Perhaps the plot could involve a multiverse scenario. Peter Parker from one universe and Mystique from another are brought together by some cosmic event. They have to overcome the differences in their worlds and their own personal natures. Mystique has to learn to trust Peter completely, and Peter has to accept Mystique's shape - shifting abilities. They get married as a symbol of their union against all odds.
The plot might start with Mystique being on a mission that somehow crosses paths with Peter Parker. She initially uses him for her own gain but then develops real feelings. Peter, being the kind - hearted person he is, forgives her. They start dating secretly, and as their relationship deepens, they decide to get married. However, they face opposition from both the X - Men (because of Mystique's past actions) and some of Peter's allies in the superhero community who don't trust Mystique.
One possible plot could be that Mystique, in her quest to understand humanity better, decides to infiltrate Peter Parker's life. As she spends time with him as different people, she starts to truly fall for him. Peter, on the other hand, is initially confused by her ever - changing appearances but then realizes he loves the person inside. They face many challenges together, like Mystique's past coming back to haunt her and Peter trying to keep their relationship a secret from his superhero friends.
Well, the plot might involve Nebula coming to Earth for some reason, maybe to seek help against a new threat in the galaxy. Peter Parker, with his sense of responsibility, gets involved. They start to train together and during this time, they discover they have a lot in common in terms of their determination and the losses they've faced. This mutual understanding blossoms into love, and they get married. Their wedding could be a grand affair with Avengers and Guardians of the Galaxy in attendance, symbolizing the union of Earth's heroes and the cosmos.
One possible plot could be that Peter Parker, while still being Spider - Man, meets Tala in his civilian life. They start as friends, gradually fall in love. Tala discovers Peter's secret identity and accepts him wholeheartedly. Their wedding could be a small, intimate affair with just their closest friends and family, like Ned and MJ. However, Peter has to deal with some last - minute villain threats that he manages to overcome just in time to say 'I do' to Tala.
One possible plot could be that Peter Parker and Elektra meet in a rather unexpected situation. Maybe Elektra is on a mission in New York and crosses paths with Spider - Man (Peter Parker). They initially clash due to their different fighting styles and moral compasses. But as they get to know each other better, they start to fall in love. Their relationship develops in secret at first, as they both have their own lives and secrets to keep. Eventually, they decide to get married, but have to face the challenges of combining their two very different worlds. Peter's friends and family in Queens might be shocked at his choice, and Elektra's past associations might come back to haunt them.
Perhaps the plot starts with Catwoman stealing something important that Peter Parker is also after. They cross paths and instead of fighting right away, they start talking. This leads to a series of adventures together where they realize they have a deep connection. When they decide to get married, they have to plan it in secret because of their different reputations. But as the news gets out, they have to face both the superhero community and the criminal underworld, with some trying to stop the wedding and others trying to use it for their own gain.
One possible plot could be that Peter Parker and Shuri meet at a scientific conference. They initially bond over their shared love for technology and innovation. As they start working on a project together, they realize they have deeper feelings for each other. Their relationship faces challenges like cultural differences between Wakanda and New York. But through mutual understanding and support, they decide to get married. Their wedding could be a grand affair with Avengers and Wakandan royalty in attendance.
There would be the challenge of public perception. Peter Parker is a well - known superhero, and Mystique has a reputation as a shape - shifter who has been on both sides of the law. Their relationship would be under intense scrutiny. The superhero community might not accept their union, fearing that Mystique could be using Peter for some ulterior motive. Additionally, Mystique's powers could cause problems in their relationship. For example, she might accidentally shift during an argument or a moment of stress, which could be very disconcerting for Peter.
One possible plot could be that they meet in a situation where they have to team up against a common enemy. During their time together, they start to understand each other on a deeper level. Peter's sense of responsibility and Emma's strong will attract them to one another. Eventually, they fall in love and decide to get married. Their wedding could be a grand affair with many superheroes in attendance, but also a target for villains who want to disrupt it.
One possible plot could be that they meet in a multiverse - type situation. Peter, being from his world of superheroes, and Red Sonja from her more sword - and - sorcery realm. They are initially at odds due to their different fighting styles and values. But as they face a common enemy, perhaps a powerful sorcerer who wants to conquer both their worlds, they start to respect each other. Their relationship gradually turns into love and they decide to get married to combine their strengths and protect both their worlds.
One possible plot twist could be that Mystic has a secret identity or past that threatens their marriage. For example, she might be related to one of Peter Parker's enemies without knowing it. Another could be that a powerful villain tries to use their marriage as a way to get to Spider - Man. Maybe they put a spell on Mystic to make her turn against Peter.
One possible plot twist could be that Amora's Asgardian heritage causes problems. Maybe some Asgardian law or custom forbids her from marrying a mortal like Peter Parker. For example, the Asgardian council could oppose the union and send someone to stop it, creating a conflict for the couple to overcome.
