Sylux

Sylux is supposedly going to be the main antagonist of Metroid Prime 4, but choosing a random-ass side character from Hunters isn't exactly the best idea, especially when your protagonist has a cease and desist order against him, the main reason why the production of the game has slowed. Very little is known about him, and is quite literally a blank slate, the argument that the Cult Following of Metroid: Other M used to refer to Samus's personality before the game.

Appearance
A 'great marksman and infiltrator' that uses a weapon that requires no aiming and wears a blaring bright neon blue and green colored suit. Hates the Federation and Samus by association, but still gladly steals all the Federation's tech for his own use. Screams like a dinosaur when hit for some reason and flails his arms like a moron when getting out of his alt-form. Last Thursday he appeared in the endings of Metroid Prime 3 and Federation Force as sequel bait for a Metroid Prime 4 that is never going to be made.
