Well, they might start by comparing their high - tech gadgets. Tony would show off his Iron Man suit with all its amazing features, while Bruce would talk about the tech in his Batmobile and other gear. Then, they could end up working together on a project to fight a common enemy, combining Stark's genius in energy and robotics with Wayne's skills in detective work and combat strategy.
In such a fanfiction, they might start by sizing each other up. Bruce would be intrigued by Tony's high - tech gadgets and playboy lifestyle, while Tony would be curious about Bruce's dual identity and his more brooding nature. They could end up collaborating on a project, perhaps something to do with improving Gotham's infrastructure using Stark technology.
One possible storyline is a competition between them. They could bet on who can solve a particular global threat faster. Bruce would use his detective skills and resources in Gotham, while Tony would rely on his Stark tech. Another could be that they get framed for a crime together and have to work together to clear their names while also finding the real culprit.
It depends on the situation. If it's about technology, Tony Stark would likely be more dominant. His knowledge of advanced robotics and energy sources is vast. But when it comes to stealth and understanding the criminal mind, Bruce Wayne would take the lead.
One great fanfiction could be 'Alliance of Titans'. In this story, Bruce Wayne and Tony Stark meet at a high - tech expo. They initially clash due to their different approaches but soon realize they can learn from each other. Their friendship blossoms as they face a common enemy who is stealing high - tech gadgets from both Wayne Enterprises and Stark Industries. Another one is 'The Billionaire Bond'. Here, they are brought together by a mysterious organization that wants to use their combined wealth and intelligence for their own evil purposes. Bruce and Tony must work together to outwit the bad guys and in the process, their friendship deepens.
Fanfiction.net might also have some. However, the tagging system there can be a bit less precise compared to AO3. But it's still worth a look. Browse through the superhero or Marvel/DC crossover sections and keep an eye out for the specific pairing.
In fanfiction, they often start off as rivals. Tony Stark, with his flamboyant and open - about - his - identity style, clashes with Bruce Wayne's more secretive and brooding approach. But as the story progresses, they usually find common ground in their intelligence and drive to protect the world.
