Other superheroes like Captain America or Thor could be popular characters in this fanfiction. They could interact with Tony Stark's daughter, perhaps mentoring her in combat or helping her understand the world of superheroes. The Hulk could also be involved, maybe in a comical or action - packed scenario.
Obviously, the daughter herself is a central character. Pepper Potts often appears as she was close to Tony Stark. Happy Hogan might also be there, as he was part of Tony's inner circle. And the Avengers like Captain America, Thor, and Black Widow could show up as they were friends or colleagues of Tony Stark.
Pepper Potts could be a common character. She might be in a position where she tries to mediate between Tony and his unwanted daughter, either trying to get Tony to be more accepting or helping the daughter understand Tony's perspective.
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.
One popular type of fanfiction could be about Tony Stark's daughter joining the Avengers. Maybe she inherits his genius and creates her own high - tech suit. She might struggle at first to be accepted by the existing Avengers, like Iron Man did. But through her skills and determination, she gradually wins them over and becomes an important part of the team.
Another idea for this fanfiction could be that Tony Stark's daughter starts as a sort of 'Avengers - in - training'. She is constantly trying to prove herself to the established members. There could be a lot of action - packed scenes where she is in dangerous situations but manages to use her wits and any skills she has learned from her father to get out of them.
One interesting plotline could be her inheriting Stark Industries and facing the challenges of living up to her father's legacy. She might have to deal with rival companies trying to take over while also trying to innovate in her own way.
Another plotline could involve the daughter dealing with the legacy of being Tony Stark's child. She could face pressure from the public and other superheroes, while also trying to carve out her own identity. She might struggle with living up to her father's reputation or trying to break free from it.
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.
One common character paired with Tony in young fanfiction is Pepper Potts. Even in his younger days, she could be shown as his assistant or someone he has a budding relationship with. Another is Rhodey. Their friendship likely started when they were young, and fanfictions often explore their early adventures together, like in the military academy. And sometimes, a young Peter Parker might be paired with a young Tony Stark, creating an interesting dynamic of mentorship and friendship before Peter becomes Spider - Man.
