The Plasma Beam is a Chozo beam weapon often used by Samus Aran. In nearly all of its appearances, starting with Metroid 2: Return of Samus, it is the strongest beam in Samus's arsenal. It is usually the last beam Samus acquires.
In the 2D Metroid games, the Plasma Beam, when equipped, boosts the arm cannon's attack power to its maximum. Besides this, one of its most useful functions is the ability for shots to pass through enemies, allowing Samus to kill multiple targets at once. When paired with the Wave Beam, beam shots will be able to pass through all but the toughest obstacles, like bosses. However, the arm cannon cannot be equipped with the Plasma Beam and the Spazer Beam at the same time. Often, players choose the former beam because of its usefulness and because it is superior to the Spazer Beam in terms of damage.
In Metroid PrimeEdit
The Plasma Beam is acquired after finding the Grapple Beam in the Phazon Mines, found in a room in the Magmoor Caverns. In this appearance, it represents the element of fire and it fires streams of molten energy, which can, naturally, set enemies on fire. A charged shot can instantly incinerate most larger enemies. It has the second fastest rate of fire in the game, after the Power Beam, and coupled with its high attack power, the Plasma Beam is easily the best beam weapon in the game.
Being associated with fire, it is often used in dealing with obstacles made from ice or Frigidite. It is able to open red doors.
The Beam Combo for the Plasma Beam is the Flamethrower. It functions in a similar manner to the Wavebuster, because being a continuous combo, it consumes missiles over time for the duration of the attack. The Flamethrower, true to the name, projects a stream of fire that can roast enemies alive. Because most enemies can be killed just as easily with a charged shot or repeated normal shots, many players opt not to use the Flamethrower.
It is also in Metroid Prime 3: Corruption, where it can melt various metals and be used as a makeshift melding tool. It is most effective against the robots in Elysia.

- The Light Beam in Metroid Prime 2: Echoes is very similar to the Plasma Beam in the previous game, since its shots appear as thin streams of energy and it burns enemies.
- In the Super Smash Bros. series, some of Samus's attacks include shooting flames from her arm cannon, including her up smash, forward aerial and down attack. It is possible that the Plasma Beam's Flamethrower originated from Super Smash Bros. like the Power Grip from Metroid: Zero Mission.
- The Chainsaw Beam glitch in Super Metroid is caused by carefully adjusting Samus's equipment and arming Spazer Beam and Plasma Beam only.
