Summary

TheMarvel Cinematic Universehas a informal relationship with the original Marvel Comics , often completely ignoring them and re - inventing characters and consequence to suit their own needs . Being based off of the historically successful Marvel Comics , it seems as though the MCU should need to strive for accuracy to the source material whenever possible . In reality , even thebest MCU moviesoften make some level of deviation from the comics , if not outright eschewing them in party favor of an original tale .

There are several reasons Marvel Studios is oftentimes very justified in make huge changes to the comic storyline they adapt . Sometimes , legal situations regarding the right of sure character , like The Hulk or the X - Men , have restrained them in the past times , take the limelight away from these hero if not veto them on the whole . Other times , the MCU is too beholden to its previous films , only able to juggle so much with the limited filmography ofeach Marvel phase angle .

10The Mandarin In Iron Man 3

A fakeout that many fans didn’t find amusing

Though they have n’t incisively crossed paths in the MCU , the Mandarin is one of Iron Man ’s most ill-famed archenemies in the comics , using his magic ten rings of power to foil the technological artistry of Tony Stark ’s suit . While the Ten Rings terrorist governing body hinted at the warlord ’s existence in the firstIron Man , the scoundrel himself had not even the faint hint of an appearance . Finally , inIron Man 3 , it seemed as though the Mandarin would in conclusion come to life within the MCU .

As it turn out , the tough Mandarin plaguing Tony Stark in the third installment of theIron Mantrilogy would wrench out to be a paid actor , but impersonating the actual figure as a panic manoeuvre . This dashing hopes was only compound by the tangible Mandarin ’s coming into court , and demise , inShang - Chi and the Legend of the Ten Rings , following Tony Stark ’s own demise within the MCU timeline . It ’s an gross tragedy that die hard mirthful fans never got to see Iron Man and the Mandarin duke it out in a big - budget movie .

9Hawkeye’s Secret Family

Hawkeye is a family man rather than a ladies' man

Hawkeye is celebrated among the original Avengers squad for being the only founding member to have something of a normal family . InAvengers : Age of Ultron , the MCU revealed that the dashing archer actually had a loving wife and small fry sequestered away on a secret farm in the distant country , kept in a sort of witness protection by S.H.I.E.L.D. Hawkeye ’s family would go on to be a Brobdingnagian crux of the matter of his story in his eponymic Disney+ serial publication , in which his devotion to them is really highlighted .

Meanwhile , the Hawkeye of the funnies has a very dissimilar love life sentence .

8Scarlet Witch & Quicksilver’s Backstory

From mutants to experiments

The one yoke of superpowered anti - heroes that manage to escape the clutches of the mutant world were Scarlet Witch and Quicksilver , being in a legal gray-headed arena thanks to being equally associated with the X - Men and the Avengers . This explain why Fox ’s X - Men movies also featured a variation of Quicksilver , a full - fledged sport who steal the show in every scenery he pops up in .

Meanwhile , Avengers : eld of Ultronintroduced the Maximoff sib as citizen of Sokovia who volunteer for experimentation at the hand of HYDRA , granting them their powers via pic to Infinity Stone . InWandaVision , it ’s revealed that Scarlet Witch really had latent magical power as a sorceress that were merely activated and enhanced by the Infinity Stone . Though someMCU characters have been confirmed as mutantsretroactively , it does n’t seem as though the Maximoff twins will be revert to their old inheritance as Magneto ’s children any metre soon .

In the comics , Pepper , Tony , and Happy are actually three points of a complicated love triangle , with both of the men gunning for Pepper at various points in time . The ultimate " winner " of Potts ' fondness does seem to finally be Tony , but there is an argumentation to be made that he is merely the consolation loot after Pepper and Happy ’s marriage cash in one’s chips in the south .

6Thanos' Motivation

From courting death to a strange ethos of resource management

The number ofdifferences betweenAvengers : Infinity Warand the comicit was based off of , The Infinity Gauntlet , is a big enough subject to be worthy of its own discourse . The single most far-famed difference , however , may just be Thanos ' motivation for wiping out half of all life in the first place . In the picture show , Thanos move on at length about his unusual idea for resource storage allocation , in which the universe ’s imagination can only be divvy up if the population is every which way pick with oecumenical race murder .

Meanwhile , Thanos ' motivation for causing so much death in the comedian are much more emotional . Instead of feigning an interest in the well - being of the universe ’s denizens , Thanos simply want to imprint the genuine incarnation of Death in the Marvel Comics , take the form of a beautiful cleaning woman . This may have been too foreign an angle for even the MCU to take when it add up to their most terrifying villain ever conceptualise , but either way , Thanos ' own ego is the rightful reason behind his wanton mass execution , no matter what excuse he may attempt to supply .

5Hank Pym Was An Original Avenger

The original Ant-Man was supposed to be far more important

In the funnies , it ’s Pym himself who introduce Ant - Man to the adventures , partaking in multitudes of missionary station with the original Avengers lineup before eventually passing the rubric on to Scott Lang . He was also renowned for being one of the minds behind Ultron , rather than the rogue A.I. being the brainchild of Dr. Bruce Banner and Tony Stark . Pym ’s gruff and arrogant personality from the comics did survive inviolate , however , meaning Paul Rudd ’s sorcerous Scott Lang was likely the skillful selection to carry the persona of Ant - Man .

4Civil War’s Inciting Incident Was Completely Different

The Sokovia Accords are an MCU invention

call after the groundbreakingCivil Warcomic tend that become one of the most iconic storylines in Marvel story , Captain America : Civil Wardid what it could within the linguistic context of Phase 3 of the MCU . The movie version of the conflict revolve about around the wipeout due to Ultron in the pervious team - up moving-picture show , Avengers : Age of Ultron . The resulting Sokovia Accords give the superhero team with a split , only deepened by the machinations of Baron Zemo .

In the comics , the Sokovia Accords was instead the Superhero Registration Act , a exchangeable lawmaking that required the capitulation of all secret identity and outlawed all non - government - sanction hero study . The Superhero Registration Act was create after a disastrous battle between the immature superhero team the New Warriors and a cell of minor villain resulted in the death of over 600 civilians . The MCU had n’t yet had the time to set up as many characters as theCivil Warcrossover laughable featured , make this change a sane one .

3World War Hulk Was Hardly Hinted At

One of the most climactic battles in Marvel history never happened in the MCU

The Avengers always had to walk on shell around the Hulk , and the tenseness around this reality came to a boiling point in the iconicWorld War Hulkstoryline . After being take for too slap-up a surety scourge and relegate to quad by the Illuminati , Bruce Banner ’s creative thinker becomes subsumed by the Hulk ’s , who start on to become a warlord in space . Returning to Earth to seek retaliation , Hulk ’s resulting violent disorder goes on to imperil the entire satellite .

In the MCU , only glimpses of this amazing storyline are exhibit . Rather than bebanished into space by the Illuminati , Bruce Banner abscond in the Quinjet on his own volition , though he does still get on Sakaar to become a beloved figure among the alien crowd . Korg and Miek , two of Hulk ’s most trusted alien generals , also appear in the MCU , though as favorable wise - cracking shadow of their bloodthirsty original selves . It ’s an utter shame that the MCU never get to explore a final showdown between a hyper - powered Hulk and the Earth ’s heroes .

2The Hulk’s Origin Is Completely Different

Rick Jones has yet to make an appearance in the MCU

Hulk ’s story within the Marvel Cinematic Universe has been repeatedly hurt by the studio apartment ’s unfitness to centre on the character for more than a single solo film .

In the MCU , Dr. Bruce Banner volunteer for one of many experimentation assay to copy Dr. Erskine ’s super soldier serum used on Captain America , substituting vita radiation therapy for gamma radiation and inadvertently make the Hulk .

In the comics , Dr. Banner was actually exposed to a deadly dose of radiation in a freak accident at a atomic dud testing cooking stove . In an effort to get Rick Jones , a random teenager who had bumble into the dangerous test site , out of the way , Dr. Banner meander up getting strike by a powerful blast from the experimental bomb calorimeter , produce the Hulk . It ’s a shame that the MCU ’s revised Hulk descent imply that Rick Jones has n’t been present in the MCU , as the character ends up gaining his own monstrous shift as A - Bomb .

1Thor’s Secret Identity Was Glossed Over

The MCU wasn’t fond of Dr. Donald Blake

Much like his first appearance in the MCU , Thor ’s origin in the comics begins with him being cast down to Earth by Odin , being hold ugly of Mjolnir until he can show himself . What the Marvel Cinematic Universe leaves out is the fact that Odin also erased Thor ’s retentivity in his original origin , making him conceive himself to be Dr. Donald Blake , a medical doctor . When he eventually discovers his Asgardian heritage , Dr. Blake is capable to metamorphose into Thor to fight offence on Earth , disguise his pounding as a simple walk cane .

The MCU movies only barely gloss over the Dr. Donald Blake persona , never have Thor turn a loss his memories or assume much of a human disguise . He briefly wear the identity of Dr. Blake , revealed to be a separate person who used to date Jane Foster , to sneak out of custody , but the name never comes up again in thesubsequentThormovies . TheMarvel Cinematic Universeseems to have a particular disdain for secret identities in general for its major characters , and Dr. Donald Blake was no elision .
