This is Sylux from Metroid Prime Hunters (and one of my favorite hunters). Keep him away from my GF trooper minifig.
About this creation
Sylux has one goal and one goal only: to obliterate the Galactic Federation (and preferably Samus, too). Sylux wields the Shock Coil, an illegal technology that fires rapid blasts of neutrinos. When Sylux uses this weapon, he regains health.
