Pretty sure the Stalker is just a frame filled with Kuva, a.k.a the "souls" of all the high Orokin we slaughtered, since he was there that day and saw it go down. It would explain the whispering you hear when he's showing up, the fact that he can dispel our powers, use weapons that only a warframe could wield with enough strength to be effective, and that he disappears in a fashion other than invisibility
