One interesting scenario could be Spider - Man using Venom's powers for good in a more controlled way than Eddie Brock ever did. For example, he might use Venom's enhanced strength and agility to stop a powerful villain that the normal Spider - Man powers couldn't handle easily.
In some fanfiction, Spider - Man controlling Venom might lead to a situation where he has to deal with the moral implications of using such a powerful and sometimes violent force. He could struggle with the darker impulses that come with the Venom symbiote while still trying to use it for the greater good. This internal conflict would make for a very engaging story.
There are several scenarios. For instance, in a situation where a powerful new villain emerges with the ability to nullify Spider - Man's powers. Venom, being a different kind of entity, might be immune to that power - nullifying effect. So it protects Spider - Man by fighting this new threat. Also, if Spider - Man is trapped in a dangerous location like a collapsing building, Venom can use its strength to rescue him and keep him safe from further harm.
One interesting storyline could be Venom teaming up with Spider - Man in a Homecoming - based setting. Maybe there's a new threat in the city that they both realize they need to face together. For example, a powerful criminal organization that's using advanced technology stolen from Stark Industries. Another could be a Venom - origin story set during the time frame of Homecoming, where the symbiote's arrival on Earth and its connection to Peter Parker's world is explored in a different way than in the official comics or movies.
Well, a cool plot could be that there's a scientific experiment gone wrong that fuses Venom and Spider - Man's powers in an unexpected way. They have to figure out how to control these new combined abilities while also dealing with villains who want to steal their power source. Or perhaps Venom gets amnesia and Spider - Man has to convince him that they were once enemies but now need to work together. There could also be a story where Venom's offspring has a different relationship with Spider - Man, like it's more of an anti - hero sidekick.
Another interesting plot could be that a mad scientist creates a device that can separate Venom from his host. However, the separation goes wrong and the symbiote energy starts to spread across the city, infecting people. Spider - Man and Venom must work together to find a way to contain the energy and save the city.
One idea could be Venom and Spider - Man teaming up against a new, more powerful symbiote that threatens the city. They have to put aside their differences and use their combined powers to defeat it.
In some fanfiction, the Venom suit could give Spider - Man new abilities that he has to learn to use. Maybe he discovers he can create shadowy tendrils that can grab objects from a distance or form a protective shield. This could lead to him having to train in secret to master these powers without his friends finding out.
Well, a cool Venom and Spider - Man crossover fanfiction idea might be that there's a strange alien invasion. But this time, the symbiotes are being controlled by an even greater evil. Venom, having his own sense of justice, decides to work with Spider - Man. They start off not trusting each other much, but as they face the challenges, they learn to rely on one another. Also, perhaps Spider - Man has to deal with some of Venom's more violent tendencies during the fight.
One interesting fanfiction could be about Spider - Man and Venom teaming up to fight a new, powerful villain that neither could defeat alone. Maybe a symbiote - enhanced Green Goblin. In this story, they would have to put aside their differences and learn to work together, with Spider - Man using his agility and Venom's brute strength.
In some fanfictions, they might team up against a common enemy that requires both their unique skills. For example, a new super - villain who has the ability to hack into Iron Man's technology and also has super - strength that Spider - Man has to counter with his acrobatic fighting style. They would have to learn to work together, with Iron Man respecting Spider - Man's instincts and Spider - Man learning to trust Iron Man's strategic plans.
One interesting 'Ultimate Spider - Man Venom' fanfiction could be about Venom teaming up with Spider - Man to fight a greater evil. In this kind of story, they might put aside their differences because a powerful new villain emerges that threatens the whole city. They could combine their unique powers to take on this threat.
