Smart Bomb

The Smart Bomb is an item from the Star Fox franchise. In the Super Smash Bros. series, it is also an item in every title starting with Super Smash Bros. Brawl. When a Smart Bomb is thrown or attacked, it explodes on the spot, constantly dealing damage to any fighters caught within the expanding explosion and then dealing knockback upon disappearing. Unlike the Star Fox franchise, the Smart Bomb does not have any homing abilities.

On occasion, the Smart Bomb fails to explode, indicating by their distinct sound and failure to detonate, and it remains on the ground until exploding unexpectedly. A fighter can still pick up a failed Smart Bomb, which does not detonate while it is being held. However, if a set amount of time passes, the Smart Bomb explodes as soon as it is thrown. In Super Smash Bros. for Nintendo 3DS / Wii U, a Smart Bomb always explodes the second time it is thrown, unlike the failed Smart Bombs in Super Smash Bros. Brawl, where it explodes only after a set amount of time or upon being attacked. Some Smart Bombs only explode once they hit the ground, which is occasionally shown when they are thrown upward, as regular Smart Bombs are thrown a set distance depending on the might of the throw before exploding.
