One way Stark could break free is by using his own strong willpower. He's a very determined person. He might fight against Loki's control from within his mind, gradually pushing Loki's influence out. Another way could be with the help of his friends. The Avengers might notice something is off about Stark and try to find a way to free him. For example, they could use some sort of technology or magic to disrupt Loki's hold on Stark's mind.
Stark could break free if he manages to find a flaw in Loki's mind - control technique. Since he's a genius, he could analyze the way Loki is controlling him and figure out a way to counter it. Maybe it has something to do with a frequency or a pattern that Loki is using. Once he figures it out, he can use his Iron Man suit's systems to emit something that cancels out the mind - control. He could also use his knowledge of neuroscience and his own mental defenses that he has built up over time to resist and break the control.
It's possible that Stark breaks free when Loki's own power is weakened. For instance, if the Avengers manage to steal or destroy the source of Loki's power that he is using to control Stark. Or perhaps Loki gets distracted by another threat and his focus on controlling Stark wavers. Stark, seizing this opportunity, uses his own intelligence and the latent power of the Iron Man suit to break the mind - control bond. He might also have some sort of emergency override system in his suit that he activates when he senses his mind is not his own, which helps him regain control.
It could lead to all sorts of wild and unexpected plot developments. Maybe Loki uses this control to manipulate Tony into doing things against his nature.
In fanfiction, Tony Stark and Loki often make for an interesting pairing. Their personalities are quite different. Tony is a genius inventor, a bit of a playboy, and very human in his flaws. Loki, on the other hand, is a complex Asgardian with his own motives and a penchant for mischief. Fanfiction writers might explore how their different worlds collide. Maybe Loki's magic and Tony's technology could either clash or combine in unique ways. For example, they could be forced to work together against a common enemy, leading to a begrudging respect for each other.
Yes, there are likely fanfictions with such an out - of - the - box concept. Fanfiction often explores wild and creative ideas, and the idea of Tony Stark being Loki's son is a very imaginative one. Writers in the fanfiction community might come up with various scenarios to explain how this could be possible, like some magical or alternate - reality - based reasons.
One possible plotline could be Loki using his mind control on Tony Stark to make him build a powerful weapon for him. Stark, under Loki's control, might use his advanced technology knowledge to create something that could threaten the Avengers. Another plotline could involve Loki making Stark turn against his fellow Avengers, causing chaos within the team. Maybe Stark starts acting out of character, being more aggressive and uncooperative, which makes the Avengers suspect that something is wrong.
Their interaction would be full of tension at first. Loki is a trickster and Tony is a skeptic. Loki would likely use his charm and magic to try to throw Tony off, while Tony would be using his sarcasm and intelligence to counter Loki's advances. It would be like a clash of two very different personalities, one from the world of magic and the other from the world of science and technology.
In fanfiction, their friendship could start from a mutual understanding of being outcasts in a way. Tony, a genius among humans but often not fully understood, and Loki, the adopted Asgardian with his own complex identity. They might bond over their intelligence, with Loki's magic and Tony's technology being points of fascination for each other.

Another way could be through hacking. Tony is a genius when it comes to technology. He could hack into Shield's systems and cause widespread chaos, like shutting down their communication networks, power sources, and defense mechanisms, which would ultimately lead to the destruction of Shield as an organization.
It could be about a character with a tortured mind in the context of the Tony Stark universe. Maybe it explores the psychological struggles of someone who idolizes Tony Stark but has their own inner turmoil.
Loki might interact with her in a rather mischievous way at first. He could play little tricks on her just to see her reaction, but also be secretly impressed by her intelligence, which she got from her father. For example, he might magically move her tools while she's working on a project, and then be amused when she quickly figures out how to get them back using her own smarts.
