History Recap / WhatIfS2E2WhatIfPeterQuillAttackedEarthsMightiestHeroes

* BittersweetEnding: Thankfully one leaning more towards the "sweet" this time around. Though Ego managed to destroy much of the Nine Realms and his planetary core is still a vying threat, the Avengers form several years earlier and manage to stop him from destroying Earth, and Peter is adopted into the Pym-van Dyne family. Not to mention that Bucky has left HYDRA in order to reclaim his past, meaning there is little to no chance of Howard and Maria Stark dying in a few years.

** In the main timeline, Hank Pym, Bill Foster and King T'Chaka were {{Heroes of Another Story}} whose superhero careers were long past them in the present day. Here, not only do we get to see them in action, but they help fight against Ego the Living Planet himself, something their 616 counterparts never did.

* MythologyGag: Thor joining the Avengers in the battle against Ego brings to mind how the two of them are recurring enemies in the comics.

** Peter has far more control of his celestial powers than his 616 self did despite being far younger, likely due to the six months of training he got from Ego. Also unlike his 616 self, Peter retains his celestial powers by absorbing the celestial seedling, noting that it means a piece of Ego will always live inside him.

* AdaptationalEarlyAppearance: In this universe, the Avengers form several decades earlier due to the threat of Ego looming over Earth at this time.

** In the main timeline Peter has never met Hank and Hope on screen (bar the Battle of Earth and a group meeting at Tony's funeral), here they seem set to become his adoptive father and sister.

* AlreadyDoneForYou: Thor explains how Ego causes the Expansion, namely his seeds planted anywhere on planets he intends to absorb. Before anyone at S.H.I.E.L.D. can suggest looking for the one on Earth, he reveals he already found it, and that's why he was late showing up to the fight with Peter.

* ChekhovsGun: The celestial seedling Thor that picked up in Missouri when first arriving on. Earth, it not only warns the Avengers when Ego is sending his avatar to Earth but it also gives Peter the power to destroy his father’s avatar after he absorbs the seedling.

* EnemyMine: Peter is a big enough threat that the Soviets (or more likely the Soviet representatives of HYDRA) sends the Winter Soldier (a.k.a Bucky Barnes) to aid S.H.I.E.L.D against him.

* HeelRealization: When Hope calls out the Avengers how they are treating Peter, even though he just a kid and just wants to go home. She agrees to tell her father where he only if he agrees to help, pointing to Hank it’s what Janet would have wanted. Hearing that Hank realizes his daughter is right.

* AdaptationRelationshipOverhaul: In the regular timeline, Hope and Hank's relationship deteriorated after the loss of Janet van Dyne, especially since Hank shipped her off to boarding school because he couldn't deal with his grief. Here, the two seem to have a much healthier father-and-daughter dynamic, with Hank wholly trusting and loving Hope even without Janet keeping them together.

* AdaptationalRelationshipOverhaul: In the main timeline Peter has never met Hank and Hope on screen (bar the Battle of Earth and a group meeting at Tony's funeral), here they seem set to become his adoptive father and sister.

* AdaptationRelationshipOverhaul: On 616, Hope and Hank's relationship deteriorated after the loss of Janet van Dyne, especially since Hank shipped her off to boarding school because he couldn't deal with his grief. Here, the two seem to have a much healthier father-and-daughter dynamic, with Hank wholly trusting and loving Hope even without Janet keeping them together.

** In 616, Hank Pym, Bill Foster and King T'Chaka were {{Heroes of Another Story}} whose superhero careers were long past them in the present day. Here, not only do we get to see them in action, but they help fight against Ego the Living Planet himself, something their 616 counterparts never did.

* AdaptationalDiversity: Compared to the 616 Avengers, the team in this universe is far more diverse with characters of different ethnicities and nationalities... and even species.
* AdaptationalEarlyAppearance: In this universe, the Avengers form several decades earlier than they do on the 616 due to the threat of Ego looming over Earth at this time.

** Peter is imprisoned in the same type of cell that would be [[Film/TheAvengers2012 intended]] for the [[Characters/MCUBruceBanner Hulk]] in the 616.

%%** Once again, someone compares Thor to The Dude from ''Film/TheBigLebowski''.

* FiveManBand: The 80's Avengers have this dynamic in spades; Hank Pym/Ant-Man, owing to his intelligence, training and years of experience as a superhero and S.H.I.E.L.D. agent [[TheLeader giving him the abilities to command the team]]. [[TheLancer King T'Chaka]] as the team's second foremost member, throwing himself into the danger at the first sign. [[TheBigGuy Bill Foster]], who has cracked the Pym Particles' ability to grow and become able to grow giant, providing the team muscle. [[TheSmartGuy Wendy Lawson/Marvell]], who despite having superhuman abilities as a Kree, sticks to acting as team support and providing the team with vital info on Ego. [[TokenEvilTeammate The Winter Soldier]], sent by his Soviet handlers to handle the threat with his unique abilities as an assassin and the first one to suggest simply murdering Peter as the solution. [[SixthRanger And Thor]], who comes to save the team at New York after Peter proves too much for them to handle. Hank also pulls double duty as TheHeart by being the first one to realize that Peter is just a grieving kid being manipulated and getting him to confront his father and prevent him from annihilating humanity.

* MythologyGag: Thor joining the Avengers in the battle against Ego brings to mind how the two of them were recurring enemies of each other in the comics.

* PopCulturalOsmosisFailure: When Thor first arrived, Peter mistakes him for a member from Music/VanHalen, not being from Earth Thor doesn’t know who Van Halen is.

** Amusingly, this trope actually applies to Ego himself. Though Peter manages to destroy his human form, Thor points out that his planet form is still out there and poses a threat to the universe, unlike what happened to his 616 self in ''Film/GuardiansOfTheGalaxyVol2''. Although the end of the episode makes it clear the team intend to avert his survival at their earliest convenience.
** Since she's heading off-world with plenty of back up instead of staying put, Mar-vel has a much better chance of averting her canon death.

* CommonalityConnection: Hope and Peter bond over losing their moms recently in their lives, and Hank brings up his own problems with moving on from Janet when trying to break through to Peter

* DoppelgangerAttack: Ego unleashes a massive army of himself (formed from the earth) in the FinalBattle against the Avengers.

* BittersweetEnding: Thankfully one leaning more towards the "sweet" this time around. Though Ego managed to destroy much of the Nine Realms and his planetary core is still a vying threat, the Avengers form several years earlier and manage to stop him from destroying Earth, and Peter is adopted into the Pym-van Dyne family. Not to mention that Bucky has left HYDRA in order to reclaim his past.

'''Peter:''' Actually, old man, my mom says [[SayMyName I'm a Star-Lord]]!

** Hope bonding with Peter, along with convincing the other Avengers to help him, is what causes Peter to turn against Ego.
** Howard Stark convincing Bucky to stand down allows him to brake free of Hydra's control, thus saving him and his wife from being killed three years later.

** Since she's heading off-world with plenty of back up instead of staying put Mar-vel has a much better chance of averting her canon death.
** With Bucky free and the infiltration at a much earlier stage the episode leaves open at least the possibility that the Hydra infestation in SHIELD might be discovered and dealt with before the organisation has to be destroyed this time.

* AdaptationalRelationshipoverhaul: In the main timeline Peter has never met Hank and Hope on screen (bar the battle of Earth and a group meeting at Tony's funeral), here they seem set to become his adopted Father and Sister.

** Due to Bucky freeing himself from HYDRA's control a few years early, Howard Stark is no longer in any danger of being killed at his hands in 1991.
** Amusingly, this trope actually applies to Ego himself. Though Peter manages to destroy his human form, Thor points out that his planet form is still out there and poses a threat to the universe, unlike what happened to his 616 self in ''Film/GuardiansOfTheGalaxyVol2''.

* AdaptationRelationshipOverhaul: On the Sacred Timeline, Hope and Hank's relationship deteriorated after the loss of Janet van Dyne, especially since Hank shipped her off to boarding school because he couldn't deal with his grief. Here, the two seem to have a much healthier father-and-daughter dynamic, with Hank wholly trusting and loving Hope even without Janet keeping them together.

** In the Sacred Timeline, Hank Pym, Bill Foster and King T'Chaka were {{Heroes of Another Story}} whose superhero careers were long past them in the present day. Here, not only do we get to see them in action, but they help fight against Ego the Living Planet himself, something their Sacred counterparts never did.
** Peter has far more control of his celestial powers than his Sacred Timeline self did despite being far younger, likely due to the six months of training he got from Ego. Also unlike his Sacred Timeline self, Peter retains his celestial powers by absorbing the celestial seedling, noting that it means a piece of Ego will always live inside him.

** Peter is imprisoned in the same type of cell that would be [[Film/TheAvengers2012 intended]] for the [[Characters/MCUBruceBanner Hulk]] in the Sacred Timeline.

* TheCameo: The credits show that the voice speaking to the Winter Soldier as he's preparing to shoot Quill is none other than Vasily Karpov, the HYDRA soldier that Helmut Zemo drowns in the Sacred Timeline.

** Amusingly, this trope actually applies to Ego himself. Though Peter manages to destroy his human form, Thor points out that his planet form is still out there and poses a threat to the universe, unlike what happened to his Sacred Timeline self in ''Film/GuardiansOfTheGalaxyVol2''.

* SuddenlySpeaking: The Winter Soldier starts speaking once the Avengers begin talking about what they need to do with Peter after he escapes, saying they to kill him.

** At Coney Island, Peter acquires a stuffed raccoon toy from an abandoned stall.

** While Peter is on Coney Island, despite destroying the stall where got a a stuffed raccoon, he is mostly enjoying himself and having fun. He only starts creating more destruction after the Avengers start attacking him. This is a sign he really means no harm and it’s Ego who controlling him.

* GooGooGodlike: Peter has the powers of a celestial god, but he only uses them to have a fun at a carnival. It's [[OmnicidalManiac his father who uses them to destroy worlds]].

** Ego still reveals to Peter that he killed his mother in this universe, which leads to Peter fully turning on him.

* TheReveal: King Azzuri, who's the father of T'Chaka and N'Jobu and the grandfather of T'Challa, Shuri, and N'Jadaka, was revealed to be the one who donated the vibranium to Howard Stark that would later be used to make Captain America's shield because Azzuri allied Wakanda to the United States during UsefulNotes/WorldWarII.
* SeriesContinuityError: It's heavily implied in ''[[Film/TheAvengers2012 The Avengers]]'' that the cage used to hold Peter was built to contain the Hulk. But MCU Bruce Banner would only be a child in 1988.

* WiseBeyondThierYears: Hope is the one that first realizes Peter really wants to go home and doesn’t mean harm, which why she sets him free. Then she tells the Avengers how they show be doing the right, such as helping Peter, and realizing Ego is the real threat.

* YouCanTalk: Bucky's teammates reaction when he advocates for [[MurderIsTheBestSolution killing Peter]].
