I'm not sure who Tony specifically is in this fanfiction without reading it. It could be an original character created by the author, or perhaps a reimagined version of a known character in a particular fictional universe.
The 'Merchant of Death' concept probably means that Tony is involved in activities related to death in a commercial way. For example, he might be selling things that can cause death, such as weapons or poisons.
One possible fanfiction plot could be that Tony sacrifices himself to save a fellow agent. In the story, he might be on a dangerous mission where the enemy has the upper hand. Instead of letting his teammate get killed, he jumps in front of a bullet or takes on a dangerous task that ultimately costs him his life. His death could then have a profound impact on the other characters, leading to a series of events where they struggle to come to terms with their loss and also find a way to honor his memory.
Yes, there are quite a few. Some explore the impact of his death on the other Avengers, like how they deal with the loss and the changes it brings to the team dynamics.
In many Avengers fanfictions where Tony dies, it's often a heart - wrenching scenario. One common plot is that he sacrifices himself heroically to save the world one last time, much like in the movies. His death leaves a huge void in the Avengers team, and his friends are left to deal with the grief and the aftermath. It makes for some very emotional and poignant stories as his character was so central to the Avengers' narrative.
Another theme is self - discovery. Tony realizes that his identity as a weapons - maker isn't all he wants to be. He starts to explore other aspects of himself, like his ability to be a true hero and protector. In some fanfictions, he discovers new values and beliefs that change his perspective on life. For example, he might start to value human life more than profits from weapons sales. This self - discovery often goes hand in hand with his journey of redemption.
One type of Tony Dinozzo death fanfiction I recall is where his death is a result of an old enemy coming back for revenge. These stories often delve into the emotional aftermath for the other characters. They can be quite heart - wrenching as they show how his death affects Gibbs, Ziva, and the rest of the team. You might also find some that explore the idea of his death being preventable if certain events had played out differently.
Tony's death in Avengers fanfiction can be portrayed in various ways. Sometimes it's a slow and painful death due to radiation exposure from his arc reactor. This gives the other characters time to interact with him in his final days, and there are a lot of emotional goodbyes. It also shows his strength as he endures the pain while still trying to offer advice to his friends.
Perhaps Tony discovers his true identity as Death's son gradually. Along the way, he could face challenges from other supernatural beings who either fear or envy his connection to Death. His relationships with his friends and family would also be severely tested as he tries to keep this secret and navigate his new reality.
