Fanfiction.net is another option. It has been around for a long time and has a large number of Tony Stark fanfictions. You can sort through the romance category and look for the ones with high ratings and lots of reviews. Additionally, Tumblr can be a good source. There are many fanfic rec blogs that might feature some great Tony Stark romance stories.
Tony Stark and Pepper Potts is a very popular pairing. In the official Marvel universe, they have a long - standing relationship, and fanfiction often expands on this. Another popular one is Tony Stark and Natasha Romanoff. Their personalities are so different that it creates an interesting dynamic in a romantic relationship.
There's also 'Tony Stark and Jarvis: A Bond Beyond Tech'. This one focuses on the emotional bond between them. It shows how Tony has come to rely on Jarvis not just for his intelligence but also for the comfort of having someone always there. It has some heart - warming moments where they have deep conversations, and it really makes you appreciate their unique relationship.
One great Spiderman and Tony Stark fanfiction is 'The Stark Internship'. It shows how Peter Parker's relationship with Tony develops in a really cool way. They go on adventures together and Tony acts as a mentor to Peter.
One great 'Bell and Tony Stark fanfiction' is 'Stark's Unlikely Ally'. In this story, Bell, a character with unique abilities, stumbles into Tony Stark's world. The story is exciting as it shows how Bell's naivete contrasts with Stark's high - tech sophistication. It has great character development and some really cool action scenes where Bell's powers and Stark's Iron Man suit work together in unexpected ways.
Well, 'Tony Stark: The Mutant Avenger' is quite interesting. In this fanfiction, Tony discovers his mutant powers during a lab accident. It shows his struggle to control these new powers while still being Iron Man. There are also some really cool fight scenes where he uses his mutant abilities in combination with his high - tech gadgets. And then there's 'Mutant Tech - Tony Stark's New Era' which delves into how his mutant status changes his approach to technology and his relationships with the other Avengers.
Well, I really like the fanfiction 'Tony Stark's Ultimate Sacrifice'. It's a heart - wrenching story where Tony has to make a huge sacrifice to save the Avengers and the world. The way it's written really captures the essence of his character. 'Avengers: Tony's Clone Dilemma' is also quite engaging. Here, a clone of Tony is created and the Avengers have to figure out if it's friend or foe. It plays with the idea of identity and loyalty. And 'The Iron Man and the Alien Alliance' is a story where Tony teams up with an alien race to help the Avengers in a fight against a common enemy. It has some really cool alien technology and battle scenes.
Pepper Potts can also be a great addition in some of these fanfictions. Even though she's mainly related to Tony, her presence can add a different dynamic. For example, if the fanfiction is about Tony dealing with Howard's legacy, Pepper can be the voice of reason, helping Tony see things more clearly. She can also interact with the memory or apparition of Howard in some creative ways, which makes for a great read.
One of the best moments is often when they have deep conversations about their respective roles and the nature of the universe. In 'The Philosophical Avengers' fanfic, they sit down and discuss how science and magic are two sides of the same coin. This kind of moment adds depth to their relationship and makes the fanfiction more than just action - packed stories.
One great fanfiction is 'The Iron Spider'. It shows a deep bond between Peter and Tony as Tony mentors Peter in a very detailed and emotional way. Peter's growth under Tony's guidance is really well - written.
