- The show's premise is literally taking elements and characters from the comics and bringing them into the action. It's highly unlikely that heroes from the comics won't show up.
- Stan Lee didn't create Captain America, but he still cameoed in Captain America: The First Avenger.
- There is no rule set in stone as to where does Stan Lee can or can't make a cameo. If the production invites him, and he accepts, then that is all that is needed. As for creation, this is a TV series about SHIELD, and SHIELD has first appeared in Strange Tales #135 (1965) by... Stan Lee and Jack Kirby.
- Confirmed in the promo for Episode 1x13.
- Possibly more if the show is either doing very well or very poorly. But almost assuredly so. At the very least, Natasha and/or Clint at least once or twice (since they are both still presumably part of SHIELD in some form or another, in addition to The Avengers and possibly other missions in deep black ops style).
- Confirmed as of Episode 2, though not one of the 6 "main liners". Nick Fury
- Confirmed. Bill Paxton plays John Garrett.
- Confirmed. Agent Blake appears in FZZT and Jasper Sitwell in "The Hub", the episode after it. They reappear later in the Season too.
- Word of God says yes, Mike Peterson will become Deathlok in an upcoming episode. That episode is 1x13.
- Confirmed. Coulson was dead for DAYS, and apparently crossed to the other side, but bringing him back sapped him of his will to live. He was implanted false memories of going to Tahiti as a way to alleviate the trauma, and "Tahiti" was used as a Trigger Phrase to make sure the implanted memories stuck.
- Some later trailers seem to suggest Coulson is constantly joking and trying to lighten the mood, instead of being The Stoic. Perhaps Tony Snark has rubbed off on him, or perhaps his Lighter and Softer personality might be the form of his PTSD. Perhaps Coulson Came Back Wrong — as a happy jokester or maybe a Sad Clown. It's possible that Coulson's wiseass behaviour is his way to cope with the stress and trauma of coming back from death, convincing himself and others that he's fine.
- Confirmed. Coulson was dead for DAYS and apparently crossed to the other side, but was brought back through a crapload of experimental medicine. When he came back, the trauma of the experience sapped him of his will to live, he was actually BEGGING to be left to die. To deal with the trauma, he was implanted with false memories to alleviate it, but he still subconsciously remembered it and it explains is change of personality. As of "The Magical Place", he now knows the truth. "Nothing Personal" revealed that the resurrection process was so traumatic that it necessitated the use of memory implants to be able to function afterwards, and that Coulson himself was the one assigned to supervise the project, but threatened resignation because of it. Season 2 reveals just how bad Project T.A.H.I.T.I. went and why Coulson feels this bad about it.
- They've already dropped hints that Coulson himself doesn't know the truth of how he survived (though Hill does). Is it a myth arc? Dunno. But it's a thing, at the very least.
- It goes full-arc in "The Magical Place".
- In order to maintain the facade that Coulson died (there by giving The Avengers the push they needed to start acting like, well, The Avengers) Fury pulled some serious strings when Phil was in recovery and maybe even lied to his "One Good Eye" in order to keep him from accidentally blowing the secret. Only a select few higher-ups within the organization are privy to this information and it may or may not ultimately have an impact on future relations between The Avengers and S.H.I.E.L.D. if the truth is ever revealed. As Tony Stark said, after all: [even Fury's] secrets have secrets.
- Confirmed. Hill and the doctor (played by Ron Glass) confirm between them that Coulson's Tahiti story isn't true, and that Coulson believes it.
- Confirmed by Coulson's neurosurgeon in "A Magical Place". This was probably due to the extremely painful surgery they had to do on Coulson's fully-exposed brain while he was fully conscious.
- We've now (as of Ep. 3) seen him fighting and shooting, even though he's "a little rusty".
- Seemingly Jossed as of "FZZT", when we see Coulson's stab wound.
- Confirmed, he had been dead for days until they brought him back to life.
- Jossed then confirmed! Word of God says that Mike Peterson becomes the MCU Deathlok!
- Confirmed in "The Bridge."
- It's not exactly an Extremis soldier, but they do encounter someone connected to the formula in the pilot.
- And a guy immune to the Extremis's explosion effects in episode 5. After his immunity is taken away May kills him by injecting him with an overdose that causes him to explode. Judging by Raina's plans at the end of the episode, the group will encounter more Extemis soldiers in the future.
- Confirmed in "The Bridge" when Mike Peterson temporarily joins the team.
- Confirmed. The official story is he flatlined for few minutes, faked his death and went to Tahiti (it's a magical place). Once he's out of the room, this is specifically stated to be not true. "The Bridge" ended with Reyna and Project Centipede trading Mike Peterson's son for Coulson so they can figure out what's going on with his death.
- The comics version of S.H.I.E.L.D. have flying cars in their arsenal, and it'd probably make sense for a high-ranking S.H.I.E.L.D. Agent like Coulson to have a flying car as a personal ride. It would also explain why Coulson doesn't want anyone touching his car. He doesn't want anyone messing with the car's flying capabilities.
- Item 47 also revealed a reverse-engineered Chitauri gun being mounted on a vehicle. Maybe Lola includes a hidden one.
- Confirmed. And it's the same kind of flying car Howard Stark was trying to show off in Captain America: The First Avenger.
- It is basically a Bond Car if you listen to the tech specs as described by Fitz-Simmons.Anyway, it is very much SHIELDtech.
- Confirmed - sort of. As of the second episode she seems to have been trying to get into SHIELD for Rising Tide. We will see why as the season progresses. Then we learn the real reason she joined S.H.I.E.L.D. She is looking for information about her parents, and the only clue she has now is a S.H.I.E.L.D.-redacted document from an orphanage.
- Confirmed in "The Hub". Coulson, Hand, Sitwell, Barton, and Romanov are all confirmed level 8. As for the second part, when Coulson requests to see a certain file, (his recovery report), his access denied despite being a Level 8 and he is told to make a formal request to Director Fury himself.
- In "T.A.H.I.T.I.", Director Fury is stated to be Level 10. He is also seemingly the only Level 10, since it was said that Level 10 access could only have been Fury.
- It just so happens that Episode 7 ("The Hub") did feature a few twists: Skye learning a bit more about her past, and Coulson delving into what really happened to him. Plus, the first indications that SHIELD isn't as altruistic as it seems.
- Confirmed. He didn't know before, but May tells him in "Seeds". He essentially states the above
- Kinda confirmed. In Seeds, Coulson found out the truth about Sky, she was an 0-8-4 and is implied to have unknown powers. He later tells her what he knows.
- Confirmed It doesn't happen in episode 1x11. In that one Skye is kicked off of the Bus thanks to Hand and May, the latter supporting it specifically because Skye's not an agent and can act outside protocol. It ultimately happens in episode 1x16. Then SHIELD goes defunct two episodes later and the badge is worthless.
- Confirmed.
- Partly confirmed. HYDRA, via Centipede, is after Peterson as Deathlok.
- The Winter Soldier has given this theory a lot of credibility and it's confirmed in episode 17
- Confirmed. The Slingshot doesn't exist. Anything shipped there is actually boxed up and placed in a secure vault in the Fridge.
That HYDRA is alive and well has been confirmed by Word of God with the announcement that Baron von Strucker will be a villain in the second Avengers movie. More importantly, in Captain America: The Winter Soldier, it turns out that HYDRA has infiltrated SHIELD and numerous SHIELD agents- including even Jasper Stilwell as well as Alexander Pierce, Fury's superior- are deep-cover for HYDRA. The movie also introduces Zola's algorithm, a computer program designed by Arnim Zola that basically allows you to predict the future, providing an explanation for the Clairvoyants' abilities.
- Confirmed as of Turn Turn Turn. The Centipede Group is indeed HYDRA.
- Semi-confirmed. She was given one of the drugs that Coulson was injected with during his resurrection, but didn't go through the full process.
- There's certainly a subconscious awareness of what happened; every time someone mentions his downtime in Tahiti, he says the same thing: "It's a magical place." (emphasis mine)Coulson: You should go there some time.Hill: Where's that?Coulson: Tahiti. It's a magical place.
- As of "FZZT" Confirmed, when Coulson comforts the dying firefighter he mentions he was dead and "gone" for more then 8 seconds, and assures him there is an afterlife.
- During "The Hub" he stumbles when making "It's a magical place" line, clearly catching himself saying it and recognizing there's something wrong about it.
- Confirmed. In T.A.H.I.T.I. it's revealed that the name of the facility where the procedures were done on Coulson doesn't exist.
- Confirmed. In episode 14, "T.A.H.I.T.I.," he discovers that the serum used to repair his heart was harvested from an alien's body kept in stasis.
- Confirmed. Ward frees her in “Providence”.
- Confirmed.
- Semi-confirmed. She didn’t betray him so much as abandon him in the middle of the final battle. He didn’t really care by that point.
- Confirmed, but it wasn't Loki or Thanos.
- It's been said over and over by different characters that Fury "moved heaven and earth" to bring Coulson back. That could be taken literally as well as metaphorically. Then there's that blue/green liquid that was injected into Coulson in his flashbacks. This might feed into the theory that The Clairvoyant is just someone with high level access to SHIELD records. If Fury kept the truth about Coulson's resurrection off the books, then the Clairvoyant's "powers" wouldn't be able to uncover it.
- Mostly confirmed. The serum that revived Coulson was harvested from a decomposing alien, most likely a Kree.
- In "Turn Turn Turn: following an intense Ship Tease they share a Now or Never Kiss. Then Grant's revealed to be working with HYDRA! So, confirmed?
- Depending on Raina's definition of "monsters", that might be Confirmed.
- Confirmed to a degree. It's revealed that Skye's mother was able to touch the Obelisk without ill effect, and that she did not age since Whitehall first encountered her decades before, so she's definitely either a metahuman or was exposed to something that changed her into one. It hasn't been confirmed whether her dad is similarly superhuman, but it's certainly possible, given his investigation of the Obelisk. Also, Skye was injected with GH.325, which has had ill effect on all humans(including Coulson) injected with it, with no ill effect.
- Confirmed. The first episode of season 2 "Shadows" shows that he's locked up in the Playground and Coulson uses him to uncover HYDRA secrets. As for "redemption" he insists that everything he tells Skye will be 100 percent true from now on, but no one buys that, especially Sky herself.
- Confirmed of the season 1 finale.
- A television series starring the character was also announced but has apparently been shelved since then, and it was mentioned that elements of it have been put into this TV show.
- Confirmed at SD Comic Con.
- Confirmed.
- Her actions at the end of TEOTB could be down to her thinking the team are the bad guys. Given her by-the-book ways, it wouldn't be much of a stretch if she immediately suspected rulebreakers if she came across evidence SHIELD had been infiltrated. Given she was confused at why so much effort was being expended to rescue Coulson, she might even consider that "evidence" against him ( The HYDRA controlled element want to protect one of their pawns, rather than having to risk recruiting a new one). Indeed, for all we know the entire Clairvoyant conspiracy was unrelated to HYDRA.
- The notion that Hand believes Coulson and team to be the traitors is supported by a brief argument seen between her and Simmons in the "Turn, Turn, Turn" promo:Simmons: He's a good man!Hand: He's a liar!
- Hand either thinks Coulson was a HYDRA sleeper agent the whole time or is making an excuse to turn on him similar to the ones made in regards to S.H.I.E.L.D.'s manhunt on Captain America and Black Widow.
- The notion that Hand believes Coulson and team to be the traitors is supported by a brief argument seen between her and Simmons in the "Turn, Turn, Turn" promo:
- Confirmed.
- After the events of Captain America: The Winter Soldier, SHIELD has been dissolved. Since Coulson and crew are already officially rogues, they'll continue under the SHIELD moniker as an A-Team like band, re-recruiting old SHIELD agents to their ranks.
- Confirmed. Coulson is making a new SHILED as the new Director but SHIELD's reputation is still ruined so the rest of the world will see them as such.
- Confirmed in the first season finale; Fury even promotes Coulson to director.
- Confirmed, though Simmons does all the kissing. Oddly enough, no kiss on the lips.
- Give Fitz brain damage. As good as dead, but not truly dead.
- Confirmed: Word of God has stated that it was Ward who was slated to die in the Season 1 finale, but the writers felt there was more story to tell there, so he got let off with a maiming and incarceration that allows for his potential return.
Something similar could happen with Simmons and the anti-serum derived from Chitauri antibodies.
- Partially confirmed. Coulson has started showing side effects from using the drugs similar to those shown by Garret. Skye hasn't, but she also was given the drug much more recently, so that could just mean that it will take more time before she suffers them.
- Skye is later revealed to be immune because she's Inhuman, who were created by a genetic engineering program developed by the same alien race as GH 325 was made from.
- Despite what the trailer for the next episode implies, Simmons is not a HYDRA agent. That's just another case of Superdickery. Actually, she's Nick Fury's mole. The two of them had plenty of time to talk after he rescued her and Fitz (Fitz was unconcious, so they were basically alone). It wouldn't have been hard for him to ask her to take on an undercover assignment. She'd be an ideal choice: Who'd ever suspect Simmons of pulling the wool over their eyes? With a little training from Fury, she could probably infiltrate without much trouble.
- It's equally possible is that Coulson himself sent her (without telling anyone else on the team, of course). This would really play into the whole 'willing to deceive the team and basically grow into Fury's shoes' arc that his character seems to heading down. Furthermore, it's entirely possible that her apparently joining HYDRA is to gain access to their medical intelligence to see if they have anything that can help fix Fitz.
- Confirmed in Episode 3. Everything but Fury being behind this ploy is true, including the superdickery. The "did you think I wouldn't find out?" line from the preview was Coulson scolding her for not stocking healthy food in her new place, and that was even his fault in the first place.
- It's equally possible is that Coulson himself sent her (without telling anyone else on the team, of course).

Furthermore, it's entirely possible that her apparently joining HYDRA is to gain access to their medical intelligence to see if they have anything that can help fix Fitz.
- Supported as of Ye Who Enter Here, with a music box in Sky's nightmare playing 'Daisy Bell (A Bicycle Built For Two)'.
- Confirmed in "What They Become"!
Furthermore, Kevin Feige has said that Inhumans will be set up in the MCU before their actual film. While it could be referring to the Maximoff twins in Avengers: Age of Ultron, what if it's also referring to Skye? It would make sense, and give Agents of SHIELD an opportunity to blaze a trail instead of having to play catch-up with the rest of the MCU.
Finally, Kyle MacLachlan looks a bit like Maximus the Mad.
- The Skye part is confirmed as of "What the Become", but her father is actually Mister Hyde, aka Calvin Zabo.
- Possibly Jennifer Swann
- Could be Mockingbird, a smart scientist who trains to be an Action Girl.
- Jossed. Mockingbird is a completely separate character who will be appearing in season two.
- A chance she is Mantis. "Celestial" and "Skye" are kind of similar words.
- Or she's Carmilla Black.
- She's Carina Walters, daughter of the Collector who is confirmed to exist in the Marvel Cinematic Universe due to The Stinger after Thor: The Dark World. She became a hacker to collect information much in the same way her father collects people and objects.
- Justine Hammer, daughter of Justin Hammer.
- Sasha Hammer, who is also half-white, half-Asian. Though Sasha is Justin Hammer's granddaughter in the comic universe, the Justin Hammer of the MCU is too young to be a grandfather. Sasha might be the daughter of Justin or the daughter of Justine, who might be turned into Justin's sister.
- Ms. Marvel: The comics version of Ms. Marvel (the first one, Carol Danvers), gets her powers through having her DNA mixed with the DNA of a Kree. Skye now has what might be Kree blood running through her veins. ** Probably jossed. Carol's getting her own movie in Phase 3.
- Daisy Johnson
- CONFIRMED.
- This lends credence to the theories which involve Asgard; Thor might have considered it a personal favor because of Coulson's actions in the first Thor movie and Coulson protecting Foster in The Avengers, as well as feeling responsible for the fact that it was his own brother who killed Coulson.
- He's not just a random agent of the lot, he's Nick Fury's most trusted liutenant. A culture like Thor's would understand this and grant them this favor.
- As of "The Beginning of the End" - Fury acknowledges Coulson an Avenger, and the purpose of Project Tahiti is revive a fallen Avenger.
- According to Raina, her parents were the ones trying to find her and they were the ones who killed everyone back then.
- And one of them did eventually find her.
- Confirmed.
- Confirmed sort of. It was actually the Terrigen crystals inside the Diviner.
- Confirmed, though moreso because he has several meetings with Coulson that convince him of the latter's trustworthiness.
- Confirmed. Raina explains the Kree to Skye, and later an actual Kree visits to explain the history of the Kree and the Inhumans.
- Confirmed in "Melinda": She had to take out a little girl who had mind-controlled an entire criminal group and the SHIELD agents sent in to rescue her. The little girl also knocked out all of her puppets while trying to control May, which made the agents think that she had taken out thirty or so men while they were out.
- Confirmed, Coulson kills him in the winter finale. The question of who will take his place within HYDRA (And as Big Bad, which might not be the same thing) has yet to be answered.
- Tentatively confirmed, pending further evidence, or at least Morse and Mack believe it's the "real S.H.I.E.L.D.". Who exactly is behind it — whether it's Hill (who may not even know Coulson is the Director) or Stark Industries or some other group — still remains to be seen.
- Totally confirmed in the ensuing episodes.
- Corollary to this: with the reveal in "The Writing On The Wall" that the alien writing is a 3D map of a city, it's a good chance this special city is Attilan, home of the Inhumans (and yes, several thousand years old).
- Further supported by "The Things We Bury". According to legend, blue aliens came to Earth in ancient times, and they brought an artifact called the Diviner. The writings on the Diviner are the same that Garrett, Coulson and the other T.A.H.I.T.I. subjects have been making, which have been all but confirmed as Kree language. Much later, a dead Kree was harvested by SHIELD to create the T.A.H.I.T.I. drug. Everyone who touched the Diviner was killed immediately, except for one young woman who was granted immortality instead. And that woman's daughter remains the only person to be exposed to the T.A.H.I.T.I. drug with no side effects. It's getting easier and easier to conclude that the Kree brought an artifact to Earth that created the first Inhumans.
- Confirmed
- He's a Senator when we meet him, and refuses to confirm the things Ward accuses him of. Eventually he admits it to him, but he regrets what he did.
- The cellist was mentioned by Coulson to Ward in "The Bridge". She thinks he's dead.
- The Cellist (aka Audrey, played by Amy Acker) plays a central role in "The Only Light in the Darkness".
- Alternatively, he may attempt to rejoin HYDRA but they will not allow it, given that he's spilled too many HYDRA secrets to S.H.I.E.L.D. while being their prisoner. In this case, HYDRA will at best shoo him away and at worst try to kill him.
- Finally, he may rejoin HYDRA, but as The Mole—he will ultimately reveal himself in a truly heroic action, thus indeed proving his sincerity to Coulson's team that he wants to atone.
- He does join HYDRA near the midseason finale, but it does turn out he has ulterior motives - namely, finding Skye. Later in the series he does teams up with Coulson to help take down HYDRA, so parts of all these are confirmed.
- Confirmed, though it's not a hard search - he simply joins HYDRA again, who are already working with Cal.
- Confirmed in "Melinda", where Lincoln realizes that she's Dreaming of Things to Come.
- "Nothing Personal" builds on this with lots of talk about her being a "weakness".
- Confirmed in "What They Become". He's so eager to help Skye reunite with her father that he's completely surprised when she shoots him in the gut. He lives, but is mostly screwed over and is totally over their relationship.
- Confirmed. But since Garrett is now dead, Ward is on his own. Likely HYDRA learns of this, and will force Ward to work for them against his will as a consolation for Garrett's betrayal.
- In season 2 "Shadows" he's willing to tell Coulson any kind of HYDRA secret he wants, but only if Skye is the one asking.
- Confirmed.
- Confirmed, though Christian isn't as psychotic when we meet him.
- Confirmed
- Confirmed, but it's taken by "real" S.H.I.E.L.D. rather than Team Coulson.
- Wait, what? The Iliad is a conventional carrier, not an airship. The original Helicarrier has still not been seen or mentioned in any capacity.
- Confirmed.
- Confirmed. As of the following episode he definitely knows that they're up to something, though it appears he doesn't know what. He ultimately becomes the first one to find out the truth, because Mack kidnaps him when he presses too hard.
- Confirmed. It's mentioned that Skye and Raina are the first Inhumans to undergo Terrigenesis via the temple in a very long time.
- Confirmed
- Confirmed
- So far, Simmons has pretended to join them.
- And May as well, though she is still clearly in support of Coulson.
- Confirmed!
- Confirmed!
- Confirmed! And there's more to that as well!
- Jossed. He dies in 3x10:Maveth, though his body is still moving around under It's control.
- Actually confirmed, Ward is dead. The entity even spoke of taking dead bodies. Ward is dead, what is walking around is the entity wearing Ward's corpse.
- It's part-Jossed, part-confirmed. Ward was Killed Off for Real and taken over by Hive, but it wasn't in 3x09.
- Jossed.
- Un-Jossed as of "Watchdogs".
- The Howling Commandos (either the descendants of the original team or the modern "monster" team version)
- Confirmed, at least partially: Agent Triplett is the grandson of a Howling Commando.
- Jim Morita and Dum Dum Dugan appear in a flashback in the season 2 premiere, alongside Peggy Carter.
- Ghost Rider is summoned whenever innocent blood is shed. Both HYDRA and S.H.I.E.L.D. have shed innocent blood. Imagine Grant Ward's reaction to the Pennace Stare!
- Confirmed for season four! We'll be getting the Robbie Reyes incarnation.
- In "Lockup", the paraphernalia in the basement of the one who hid the Darkhold hints that Johnny Blaze exists.
- It was also shown in "The Good Samaritan" that another Ghost Rider gave Robbie the powers of a Ghost Rider. It is implied that he was Johnny Blaze.
Villains:'
- It's been confirmed that Franklin Hall, better known as Graviton, will be a recurring character. However, we don't know if he'll be a villain or if he'll get his powers, which would likely be murder on the SFX budget.
- He does appear as a villain, but his name is General Talbot instead of Franklin Hall.
- Madame Hydra
- Confirmed, as a Composite Character with Aida.
- According to Raina, Skye's parents wiped out the village in China where she was found by SHIELD. It's possible.
- Sort of. Skye's mother was a leader among the Inhumans and her father sees nothing wrong with activating all the Inhumans in the world at the cost of everyone else's lives.
- Confirmed by "Scars" and "S.O.S.", in which Jiaying engineers a war with SHIELD, with the intention to mkill everyone who stands in the way of her revolution. Inhumans' easy access to Diviners means they do have that capability.
- She has found her parents now. However, it won't be their last name. Because of Disney's acquisition in a galaxy far far away, she'll be Agent Walker.
- Confirmed. The name "Daisy Johnson" is evidently growing on her.
- Confirmed. In "Scars", the two organizations merge; Coulson will be the director of both with the "Real" S.H.I.E.L.D's council becoming an advisory board similar to the World Security Council that Fury reported to.
- Confirmed. Lash's powers are indeed the only ones capable of destroying HIVE's assimilation ability, and can even reverse the effect in an Inhuman under thrall.
- Limb confirmed. As for special features, we'll find out. Though it is detachable from what we can tell.
- Confirmed.
- It's focused on the Royal family, but still confirmed.
