The Power Beam (sometimes called Normal Beam[1][2][3][4]) is Samus' standard beam weapon, which she begins with throughout the Metroid and Metroid Prime series.

Metroid Series

Throughout the Metroid series, the Power Beam is Samus' original beam weapon, but as she progresses, she can upgrade her Power Beam to make it a more powerful beam weapon. It wasn't until Super Metroid that Samus could combine all of her beam weapons into one, with the exception of the Spazer and Plasma Beam (though this can be done through glitches, and doing so affects gameplay or damages the save file). Super Metroid is also the only known 2D game where Samus can activate or deactivate her beams.

Metroid Prime Series

Much like the Metroid series, Samus can use more powerful beam weapons. However, similar to the function of Metroid and Metroid II: Return of Samus, Samus cannot combine her beams in Metroid Prime, Metroid Prime Hunters, and Metroid Prime 2: Echoes, and is restricted to using one at a time, with the exception of the Charge Beam. It isn't until Metroid Prime 3: Corruption that Samus can fully combine the beam weapons she collects.

Unlike its 2D counter-part's rate of fire, which is dependently entirely on the game engine, the Power Beam has the highest rate of fire. Interestingly, in Metroid Prime 3: Corruption, the rate of fire remains the same when combined with the Plasma and Nova Beam. Although the Power Beam isn't the most powerful, it can become more powerful when combined with the Charge Beam. Another advantage, which is only demonstrated in Metroid Prime Hunters and Metroid Prime 2: Echoes, is that it has limitless firepower.

  5. "This is Samus's standard beam, which you can fire continuously by rapidly tapping the A Button. As with all beam weapons, the Power Beam becomes much stronger once Samus finds the Charge Beam power-up. Once Samus has found the Charge Beam, press and hold the A Button to charge up her shot, then release the A Button to fire a powerful blast." Metroid Prime Instruction Booklet, Pg 17
  6. "Fire the Power Beam continuously by rapidly tapping the A Button. It becomes much stronger when Samus uses the Charge Beam. Hold the A Button to charge (which also engages a tractor beam effect that draws power-ups toward Samus), then release it. The Power Beam can open blue hatches and has infinite ammo."

  9. "The beam you can use from the beginning is called the Power Beam, and it will become more powerful as you obtain new functions. When the player acquires the new beam it will merge with the previous beam, adding new abilities to the beam, while keeping the properties of the previous beam."
