History Fanfic / IfICouldStartAgain

** Peter makes a brief cameo as a child during the ending events of ''Iron Man 2'' alongside his aunt May and uncle Ben. He later appears with Ben and May at [[spoiler:Tony's press conference to introduce the Asgardians to Earth, Ben striking up a conversation with Steve when Steve sits beside them]].
** Captain Marvel makes a brief appearance in chapter 23 when The Warriors Three try to find Thor and Loki, only to find her.

** Even during his bloodthirsty warlord days, Odin was reportedly so against Thanos' ideas for culling the universal population that he kicked him out of Asgard as soon as he discovered his true intentions and waged war with him.

* GroundhogDayLoop: According to the Ancient One, [[spoiler:Thor is in one - his accidental usage of the Time Stone will send him back every time he fails to complete his mission, and potentially even send him back even if he does everything right and eventually dies of old age. This is a problem, because doing so will put a great deal of additional strain on the Time Stone of the present day, potentially destroying it if he loops too many times. Fortunately, the Ancient One is able to break the spell so that he will just have this one do-over]].

* MistakenForMisogynist: Steve Rogers feels that this applies to him when he realizes that he assumed Jemma Simmons was the nurse rather than the doctor, but Doctor Simmons assures him that she appreciates that he's from a time where a female doctor would be less common.

* ThatCameOutWrong: Fandral's initial refusal to share why he committed treason nearly gets him killed until he explains that he feels his reasons for doing so are irrelevant compared to the fact he did.

* DidntSeeThatComing: Brunnhilde aka Valkyrie was caught off guard by Odin's ignoring the fact she is technically a deserter and oath breaker and him admitting sending the Valkyries to fight Hela was grave tactile error on his part. She didn't know what to say when he explained he didn't join the Valkyries in fighting Hela because Hela's supporters had killed Baldur and were going to make a move against Odin and Loki.

** An example that's PlayedForLaughs is any mention of Loki being Sleipnir's 'mother'. When Loki tries to clear up any misunderstandings about how some Asgardian myths are based on drunken tales and flights of fancy, he specifically mentioned that particular tale first, with him even threatening his brother with a dagger. Tony Stark also brings it up while speaking about how proud he must've been, causing Loki to give him a ''very'' unamused look.

* SmugSnake: Ebony Maw is one by virtue of being a rampant case of UnderestimatingBadassery despite being an incredibly powerful [[MindOverMatter Telekenetic]] and one of [[BigBad Thanos']] EliteFour. Maybe becuase he's one of the most feared beings in the series, he tends to drastically overestimate himself against those who he tries to menace, utterly unaware that the reason said beings he tries to menace do not fear him is simply because they are ''that'' much more powerful than him. Notably he falls into [[DirtyCoward shamelessly groveling for his life]] when he realizes that his attack on The Grandmaster does [[NoSell absolutely nothing]] and and The Grandmaster seems more peeved at the his ruined clothes than being impaled half a dozen times.

* TheGlomp: A RunningGag of Thor’s is that he has a tendency to hug anyone that he’s friends with a little too tightly, which is fine if it wasn’t for his Asgardian physiology making them (the people from Earth, specifically) feel like they’re being squeezed like a python.

Unlike the ending of ''Film/AvengersInfinityWar'', where Stormbreaker lands at the center of Thanos' chest, it instead lands two inches to the left and renders the Titan's left arm useless. Now unable to use the Infinity Gauntlet, Thor finishes him off, but VengeanceFeelsEmpty. Without thinking, he takes the Time Stone from the Gauntlet, and his mind is sent back in time to [[Film/{{Thor}} before his coronation]], with everyone still alive. Now he has his chance to set everything right, and ensure that everyone he cares for survives what is to come.

** Peter makes a brief cameo as a child during the ending events of ''Iron Man 2'' alongside his aunt May and uncle Ben.

** When [[spoiler:Steve is looking at photographs of Camp Leigh with Coulson, he's quick to stop the addition of the bunker containing Zola's computer-brain]].

* UnderestimatingBadassery: Ebony Maw severely underestimates both Thor and the Grandmaster. The former utterly obliterates Cull Obsidian once he stops playing around and the latter reacts with annoyance when Maw impulsively impales him with several spears. In the Grandmaster's case, it occurs to Ebony Maw that he should have considered that Thanos is willing to do business with the man and give in to his demands than simply conquer Sakaar.

* BeenThereShapedHistory: Loki reveals offhandedly that he used to be one of {{Creator/WilliamShakespeare}}'s original actors.

* RationalFic: For the House of Odin, the family members actually sit down and talk out their issues rather than leave them bottled up to stew and eventually cause problems. There's still plenty of family drama, but it's more of the standard family drama and not the "put the Nine Realms in danger" type of drama.

* InternalReveal: Chapter 28 features [[spoiler:Clint and Natasha]] learning about Thor's time travel, as well as details of the timeline he came from.

* SecretKeeper: Outside of his parents, Loki, Sif and the Warriors Three, Hawkeye and Black Widow are the only non-Asgardians Thor has told about his experiences in an alternate future timeline, and they have agreed to keep that detail from Fury and the other Avengers (the Ancient One also learns the truth through her experience of the Time Stone, and thus reveals it to Brunhilde and Kaecilius).

* TrustPassword: In order to gain Hawkeye and Black Widow's trust after they learn that he's from the future, Thor tells them about when they went to Clint's house during the Ultron incident and about his family when they first met them. Since the only way Thor would know about Clint's family in the first place would be if he had his absolute trust, he accepts Thor's claims.

* AchievementsInIgnorance: Thor's encounter with Peter Parker means that he has met the one Avenger he would definitely ''never'' have met or heard of in the original timeline (someone may have mentioned T'Challa to him during the Battle of Wakanda and he was at least aware of Bucky, Sam and Rhodey even if he didn't directly fight alongside them).

* FirstContact: Tony sets one up in the form of a hearing to introduce Thor, Loki and Brunhilde to the world. [[spoiler:In spite of the Winter Soldier's efforts to muck it up by trying to assassinate Tony, it goes quite well.]]

** Without Thor having even planned on it, his actions also cause [[spoiler:Ava Starr to discover the existence of HYDRA, resulting her rebelling against S.H.I.E.L.D. and kill Alexander Pierce. While the consequences of this are as of now unclear, Ava's actions will undoubtedly make the imminent battle against HYDRA a little bit easier]].

* MentalTimeTravel: Thor himself isn't sent back to the past, but rather his mind after he killed Thanos in ''Infinity War'' is sent back to his pre-coronation body after he picks up the time stone from the gauntlet.

* HoistByHisOwnPetard: [[spoiler:Alexander Pierce sends Ava Starr to spy on the would-be Avengers. She ends up walking in on the team right as they are discussing how to deal with the HYDRA infiltration, not only revealing the organization's existence to her but also confirming the fact that they had never intended to cure her condition. She subsequently kills Pierce in cold blood.]]

* IDidWhatIHadToDo: Essentially Odin's justification for why he basically 'framed' the Jotun for the destruction of the Valkyrior after erasing all record of Hela; since Hela gained power from her followers on Asgard even after being cut off from Asgard itself, the only way to ensure she couldn't gain further power was to erase all knowledge of her, which including creating a scapegoat for the destruction of the Valkyrie.
