Who could be some interesting characters to include in a 'Tony Stark Undercover Boss fanfiction' aside from Tony Stark?

There could be the foster parents. Maybe they are a kind - hearted couple who try their best to understand Tony despite his quirks. Another character could be a foster sibling who is initially jealous of Tony's intelligence but later becomes his friend.

One idea could be that Tony Stark goes undercover in a small, struggling tech startup within his own company. He discovers a brilliant but overlooked engineer who has an idea that could revolutionize the whole industry. He then has to decide how to promote this person without revealing his true identity right away.

Pepper Potts could be a big help. She knows Tony so well, and she could try to jog his memory by showing him things from their past together, like pictures or mementos. Rhodey could also be there for him. He could tell Tony stories about their military days and how they became friends, which might trigger some memories.

One common character paired with him is Bruce Banner. They could be gaming buddies, with Bruce using his scientific knowledge to help Tony improve his games or vice versa. Another is Pepper Potts. She might be shown as someone who tries to get Tony to take a break from his intense gaming sessions.

Definitely Pepper Potts. She could play a big role in helping Tony with the adoption process and also be like a mother figure to the adopted child.

His parents, Howard and Maria Stark, are very common. They play important roles in shaping Tony's childhood. Jarvis, the family butler, also often appears. He could be the one to encourage Tony's scientific pursuits or keep him out of too much trouble.

Happy Hogan could also be an important character. He would be concerned about Tony's well - being and might be involved in tasks like getting Tony the things he needs during his recovery. Additionally, new characters might be introduced in the fanfiction, such as a prosthetics expert who becomes Tony's mentor in understanding and making the best use of his new prosthetic limb.

Well, Nebula herself is likely to be one of the main characters interacting with him. They might have some interesting conversations about the technology they both use or their experiences in space.

He would surely meet Black Panther. As the king of Wakanda, Black Panther would be the first and most important person Tony Stark would encounter.

Pepper Potts can also be a great addition in some of these fanfictions. Even though she's mainly related to Tony, her presence can add a different dynamic. For example, if the fanfiction is about Tony dealing with Howard's legacy, Pepper can be the voice of reason, helping Tony see things more clearly. She can also interact with the memory or apparition of Howard in some creative ways, which makes for a great read.
