Mario's fireball is an example of a projectile

A projectile is an object or other attack that moves 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.

Most projectiles can be easily identified by attacking a metal box: if the character becomes metal, then the move is not a projectile.

Number of Projectiles per Character

This table includes all non-Final Smash projectiles for every character, as well as some important properties of each.

Character Projectiles Reflectable Absorbable Unique/Special Properties
Bowser Fire Breath     Size and length decreases as Bowser continues to breathe, releasing the move slowly recharges it.
Captain Falcon None.
Diddy Kong Peanut Popgun     Can be charged, which increases damage and speed while flattening the movement angle, but charging too much causes the move to fail. Can be grabbed and subsequently thrown as an item.
Banana Peel     Produces a banana peel.
Rocketbarrel Boost (when the barrels come off)     Has a random trajectory. Cannot be shielded.
Donkey Kong None.
Dr. Mario Megavitamins     Affected by gravity, bounces on the ground.

Blizzard     Can freeze opponents.
Ike None.
