You can't really 'watch' fanfiction in the traditional sense like you do a movie. Fanfiction is written text. However, you can find Spider - Man: Into the Spider - Verse fanfiction on various fanfiction websites such as Archive of Our Own (AO3) or FanFiction.net. Just search for the relevant tags related to the movie on these platforms.
One possible fanfiction could be about Venom finding its way into the Spider - Verse. Maybe it starts when a symbiote experiment in an alternate dimension goes wrong and Venom is accidentally sent into the Spider - Verse. He could encounter different versions of Spider - Man and create chaos as he tries to find a way back to his own dimension. He might initially be seen as a threat by the Spider - People, but as the story progresses, they could realize that he's just lost and confused.
One idea could be a story where Miles Morales has to team up with an alternate version of himself from a dimension where he never became Spider - Man. They have to overcome their differences and learn from each other to stop a new villain that is threatening all the spider - verse.
In Spider - Man Into the Spider - Verse story, it begins with Miles Morales. He's a young boy with his own set of insecurities and dreams. When he gains his spider - like abilities, he has to learn to control them quickly. The story takes a wild turn when the multiverse is involved. There are various versions of Spider - Man, each with their own unique styles and personalities. For example, there's a Spider - Man who is a noir - style detective. Kingpin's actions disrupt the balance of the multiverse. Miles, along with the other Spider - People, has to face many challenges, not only in fighting Kingpin but also in understanding and accepting his new role as a Spider - Man. It's a story full of action, humor, and heart - warming moments as Miles grows into his new identity.

In the movie, Gwen's story is quite interesting. She comes from her own dimension where she has to face various threats. She has a unique look with her white - and - pink costume. Gwen's relationship with Miles is complex. She serves as a sort of mentor and friend to him. She's been through a lot in her world, including the loss of someone close, which has shaped her into the tough and determined Spider - Woman we see in the movie.
