In the 'tony thanos death fanfiction', it might be that Tony and Thanos are engaged in a mental battle as well as a physical one. Tony could try to outwit Thanos, but Thanos has some hidden power or knowledge that gives him the upper hand. Tony's death could then be a result of his overconfidence in his own intellect. Or, it could be that the other Avengers are in a desperate situation, and Tony makes a heroic move to save them all from Thanos, which unfortunately costs him his life.
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.
In a 'Tony kills Thanos' fanfiction, the plot could start with Tony being haunted by his previous failures against Thanos. He decides to go on a solo mission to study Thanos more closely. He discovers a way to disrupt Thanos' connection to the Infinity Stones. With this knowledge, he devises a plan. He lures Thanos into a trap where he has set up a device that can nullify the power of the Stones. Then, in a tense battle, Tony uses his own advanced technology and combat skills to fight Thanos without the Stones' advantage and finally manages to kill him. This could be a story of redemption for Tony, showing his determination and ingenuity in the face of seemingly insurmountable odds.
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.
Probably the other Avengers like Captain America. He could play a role in trying to save Tony or in the fight against Thanos that ultimately leads to Tony's death. Maybe Doctor Strange as well. Since he has knowledge of the future and the Infinity Stones, he might be involved in some way. He could either try to prevent Tony's death or his actions could inadvertently lead to it.
One possible reason could be to test Tony's loyalty. Thanos might want to see if Tony is truly committed to his own self - interest over protecting Peter. Another reason could be to break Tony psychologically. Tony has a father - like relationship with Peter, and forcing him to harm Peter would be a huge blow to Tony's mental state.
One possible plot could be that Harry and Tony are both merchants in a dangerous world. Master is a powerful figure who controls the market.

Well, it could be something like Thanos becomes intrigued by Loki's legs for some strange, otherworldly reason. Maybe Loki has some sort of magic or power that is centered around his legs that Thanos wants to possess or control.
Another aspect could be the emotional turmoil for the other Avengers. They would surely be scrambling to find Tony. Captain America might feel especially guilty, considering their past differences. The team would have to put aside their differences completely to rescue Tony. They might start by gathering intel on Thanos' whereabouts and formulating a plan that involves their unique skills. For example, Black Widow could use her espionage skills to infiltrate Thanos' base, while Thor could provide the brute force needed in a direct confrontation.
Maybe Peter inherits Tony's high - tech gadgets. For example, he could get access to some of Tony's Iron Man tech, which would be a huge deal. This could set him on a new path in his superhero journey, perhaps allowing him to upgrade his own suit or develop new abilities.
