This will be written as someone who has watched most marvel movies several times and a overt respect for continuity and cause and effect as well as a theme of revenge and life expanding upon Civil Wars themes

Opening shows the Watcher talking about timelines and such, bringing up the value of one person compared to the infinite cosmos. Raising the question of if a single life matters in a reality so big.

Then to Civil war. The un bombing scene plays out the same but when T'challa is cradling his father we pan out to Natasha dead on the other side of the room. This is possible as she herself admits her surviving was only a matter of luck.

 This makes caps job a lot harder as Hawkeye joins the Iron man team, convinced that Bucky killed his best friend (similar to T’challa and in line with his character as he is shown in endgame). Insert a scene of them both discussing their grief reinforcing to T’challa that revenge is justified. Hawkeye being on team Ironman makes Wanda indecisive, unable to be fully swayed as Clint isn’t there to convince her. She stays out of the fight. 

Final team matchup in the airport is 

Cap, Falcon, Bucky, Antman vs Ironman, Black Panther, Hawkeye, War Machine.

 Vision stays home with Wanda, not wanting any more blood and Ironman doesn’t contact Spider-Man, viewing this situation as more dangerous than in the main timeline as an Avenger has already died. 

The fight ends with only Bucky escaping. Without Widow holding T’challa back Cap has to do it. 

Cut to the raft, it plays out like normal, Sam tells Tony where to go after Zemo reveals to the world he bombed the UN. 

T’challa and Clint follow him together, united in a common purpose of getting revenge. The end fight has Tony killing Bucky as he is no match without cap. At the same time Hawkeye and Black panther confront Zemo, they argue about if they should kill them and Hawkeye does. 

Now to infinity war

Without Wanda being on the run, Vision and her stay at avengers HQ when the children of Thanos attacks. It’s a close fight but the addition of War Machine makes them win the fight not after vision sustains heavy injuries. Without cap to talk him out of it and the location of Wakanda Vision gets Wanda to destroy the stone, killing him.

On titan thing go a lot worse. Without Spider-Man every guardian dies in the meteor shower, leaving Thanos to kill Tony. Strange doesn’t give the stone as he sees in the timelines that they’ve already won and Thanos kills them. The story ends with cap in jail, Tony, the guardians, Zemo, and Vision dead, cap and his team still in prison and Hawkeye in Ronan mode.

Closing narration from the Watcher talking about how one life could change the outcome of the entire universe 



Writing exercise showing the wasted potential of What If. What if Black Widow died in the UN bombing
