TheMarvel Cinematic Universeis full of wasted electric potential , with hordes of characters being introduced only to not be decent utilized . Thestrength of MCU moviesis carried mostly by their character , with bombastic personalities and stark cast being a big majority of the rationality to watch a Marvel movie in the first place . unluckily , the franchise is quite notorious for introducing interesting new characters only to consume their potential .

In finicky , Marvel has a infamous villain problem , in which interesting newfangled opponent are introduced and kill off within the same movie without getting proper filmdom time or maturation . In late yr , the franchise has also began slacking in insert new post - Avengers : Endgamecharacters only to leave them to pine away in obscureness for far longer than was done previously . Whatever the showcase , Marvel movies are a graveyard of waste on - screen potential .

10Ultron

Avengers: Age of Ultron

By far the loose character to sharpen to when it comes to specifying villains that require a big place in the MCU is the killer robot Ultron . Introduced in his eponymic movieAvengers : Age of Ultron , the murderous A.I. quickly becomes one of the biggest threats ever to front The Avengers , bring with him plenty of potential drop for fascinate story . Sadly , Ultron is killed by his heir , Vision , within the same film he ’s introduced in .

Joss Whedon clarify the ' Age of Ultron ' claim of ' The Avengers 2 ' and confirms that Hank Pym ( Ant - Man ) will not be in the film .

Going by his grandness to the comics , Ultron merit to be an overarching multi - movie scoundrel on the same story as Thanos . James Spader is also excellent as the part , conveying a cold indifference to humanity and psychotic belief of grandeur with his dulcet tones . Hopefully , Ultron ’s return in the upcoming Vision seriescan fulfill the prophesy of a terrific villain he should ’ve carry out from the beginning .

9Quicksilver

Ultron himself was n’t the only character to be premise and killed off in the same plastic film despite having oodles of promise within the series . Enter Pietro Maximoff , a.k.a . Quicksilver , the Infinity - Oliver Stone - enhanced speedster that go circles around The Avengers in his unveiling . As fast as he is , Pietro ultimately is n’t able to outrun some bullet fired by an Ultron pilotless aircraft when saving the lives of Hawkeye and a random child , giving him a awfully anticlimactical last .

This edition of Quicksilver was teased to enter the MCU inWandaVision , only for the role to once again fall apart under the reveal as the pretense of a lame , juvenile joke .

TheX - Menprequel cinema demonstrated the potential of Quicksilver far comfortably , giving him an entertaining activity collage utilizing his first-rate speed two film in a row . As if to add insult to combat injury , this version of Quicksilver was ride to enter the MCU inWandaVision , only for the type to once again crumble under the reveal as the pretense of a lame , puerile joke . consider how authoritative his sister ended up being , it ’s a disgrace Quicksilver could n’t stick around longer in the serial publication .

8Shang-Chi

Shang-Chi and the Legend of the Ten Rings

In 2021,the Marvel Cinematic Universe added a valuable new Hero of Alexandria inShang - Chi and the Legend of the Ten Rings , the titular martial artist submarine . In the movie , Shang - Chi finds the secret realm of Ta Lo , confronting his father , the immortal warlord Mandarin , and freeing the city from the influence of the evil Dweller - In - Darkness . InShang - Chi ’s post - credits tantrum , he ’s colloquially inducted into The Avengers by Wong , Captain Marvel , and Bruce Banner , the latter of whom tell him " Welcome to the carnival . "

Yet , over three years since his flick debut , Shang - Chi has yet to make a second true appearance in the Marvel Cinematic Universe . Compared to similar entrant Black Panther in 2018 , who also added some worthful representation to the MCU spue while introducing a whole novel vista of the worldbuilding , Shang - Chi has been far slower in reappearing in a crossover event . This lack of presence is often cited as evidence of the MCU ’s want of planning after the Infinity Saga .

7Doctor Samuel Sterns

The Incredible Hulk

One of the oldest Marvel Cinematic Universe teases that has still yet to pay off after over 15 years , Dr. Samuel Sterns inThe Incredible Hulkis one of the series ' cock-a-hoop unresolved plot thread . The film ends with the cellular life scientist being regard by Bruce Banner ’s gamma - infused blood entering a wounding on his head , increasing his genial capacity dramatically at the price of strain his head . This obvious solidifying - up would see Samuel Sterns become the classic Hulk baddie from the comics , The Leader , who is the brains to The Hulk ’s brawn .

Since his last live - natural process pic appearance , Sterns has only made an appearance in the obscure affiliation - in comedian .

Even there , he does n’t do much , being catch by Black Widow and placed in S.H.I.E.L.D. custody . Allegedly , Sterns will finally make his grand homecoming inCaptain America : Brave New World , but between Red Hulk and Sidewinder , it ’s improbable that The Leader will have much time to wear the villainous mastermind role he deserve .

6The Scorpion

Spider-Man: Homecoming

Teasing appearing from future villains was n’t a riding habit the Marvel Cinematic Universe uprise out of in Phase One . In the post - credits conniption ofSpider - Man : Homecoming , Michael Keaton ’s Vulture is approached in prison by a marred convict asking for Spider - Man ’s secret identity element , only for Toomes to show a variety of heart and protect Peter Parker ’s life . The captive was none other than Mac Gargan , a.k.a . The Scorpion , play by Michael Mando ofFar Cry 3andBetter Call Saulfame .

The fact that a unique Spider - Man baddie was tantalize so ahead of time on only to be dodged two solo movies in a row is incredibly unknown , begging the question as to whySpider - military man : Homecomingeven bothered with the scene in the first plaza . It would ’ve been interesting to see how Mac Gargan oppose to Spider - Man ’s identity element becoming public knowledge at the end ofSpider - Man : Far From Home . Sadly , Michael Mando ’s Scorpionseems to remain yet another unresolved villain mystifier .

5Jane Foster

Thor: Love and Thunder

By many accounts , Thor : Love and Thunderis a very blemished film , with comedy that does n’t land , a wasted molding in Christian Bale as Gorr the God - Butcher , and some painfully poor CGI effects . If there ’s one vista of the film that really act , however , it ’s the reintroduction of Jane Foster as The Mighty Thor , being chosen by the shatter Mjölnir to be the next hero worthy of wielding Thor ’s power .

surrogate succumbs to her Crab diagnosing inThor : Love and Thunder , the film introduce a cool new hero with history in the franchise only to cruelly rip her away .

consider Thor has for good moved away from Earth in the MCU , living off - satellite to rear Love by himself , Jane Foster would be sodding as his functional substitution as a hero on Earth . This would even mirror The Mighty Thor ’s comic unveiling , hold on Thor ’s legacy as a new Avenger . deplorably , Foster succumbs to her cancer diagnosing inThor : Love and Thunder , the motion-picture show introducing a coolheaded new hero with history in the franchise only to cruelly rend her aside .

4Ulysses Klaue

Black Panther

One of the most underrated villains in the Marvel Cinematic Universe is Andy Serkis ' Ulysses Klaue . Being a riff , if not an exact version , of the definitive Black Panther villain from the comics , Klaw , Ulysses Klaue is a dastardly Vibranium stealer who is cursed with a bionic weapon for his trouble , experience into multiple clashes with Black Panther and The Avengers . Andy Serkis plays the unabashedly evil villain with such whimsy and glee that it ’s unsufferable not to enjoy his on - filmdom presence .

Sadly , Klaue is unceremoniously killed by Erik Killmonger inBlack Panther . While he also dies in the comics , Klaw is resurrected to become a genuinely power villain with a dead body made of double-dyed audio , whose unique status get him to become a weirdly important part of theSecret Warscrossover comedian . ConsideringAvengers : Secret Warsis on the purview , it ’s a shame the MCU never took the luck to memorialize him in the same way .

3The Warriors Three

Thor

Thor ’s move forth from the Shakespearian fantasy dramatic play of Asgard and into the cosmic realm of Marvel ’s wider Galax urceolata inThor : Ragnaroksadly left a few fascinating characters in the original out to dry out in the tale . Namely , Lady Sif and The Warriors Three , Thor ’s best champion and pal - in - arms in the defence force of Asgard . Some of the most dress and deadly Asgardian warrior , the trio is made up of Hogun the Grim , Fandral the Dashing , and Volstagg the Svelte .

The Warriors Three are distinct personalities that each specialize in a unique shape of mediaeval weapons system , making them fun characters for Thor to take on off of . Sadly , their family relationship is n’t search much in any individualThormovie before they ’re unceremoniously down off by Hela inThor : Ragnarok . It would ’ve been great to see a crony - cop style risky venture motion picture with Thor pass more time developing his bond with the three of them , not to cite Lady Sif .

2Goliath

Ant-Man and the Wasp

TheAnt - Manmovies have slowly introduced more and more characters capable of wieldingHank Pym ’s specialty engineering , from his daughter Hope , the next white Anglo-Saxon Protestant , to Cassie Lang , Scott ’s girl aged 5 long time in the blip . One interesting figure that does n’t get more meter is Laurence Fishburne ’s Bill Foster , a former lab partner of Hank’s . Foster was the first to prove the giant - sized applications of Pym Particles on people , though Scott quickly smashes his former phonograph record inCaptain America : Civil War .

In the comics , Bill Foster is a superhero all of his own , Goliath , who specializes in becoming a titan - sized fighter . The MCU only shortly explore this possibility briefly in theWhat If … ?episode , What If … Peter Quill Attacked Earth ’s Mightiest Heroes ? , in which a younger Bill Foster actually takes on the mantlepiece of Goliath . Even if Laurence Fishburne ’s age is a limiting factor in making him an active superhero , if Hank Pym can participate in the action inAnt - Man and the Wasp : Quantumania , so too should Bill Foster .

1The Eternals

Eternals

Sometimes , the Marvel Cinematic Universe will not only miss out on the opportunity give by a newfangled type , but an integral Modern cast . Enter the Eternals , a subspecies of superheroes sent to Earth to protect humanity for eons as sentient life developed , guard them from the predatory Deviants . Though their absence in early films had to be explained away , the Eternals actually end up being some of the most significant fibre to the lore of MCU ’s Earth , being key to humanity ’s survival in the gaze of Arishem the Judge .

Much like Shang - Chi , the Eternals have been strangely absent following their launching for a few geezerhood now , with most of them being shipped off into space by the end of their feature flick . Even ifEternalswasn’t the strike impinge on Marvel Studios think it to be , the immortal defender of humankind should ’ve come back into play at least once by now . Hopefully the future of theMarvel Cinematic Universehas some kind of place for these divine super - powered beingness .
