One common storyline is them facing an alternate - dimension threat. Since they both come from different versions of the Spider - Verse, there could be a menace that is messing with the fabric of their universes, and they have to work together to stop it.
Perhaps they would start to have a bit of a rivalry at first. Spider Gwen is strong - willed and Spiderman has his own set of skills and ideas. They could initially clash over how to handle a situation, like dealing with a crime wave in the city. But then, as the story progresses, they would realize they work better together.
Perhaps a storyline where they get transported to an alternate dimension and have to find their way back home while also dealing with the differences in that world. In this dimension, the rules of physics or the power dynamics might be different, which creates new challenges for them. They might have to rely on each other more than ever and in the process, their relationship deepens.
One potential storyline could be a race against time. A powerful alien artifact has landed in their city and both Spiderman and Shadow want to get to it first. Spiderman wants to keep it safe from falling into the wrong hands, while Shadow believes it could be the key to achieving his own goals. Along the way, they face various obstacles and start to respect each other's abilities.
One common theme is the struggle between their superhero duties and their relationship. They have to save the city but also make time for each other. Another theme is the idea of two people with similar powers coming together. It's about how they can use their combined skills for good. And of course, there's the theme of love and attraction in the face of danger.
In a Spider Gwen and Spiderman kiss fanfiction, it could be a moment of great passion. Maybe it's a moment of celebration after they've defeated a powerful villain together. Their kiss could symbolize the deep connection they've developed through their shared experiences as superheroes.
Perhaps there's a power - stealing device in the fanfiction. It's stolen by a villain and used on the Avengers, but Gwen is immune. So the Avengers, now with reduced powers, end up fighting Gwen who is trying to get the device back. Or it could be that Gwen discovers a threat to her world that the Avengers don't believe in, and they try to stop her from taking action, leading to a conflict.
The Vulture could also be a major antagonist. His ability to fly and his sharp talons pose a great threat. Maybe he teams up with some other villains in the fanfiction to take on the two spiders at once. He could be stealing valuable items from around the city and Spider - Man and Spider - Gwen have to stop him.
The kiss in fanfiction between them is sometimes shown as a catalyst for change. It might be set against a backdrop of a city in chaos or a moment of calm. The description could involve the way their hands hold each other during the kiss, like Spiderman gently caressing Gwen's cheek while they kiss. And it could also lead to a series of events that change the course of their relationship, whether it's them becoming more open with each other about their feelings or facing new threats because their relationship is now in the spotlight.
They might start by comparing their spider - related abilities. For example, Spider Gwen could show off her unique way of swinging through the city compared to Spiderman. Then, they could team up to fight a common enemy, like the Green Goblin or Doctor Octopus. Their combined skills would make for an epic battle.
A possible plot is that Spider - Man and Spider - Gwen discover that they are related in some unexpected way through a long - lost family connection. This revelation shakes their relationship as they struggle to come to terms with it. They could also be pitted against each other by a powerful enemy who uses mind - control, and they have to break free and remember their true friendship.
