The Spazer Beam, also referred to as the Spazer (スペイザー Supeizā?) for short, is a beam Samus Aran occasionally obtains during her adventures. When shot, the beam splits into three lasers. This weapon originally appeared in Metroid II: Return of Samus as the Spazer Laser Beam[1] and returned in Super Metroid as the Spazer Beam.

The beam's mechanics differed between the games. In Super Metroid, if one beam hit a target, the other two would disappear as well and the target received the full damage of the three-beamed shot. However, in Metroid II, the three were separate, and would not do this, exactly as the similar Wide Beam upgrade does. The crab depicted on the upgrade bears a strong resemblance to the Tallon Crab.

Official dataEdit

Metroid II manualEdit

"A three way beam with an extremely wide focus is fired when this beam is discharged."

Super Metroid manualEdit

"The Spazer Beam is a three beam attack allowing you to hit objects in a wider range."


  • In Metroid II: Return of Samus, the word "laser" in the beam's title seems to suggest that the Spazer is a laser weapon.
  • In Super Metroid, the Spazer was incompatible with the Plasma Beam. If both were simultaneously selected with a variety of other factors, the game would glitch with results such as the Murder Beam, Spacetime Beam and the Chainsaw Beam.
  • The Spazer Beam is replaced by the Wide Beam in Metroid Fusion, and the Diffusion Beam in Metroid: Other M.
  • In trailers for Fusion, Samus appears to use the Spazer Beam. In-game, the SA-X also uses a special version of the Spazer combined with the Plasma Beam.
  • The Wave Beam in Metroid Prime and Other M is also composed of three shots, although the number of shots does not have anything to do with its damage.
  • The Spazer Beam is one of three items not re-used in Metroid: Other M, the others being the X-Ray Scope and the High Jump Boots.
  • Previously unreleased artwork featured in the art booklet shows that the Spazer Beam may have been planned for inclusion in Metroid Prime but was later scrapped.
  • Although spelled "Spazer," a nano-laser technology called "SPASER" (Surface Plasmon Amplification by Stimulated Emission of Radiation) was first described by Bergman and Stockman in 2003.
  • In Super Metroid, while it is intended that the High Jump Boots be acquired first to obtain the Spazer Beam, a Wall Jump can be used to reach it early.
  • The word "Spazer" is possibly derived from "split laser," as the Spazer splits into three upon being shot.
