Role of Sylux and the Pirates in Prime 4?

You’d think that anyone or anything even remotely resembling Samus would be a big fat ‘NO’ for the Pirates—especially after Prime 3, when Dark Samus hijacked the Space Pirate leadership. A debacle ending with her defeat and a significant loss of Pirate forces. Even Federation Force says that both the Galactic Federation and the Pirates are barely hanging on after Prime 3.

Then comes along Sylux. The Pirates size him up and think, ‘What’s the worst that could happen?’

So, what’s the deal with Sylux? Is he a Galactic Federation traitor who defected to the other side? Or is he merely using the Pirates as a means to an end?
