A great plot could involve the OC being a journalist. They are assigned to do a story on Tony Stark. At first, Tony is reluctant to cooperate, but the OC's tenacity and genuine interest in his work as Iron Man make him change his mind. As they spend more time together for the story, they become friends. Then, they end up using their combined skills to expose a conspiracy within the government that is targeting superheroes.
Developing the OC in a Tony Stark best friend fanfiction requires a multi - faceted approach. Their goals and dreams are important. If they want to make the world a better place through their inventions, it sets the tone for their character. Their flaws are equally crucial. Maybe they are a bit too idealistic, which sometimes causes problems in their friendship with Tony. Their hobbies can also be a part of their character development. If they love old - fashioned vinyl records, it shows a side of them that is different from the high - tech world of Tony. Interactions with other characters in the Marvel universe, not just Tony, can further develop the OC.
A good fanfiction in this regard should have a strong bond between Tony and his best friend. For example, they should be able to understand each other without many words. Their interactions should feel natural, like real friends.

As he delves deeper, he discovers some secrets about Norse magic that could potentially be applied to his technology, leading to a whole new level of Iron Man upgrades.
