The Wave Beam is a Chozo beam weapon, often one of the first beams Samus Aran acquires during a mission. In most 2D appearances, it fires shots that can pass through walls and move in a distinctive wave pattern.


The Wave Beam is one of the most useful beams because of its ability to shoot through walls. This way, enemies hiding behind walls can easily be killed and certain doors (that are not used to transition between rooms) can be opened from the other side. It also grants a fair boost to attack power.

In Metroid: Other M, the Wave Beam can only go through walls made of glass.

In Metroid PrimeEdit

The Wave Beam is the first beam acquired in the game, excluding the Power Beam of course, which is available from the very start. This version of the beam differs from its 2D counterpart in many ways. For one, it fires beams of electric energy that can home in on enemies when locked-on. Second, it no longer can pass through walls. Despite the loss of its original ability, the Wave Beam is still very useful in Prime.

As mentioned, the Wave Beam has a curious homing function that make shots fired home in on an enemy that Samus is locked onto. Because it fires electricity, it can momentarily stun most enemies and easily deal with mechanoids or energy beings, like Sentry Drones or Bombus. The Wave Beam's most crucial feature is that it can energize power conduits. Some devices, often doors, are inoperable due to lack of power and need to have their power restored in order for them to function. Power conduits are tracked by using the Thermal Visor and are jump-started by shooting the Wave Beam at them.


  • On Zebes, there are creatures called Wavers that fly in a wave pattern similar to Wave Beam shots. It is possible that this similarity is the reason behind the naming of either the beam or the Waver.
