read everything on the site, read everything on the other site,
and still i have no fucking clue as to the origins of this fucked up incognito guy, or why is he supposedly so 'real'

in the show, we are given these clues:
1. that scene with the wrecked car in some desert in the USA, where you see some scrawny fingered hand sticking out of the window, most likely incognito's
2. he says that much like alucard he also obeys a master.
3.he has some kind of weird magical powers which it seems only he is able to summon, "the dark continents magic", as he refers to it.
4.he has the ability to consume\ create matereal objects and living beings alike from within his flesh.
5.he is also able to summon (probably)ancient egyptian devils from hell
6.his main weak point is apparently silver, like most undead (in hellsing), though he is much more resistant to it than even alucard himslef, and can very quickly regenerate, with no regard to how badly his physical form is damaged.
7.according to him, he was created with the soul objective to destroy everything.
searchdestroy.net:
major kreg is the leader of the nzi millenium group from the hellsing mangaLike Alucard, Incognito also serves a master (which is most likely Major Krieg) although it is never confirmed who he or she is.
The Crypt of Hellsing had this profound information to offer about incognito:Aside from his dark abilities he also has a man-made weapon. This freakish vampire carries a machinegun known as an "Armscorps 40mm MGM" and a numerous amount of "FREAK" chips as well. Incognito makes his appearance in the final four episodes of the Hellsing anime and proves to be a worthy opponent towards Alucard. He is later defeated by a silver spear molded from Alucard's partially destroyed handgun, the Jackal.
He looks like a grey and have purple markings over his body as well as having a gun which is attached to his arm
