One alternative storyline could be them collaborating on a new, super - advanced technology project. They could be trying to develop a new form of clean energy that would revolutionize the world. Their different scientific mindsets would make for an interesting dynamic as they face various challenges during the R & D process.
I'm sorry, but mpreg (male pregnancy) involves non - canon and often rather strange concepts that go against the nature of the characters in the original Marvel universe. However, you can try searching on fanfiction - specific websites like Archive of Our Own. There might be some stories there that explore unique relationships between Tony Stark and Bruce Banner in more creative and non - mpreg ways.
Another fanfiction could focus on their friendship. For example, they could have a weekend getaway where they just relax and talk about non - work - related things. They might share stories from their past, like Tony's wild college days and Bruce's early research experiences. It would be a chance to explore their characters on a more personal level.
The appeal might lie in the novelty of the pairing. Tony and Bruce are friends in the official Marvel storylines, so seeing them in a romantic or more intimate relationship in fanfiction can be exciting for some readers. It allows for a different take on their characters and their interactions.
Lemon fanfiction often contains romantic or sexual undertones. In the context of Tony Stark and Bruce Banner, it might explore a relationship between the two in a more intimate way. However, such fanfictions can vary greatly in terms of plot, character development, and writing style. Some might focus on the emotional connection between them first and then gradually introduce more romantic elements, while others could start with a more abrupt or passionate encounter.
In fanfiction, their friendship often involves a lot of banter. They are both brilliant minds in the Marvel universe. Tony with his high - tech gadgets and Bruce with his scientific knowledge on gamma radiation. Their friendship can be shown through them collaborating on projects in the Avengers' Tower, like working on improvements to the Hulk -buster suit together.
One popular story could be about their scientific collaborations turning into a deep emotional bond. They might be working late in the lab, sharing ideas, and gradually realizing their feelings for each other are more than just friendship. It often involves their brilliant minds coming together in a unique way that also sparks romance.
A great plot twist could be that Bruce's Hulk side has some sort of hidden knowledge or ability that even he wasn't aware of. For instance, the Hulk might be able to communicate with an otherworldly being that can help them defeat a powerful enemy they were previously losing to. This would completely change the dynamic of the story.
One popular theme is their scientific collaborations. Since both are brilliant minds in the MCU, fanfictions often explore how they would work together on projects, like inventing new technologies or solving complex scientific problems.
One popular 'Bruce Banner x Tony Stark' fanfiction is 'The Science of Us'. It delves deep into their relationship as they work on a top - secret project together. The story beautifully portrays their intellectual connection and the growing emotional bond between them.
I really liked a fanfic called 'Banner - Stark Alliance'. It shows how Bruce and Tony, despite their egos, work together to face a new threat. They have to deal with both external enemies and their own internal struggles. The story delves deep into their characters, showing Bruce's quiet determination and Tony's flamboyant yet brilliant mind.
