The X Bomb is an item introduced in Kid Icarus: Uprising. It explodes shortly after being thrown, releasing four large quick and strong projectiles that spread out in an X-shaped fashion, hence the name. The projectiles can pierce through multiple enemies and even change directions if it hits a wall, making the X Bomb excellent in narrow areas. The directions of which the X Bomb explodes depends on the direction it's facing once it hits the ground.
X Bombs explode shortly after being thrown, ripping through multiple enemies for massive damage with their cross-shaped blast. The orientation of the explosion depends on the direction faced when the bomb is thrown.

This bomb will explode shortly after it leaves your hand, expanding outward in an X-shaped blast that tears through anything in its path. Its incredible power can be a lot of fun, but don't get crazy. Blowing up everything is no way to get ahead in life!
