Another possibility is that the female guide is an alien. She has advanced knowledge of the cosmos and guides Tony in his exploration of outer space. She could introduce him to new alien technologies and cultures. Their interactions would be a blend of scientific discovery and cultural clashes, making for an exciting fanfiction story.
A female guide could also be a spy. She infiltrates Stark Industries to guide Tony in matters of national security. She might be from a secret agency and has inside information about threats against Tony and his technology. This would lead to a lot of action - packed scenes and a different kind of relationship between her and Tony, full of mistrust at first and then cooperation.
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.
A female guide in Tony Stark fanfiction could be a really interesting character. She might be a fellow scientist who helps Tony in his projects. For example, she could be an expert in a specific area of technology that Tony is less familiar with, like advanced biotech. This could lead to some great storylines where they work together to create something amazing, all while having some flirty banter typical of Tony's character.
One common character paired with him could be Pepper Potts. Their relationship could be explored in a new light with Tony having psionic powers. Maybe Pepper has to deal with a more powerful and sometimes unpredictable Tony.
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.
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.
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.
The therapist is a common character in these fanfictions. They can be an original character created just for the story, or sometimes it could be an existing character from the Marvel universe given a new role as a therapist. For example, Dr. Strange could be reimagined as Tony's therapist in some fanfictions. Another common character could be Rhodey. He's Tony's friend and might be involved in encouraging Tony to attend therapy or be there for him during the process.
Tony Stark himself is, of course, the central character. Often, Pepper Potts might make an appearance, either trying to get him out or communicating with him from the outside. Rhodey could also be a common character, maybe working on a military - backed plan to free Tony.
