Sure, Ultimate Spider-Man comics are available on Marvel Unlimited. This platform provides a comprehensive collection of various Marvel comic series, including this one.
One idea could be to explore what would happen if Spider - Man had to team up with his greatest enemies to face an even greater threat. For example, teaming up with Doctor Octopus and Green Goblin against an alien invasion. This would create a lot of interesting character dynamics as they have to put aside their differences.
Definitely Mary Jane. She's an important part of Peter's life in the comics. Her relationship with Peter can add a lot of emotional depth to the story. Whether it's a romantic angle or just her being a supportive friend.
The plot is crucial. It should be engaging and have a clear direction. Maybe it could involve a mystery that they both have to solve, like a conspiracy in the superhero world that only they can uncover together. This would keep the readers hooked as they follow the duo's investigation.
Even one of Spider - Man's fellow superhero friends might betray him. Maybe they get jealous of Spider - Man's popularity or feel that he is getting all the credit for their team's successes. This internal betrayal would add a lot of drama and conflict to the fanfiction story.
One possible fanfiction could involve Spider - Man and Captain Marvel teaming up during the Endgame battle. Maybe Spider - Man uses his agility to distract the enemy while Captain Marvel blasts them with her powerful energy. They could also have some fun banter, like Spider - Man making a joke about how Captain Marvel can fly and he has to swing around.
One possible fanfiction could be about Peter Parker using his Spider - Man abilities in a snow - covered city during a cold snap. Maybe he has to deal with villains who are taking advantage of the difficult weather conditions. For example, a villain could be using the snow and ice to create dangerous traps for the citizens, and Spider - Man has to swing through the icy streets to stop them.
