One idea could be exploring what if a minor character from the movie got the Infinity Stones instead. For example, a random Asgardian warrior. They might use the power in a completely different way, perhaps trying to restore Asgard rather than the more universal aims Thanos had.
A fanfiction could focus on a young, unknown character who discovers a rare and powerful disk. This character then teams up with the Marvel heroes to learn how to use it properly and to help in their battles. For example, they might have to face off against an old enemy who has returned stronger than ever.
One idea could be a new character joining the Avengers. For example, a young mutant with the power to control time. This character could accidentally disrupt the timeline while trying to prove themselves to the team, leading to all sorts of chaos and adventures as the Avengers try to fix it.
A great Disk Wars Avengers fanfiction idea might involve a young, new character who discovers a special disk that has the power to summon the Avengers. But this disk also attracts the attention of evil forces. So, the young character has to learn how to work with the Avengers and protect the disk from falling into the wrong hands. The story could explore themes of friendship, courage, and growing up while also incorporating the unique elements of Disk Wars.
Howard the Duck. It would be really unexpected. He could bring some comical relief but also have some hidden knowledge about the disks that could be crucial. For instance, he might know of a weakness in a powerful enemy's disk - based powers.
One idea could be that the Avengers discover a new form of happiness that is not based on victory but on self - discovery. They each go on a journey to find what truly makes them happy outside of their superhero personas.
One idea could be to cross the Avengers with the characters from Harry Potter. Imagine Iron Man trying to figure out how to use a magic wand, or Thor comparing his hammer to a magic broomstick. Another idea is to crossover with the Star Wars universe. Captain America leading the Rebel Alliance against the Empire would be really cool.
One idea could be a crossover where Naruto gains Saiyan powers and teams up with the Avengers. He could use his newfound Saiyan strength and speed, combined with his ninja skills, to take on powerful villains. For example, against Thanos, Naruto could use his Rasengan enhanced with Saiyan ki energy.
One idea could be a crossover where the Avengers end up in the wizarding world of Harry Potter. They might be confused by the magic at first but then start to learn and adapt. For example, Iron Man could try to figure out how to incorporate magic into his tech. Another idea is that Harry Potter and his friends are brought to the Avengers' universe and they help the Avengers fight a new kind of threat that has both magical and non - magical aspects. Maybe Voldemort somehow teams up with a supervillain from the Avengers world.
A great plot for Star Wars The Clone Wars fanfiction could be centered around a new, unknown planet that gets caught in the middle of the war. The planet has its own unique species and culture. The story could follow how the clone troopers and the Jedi interact with this new civilization, whether they try to protect it or use it for their own strategic advantages. Or perhaps a story where a group of clone troopers start to develop their own individual personalities and question their loyalty to the Republic due to some unethical orders they receive. This could lead to a conflict within the clone ranks and force the Jedi to take sides.
