Agents Of S.H.I.E.L.D.: Five More Theories About The Blue Alien

Turns out our readers have thought about that blue alien from Tuesday's episode of Marvel's Agents of S.H.I.E.L.D. Like, a lot. Between the comments thread, the e-mails we've received and just plain digging in and doing a little extra homework of our own, we've taken the original batch of theories we had (which really just boiled down to, "Which are the blue aliens of the Marvel Universe, and what studio owns their live-action rights?") and expanded wildly on them. Here are some of the best ideas we've stumbled across in the last couple of days.

Captain Marvel Mar-Vell is a character we referenced when making note of the popular theory that the alien might be a Kree, one of the most obvious choices and popular theories among both our readers and basically everyone online. More specifically, though, a number of fans pointed out to us that the Ultimate Comics Universe features a Mar-Vell whose full name is Geheneris HalaSon Mahr Vehl. Commenter Jason Karwowski-Bum pointed out an existing theory that suggests Coulson is Mar-Vell, in the same way that Rick Jones shared a body with the Kree hero in the comics. In that scenario, both of them were near death, but by merging their consciousness, Mar-Vell's powers were able to pull Jones's body back from the brink while Jones's now-recovered both provided a ready home for the subconscious of Mar-Vell.

Sakaaran Reader Jason Rye had a unique perspective that makes a lot of sense and ties into Guardians of the Galaxy, which is more likely than not the function of an extraterrestrial, since it's not as though we're going to see resolution to GH325's plot thread in Captain America: The Winter Soldier. And the bigger the plot thread on Agents of S.H.I.E.L.D., the more likely it is to tie into the larger Marvel Cinematic Universe. His theory? The alien is "a gray skinned Sakaaran, that looked blue due the liquid." He notes that the will appear in Guardians of the Galaxy, apparently replacing the Badoon in the film since Marvel can't use them. He (rightly) points out that it's likely, then, that the race have already been to Earth since the Badoon play a major role in Star-Lord's origin and any race filling in for them would likely have been the ones that killed Peter Quill's family in the upcoming movie.

Luphomoid The blue-skinned race that Nebula belongs to were an obvious one that slipped our mind the first time around--especially because as we've seen her, she's got the metal plates and things on her body that could explain the very geometrically-shaped scars on this corpse. Could he have been subjected to those same kinds of implants at one point, before they were removed -- either by his own people, by S.H.I.E.L.D. or by someone in between?

Skye's Real Dad There are a ton of variations on this, but the bottom line is, there are a fair number of people out there thinking that the reason Skye is an 0-8-4 is that whatever this guy is, he's related to her--probably literally. If not her biological father, he's at least the person responsible for bringing her to Earth and putting her in the hands of the S.H.I.E.L.D. agents who saved her from a life of being poked and prodded. If it's a Kree, it could be that Skye is a "pink Kree," something that exists in the comics and looks basically like a regular human. It's hard to say whether Skye fits the bill, though, because she hasn't really had enough field work to indicate whether she's got the enhanced strength compared to regular humans. Our gut is to say no, since she's been overwhelmed in fights a couple of times, but then they could also decide that different rules apply to the movie-and-TV Kree than the comics Kree. This could also tie into the theory up above, in that Skye could be the MCU version of Phyla-Vell, the daughter of Mar-Vell. Lewis Salw has a different theory about Skye, though: She's Jessica Jones, and will be the first cast member announced for the Netflix series. This one seems a bit farfetched, but Lewis rightly notes that Agents of S.H.I.E.L.D. would be a great launching platform for Jessica Jones and The Defenders if handled right. It's a construct of some kind What if this being isn't really severed in half as a result of a spacecraft crash or a battle, but because his lot in life is to be there, in stasis forever, providing blood for the GH325 serum? Some readers have pointed out that if S.H.I.E.L.D. had found a way to genetically-engineer a being from alien DNA (either Chitauri or something else), there's no telling just how it would look...or how horribly mangled it might come out the other end.
