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.
One possible plot could be that Tony Stark, while on a solo space exploration mission, stumbles upon the Ravagers. He initially has a tense encounter with them as they are skeptical of his motives.

Tony modifies some of his Iron Man tech with Ravager tech he discovers, creating a new and more powerful suit.
Well, perhaps the plot could start with Tony Stark coming across some ancient Norse texts about Jormungand while researching something completely unrelated. He then becomes obsessed with learning more about the Midgard Serpent. He might try to create a tech - based model of Jormungand to study its capabilities. 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.
First, you need to understand Tony Stark's character really well. Read the comics, watch the movies. Then, create an interesting original character (OC). Give your OC a unique backstory, personality traits that can interact well with Tony Stark's. Also, come up with a good plot. It could be something like your OC helping Tony Stark in a new technological project or facing a common enemy together.
In this fanfiction, the plot might be centered around Tony's journey of self - discovery as a Greek demigod. He could start having strange dreams or visions related to Greek mythology.

Along the way, he might have to choose between his life as a superhero in the public eye and his new life as a demigod, which has its own set of rules and responsibilities that he has to learn and abide by.
The plot could revolve around Tony Stark's discovery that the mutant registration act is being misused by some powerful and corrupt individuals.

Maybe in a fanfiction, there is a cursed ballet. Tony Stark and Loki are both drawn to it for different reasons. Tony because of his love for all things unique and Loki because he senses dark magic.

As they work together, they form an unlikely bond.
Well, perhaps the plot could involve Tony Stark's quest to collect all the Infinity Stones for some noble purpose. Maybe he wants to use their power to prevent a greater threat to the universe than Thanos ever was.
