One of the ongoing mysteries of Marvel's Agents of S.H.I.E.L.D. is the "real" identity of Skye, especially since being revealed as an 084 (object of unknown origin) in the twelfth episode the first time the team have heard about an actual person being given that designation. What we do know about her is that she grew up in an orphanage, and doesn't know who her parents were. This has led to the fans of the show speculating as to her origin and linking her to a variety of superheroes. Given the reveal of Mike Peterson as Deathlok in the episode T.R.A.C.K.S., it seems that Agents of S.H.I.E.L.D. has decided to up the ante on their superhero quota, having previously avoided including such characters. The difference with Deathlok is that there are several different characters who have previously been known as the character, so adding an additional one in Agents of S.H.I.E.L.D. isn't that unusual but some of the fan expectations for who Skye could be would drastically change the origin stories for each of the characters. Skye was seriously injured in the same episode as the Deathlok reveal, leading to the team's investigation of the location where Agent Coulson was revived and one of the major sources of his resurrection... a bright blue alien corpse which was being milked for a medicinal enzyme. However, it seems that Coulson and Skye's reaction to the enzyme were subtly different, which has added more fuel to the fire of the fans expectations. So who is the internet suggesting that Skye could be? Is this some rather clever foreshadowing of Guardians of the Galaxy, or are we seeing the birth of the first original superhero in the Marvel Cinematic Universe? Read on to find out.
