What are some interesting plot ideas in 'avengers of hydra fanfiction'?

Well, a possible plot could be that the Hydra experiment was actually a cover - up for a much larger and more sinister plan. The Avengers discover that the experiment was just the tip of the iceberg and they have to race against time to stop Hydra from unleashing something far worse. It could also be interesting if the experiment somehow gives an ordinary person the ability to see into the future, and that person becomes a key figure in the battle between the Avengers and Hydra.

One idea could be a character with the Hydra Bloodline having the ability to split into multiple versions of themselves during battles, like the Hydra in mythology. Each split could have a different combat skill, making it a very unique fighting style.

One idea could be a crossover where Hydra discovers the wizarding world in the Harry Potter universe and tries to use magic for their evil purposes. The Avengers somehow get wind of this and team up with Harry Potter and his friends to stop Hydra. Maybe they have to battle magical creatures that Hydra has corrupted with dark magic.

One plot idea could be that Captain Hydra, in a universe where he exists, tries to recruit Tony for his evil plans by appealing to Tony's scientific curiosity with some dark technology. Another could be a scenario where Tony, initially unaware of Captain Hydra's true nature, teams up with him for a project but slowly discovers the truth and has to fight against him. Or perhaps a story where they are both caught in an alternate dimension and must work together, reluctantly in Tony's case, to find a way back home while Captain Hydra keeps trying to undermine Tony's good intentions.

A possible plot for a 'Hydra Kidnaps Darcy' fanfiction could involve Darcy's sassy attitude getting on the nerves of her Hydra captors. This could lead to some humorous exchanges while still maintaining the tension of the situation. Meanwhile, the Avengers are frantically searching for her. Captain America might use his leadership skills to coordinate the search efforts. Back with Darcy, she could try to form an alliance with other captives in the Hydra base. Together, they could come up with a plan to revolt against their captors and escape before the Avengers arrive.

A really cool plot idea could be that the Avengers are watching Endgame in a sort of 'alternate reality cinema' where the events in the movie start to bleed into their real world. So they have to stop the movie from fully playing out to prevent chaos in their own universe. This would involve a lot of action and strategic thinking as they try to stop things like Thanos from emerging from the screen while also trying to understand the significance of what they're seeing in the movie.

One idea could be that the summoner has to learn how to control the hydra's multiple heads which all have different personalities. For example, one head could be aggressive and always want to attack, while another is more cautious.

One idea could be that the mutants and the Avengers have to team up against a common enemy that is immune to their individual powers. So they must learn to combine their abilities in new ways. For example, Wolverine's healing factor could be used to keep an injured Avenger alive during a long battle while Iron Man figures out a way to defeat the enemy.

One idea could be that Harry Potter is magically transported to the Avengers' universe. He could use his magic to help the Avengers in battles, like creating protective shields with spells. Another idea is that the Avengers are somehow sent to Hogwarts, and they have to learn about magic while also dealing with threats in the wizarding world. For example, Iron Man might try to figure out how to integrate his technology with magic.

One idea could be exploring the family dynamics when the Avengers have to take care of a young superhero in training. It would be fun to see how they each contribute to the kid's growth, like Tony Stark teaching about technology and Captain America instilling values.
