One idea could be that Spider - Man's cosmic powers give him the ability to manipulate energy on a cosmic scale. He could use this power to create shields or blast enemies. Also, his web - shooting ability might be enhanced, allowing him to shoot webs that can traverse the vastness of space and attach to celestial bodies.
In some fanfictions, Spider - Man might gain the ability to teleport across the cosmos. This could lead to him exploring different galaxies and encountering alien species that are both friendly and hostile. He could use his spider - sense in new ways, like detecting threats from across the universe.
One interesting plot could be Cosmic Spider - Man traveling to different dimensions within the cosmos and encountering alternate versions of himself. This could lead to self - discovery and learning new powers.
If Spider - Man kept the cosmic powers in fanfiction, he would likely face new challenges. With great power comes great responsibility, and these cosmic powers might attract more dangerous enemies. He could also struggle with controlling the powers at first. His relationships with his friends and family might change as they try to adjust to this new, super - powered version of him.
His sense of humor might change. While he still has his quippy nature, it could be more cosmic - themed. For example, he might make jokes about black holes or alien cultures. His empathy could also expand as he meets different beings from across the universe and understands their plights.
One idea could be exploring the backstories of the different Spider - People in more detail. For example, how did Peni Parker really come to terms with her role as Spider - Woman in her own dimension. Another could be a crossover within the Spider - Verse, like what if Miles Morales and Gwen Stacy teamed up to face a new villain that was causing chaos across multiple dimensions.
There could be a lot of drama in the fanfiction related to the spider armor. For example, the public might react differently to this new armored version of Spider - Man. Some might see it as a sign of him becoming too militarized, while others might see it as a necessary upgrade. The armor could also be a target for villains who want to steal its technology for their own evil purposes.
One idea could be exploring the backstories of the different Spider - People more in - depth. For example, Peni Parker's relationship with her father and how it influenced her becoming Spider - Woman. Another could be a story where all the Spider - People have to team up against a new villain that is specifically targeting their multiverse connection. Maybe a villain who can disrupt the portals between their worlds.
One idea could be exploring the different Spider - People's home universes in more detail. For example, showing what Miles Morales' daily life in his universe was like before becoming Spider - Man. Another could be a team - up between Miles and an older, more experienced Spider - Person from a different universe to face a new and powerful villain.
Maybe a fanfiction where all the Spider - Men and Women from different spider - verses team up to fight a common enemy that threatens all of their universes. It could be a powerful cosmic entity that is consuming the multiverse, and they have to combine their unique skills and knowledge to stop it. This would allow for a lot of cool interactions between the different characters.
Perhaps there's a fanfiction where Spider Man and Spider Gwen accidentally swap powers. They have to learn how to use each other's abilities to fight crime. This would lead to some really funny and also challenging situations as they get used to different ways of web - slinging and sensing danger.
Some fanfictions give Spider - Man the power to heal himself much faster. This means that even after a really tough fight, he can get back on his feet in no time. In addition, he might have the power to fly using his webs in a more efficient way, like creating a sort of web - glider that can carry him long distances. There could also be a power where he can project his thoughts into the minds of others, which would be useful for both communication and misdirection.
