For other uses, see Bomb (Disambiguation).

Bombs (ボム Bomu?) are the basic weapons for Samus Aran's Morph Ball.


Bombs have appeared in every Metroid game. In the 2D games, they appear as metal capsules that flash until they detonate. In the Metroid Prime series, they're depicted as balls of blue energy. Metroid: Other M features a combination, with metal capsules that explode blue light.

Although bombs are not of great use on many normal enemies, they can break certain objects, activate Bomb Slots, and are essential in defeating several Bosses, such as Flaahgra and Amorbis. Bombs can also destroy Bomb Blocks in the 2D Games, Sandstone in Metroid Prime, and Talloric Alloy throughout the Metroid Prime Trilogy. A more powerful version called the Power Bomb is also available.

When Samus is near a detonated bomb, she will be propelled upwards. This is a Bomb Jump. In some games, it is possible to perform an infinite Bomb Jump, which can be used to reach normally inaccessible areas. Samus can lay up to three bombs at a time, or four in Super Metroid, Metroid Fusion, Metroid: Zero Mission, and Metroid: Samus Returns. The time it takes for a bomb to detonate varies per game, with 30 frames being a full second:

  • Metroid: 24 frames
  • Metroid II: Return of Samus: 47 frames
  • Super Metroid: 30 frames
  • Metroid Fusion: 40 frames
  • Metroid: Zero Mission: 15 frames
  • Metroid Prime Trilogy: 30 frames
  • Metroid Prime Hunters: 43 frames
  • Metroid: Other M: 25 frames
  • Metroid: Samus Returns: 26 frames

Metroid Prime 2: Echoes features 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 hers. Unlike Samus, however, the Bomb Guardian can produce many bombs simultaneously.

Bomb Jumps can be performed in Metroid Prime 3: Corruption, 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, Metroid Prime Trilogy and Metroid: Samus Returns.

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.

"The Morph Ball Bomb is the default weapon used by Samus Aran while in Morph Ball form.
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 flash
"Morph Ball mode includes the ability to drop small energy explosives. These Bombs are available in an unlimited supply but only three can be launched at one time. Use Bombs to destroy small obstacles and enemies."
Metroid Prime manual
"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."

Melee Bomb

Samus detonates two bombs in Super Smash Bros. Melee

In the Super Smash Bros. series, the Bomb is Samus's Down Special and is apparently made of metal like in the 2D games. In Super Smash Bros. Ultimate, the move is shared with Samus's Echo Fighter, Dark Samus.

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.

An update to Ultimate on January 29, 2019 reduced the vulnerability Samus and Dark Samus have when using this move.

Non-canon warning: Non-canonical information ends here.


  • 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.
  • Bombs appear to 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.
    • In games such as Metroid Prime 2: Echoes, should Samus place a bomb over a mobile platform, the bomb will move along with it.
  • Samus' bombs are the only weapon capable of destroying the bombs ejected through Mother Brain's mouth in Super Metroid.
  • In the Captain N: The Game Master episode Metroid Sweet Metroid, Kevin and Duke use a bomb obtained from a hallway in Metroid to blow open a door leading to Mother Brain's lair. In this show, bombs are depicted as functioning like grenades, with a pin that must be pulled to activate a timed explosion. Its use in this episode reflects the need to bomb secret passageways to proceed in Metroid, as well as using missiles to open Red Hatches.
  • Infinite Bomb Jumps can't be performed in Metroid Fusion, as the bombs detonate too slowly and provide no mid-air momentum. This is one of several traits that prevents Sequence Breaking.
  • In the Super Smash Bros. series, the sound that the Bomb makes when laid resembles that of Samus's grunts when she is attacked in Super Metroid.
  • In Nintendo Land, Charge Bombs are fired from the Arm Cannon rather than dropped by the Morph Ball.
  • After Dark Samus uses a Bomb in Super Smash Bros. Ultimate, she very briefly assumes the real Samus's idle pose.
