Metroid Prime Hunters - Tools of the Trade

From the official Hunters website:

"Little is known about the mysterious bounty hunter known as Sylux, other than the fact that Sylux harbors an intense hatred for the Galactic Federation and the bounty hunter who has helped the Federation time and time again - Samus Aran."

The enigmatic Sylux uses the Shock Coil to drain energy from nearby hunters. His alternate form, Lockjaw, can hover and launch some little projectile bits as well.
