Bombs (ボム bomu) are the basic weapons for Samus Aran's Morph Ball. Bombs can break certain objects, and are essential in defeating several Bosses, such as Flaahgra and Amorbis, although they are not of great use on normal enemies. They have appeared in every Metroid game. 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 will in turn activate another object. They can also destroy Bomb Blocks in the 2D Games, Sandstone in Metroid Prime, and Talloric Alloy throughout the Prime series. A more powerful version called the Power Bomb is also available. In the Prime Trilogy and Metroid Prime Hunters Samus can only use 3 Bombs in a short amount of time, and the bombs must recharge before being used again.

In the 2D Metroid games, bombs appear as actual metal bombs which flash until detonating. Bombs tend to explode after two or three seconds, except in Metroid Fusion, where they take approximately 5 seconds (this makes it impossible to perform repeated Bomb Jumps midair, and was likely done to prevent Sequence Breaking). It is also possible to lay several bombs instead of the three at a time in the Prime games. In Super Metroid and Metroid Other M Samus can use the Charge Beam to perform the Five-Bomb Drop by charging the beam and then entering Morph Ball form.

During the Prime Trilogy, bombs appear as a blue energy ball when dropped. When they detonate, they are surrounded by blue light. Other M's bombs appear as metal capsules that explode into the same blue light. In the first two Prime games, they are used to do Bomb Jumps in small tunnels and to damage enemies. In Echoes, there is also a mini-boss called the Bomb Guardian which steals the Bomb upgrade from Samus and can consequently produce Bombs of its own that are identical to Samus's. However, the Bomb Guardian appears to be able to produce many Bombs simultaneously, while Samus is limited to three. In Corruption, Bombs still serve the same purpose, but a small flick upwards of the Wii Remote activates the Spring Ball, which can 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 and the Metroid Prime Trilogy.

Super Smash Bros. seriesEdit

In the Super Smash Bros. series, the Bomb is Samus' down special attack and is apparently made of metal like in the 2D games. In Super Smash Bros. for Nintendo 3DS and Wii U, the move can be customized. Its two variants include the Slip Bomb and Mega Bomb:

"Drop a bomb in Morph Ball form. You'll fly upward if you're hit by the explosion."
Mega Bomb - "Drop a stronger bomb with a longer fuse. Only one can exist at a time."

Bombs in Metroid Prime

The Morph Ball Bomb can be used to break cracked walls and to activate certain devices. If the Morph Ball is near a Morph Ball Bomb when it explodes, the concussive force of the explosion will lift the Morph Ball into the air. This tactic is also known as the Bomb Jump. The Morph Ball Bomb can easily demolish objects made out of Brinstone."

Metroid Prime manualEdit

"Samus will be vulnerable when she first gets the Morph Ball, but she'll soon find Bombs to arm herself. Samus has an unlimited number of these energy-based explosives, but she can only drop three at a time. Bombs can be used to destroy weak walls as well as enemies."

Smash TipsEdit

"Samus morphs into a ball and drops a bomb. You can use the explosion to gain a little height."

Metroid: Samus Returns Samus Screen dataEdit

"A Bomb specially designed to be used with the Morph Ball. While in Morph Ball form, press [Y button] to set a Bomb."


  • It is unknown how Samus generates these bombs, or how the energy stays in a sphere shape until detonation.
  • The only time Samus ever demonstrated the use of the bombs outside her Power Suit was in the original Metroid.
  • In Metroid Fusion, the bombs noticeably take longer to detonate than in the other 2-D games, making it impossible for Samus to do an infinite Bomb Jump. This is one of many changes made to the game to prevent Sequence Breaking.
  • Interestingly, in games such Metroid Prime 2: Echoes, should Samus place a bomb in mid-air, it will remain there. However, should she place it over a mobile platform, such as the ones used by the Morph Ball in order to move up and down, the bomb will move along with it.
  • In Brawl, the sound that the Bomb makes when laid resembles that of Samus's grunts when she is attacked in Super Metroid.
  • Bombs apparently defy gravity, as they do not fall after being placed, save for in the Super Smash Bros. series and when using the Five-Bomb Drop technique.
