Grand Unifying Guesses/HP Lovecraft

The following are avatars of Nyarlathotep:

 * The Doctor In an odd, woobie-ish sort of way.
 * The Doctor has been described as being "basically what you get if the Crawling Chaos decided to make humanity his pet species instead of just another species on his 'to screw with' list."
 * Alucard
 * Barack Obama, and for that matter, every other President except for Washington, Teddy Roosevelt, and Andrew Jackson.
 * Tzeentch, Nyarlathotep's primary manifestation in the warp, just as the Black Pharaoh manifests in the cosmos, and Barack Obama manifests in the real world.
 * In addition, the Abyss is Nyarlathotep's manifestation in the Route of Ages.
 * Also, if Nyarlathotep is Tzeentch, he is also David Xanatos. After all, who's the God of Magnificent Bastardry?
 * Kaworu Nagisa
 * Wait, so Nyarlathotep is Kaworu, who in turn is Jesus and therefore both Haurhi and the Dunwitch Horror?
 * As a result, Nyarlathotep - and subsequently Azathoth - is the child of Yog-Sothoth, who also incarnates as Bill Gates.
 * Kyon, as the entity which goes around making sure that the creator of reality (Azathoth, aka Haruhi) remains asleep. All the SOS really is is an updated version of the ol' pipes routine.
 * the Fireclown
 * Arioch, Duke of Hell
 * The Master
 * Satan
 * Last I checked, Satan wasn't described as a Magnificent Bastard in The Bible.
 * Anonymous
 * Randall Flagg
 * Number 1
 * BOB
 * J.R. "Bob" Dobbs
 * The Janitor
 * Reynardine
 * Alternatively, Coyote

 * Oogie Boogie
 * Nikola Tesla
 * Wait, what?
 * That is who he was originally based on.
 * Dio Brando
 * The Luggage
 * Guu

 * Loki
 * Morgoth and Sauron
 * In Robert A. Wilson's and Robert Shea's Illuminatus-Trilogy, one character argues that Sauron was actually a Shoggoth.
 * The Cloverfield Monster
 * GLaDOS
 * Giygas, and by extension, Ness.
 * You Cannot Grasp the True Form.

 * Majin Buu
 * Queen Metaria, Death Phantom, Pharaoh 90, Queen Nehellenia and Chaos
 * Naraku
 * The Joker in all his incarnations

 * Uboa, who is also Che Guevara and a Time Lord.
 * If Che Guevara is Nyarlathotep and a Time Lord, he is also Robin Hood.
 * Jack of Blades
 * Edward Cullen
 * Wait..... What did you say?! *slaughtered by fangirls*

 * Also, Aleister Crowley, prophet and messiah of unbound will (Thelema).
 * Sheogorath
 * All hail Megatron!
 * Ba'al
 * Apocalypse
 * Raistlin Majere
 * Black Mage
 * Philemon
 * Wait, Philemon is the source of the Persona-user's power (via his proxy Igor), and in Persona 2, he empowered a group that beat Nyarlathotep.
 * Mind screws should be expected here, really.
 * Considering that, as stated above, Tzeentch is also an incarnation of Nyarlathotep and that he's playing against himself all the time, that's not really a refutation at all.
 * the Venom-symbiote
 * And therefore also its descendants and relatives Carnage, Scream, Toxin, Hybrid, the She-Venom clone symbiote, Dreadface, Payback, and Anti-Venom.
 * Puck
 * Also, O.W. Grant
 * Nyarlathotep created the Death Notes (matches M.O. of giving humanity toys and watching them destroy themselves with it) and the Shinigami are his Avatars.
 * D-Reaper.
 * Tyler Durden.
 * Frank.
 * Yami Yugi, another manifestation of the Black Pharaoh.
 * Preterius. Or maybe Claudandus. One of them for sure!
 * Thinking of it, Claudandus is the more probable candidate here...
 * Pharaoh Akh-en-Aton
 * Hagbard Celine. Apparently.
 * Nyarlathotep is also the force behind the Shadows. Maybe also behind the Vorlons.
 * More specifically, Nyarlathotep is Lorien.
 * The Voice from the Starcraft Frontline comic "The Voice in Darkness" is yet another obvious incarnation of Nyarlathotep.
 * Assuming it isn't Samir Duran.
