Trooper Pirate

Beam Troopers are special types of Space Pirates that were modified so they could use reverse-engineered versions of Samus Aran's beam weapons. However, the copies are flawed; the shielding leaves their users vulnerable to the Beam weapon system and, although quite potent, are inferior to the Chozo-designed originals.

Beam Troopers appeared in Metroid Prime and are found in the Phazon Mines as a relatively common enemy. There are four types: Power, Wave, Ice and Plasma.
