Firework

Firework is an original item introduced in Super Smash Flash 2, revealed on 2016 New Year's Eve.

Overview
The Firework is a red and yellow-striped rocket-shaped, projectile that travels a short distance after being thrown, dealing 7% damage to any opponent on its way, proceeding to explode afterwards and dividing into nine Fireworks that perform a big circling motion also explode shortly after. In certain cases, this item is a capable of dealing about 80% of damage, making it one of the most damaging items in the game, if the character happens to be hit by most of the explosions. Any damaging hitbox is capable of igniting a Firework. Normally, the thrower is safe from the explosions even if he/she directly comes in contact with them, however, if the thrower instead attacks the Firework, it will raise into the air and damaging the character in the same way as if it was normally thrown.

Initially, the Firework was supposed to not explode on contact with opponents, instead exploding only when it hits a wall, or, like in the currently implementation, after a while passes, dividing itself in nine and exploding afterwards.

Trivia

 * Firework is the first original item to be included in Super Smash Flash 2 and in the overall Super Smash Flash series.
