Another possibility is that Peter stays calm and tries to gather information. He knows that knowledge is power. So while in captivity, he might be observing Thanos, his minions, and his lair. This way, when the rescue comes, he can provide useful information to his allies.
Peter would probably be scared at first. He's just a kid, after all, and being kidnapped by a powerful being like Thanos is terrifying. But he would also be defiant. He has a strong sense of responsibility, so he might try to find a way to escape on his own.
In the fanfiction, Peter Quill Parker might have some new powers or gadgets that give him the edge. He could have studied Thanos' fighting patterns and found a way to counter them. Also, his quick thinking and ability to improvise in tough situations would play a big role. He might even use his charm to get close to Thanos and then strike when he least expects it.
Peter would likely be defiant. He has a strong moral compass and wouldn't easily give in to Osborn's demands. He'd probably try to find a way to escape right away, using his spider - abilities like climbing walls and his super strength to break free from any restraints.
Well, it could also lead to a rescue mission. The Avengers or other superheroes might find out about Peter's kidnapping. They would then come together to form a plan to rescue him. This could involve a lot of strategizing and fighting against Thanos' forces.
Since Peter is Spider - Man, he has to be careful not to use his powers and reveal his identity. So he might just try to defend himself in a non - superhuman way, like using his quick reflexes to dodge Flash's blows as much as possible while trying to calm Flash down verbally.
On the other hand, Stiles is also known for his quick thinking. He might start to try and bargain with Peter. He could offer to help Peter in some way if Peter lets him go. For example, if there's a problem in the supernatural community that Peter is facing, Stiles could say he'll use his human ingenuity to solve it. Also, Stiles could be angry. He might start shouting at Peter, calling him out on his actions, and trying to make Peter see how wrong this is.
Peter will probably be very confused at first. He's used to being part of the team, and suddenly being hunted by them is a huge shock. He might try to talk to them to clear up any misunderstandings.
Peter could use his agility. Since he's super - agile, he can dodge Thanos' attacks easily. Then, when Thanos is off - guard, Peter can strike. For instance, he can web up Thanos' hands so he can't use the Infinity Gauntlet properly.
In a Thanos and Peter Parker fanfiction, it could be set in an alternate universe where Thanos has already won. Peter Parker is one of the few remaining heroes. He has to go undercover and try to find a way to reverse what Thanos has done. Peter uses his street - smart skills from Queens to blend in among the survivors and slowly gather information about Thanos' weaknesses. He might even form an unlikely alliance with some of Thanos' minions who have second thoughts about their master's actions.

Peter usually blushes a lot. Since he's a shy and somewhat awkward teenager, his face turns bright red when the Avengers embarrass him. He might stutter while trying to defend himself or come up with an excuse.
