Damage	Devastating effects on targets
Obtained	Coupled with Phazon Suit and PED Suit

In Metroid Prime, the Phazon Beam is used against the final boss, the eponymous Metroid Prime. When the corrupted Phazon Suit comes into contact with liquid Phazon, it goes into "Hyper-Mode", supercharging Samus' Arm Cannon and allowing her to shoot a continuous stream of destructive energy. It automatically arcs towards enemies. The Phazon Beam is the only weapon that can damage the second form of the Metroid Prime.

Unlike the Hyper Beam, which can be fired anytime, Samus Aran must step into a small pool of pure Phazon to use the Phazon Beam, which means it can only be used during the last boss fight.

In Metroid Prime 2: Echoes, Samus also uses a sort of Phazon Beam, although it is not an actual power-up. In the final boss fight, Dark Samus occasionally fires tiny balls of Phazon that Samus must catch with the Charge Beam. When three of these Phazon balls are absorbed, Samus can fire them back at Dark Samus to hurt her (absorbing more than three does not increase the strength of the beam). Any beam will work with this, so charged Phazon versions of the Power, Dark, Light, and Annihilator Beams exist (there is no difference other than minor graphical ones, however and using the Light, Dark, or the Annihilator Beam will not waste ammo when fused with Phazon energy). Strangely, when this shot is used outside of the fight (via hacking), it can open any door (with the exception of the seeker missile doors, due to their unique opening mechanism), break any substance, and does extensive damage to bosses.

In Metroid Prime 3: Corruption, Samus can enter Hyper Mode manually using her PED Suit, and use her Phazon energy/health to power it, and fire single blasts of phazon energy. The charged version of this has Samus shooting out a stream of Phazon energy, dealing significant damage to nearly any enemy. As the charged shot is firing, the tip of the Arm Cannon spins, and the whole action looks similar to a Gatling gun firing.
