One interesting concept could be that MJ's Spider - Woman identity is initially a secret from Peter. She starts fighting crime on her own, and her methods are more unorthodox compared to Peter. When Peter finally discovers her identity, there's a bit of a conflict as he feels she should have told him. But then they realize that together they can be a more effective force against crime. Their relationship then takes on a new dynamic, with MJ being more of an equal in the superhero world.
Well, an idea could be that MJ's powers are different from Peter's. Maybe she has the ability to communicate with spiders, which gives them an edge in fighting crime. For example, she can call upon swarms of spiders to immobilize villains. And this unique power also causes some friction between her and Peter at first, as he's not used to this new way of fighting crime.
Another idea is that MJ becomes Spider - Woman due to an experiment gone wrong at Oscorp. Peter is initially against her becoming a superhero, fearing for her safety. But MJ is a strong - willed character. She uses her new - found powers to expose some corporate secrets at Oscorp that are endangering the city. As she does this, she and Peter's relationship is tested, but in the end, they become stronger as a couple and as superhero partners.
In a fanfic like this, MJ might get her powers in a freak accident. Peter, being Spider - Man, is hesitant at first about MJ joining him in the superhero world. But MJ is determined. She creates her own Spider - Woman costume and starts patrolling the city on her own. Eventually, Peter realizes he can't stop her and they start working as a duo, with their relationship evolving into a more equal partnership.
One possible plot could be that MJ discovers she has powers and becomes Spider - Woman. Peter is both proud and a bit worried as he wants to protect her. They could team up to fight a new villain in New York. MJ might struggle with keeping her identity a secret from her friends and family, just like Peter did when he first became Spider - Man.
Their relationship would become more complex. Peter would now have to see MJ not just as his girlfriend but also as a fellow superhero. He might be overly protective at times. MJ, on the other hand, would demand more respect in their relationship as an equal in the superhero world.
One great Mary Jane x Peter Parker fanfiction is 'The City's Heroes'. It beautifully captures their relationship, showing how Mary Jane supports Peter in his Spider - Man duties. Another one could be 'Love in the Web', which delves deep into their emotional connection. There are also many on popular fanfiction websites like Archive of Our Own.
Perhaps there's a plot where an alien symbiote attaches itself to Mary Jane instead of Peter. She starts to develop strange powers and a more aggressive personality. Peter has to figure out how to save her from the symbiote's control. This would put a strain on their relationship as Mary Jane struggles with the new - found power and Peter tries to be the hero she needs.
Love and support is a very common theme. MJ is often shown as a pillar of strength for Peter, and he in turn gives her a sense of adventure. For example, in many fanfics, MJ stands by Peter during his tough times as Spider - Man, whether it's dealing with a powerful villain or his own self - doubts.

Another idea is MJ discovers Peter's secret identity in a really unexpected way, like when she accidentally stumbles upon his Spider - Man gear while looking for a book in his room.
