A projectile is an attack or other object that operates independently of the character that used it. Common examples of projectiles include the Charge Shot, Blaster shots, and thrown items. Most projectiles can be reflected, while others can also be absorbed.
A majority of characters have at least one projectile attack, while some have two or even three. It is considered a disadvantage to lack a projectile, as they can be very useful in both approaching and camping out opponents' approaches. Projectiles also cause the target to take hitlag while the user does not, which allows a few free frames of action.
As projectiles are (in general) considered indirect attacks, the vast majority of enemies in the Subspace Emissary resist them outside of any weak points they may have - in fact, only Porky, Meta Ridley, and Tabuu do not. Projectiles are also generally special moves executed with the B button, but since Brawl, some characters such as Snake, the Villager, and Mega Man have standard attacks that are projectiles.
Projectiles used by characters
