After reading the post about Dark Samus a few pages back, I'd have to agree that he (yes he, although I believe it's genderless) wouldn't be a clone of Samus. Dark Samus doesn't have any weapons that Samus does, except for using the blaster. Here would be his special moves:
Standard Special: Phazon Beam
Dark Samus shoots out strips of phazon energy that temporarily corrupts the enemy. There's no charging here and I'd say it could work out like Bowser's fire breath in that it fades slowly the longer you use it.
Down Special: Meteor (give me a better name for this

)
You know that meteor attack Dark Samus used in Echoes the first time you battle him? Say hello to Dark Samus' down special. Dark Samus turns into a ball of phazon energy and strikes the ground hitting anyone in his way.
Up Special: Particle Formation
Ok we all know Dark Samus can turn into a bunch of phazon particles at will right? Well...when the up + b combo is used, Dark Samus could burst into a bunch of particles and reform in any direction you tilt the control stick. Kind of like teleporting, but much cooler imo.
Side Special: Metroid Swarm
I'm not too sure about this one but I couldn't really think of anything else. Dark Samus is really Metroid Prime who is the mother of all metroids right? (I could be wrong but) So side special could be Dark Samus summoning a couple of metroids and sending them to attack a nearby player.
And of course he would be floating while running just like mewtwo. And there's just a bunch of cool stuff Dark Samus could do.
So yeah, Dark Samus would be a cool character imo. What do you guys think? Does he really have a chance?
