first hit with. The last shot is distinguished by a grey trail of smoke, a different shooting noise, and is more powerful than the rest.
When CPU players use a Cracker Launcher, they usually shoot all of the fireworks at once while aiming up and down. This makes CPUs very lethal, as doing this makes the fireworks hard to dodge. However, should it rebound, it will deal damage to the user if it makes contact with them.
Interestingly, the longer the character has held the Cracker Launcher for, the farther the shots will go. The shot speed reaches its cap after around 4 seconds. Dropping the Cracker Launcher and re-grabbing it will not reset this time, even if another player grabs it.
In Brawl, the momentum of a projectile will affect the damage a character will receive; these are recorded in bounces.
