If you think the Marvel Cinema Chronology is something of a marvel (see what I did there) you are absolutely right! Here at Nerdy, we have taken on our super powered (I wish) shoulders to crack that puzzle wrapped in enigma for you! You are welcome!
So, sit back, buckle your seat belts, put on your helmets and prepare to be whooooshed through The Marvel Universe and Time!
Before universe began:
The Cosmic Entities Death, Entropy, Infinity, Eternity, part of the Celestial race, used 6 singularities to create the 6 infinity stones-Space, Mind, Reality, Power, Soul, and Time. They have power over creation and influence events throughout history
The Dark Elves of Svartalfheim were an advanced race older than the Asgard. They can’t adapt to the growth of life and civilization around them and want to reverse the universe back to what they know. The method of choice is genocide. They plan to use the Aether from the stones, during a celestial event called The Convergence, to destroy the 9 realms. The 9 realms ( Asgard, Vanaheim, Alfheim, Midgard, Jotunheim, Svartalfeihm, Nidavellir, Niflheim,Muspelheim) are planets linked by the cosmic tree Yggdrasil with Asgard ruling. With a great loss to both armies Odin’s father Borr wins the war and seizes the Aether. The Dark Elves’ leader Malekith escapes and puts his remaining forces into a sleep, which lasts millennia. Borr hides the Aether.
The Frost Giants of Jotunheim attempt to conquer Midgard/Earth. They start the invasion in Tonsberg, Norway. Odin, leading the Asgard army, in an epic battle forces the Frost Giants back to Jotunheim, saves Earth and seizes the source of their power, the Casket of Ancient Winters. He finds an abandoned Frost Giant infant, who he adopts, names Loki and raises with his own son Thor. Also the Tesseract, one of the infinity stones is hidden on Earth during the battle.
As we are only following the Marvel Cinematic Universe I am leaving out the creation of Inhumans by a rogue Kree fraction, genetically altered sentient species, which get superpowers when exposed to the Terrigen Mist; the creation of It, Death, Hell-Beast (pick a name, it’s all the same badass), a couple of long wars out there, the Berserker Staff etc. You can catch up on those in Agents of S.H.I.E.L.D.
Abraham Erskine works on serum that gives the subject superhuman strength and abilities. He refuses to cooperate with the Nazis, but gets captured by Johann Schmidt, the head of SS research division H.Y.D.R.A. and made continue working on the formula. Erskine is forced to use the Super Soldier serum on Schmidt, which turns him into Red Skull. Erskine later escapes with the help of Agent Peggy Carter and returns to United States of America. Schmidt begins to despise Hitler and seeks a weapon to overthrow him. During his research in ancient history he learns about the Tesseract, which was lost from Odin’s vault. He finds it and begins tests to harness its power.
In New York numerous attempts of Steve Rogers to enlist in the army were turned down, because of his many health issues until a conversation between him and his best friend Bucky Barnes is overheard by Professor Erskine. Erskine decides to enlist Rogers as a candidate for the Project Rebirth, a super-soldier experiment. In the end Rogers is picked and becomes Captain America. He is the first and only successful recipient of the serum.
Shortly after Erskine is killed by a spy working for Schmidt. The last vial of the serum is stolen, and later destroyed during a fight.
Some time later Rogers learns his friend Barnes’ team is MIA and goes on an unauthorised mission to H.Y.D.R.A. fortress to find him, aided by Agent Carter and Howard Stark (Tony Stark’s father). Once there he steals a piece of Tesseract technology and finds Bucky strapped to a table. They escape and form the Howling Commandos and continue to destroy most major H.Y.D.R.A. operations, which slows H.Y.D.R.A.s efforts in building an army. During one operation Barnes falls to, what everyone believes is his death. After one last epic battle and the death of Red Skull, Rogers crashes an aircraft in the ocean trying to destroy the Tesseract. Time passes and the world forgets for 66 years.
Howard Stark, Chester Phillips and Peggy Carter create the Strategic Homeland Intervention Enforcement and Logistics Division or S.H.I.E.L.D. However the remnants left behind of Red Skull quietly infiltrate S.H.I.E.L.D.
Agent Carter TV series 1st and 2nd season and Marvel One-Shot Agent Carter fit here.
Hank Pym goes before Howard Stark, Peggy Carter and Mitchell Carsdon and hangs his resignation to S.H.I.E.L.D. after discovering their attempt to duplicate his shrinking technology. He believes it’s dangerous and will take the secret to his grave.
Bucky is found and brainwashed by S.H.I.E.L.D.
He is turned into The Winter Soldier and assassinates global leaders over the course of decades.
Howard Stark and Anton Vanko begin work on Arc Reactor technology, which will eventually power the Iron Man suits. Stark steals credit from Vanko and Vanko is deported back to Russia.
Soviets begin work on their super soldiers-Red Room and Black Widow program.
Peter Quill aka Star-Lord is kidnapped from Earth.
Tony Stark meets Maya Hansen, who is working on the Extremist project, and Aldrich Killian.
America is still working on super-soldiers.
Robert Bruce Banner and his girlfriend Betty Ross are recruited by the Armed Forces to work on a top secret project, which is trying to replicate the results of Project Rebirth. They decide to use Gamma radiation instead of Vita radiation used by Professor Erskine. After months of research Banner decides to test the serum on himself. He undergoes a violent transformation and his alter ego Hulk is created. When he becomes angry or excited and adrenaline is released in his system, Banner transforms into a very angry huge, green-skinned, muscle giant with incredible strength and attitude problems. After finding out they want to use him as a weapon he escapes.
Tony Stark becomes an arms dealer and gets kidnapped by the Ten Rings. Another captive, Yinsen, fits a roughly made electromagnet into his chest to keep away shrapnel shards from reaching his heart. The two begin to work in secret to create a suit of armour, powered by a mini arc reactor, to help them escape. When Stark escapes, he uncovers the corruption in Stark Industries, which lead to his capture. Stark creates the first Iron Man suit and wins his first battle. He comes out to the press as being Iron Man. Nick Fury approaches him with the Avengers Initiative.
Things speed up quite a bit from here and everything happens at once, so be warned!
Time passes and Stark upgrades his suit and is at the top of his game, but his chest is killing him. He gets attacked by Anton Vanko’s son Ivan who is looking for revenge for the treatment of his father by Howard Stark and wants to prove to the world that Iron Man is not invicible. He uses an exoskeleton he designed himself and called Whiplash.
James Rhodes becomes War Machine (and isn’t he loving it!)
Nick Fury reveals to Tony that Natasha Romanoff, who is currently working for Stark, is a S.H.I.E.L.D. agent and gives him his father’s arc reactor notes.
Thor’s coronation on Asgard comes to an abrupt end when the Frost Giants attack, attempting to retrieve the casket. (This always reminded me of Leonardo DiCaprio and his, until recently, lack of Oscar for some reason. Gold and shiny, so close and yet so far)
After some soul searching and his father’s notes Tony Stark creates a new element, which ends up powering his arc reactor and saving his life.
Thor, his adoptive brother Loki and his friends Volstagg, Fandral, Hogun, and Sif invade Jotunheim to take down the Frost Giants without telling dad.
They fail, but Odin saves them. Thor and his hammer Mjolnie are sent to Midgar/Earth for punishment and he is stripped of his powers. (Still hot though!)
Banner returns home to reunite with Betty.
Upgraded War Machine and Iron Man defeat Ivan Vanko.
Furry hires Stark as S.H.I.E.L.D. consultant.
Thor lands in New Mexico and meets Dr. Jane Foster(insert sparks here). Phil Coulson gets a hold of Mjolnir, well kind of, because they can’t move it. Thor finds it, but can’t lift it either, because he is not worthy.
Meanwhile in Asgard…
