What could be the possible plot in a 'Tony kills Thanos' fanfiction?

Well, one possibility could be that Tony sacrifices himself in a final battle against Thanos. Maybe he uses some new, untested technology that ultimately drains his life force but also manages to defeat Thanos. Another idea could be that Thanos, in a moment of unexpected mercy, spares Tony's life initially but then something goes wrong in the aftermath, leading to Tony's death. For example, perhaps the Infinity Stones' power backlash affects Tony in a way that kills him.

Yes, there are likely fanfictions out there where Tony kills Thanos. The Marvel universe has a huge fan base, and fans often create alternative storylines. Some might explore this scenario to give a different take on the Infinity War and Endgame stories.

One possibility is that there could be a huge ideological rift between them. Maybe Steve discovers some dark secret of Tony's that he believes endangers the world in a way that can't be resolved through normal means, leading to the extreme act of killing him.

One possible plotline could be Thanos trying to win Tony over while still being true to his villainous ways. Another could be Tony using Thanos' feelings to his advantage in a battle.

One possible plot twist could be that Peter uses his intelligence rather than just his powers to defeat Thanos. Maybe he discovers a weakness in Thanos' armor or a flaw in his plan that no one else has noticed. For example, he could find out that Thanos' Infinity Gauntlet has a time - limited recharge period for its powerful snaps, and he uses this knowledge to his advantage at a crucial moment.

One possible plot could be that Peter Parker discovers a new power within himself that gives him the edge to take on Thanos. Maybe it's a power related to the Time Stone that he manages to manipulate in a way that Thanos can't counter.

One consequence could be that Peter Quill Parker becomes a hero. People all over the universe might look up to him. But he may also face some jealousy or envy from other powerful beings.

One reason could be to explore the extreme consequences of their ideological differences. In the official story, they had disputes over things like the Sokovia Accords. In fanfiction, this could be pushed to the limit, leading to Tony taking Steve's life.

In some fanfictions, Tony Stark kills Thanos by outsmarting him in a battle of wits. He could set up a series of elaborate traps and illusions that deceive Thanos into a vulnerable position.

Or, Stark could use his Iron Man suits in a very creative way. He could send a swarm of mini - suits to attack Thanos from all directions, overwhelming him and finally finding a way to kill him.
