I think Rhodey is often a great character in 'Tony Stark Fights Thanos' fanfiction. He's Tony's friend and he can add a lot of emotional depth to the story. He might be the one who tries to talk Tony out of some risky plans but also stands by him in the end. Also, Nebula can be really well - written. Since she has her own vendetta against Thanos, she can team up with Tony in interesting ways. She can bring her knowledge of Thanos' habits and weaknesses to the table.
Tony Stark himself is often very well - written in these fanfictions. Writers can really explore his genius, his determination, and his flaws. Another great character can be Pepper Potts. In some fanfictions, she plays a crucial role in helping Tony, like providing him with moral support or even getting involved in the fight in some way. And of course, Thanos. A well - written Thanos in these fanfictions is truly menacing, with his complex motives and powerful abilities clearly shown.
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.
Well, in some 'Tony Stark Fights Thanos' fanfiction, there's a plot where Tony manages to hack into Thanos' mind through some super - advanced tech he's developed. This allows him to create illusions in Thanos' head, confusing him during battle. Also, a common plot is that Tony sacrifices himself in a very heroic way. He uses all his suit's power and some experimental tech to send Thanos into a different dimension or something like that, saving the universe at the cost of his own life.
I think in many fanfictions, the character of Tony Stark stands out. His charisma, his sense of humor, and his determination are really well - captured. And Jarvis is also very well - written in terms of his calmness and his unwavering support for Stark. He's like the voice of reason in many stories, which makes him a very interesting character.
In this scenario, it would be a complete shocker. Tony Stark is a hero, and Thanos is a villain. If he were to join Thanos, it might be because Thanos somehow convinced him that his plan was for the greater good. Maybe Thanos showed him a future where overpopulation and resource depletion were so bad that his 'snap' was the only solution. But this would go against everything Stark stands for, so it would be a very complex and dark turn for his character.
In many Tony Stark and Ultron fanfictions, Pepper Potts can be a great character. She provides a human connection for Tony and can often be the voice of reason. Also, Captain America can be a great addition. His moral compass clashes with Tony's more pragmatic approach, especially when it comes to dealing with Ultron. This creates great drama and tension in the stories.
Pepper Potts could be great. Even if Tony is deaged, she could still be his caretaker or friend in a different way. She could see his potential and help him navigate the world as a deaged version of himself. Another good character would be Rhodey. He could be like an older brother figure, protecting Tony and also being amazed at his young - but - still - brilliant self.
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.
Bruce Banner might be a good match as well. Since he's a scientist like Tony, his relationship with Tony's sister could involve a lot of scientific discussions. And with his struggle with the Hulk, she could be the one to help him find more balance in his life, which would be a really heartwarming and engaging plot in the fanfiction.
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.
Thanos is extremely powerful with the Infinity Stones. However, Tony Stark has a history of coming up with solutions against seemingly unbeatable odds. In a fanfiction, the author might give Stark an edge by having him discover a hidden weakness of Thanos or develop a new weapon that can neutralize the Stones' power. So, it's possible for Stark to win if the story is written in a way that emphasizes his ingenuity.
