Bomb

Bombs are the basic weapons for Samus Aran's Morph Ball. Bombs can break certain objects, and are essential to defeat many bosses such as Spider Guardian and Amorbis, although they are not very effective on normal enemies. Bombs can damage enemies within a certain range. If Samus deploys a Bomb below her, she'll make a small jump, called a Bomb Jump. In 2D Metroid games, Samus can drop multiple bombs with proper timing to perform an infinite bomb jump that propels her through the air. Bombs can activate Bomb Slots, which in turn activate another object, as well as destroying Bomb Blocks in the 2D Games, Sandstone in Metroid Prime and Talloric Alloy throughout the Prime series. A more powerful Bomb called the Power Bomb is also available. In the Prime Trilogy as well as in Metroid Prime Hunters Samus can only use 3 bombs in a short amount of time, and the bombs must recharge before being used again.

Bombs have appeared in every Metroid game.

In the 2D Metroid games, bombs appear as actual metal bombs, which flash until detonation. It is also possible to lay several bombs instead of the three at a time as in the Prime games. In Super Metroid, Samus can use the Charge Beam to perform special bomb combinations by charging the beam and then entering morph ball form, such as laying five bouncing bombs instantly. During the Prime Trilogy, bombs appear as a blue energy ball when dropped. When they detonate, they are surrounded by blue light. In the first two Prime games, they are used to do bomb jumps to small tunnels and to damage enemies. In Corruption, they still serve the same purpose, but a small flick upwards of the Wii Remote activates the Spring Ball to be used as a faster alternative for reaching areas in Morph Ball form. The Spring Ball also appears in the New Play Control! Prime titles.

Trivia

 * It is unknown how Samus generates these bombs, or how the energy stays in a sphere shape until detonation.
