Sharp-looking Charge Beam―just the way I like it!

Head Quarantine Officer

The Charge Beam (チャージビーム Chāji Bīmu?) (occasionally referred to as the Charge Shot) is a power-up that allows Samus to charge up her current beam and release a more potent version of it. The Charge Beam first appeared in Super Metroid and has appeared in all games since (save for Metroid Prime Pinball). In some games, Samus acquires it, and in others she has it by default and never loses it, or does lose it and recovers it later.


The Charge Beam is compatible with most[note 1] beam weapons. After acquiring the Charge Beam, Samus can focus energy into her Arm Cannon and later release it at any time. This process can be seen in Metroid: Other M. The resulting charged shot is many times more powerful than firing a normal beam (though the exact power varies between games) and is capable of damaging certain enemies that a standard beam cannot. In fact, some enemies can only be damaged by charged shots. The Charge Beam's appearance is reminiscent of the beam(s) currently in use and usually takes the form of a concentrated ball of energy.

In Metroid Fusion, after Samus regains Charge Beam capabilities, both the normal shot and the charged shot are actually made up of two smaller shots which form a crescent shape and do slightly more damage. When firing a charged shot, the flare near the Arm Cannon can also deal damage. Fusion is the only game where obtaining the Charge Beam actually alters the normal beam shots.

Super Metroid: The Official Nintendo Game Guide

Strength-wise, the Charge Beam's damage varies between games; it can be slightly weaker, equal or stronger than a standard Missile. Even so, there are still some things that only Missiles can damage, so obtaining the Charge Beam does not render Samus' Missiles completely useless. Also, the Charge Beam can be used as a backup weapon when Missile ammunition runs out during boss battles.

Metroid: Other M provides a Charge Beam enhancement in the form of Accel Charge pickups, increasing the rate at which the Charge Meter increases.

Also in Metroid: Other M, the Charge Beam is used during Overblast and Lethal Strike, dealing a heavy blow to the enemy. In addition, when SenseMove is performed, Samus can instantly charge her beam to maximum, resulting in a possible counterattack. The Charge Beam is more important than in previous games, as it is often needed to trigger switches to progress. As Missiles can only be used in Search View in Other M, the Charge Beam is also needed when Samus needs to move around the area or face multiple enemies at once. Additionally, since Missiles can only be restored by Concentration, the Charge Beam becomes more important for preserving Missile ammunition or acting as a backup weapon when Samus cannot use Concentration due to battle circumstances.

The Diffusion Beam found in Metroid: Other M and Metroid Dread is a charged shot that explodes violently upon impact.

The Charge Beam plays a much larger role in Metroid: Samus Returns, where Charge Doors require a charged shot to open. Additionally, charging the Ice Beam greatly increases the time taken for enemies to defrost, as it would normally take only around 2-8 seconds, depending on the enemy.

Raven Beak attempts to use the Charge Beam on Samus after placing the latter into a neck lift.

Prime series[]

The Charge Beam in Metroid Prime 3: Corruption.

In the Prime trilogy, the Charge Beam is mostly the same as its 2-D counterpart. Charging the Beam in use increases its power and the size of the shot, but also makes the shot noticeably slower. Some enemies are able to dodge it because of this. When in use, the Charge Beam causes a graphical effect to affect the Arm Cannon which differs depending on the Beam (although this was removed in the Wii version of Metroid Prime). Samus starts out with the Charge Beam in Metroid Prime, but it is damaged and malfunctions along with Samus's Varia Suit, Morph Ball, Missile Launcher, and Grapple Beam due to an explosion and electrical surge during Samus's escape from the Frigate Orpheon. She regains it in the Watery Hall in the Chozo Ruins.

A factor in the Prime series is the well-hidden Charge Combo abilities, found as separate items. These special add-ons to the particular beams add many special effects and can be highly damaging.

The Charge Beam in item form

In Metroid Prime 2: Echoes the Dark Beam, Light Beam, and Annihilator Beam have different effects compared to their normal shot. The Dark Beam's is called the Entangler and creates a compact blob of dark matter that, on contact with an enemy, entangles it with dark energy. The energy hardens to a physical crystal structure, preventing movement and making it vulnerable to a Missile, similar to the Ice Beam from Prime. The charged Light Beam is named the Lightblast and fires a volley of fast, mildly-homing spherical projectiles; when used close range it can be highly damaging, similar to a shotgun. Charging the Annihilator Beam causes the shot to stun some creatures such as Space Pirates and is appropriately named the Disruptor. Interestingly, it has a tendency to kill the Dark Pirates in a single hit.

The Prime variants of the Charge Beam also have a tractor beam effect on pick-ups: as long as Samus holds the charge, it drags the pick-ups to her, allowing her to collect them from hard-to-reach areas. The Charge Beam also has the capability of gathering Phazon particles to fire a Phazon-concentrated shot, as seen in the final battle with Dark Samus in Echoes.

Also, the Charge Beam in the Prime trilogy is capable of destroying some objects which are said in scans to require 'explosive damage' to destroy (referring to Missiles).

In addition, the Charge Beam can be fired in short bursts, unlike the 2-D versions. This means that Samus is not completely vulnerable when charging. The damage with the minor shots is weaker than the full charge but stronger than the standard shots, and travel slightly faster than fully-charged shots.

Its appearance also varies between the Prime games, unlike the 2D games, where the only difference is the spark pattern. In Prime, the fully charged Power Beam looks like a ball and is both yellow and purple. In Echoes, it again looks like a ball, but pulses when fully charged and is only shades of yellow. In Corruption, the Power Beam's fully charged shot has a blue tinge in addition to the yellow, and it is slightly more disk-shaped than spherical.

Super Charger MOD.

Federation Marines in Metroid Prime: Federation Force carry weapons that have charging functions similar to the Charge Beam. The only differences are that it takes longer to charge compared to Samus's, and strong breakable objects cannot be destroyed unless the beam is fully charged. The Super Charger MOD increases the damage output of uncharged and charged shots by 20, 30 or 50%. Only one copy of it can be equipped at a time.

"Increase Power Shot and Charge Shot damage by 20/30/50%."

Super Smash Bros. series[]

"What's the matter? All I said was that Komaytos look like little Metr—"

The Charge Beam in Super Smash Bros. Brawl.

In the Super Smash Bros. series of games, the Charge Beam is Samus' standard B attack, known as Charge Shot. When performing the move, Samus drops to one knee as she charges a spherical blast of white/blue energy. If disrupted during the process, the charging stops. When charging is finished, the energy of the beam charge disappears and is replaced with sparks at the Arm Cannon barrel, that flash until Samus fires the blast. This is the only instance where Samus is able to keep her charge. If Samus performs her dodge while charging, progress on the charging is recorded, and she can continue. She cannot charge the beam while in midair; instead, she will simply fire a normal shot. If Kirby swallows Samus and copies her ability, he will possess the Charge Beam and her helmet, though amusingly not her arm cannon.

In Super Smash Bros. Ultimate, the Charge Shot can now be charged or canceled in midair. However, doing so can leave Samus vulnerable to attack. As with all of her moves, Dark Samus shares Charge Shot with Samus as her standard B attack, though her charging and firing animations feature Phazon effects.

In Super Smash Bros. for Nintendo 3DS and Wii U, the move can be customized. There are three variations, with the other two being Dense and Melee Charge Shot.

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


Super Metroid has two hidden Charge Beam features. The first takes place when Samus holds a charge and enters the Morph Ball form, resulting in the Five-Bomb Drop. The second technique activates when Samus holds a charge while only one other beam (besides the Charge Beam) is equipped and while highlighting the Power Bomb. This allows her to unleash a Special Charge Beam Attack at the cost of Power Bombs. In Super Metroid, Metroid Fusion, Metroid: Zero Mission, and Metroid: Samus Returns, Samus can perform the Spin Jump Attack by using a fully charged shot and a Spin Jump. However, this ability is eventually rendered redundant by the Screw Attack.

Metroid Prime 2: Echoes has special enhancements for charging the Beams found on Aether. The Dark Beam produces an Entangler, the Light Beam creates the Lightblast, and the Annihilator Beam fires a Disruptor. When these beams deplete the Beam Ammo, they must charge to fire normal shots.

Metroid: Other M also has four related techniques. Firstly, the Five-Bomb Drop can be performed, resulting in a pentagon-shaped arrangement of bombs around Samus. Secondly, if the Charge Meter is filled or nearly filled while in Morph Ball form (similar to charging a Power Bomb in this game, although it can be done before these are authorized), then unmorphs, she will fire a charged shot instantly as she unmorphs. The Overblast and Lethal Strike can both be used with the Charge Beam to deal large amounts of close-range damage.

  • In Metroid: Zero Mission and Super Metroid, the Charge Beam can be skipped entirely, as it is not required to advance through the game. In the former, one merely has to defeat Charge Beam Beast and leave the upgrade floating in the air. It never disappears, so it can be recovered at any time.
    • It is neither revealed nor explained how and why the beast possessed the Charge Beam. It is possible the Charge Beam Beast unintentionally obtained it while digging through the tunnels of Brinstar.
  • Strangely, the charged Power Beam in Metroid Prime Hunters has a limited homing capability, closing in on doors and enemies. It is mostly overlooked because it requires some distance for the homing effect to be noticeable. This is the only game in which the charged Power Beam does this. This homing feature may have been added since lock-on is not present in this game.
  • The Charge Beam is not referred to by name in Metroid Prime 3: Corruption but is instead referred to as a "charge module" to the Power Beam in the logbook.
  • The sound effect when charging the Charge Beam in Other M is the only recycled sound clip in the game from the Prime series.
  • In Metroid Prime 3: Corruption, the Nova Beam's charged shot actually travels much faster than the standard shot, unlike the other beams'. It also happens to be the fastest traveling weapon in the game.
  • The distortion effect that occurs when the Charge Beam is fired in Metroid Prime was created by Jack Mathews.
  • Acquiring the Charge Beam in Prime contains a debatable "sequence break" as it can be acquired before the bombs, however, the Hint System does not detect it until Super Missiles are obtained.
  • In Metroid Dread, the charged Power, Plasma and Wave Beams have different particle and sound effects.[1]
