Sylux

Sylux is a powerful Bounty Hunter who appeared in Metroid Prime Hunters. It is probable that he also appeared in the 100% ending of Metroid Prime 3: Corruption as the mysterious ship that pursued Samus (there is no proof to confirm this). Very little is known about him, other than he is a sworn enemy of Samus Aran and has a strong hatred for the Galactic Federation.

Biography
Very little is known about Sylux or why he hates the Galactic Federation or Samus Aran. He is very skillfull, proving himself as one of the best Bounty Hunters around. He is a master of stealth with excellent marksmanship. Sylux harbors a strong hatred for fellow Bounty Hunter Samus Aran and is constantly tracking Samus in an attempt to be rid of her forever, though it is unknown why he hates her so.

Looking at his overall humanoid shape and the humanoid hand holding the Shock Coil (his weapon of choice), it is possible and currently assumed that Sylux could be human. His species was never given.

Sylux may appear in future Metroid game series, since he is portrayed more as Samus' main rival. He is the only Hunter whose ship appears in a game, as well as his suspected ship's appearance in Metroid Prime 3.

Gameplay
Like all other Hunters in the game, Sylux is capable of defeating Samus and taking one of her Octoliths. In order to complete the game, Samus needs all of the Octoliths, and thus must fight her thief again in order to gain it back.

Sylux' weapon is known as the Shock Coil. The Shock Coil was a prototype weapon under development by the Galactic Federation, but was eventually stolen by Sylux, along with plans for his power suit and his ship, the Delano 7. Delano 7 is encountered twice in the game, and it is the only Hunter ship other than Samus' seen in the game. Interestingly, despite hating the Galactic Federation, almost all of his equipment were created by them. A ship that greatly resembles the Delano 7 can be seen following Samus after the end credits in Metroid Prime 3: Corruption if you obtain a 100% item collection rate.

Sylux has an alternate form known as the LockJaw. In this form, Sylux becomes a ball of green energy the size of Samus's Morph Ball form, surrounded by two entwined, metal bars that look like a deformed version of his ship with energy threads connecting them together. He can deal a large amount of damage in this form and is very agile. While in this form, Sylux can drop two bombs and connect them. Once a foe is in range, a third bomb can be dropped which will enclose the enemy and kill it.
