However , the franchise had many opportunity during the Infinity Saga to close its doors if it want a clean plot line from commencement to destination . These scope from the Avengers ’ victory to leading characters like Tony Stark achieving the peace they wanted . In retrospect , it ’s interesting to debate how the overarching fib could have concluded , so it ’s deserving taking a cryptic honkytonk into all the scenarios .

When Tony And Rhodey Overcame Whiplash’s Threat

Although the MCU was only three movies in by the timeIron Man 2was unloose , it was a time when many did n’t even recognize this was a cinematic universe .

This was a victorious goal for the couplet and fan could have been left with the idea that Tony and Rhodey would not be protectors of the earthly concern as the squad of Iron Man and War Machine . Since Tony had also take off a kinship with Pepper and reconciled with the memory of his father , his personal electric discharge was also sodding .

When The Avengers Foiled Loki’s Invasion

The movie was the culmination of Phase One of the MCU where the individual pic of Thor , Iron Man , Captain America , and The Hulk work up up to . At the end of it , everyone had reach personal satisfaction and were seen felicitous with what they ’d accomplish . There would n’t have been idle end had the MCU reason decent there .

After Tony Stark Gave Up Being Iron Man

Among the things about theIron Manmovies that have aged poorlyis how the nominal hero went back to wear the suit byAvengers : years of Ultronwhen he promised he was done inIron world 3 . It looked like the finale for his time in the MCU , as Tony destroy all his suit and removed the arc reactor from his chest .

Most fans saw Tony as the representation of the MCU overall at the sentence , which would have made this the last electric discharge for the serial publication as a whole . Since the other poor boy ’ later story had n’t been established by then , Tony ’s retirement would have   seen the MCU bow out as well .

Thor fought a multi - planet engagement against Malekith that ended with him defeating the Dark Elves for good . He rejected Odin ’s offer for him to be crowned as king , as Thor want to retreat to be with Jane . Loki , who was disguise as Odin , acquiesced to this asking and Thor left Asgard .

The Loki plot of ground twist was n’t that grown of a deal since most fans saw him as a breakout character and would n’t have mind him as the young king . Where Thor was concerned , it was made to appear as if his story was done and he could now be happy with the woman he get laid . The ending had keep abreast Tony ’s retirement as Iron Man and would have fit Thor ’s own .

The dispute against HYDRA saw areappearance of Bucky Barnes in the MCU , which ended with S.H.I.E.L.D. amount to an remainder , as Captain America learned it had been infiltrated by the villains . Steve and Sam resolved to search for Bucky after he regained his mind and fled .

This could have played out as an open ending for the MCU , especially since Bucky was subsequently see at a remembrance dedicated to him with the implication that he retrieve who he was . S.H.I.E.L.D. had been project as the glue that had held the dissimilar heroes together at the prison term , and its folding could have served as the MCU ’s termination , too .

When The Avengers Ended Ultron’s Threat

For some fan , Ultron is the effective MCU villainbecause of how nigh he came to causing an extinction - degree consequence . Moreover , the side effect from trade with him lead to a fresh phase for the Avengers , where Thor left for Asgard once more , Hawkeye retired , Hulk decide not to fall back , and Tony go into semi - retreat .

While there were some continuation hook like the tease for the Infinity Stones , things were n’t as concrete either . It would n’t have been that defective of an conclusion if the picture show implied that Captain America and Black Widow would now do their job in looking after the novel Avengers recruits to keep the world safe .

The ending ofCaptain America : Civil Warsaw the Avengers smash apart , with Steve ’s faction plump on the running play after he freed them from the Raft prison . Meanwhile , the remain Avengers stuck to the Sokovia Accords and now worked for the government .

Tom Holland’s Spider-Man upset and determined in No Way Home

It was a bare outlook for certain , but it could still be seen as a definitive determination - just one where thing did n’t work out . Had the MCU settle to close its door there , the story could have been wrapped up with the explanation that the Avengers that were   wanted supervise to acquire institution from T’Challa at Wakanda while Tony Stark ’s group would now do their heroic verse legitimately .

When Doctor Strange Prevented Dormammu From Threatening Earth

It meant the only threat to the MCU at the time was Dormammu , whom Doctor Strange encountered in the Dark Dimension .

The protagonist managed to dicker for the Earth by making Dormammu promise he would n’t endanger the world . Even the post - credits scene of Doctor Strange assisting Thor in finding Odin worked in an open - ended way where spectator could assume they were successful . It was a confirming note of hand that the series had the potential to conclude on .

When Thanos Successfully Completed The Snap

It was the bleakest ending so far in the MCU , but Thanos ’ successful carrying into action of the Snap to dispatch his mission was also a conclusion of sorting . After all , there was no hereafter in sight at the fourth dimension , as Thanos managed to cull one-half of all life in the universe of discourse , leave the heroes overcome .

The overarching plotline of collecting the Infinity Stones had also arrive to an end when Thanos brought them all together to discharge the Infinity Gauntlet . The last barb of Thanos smiling at attain his goal can very well be seen as the closing curtain if fan require to comprehend it that way .

After The End Of The Infinity War

This is where buff might have have an remainder to the MCU if Marvel really need it to happen . The Infinity War was contribute to a finish when Tony Stark obviate Thanos and his forces , with everyone that had perished in the Snap also brought back to lifetime .
