One great piece of Mary Jane and Tony Stark fanfiction is 'A Meeting of Minds'. In it, Mary Jane accidentally stumbles into one of Stark's high - tech labs. Their interactions are really interesting as they come from different worlds within the Marvel universe. Stark is all about technology and MJ has her own charm and street - smartness. Another good one is 'Unlikely Allies' where they team up to solve a mystery in New York that involves both high - tech threats and some more down - to - earth villains. It shows how their different skills can complement each other.
I really liked 'MJ and Stark: A Different Kind of Team'. This fanfiction delves into how Mary Jane, with her experience in the entertainment industry, can help Tony Stark with his public image. Meanwhile, Stark introduces MJ to a world of high - tech gadgets and advanced science. Their banter is really well - written, and the story builds up their relationship gradually. It's not a typical superhero - saves - the - day kind of story, but more about the development of their friendship and mutual respect.
