One of my favorite ideas is Iron Man time traveling to key moments in the history of the Marvel Universe. For instance, going back to the time when the Infinity Stones were first scattered across the cosmos. He could try to secure them or at least understand their power better, which would change the whole dynamic of the Infinity Saga in the fanfiction world. It would be a high - stakes adventure with lots of potential for different plot twists.
One interesting aspect of Iron Man time travel fanfiction could be his attempts to prevent certain disasters. For example, he might go back in time to stop the initial attack by the Chitauri in 'The Avengers'. He could use his advanced technology to gather intelligence earlier and better prepare Earth's defenses. This would not only change the course of that battle but also potentially prevent future threats that emerged as a result of that initial invasion.
Another idea is that an evil Iron Man could create clones of himself to do his bidding. These clones could be used to infiltrate different organizations, including S.H.I.E.L.D. or Stark Industries itself. It would add an element of mystery and paranoia to the story.
One of the favorite scenes in Iron Man 3 Pepper and Tony fanfictions is when Tony shows Pepper his latest Iron Man suit upgrade. He's like a kid showing off his new toy, and Pepper's reaction can range from amused to impressed. It's a sweet moment that shows their closeness and how much Tony values Pepper's opinion.
For Thor, it might be the action scenes where Iron Man is flying around and shooting things. He'd probably enjoy the display of power. Natasha might like the scenes where Tony is being clever and outsmarting his enemies with his technology.
Another could be a story where Iron Man mentors Spider - Man in the world of high - tech gadgetry. Spider - Man might be having trouble with his web - shooters, and Iron Man helps him upgrade them to be more efficient and versatile. This could also lead to some humorous moments as Spider - Man tries to adapt to the new tech.
Perhaps a story where Loki steals some of Iron Man's technology to enhance his own magic. Iron Man then has to track Loki down. Along the way, they both realize they have more in common than they thought, like their over - confidence and intelligence.
In some fanfictions, there might be a storyline where Iron Man and Ultron merge their consciousnesses. This could happen due to a freak accident in a battle. As a result, they have to learn to co - exist and control the combined power. It creates a very unique situation where the genius of Iron Man and the raw power of Ultron are united, and they have to figure out how to use it for good while also dealing with the internal conflict of two very different minds in one body.
Another storyline could involve Naruto having to adapt to the high - tech nature of the armor. He's used to his chakra - based techniques, so learning how to operate the suit's complex systems would be a challenge. Maybe he teams up with Tony Stark (in a crossover sense) who helps him master the armor. And together they face a new threat that requires both ninja skills and Iron Man - style technology to defeat.
One great storyline could be Hawkeye and Iron Man teaming up against a new, powerful villain that has technology - based powers. Their different skills, Hawkeye's archery and stealth, and Iron Man's high - tech suit, would make for an interesting dynamic in combat and strategizing.
I like the storylines where Harry tries to break free from the Goblin curse. It shows his internal struggle and his will to be a better person. It's a powerful concept that adds depth to his character.
