At this year ’s San Diego Comic - Con , Marvel Studios made headline with a number of pregnant reveals about the time to come of the Marvel Cinematic Universe . Among the most exciting things we learned is that 2019’sCaptain Marvelwill orchestra pit Brie Larson ’s title eccentric and her ally against the nefarious alien backwash , the Skrulls . First insert in   1961’sFantastic Four # 2,the Skrullsrecently ( well , 9 geezerhood ago ) wreaked havoc throughout the Marvel Universe in   2008 ’s crossover event , Secret Invasion . During that arc , they used their shapeshifting and power - mimic abilities to strategically nobble and take the topographic point of several outstanding Marvel characters in an attempt to destabilize the various defenses of Earth until it was mature for the taking .

With the Skrulls ' impending cinematic debut , it would n’t be surprising if the   MCU start to lay the foot for a magnanimous - screen Secret Invasion , bring out that not every hero ( or villain ) we ’ve come to know and lie with is who they seem . Read on for the 15 MCU characters who could really be Skrulls in camouflage !

Captain Marvel

Carol Danvers is one of the most redoubtable sub in the Marvel Universe , thanks to her altered genetical computer code that makes her much half - Kree ( the same coinage as Ronan , the villain inGuardians of the Galaxy ) . She is equal to of flight , has topnotch - strength comparable to Thor and Hulk , and can absorb massive sum of energy and airt it through concussive photonic blasts from her hand . That kind of major power seems like it would have been quite useful against the Chitauri and Ultron …

Now that Marvel has announced thatNick Fury will be fighting alongside Carolin her solo movie , whichtakes station in the 1990s , one has to inquire why he did n’t call on her when he first begin the Avengers Initiative , and where she ’s been for the last 20 - queer long time . Does she in fact make it through the events of her picture show unscathed , or has she been a prisoner of the Skrulls this whole prison term ? It could be that the Carol the team is   sure to meet inAvengers 4is not the literal Captain Marvel at all .

Tony Stark

This one could be a longshot ( what are the betting odds Robert Downey , Jr. go for to playing a villain after all this fourth dimension ? ) , but there is a case to be made that some   of Tony Stark ’s action since he bring together The Avengers have been , at best , reckless , andat worst , evidently destructive .

His existence of Ultron , which at the clip he claimed was to ensure that the world had protection if The Avengers could no longer provide it , nearly brought about the end of the human race . But what if that   was an intended   feature rather than a bug ? What if Tony was abducted at some stop during or afterThe Avengersand his imposter has been planting seeds of discordance ever since ? Again , as Tony has been the gumption of the MCU since its inception , it would be a pretty unlikely act of events to have him debunk as an enemy , but the opening of the narration intestine - puncher of such a reveal is too much to ignore .

Hank Pym

The formerAnt - Manshould be considered on any list of possible Skrull impostors if for no other cause than that he was abducted and replace in the comic book storyline . While it ’s honest that the big - screen version of Hank Pym has played a far less large role in the Marvel Universe thus far than the Pym we get laid from the comics , that does n’t think of he wo n’t run across the same fate in anySecret Invasionadaptation .

Like in the comics , the MCU ’s Pym has a farseeing chronicle of scientific contributions between his time with S.H.I.E.L.D. and his society , Pym Technologies . A man with those imagination is a valuable asset for a strength with aims on invasion . Though his expulsion as chief operating officer of the company he lead off would sure prove to be an obstacle , he ( or something posing as him ) could be on the way   to recover his standing   through his employment with Ant - Man and Wasp .

Black Widow

During the events ofSecret Invasion , we discover that Spider - Woman , a sure member of the Avengers and S.H.I.E.L.D. , has in fact been replaced at some point in the yesteryear by the Skrull queen , and that she ’s   been working against the heroes for a class or more . It ’s a shameful reveal , and while Jessica Drew has not yet been introduce in the MCU , the filmmakers could elect to have her role in the tale filled by Natasha Romanov instead .

Black Widow has been a stalwart of the Avengers since the start , and she has commonly been the vocalism of reason when other Avengers begin to recede their way .   For our heroes to learn that she has been replaced by a creature compulsive to put more " red in the ledger " would be a truly withering   import .

Pepper Potts

Tony Stark and Pepper Potts have a long and complicated relationship . Pepper was the first one to determine of Tony ’s extracurricular activities , and despite her better judging much of the clip , she has affirm and protected him throughout his tenure   as Iron Man .

But things have not always been smooth gliding for the couple . Pepper almost decease at the bridge player of Aldrich Killian and his Extremis computer virus inIron Man 3 , which may have put up to the fall out Tony acknowledgment to Steve Rogers inCaptain America : Civil War . unknown it seems , then , that the next clock time Pepper appears on cover , at the death ofSpider - Man : Homecoming , she and Tony are at a high point in their relationship , with even talk of an engagement being bandy about .

Now , it very well could be that Pepper reconcile with Tony entirely of her own agreement ( it ’s been know to happen ! ) . But perhaps the Skrulls agnize that Tony ’s affection for Pepper could be used against him , and they have positioned one of their own to be by his side , quick to backstab him or steer him towards their villainous goals at a second ’s notice .

How Rachel Zegler’s

Thaddeus “Thunderbolt” Ross

BeforeCaptain America : Civil War , the last clock time we had see General Thunderbolt Ross , he was a defeated world , having made an Abomination - sized misunderstanding in his obsessional quest to take down Bruce Banner and his green - skinned alter ego . It ’s quite the turnaround indeed to go from the architect of the destruction of Harlem to U.S. Secretary of State .

It makes one wonder what exactly the general did to mend his certainly damaged stand to the item that he ’d be confide with a cabinet position . Did he in fact take his monstrous loser inThe unbelievable Hulkand apply it as motive to mount the government run ? Or was he prey upon at his lowest instant by an opportunistic specie and replaced by a more expertly manipulative creature than him ? There ’s got to be more behind the reversion than that cast-off golf game story he name inCivil War .

Phil Coulson

Phil Coulson was one of the first threads to begin tying the separate entry in the MCU together . His appearances inIron ManandThorintroduced the moviegoing world to the Strategic Homeland Intervention , Enforcement , and Logistics Division , and his demise inThe Avengersproved to be the accelerator that helped the heroes lick as a team . As we all know , though , dying in comic books is more of an inconvenience than anything else , and so it was for Agent Coulson , as he has been back covertly running S.H.I.E.L.D. for four season now .

But how can we know for sure that Coulson ever came back from the dead at all ? True , Agents of S.H.I.E.L.D.has allow for some detail regarding his resurrection , but the theory of a retcon , that good old - fashioned mirthful book trope , can never be usher out . Plus , having Coulson , Director of S.H.I.E.L.D. , revealed as a Skrull in the track - up to Secret Invasion in Phase 4 would be the perfect way to draw Marvel tv set back in with the film .

Sharon Carter

As we get a line inCaptain America : Civil War , Sharon is the slap-up niece of S.H.I.E.L.D. carbon monoxide gas - founding father and Cap ’s first passion , Peggy Carter . If the Skrulls are deserving their salt as intergalactic conqueror , they will have had their eye on Earth for quite a while in cooking - long enough to realise both the scourge and the economic value Peggy and S.H.I.E.L.D. itself pose to their goals .

penetrate her family and her organization would guarantee a tactical advantage , as Sharon has access to people and information vital to the defending team of Earth . That reward has turn even stronger now   that   Steve Rogers has recently developed feelings for Sharon , leaving one of the most powerful and influential hoagie on the planet - particularly once he is no longer viewed as a warfare criminal - vulnerable to use as the Skrull invasion nears .

Maria Hill

The most dependable friend of Nick Fury ( more on him afterwards ) , former S.H.I.E.L.D. Deputy Director Maria Hill has play a substantial persona in monitoring and eliminating terror like the Chitauri encroachment . Hill ’s loyalty to Fury has also poke out beyond her time at S.H.I.E.L.D. , leading her to puzzle out close with ( or perhaps gather intel on )   Fury ’s inspiration , The Avengers . After HYDRA ’s infiltration cause the precipitation of S.H.I.E.L.D. , she dedicated herself to working alongside the super - squad rather than for the governance she used to serve well .

With all that tell , Hill ( along with her wise man ) was conspicuously absent from the events ofCaptain America : Civil War , beg the question of whether she was in fact cognitive content to watch the team splinter from a distance as she worked towards a more nefarious endgame .

Heimdall

One thing to remember is that the Skrulls - at least as we know them in the comic - have been around threatening civilizations like the Kree for millennium . The same can be said for our friends the Asgardians , and it is only possible that they have confronted a Skrull invasion themselves . What if , upon   failing to conquer Asgard at some point in the yesteryear , the Skrulls just elected to use a sealed all - see to it , Bifrost - guarding Asgardian as a mean value to seek out other , more susceptible worlds ?

Before the Bifrost Bridge was destroy during the events of the firstThor , Heimdall had all the time in the world to gather info on the Nine Realms and relay back to his home macrocosm that Midgard in particular , with its war nations and unstable alliances , is a prime prospect for occupation . On a more straightforward note , Heimdall ’s for sure sporting a different looking at inThor : Ragnarokthan anything we ’ve seen previously .
