The best voice of any superheromovieare usually the fight scenes . This is when good triumphs over evilness or , if the film maker want to didder things up a bit , evil kick good ’s ass . However , things are a small routine more complicated in theMarvel Cinematic Universe , as the type have a habit of switching sides and motivation fairly frequently .

This often makes for excellent drama and higher bet as it throws the audience for a loop and asks them to carry the unexpected . When this is done well , it ’s fantastic . However , there have been occasions within theMCUwhere some rivalries just make no sense whatsoever .

Best - The Winter Soldier And The Falcon

interview only really get to see these two characters interact properly with each other inCaptain America : Civil War , as before then , Bucky ' die ' in the past during World War II , and then reappeared in the present but was being brainwashed by HYDRA .

The first timeSam and Buckyofficially met , they did n’t get off to a great head start . Sam did n’t really like Bucky because he was a killer and had tried to kill Sam and Steve multiple times . Bucky did n’t like Sam because … really we do n’t know . mayhap he was jealous . Although their little rivalry did n’t last long , it was very entertaining to check .

Worst - Peter Parker And Flash Thompson

In thecomics , the contention between Peter Parker and Flash Thompson is almost legendary . The otherSpider - Manfilm franchises released before the Sony / Disney deal even made sure to make Flash as big a douche bag as possible to think over Peter ’s diminish in high spirits shoal popularity ( while at the same time pinch some outdated cliches in there as well ) .

However , the most late Spider - Man moving-picture show series take part in theMCUhas almost skipped out on this competition in all . In candor , it was never really part of the primary plot but it has foreshorten Flash ’s character to something whole rather senseless .

Best - Quicksilver And Hawkeye

Although this competition only lasted for one movie , it was kind of cute and endearing to watch . It was also jolly funny . They first encountered each other during the Avengers ' foray on the HYDRA understructure for retrieve Loki ’s sceptre . The wand had been used to give Quicksilver and Scarlett Witch their newfound ability .

Quicksilver used his speed to run ring around Hawkeye which resulted in the latter being shell by a lazer cannon . Their tit - for - tat rivalry continued throughoutAge Of Ultronuntil Quicksilver altruistically sacrificed his life to save Hawkeye from a hail of bullet .

Worst - Captain America And The Winter Soldier

Steve Rogers and Bucky Barnes were best friends back in the 1940s during the Second World War . In fact , they were much inseparable . Unfortunately , Bucky joined the warfare exertion and Steve was pull up stakes behind because he was too skinny , or something along those lines . Thanks to the tops soldier serum though , Steve was able to do his bit .

During the war , Bucky was apparently killed on a mission , devastating Steve . However , Bucky returned in 2014 as the Winter Soldier , brainwash by HYDRA . This set him on a collision course with his former champion but it was never really a rivalry as Bucky was n’t playact of his own volition .

Best - Nebula And Gamora

TheMCUreally knows how to portray sibling rivalries at their finest , and one such object lesson is the tension between the two adopted sisters , Nebula and Gamora . Though not related , or even the same species , Nebula and Gamora grew up together under the abusive centre of the Mad Titan , Thanos himself .

Thanos being unhinged , he always mark the two sisters against each other , rewarding the victor and punishing the loser . This was where all Nebula ’s hatred for Gamora stemmed from and it was enchanting to watch over the sisters attempt to move past their competition . They were so close , until Gamora was killed by Thanos ’s bridge player .

Worst - Iron Man And Ultron

Poor Tony . All he ever wanted was to economise the world and to forbid his Friend from dying horrible death at the hired man of Thanos . Unfortunately , in trying to do so , he make Ultron , a genocidal , insane , homicidal computing machine political platform . of course , the rest of the Avengers were n’t on the nose thrilled with this development , none more so than Ultron himself .

Ultron resented Tony for land him into a world so full of suffering . He saw his canonical role was ' to save the world ' and interpret this as wiping out human race so that the world could begin afresh . This rivalry was rather one - sided and to be honest , Ultron ’s motivations were a little puzzling .

Best - Captain America And Iron Man

Every awe-inspiring rivalry lets hearing understand and bear on to both sides of the conflict , to the stage where they ’re unsure of where their allegiances lie . The seeds for the rivalry between Steve and Tony were sewn justly at the minute when they first met , when neither were certain that they could trust the other .

The semen started to blossom duringAge Of Ultronwhen Tony create the titulary character without consult any of the squad . The competition then blew up altogether duringCivil Warthanks to the Sokovia Accords . This split up the Avengers totally , resulting in them losing stunningly to Thanos inInfinity War .

Worst - Justin Hammer And Tony Stark

This was another fairly one - sided rivalry involving Stark but to be fair , Hammer was , and always will be , utterly pathetic . When Tony outed himself to the world as the superhero Iron Man , it was inevitable that the government would want to obtain his plus and that other inventors would go wild trying to best Tony ’s suits of armor .

Hammer was one of those such inventors but regrettably for everyone involved , he really was n’t very in effect at , well , anything really . He became reasonably of a jest throughoutIron Man 2 , even get to fall back to asking Whiplash for assistance , and we all know how successful that finical enterprise was …

Best - Thor And Loki

We say that theMCUknew how to do sibling rivalries and none are good than the rivalry between Thor and Loki . Admittedly , it ’s thanks in part to Tom Hiddleston ’s magic portrayal of Loki as he ’s the ultimate villain everyone loves to detest . However , credit must be given to Chris Hemsworth and the chemistry he shares with his conscientious objector - lead .

Their kinship has been implausibly antipathetical at time but we always got a impression that Loki was never completely irredeemable . We were constantly rootle for Thor to finally get through to his loggerheaded blood brother and then , when he finally did , Loki got stamp out by Thanos whilst seek to prevent him from acquiring an Infinity Stone .

Worst - Black Widow And Hawkeye

see that these two characters are suppose to be the good of friend , they for sure do spend a sight of their meter face off against one another . InAvengers Assemble , audience did n’t get to see much of their firm friendly relationship . Instead , thanks to Loki ’s judgement ascendency , Hawkeye spent the majority of the film as a subaltern opposer .

Natasha make do to subdue him but they started fighting all over again inCivil War , thanks to the rift between Tony and Steve . Thankfully this combat was more blithe than others . Their final battle came inEndgame , where they fought to preserve the other ’s life . It was n’t much of a rivalry but they still fought more than most and no one really knew why they were fighting .
