Who is this?

I would say people that this has to be what the Space Jockeys look like. Well dont on the image very good effort.

I think it is safe to say that the huge stone face is not a human face but a Jockeys face, thats what it looks like to me, makes sense.

It's KRATOS lol....I like the look, and perfectly happy that if he is indeed the JOckey - nothing is confirmed of course, he might be the equivalent of an Igor from Frankenstein!

Yeah, that has to be the Jockey, although I am upset that what we thought was the Jockey (from Alien) is just a "suit" - dissapointing.

LOL suprising i would not be bothered if this is what the space jockeys look like. We have to remember they are very advanced evidentally. So this is what they would most likely be like. Let me put it this way. I think i could sit down and have a beer with this alien and talk physics but the jockey the way people expect it ....erm....no. I dont know why people think the jockeys have to be monstrous. They are advanced they are not going to be like the xenos are they. This is more realistic and I am happy about that. Whats the point being a big monstrous creature with a fat arse but he cant speak or pick up a hammer, doesnt make sense. This guy looks smart and advanced I think. All of this and i find out he is amercenary on steroids and has no hair............ sods law lol

At least it isn't a human(it could have been one). His face reminds me of an embryo, especially his ears. -lol I just see it has 4 fingers- I start to believe it is an SJ

i dont think they would reveal the SJ in the trailer ... not 6 months before ...

I agree with Frantz. There are too maybe and what ifs right now to say for certain who or what this is.

I think this is the end result of the crew member being mutated or the baby that Shaw has. Either way possibly a way of ressurecting a dead race of Engineers / Space Jockey's?? This one being either the Engineer and the Elder Engineer being the one that pregnated Shaw when she is dragged away in the sand storm .........

This has to be the SJ. Just look at his size, compared to the human standing up on the same platform with all the planet holographs. I am disappointed with this though. I visualized the SJ as a giant scary yet intelligent biomech creature. Not a damn Voldemort-like on a hi tech suit cliche. And the 'mutated' human hints are even worse. Why everyone want any form of zombies in their movies nowadays? is way overdone and I am disappointed and surprised that someone that has done so many original things like Ridley is going this path now. Big let down :(

It's only a let down if you assume it is true. So far we have no proof of any of this. Only our wild (and sometime educated) guesses.

This could just be a hologram that is to be familiar to the species finding the star chart???

can be everything ...even a battle android following the prometheus crew for security , after all scott didnt say that there could be more than one android ?

i'd hoped the jockey would look more bio mechanical, like the suit, the ship, etc.

and if i can add something , the actor is Embree ( imho )

@Rakkasan, You are right, and I certainly hope is not the case. And I have seen other two interesting images in the trailer that might as well explain this a bit. The part where the woman falls on her knees, you can see a bald guy on a chair with Fassbender and another person. This same bald guy is seen on the part where they are heading out a door and two crew members are shooting at something. So I am guessing this strange bald man could be a 'mutated' human that eventually turns into this figure we see in the image. This could match the premise of the movie too, being this creature or mutated human, the one that pisses off the Jockeys by stealing the tech, ship, dna, or whatever the Jockeys have. This creature could be the one jumping from the top of the vehicle on the other part of the trailer too... Because consider my last theory, it could be just too bad for Ridley to allow people see the high premise of the movie which is the Jockey in the trailer, after so much anticipation. It makes no sense, if that is the case.

I do not for the LIFE of me understand how in the heck anyone could possibly be disappointed with bloody Anything in a Film they have YET TO SEE !!!

Hold on, I have an idea that may please the nah-sayers... Maybe this guy is human, or partly, and possibly under company orders steals the derelict, intending to take it back to Earth so that "the company" can get their hands on the cargo within, the Alien eggs. Using the star map he plots a course to Earth before sitting in the chair and "merging" with the Space Jockey bio-mechanical suit. Realising someone is attempting to steal their technology the Space Jockeys somehow order one of the eggs to open. Meanwhile, captain Janek, realising the threat the Derelicts cargo poses to Earth crashes the "Magellan" into the alien craft, causing it to crash. This way the Space Jockeys remain a "relative" mystery, and Alien is set up not just in respect to the crashed Derelict but also the foreknowledge they had about the Derelicts position and cargo.

http://cache.gawkerassets.com/assets/images/8/2011/10/space-jockey---pg.-99.jpg i can buy the concept that the jockey "skeleton" is an exosuit meant to protect the wearer or maybe even keep them in suspended animation for long travels. however, the shape of the head and the body proportions look totally different. wouldn't such a suit conform to the general body shape of the wearer? i mean the space jockey suit design has the arms going back behind where the collar bone would normally extend, and the shape of the head and the mouth area is totally inhuman. yet on the trailer still, it's looks generally human. something weird is going on. i am 70 percent sure that is not the space jockey.

@walterhiller, I think you're on to something. None of the physiology of this guy in the room matches up with the original jockey "suit." It was apparent to me from the beginning that the spacing of the eye "holes" on the jockey in Alien couldn't be a helmet for this human looking fellow - as he clearly is the same fellow the giant stone head is designed after. The eyes are too close together to see out of the holes on the original jockey head OR the head on the table in the lab in the trailer. (you could get around this I suppose by saying the eye holes are for cameras...but...c'mon!) Also - while one of the fingers on the giant could just be moving and unseen (pinkie hidden behind ring finger because of the angle, etc.) - if he DOES only have 4 fingers - then why would he use a suit that has 5 - LOOK AT YOUR IMAGE OF THE JOCKEY SCULPT - FIVE FINGERS on that hand - gripping that lever with an opposable thumb and four regular fingers. Also - remember that still from the ampule room with the giant fellow's body in the foreground? http://images.allmoviephoto.com/2012_Prometheus/2012_prometheus_002.jpg The chest and legs on that guy seem different (elongated and thinner) from the SJ room bald fellow...no? The bald guy is very muscular, the dead body not so much... Perhaps the thing on the floor is just the bald guy in his "suit"... but look at the width of the hips of the suit compared to the chest, etc. The bald guy is stocky and the "suit" doesn't seem to be. Or am I just looking for ANY reason to believe the baldy isn't a SJ?!!
