“In which Tony Stark built his friends (but his family was assigned by Nick Fury)” by scifigrl47
Colloquially known as “The Toasterverse”, the epic masterpiece in a scifigrl47 series was released before The Avengers. Much of the series takes place in Tony Stark’s POV Human Catastrophe, who tries to get used to people who actually care about him mixed with confusing feelings towards Steve Rogers. The series is hilarious and heartwarming with major “Avengers as a found family” vibes.
The couples in the series are Steve Rogers / Tony Stark, Clint Barton / Phil Coulson, Thor / Jane Foster with many other couples. It also folds into both the MCU and other Marvel properties such as the X Men, Andrew Garfield Spider Man movies, and more. It’s a very rich world and a big disappointment that the series hasn’t been updated since 2015. But what there is is amazing and you have to check it out.
Culture and other balls of string by LithiumDoll
Following the events of 2012 Avengers movie, Tony “kidnaps” Bruce to go on a road trip before having to deliver to a special lab to work. During the trip, Nick Fury sends the other members of The Avengers to pick up the heroes of old, except they are also taken on the ride. It’s really nice to see them all come together and at five chapters with 17,000 words, that packs a lot into the story.
Seriously, though, it’s a relatively underrated fic. It’s great if you are looking for a nice post-The Avengers fic.
“Magazineverse” by Copperbadge
Copperbadge is a prolific author of fanfic through several fandoms. Seriously, their work is one of the best. If we have to pick one Avengers fanfiction by Copperbadge, so we’re going with the Magazineverse. Written as an outside perspective, one writer follows the Avengers for a few days so that people, in general, can get to know the mysterious superheroes.
Carried out like a magazine article, the first two fics of the series are excellent, taking place after Avengers and post Winter Soldier respectively. The revelation of who the author is at the end of the first fic is too big not to spoil here. Basically, this is a great series featuring great character dynamics while keeping the tone with a magazine article.
let’s keep our eyes on the cracks by napricot
Remember how people really wanted Thanos to be defeated by Scott Lang who rolls his butt up and then stretches out, causing him to explode? Yes. It was a theory. This fanfic imagines him with the consequences in the most hilarious possible way. It is so glorious. If you don’t like how Avengers: Endgame finished things off and then go the most hilarious way possible.
Seriously, we almost died laughing several times during the fic. “Don’t say buttsplosion”, indeed.
‘Wear your heart on your skin’ by theredbook
This AU series follows piercist Bucky returning home for a service after a head injury and working in tattoo artist Steve Rogers’ shop. The other Avengers also appear with various friends and relationships that develop over time. The first fic in the series ends at around 40 chapters of excellent slow burn and explores much of the relationship between the group.
Unfortunately, the second fic stopped updating in 2018, but the 18 chapters there are pretty awesome. Seriously, the first fic is absolutely fascinating to read.
