A less obvious but still common theme is the idea of sacrifice. In some fanfictions, either Steve or Tony is put in a situation where they have to sacrifice something for the other or for the greater good of the Avengers. This shows the depth of their bond and how far they are willing to go for each other.
One common theme is the exploration of their complex relationship. Since Steve and Tony have different personalities and ideologies, fanfictions often focus on how they navigate their differences and find a connection. Another theme is friendship and loyalty within the Avengers. Their relationship is often set against the backdrop of the team's dynamics.
There are also a lot of 'fix - it' fics. These are stories where the writer tries to 'fix' the events in the movies that they didn't like, especially those that caused conflict between Steve and Tony. For example, after Civil War, many fics try to bring them back together in a more harmonious way.
One great 'Avengers Assemble Stony fanfiction' is 'A Different Perspective'. It delves deep into the relationship between Steve and Tony, showing their growth and how they come to understand each other on a whole new level. The characterizations are really well - done, staying true to their personalities from the movies.
Another theme is power and responsibility. Since the Avengers are powerful heroes, fanfics often explore how they handle their powers. Some stories might show a character struggling with the consequences of using their powers too recklessly.
One common theme is loyalty. Fans often explore which side characters will choose during the feud and how far they will go to stay loyal to their beliefs or friends. For example, will Hawkeye stay true to his long - time Avengers comrades or be swayed by new alliances?
The theme of friendship - turned - more - than - friendship is also quite prevalent. They start as comrades in the Avengers, but in many stony fanfictions, their bond deepens into a romantic or at least a very deep emotional connection. It's about how that transformation happens and what it means for both of them and the rest of the team.
Isolation is also a theme. Often, the character who is 'hurt' will isolate themselves from the other. Tony might lock himself away in his lab, thinking he doesn't deserve Steve's love or friendship after something has happened. This adds to the overall atmosphere of pain and the need for reconciliation in the fanfiction.
One common theme is the conflict of ideologies. Steve's more traditional view of freedom and Tony's more utilitarian approach often clash. Another theme is friendship and betrayal, as they were once allies and now are on opposite sides.
I really like the fanfiction titled 'Loki's Role in Avengers Assemble'. In this story, Loki is forced to work with the Avengers against a greater threat. It's full of action and interesting character dynamics. There's also 'Loki's Secret Mission with the Avengers' where Loki has a secret mission that only he can do, but he has to cooperate with the Avengers. And 'The Avenger - Loki' which gives Loki a more heroic role within the Avengers Assemble universe.
One great 'Marvel Avengers Assemble' fanfiction is 'The New Recruit'. It focuses on a new character joining the Avengers and how they adapt to the team's dynamics. It has really interesting character interactions and some cool action scenes.
One idea could be that Naruto is somehow transported to the Marvel universe where the Avengers are. He could use his ninja skills, like his shadow clone jutsu, to confuse the villains that the Avengers are facing. Maybe he teams up with Iron Man and they combine their tech and ninjutsu to create some really cool weapons or defenses.
