In the fanfiction where Spider - Man is captured by Venom, he could be used as a bargaining chip. Venom might try to use Spider - Man to get something from the Avengers or other superheroes. Spider - Man would be constantly thinking of ways to break free. He might also try to communicate with Venom, to understand what makes him so angry and vengeful, and in the process, find a weakness to exploit. It would be a battle of wills as much as a physical struggle.
Well, in such a fanfiction, the Avengers might capture Spider - Man thinking he's a threat for some misinformation. They could lock him up in the Avengers Tower. Maybe Iron Man would be the one to first approach him and try to figure out what's going on while Spider - Man is all confused and trying to prove his innocence.
In fanfiction, if Spider - Man turns into Venom, he might initially struggle with the new, darker impulses. Venom's symbiotic nature could make him more aggressive. He could find it hard to control his actions, like being more prone to using excessive force against villains. His relationships would also change. His friends might be scared of him at first, and he'd have to prove that he's still the good guy inside.
It could lead to some really intense battles and power shifts. Spider-Man might have new abilities and face even tougher challenges.
Well, it might show Spider - Man struggling not only with Venom physically but also with the emotional turmoil of being unmasked. His friends and family might be in danger, and he has to find a way to protect them while dealing with the public knowing who he is. Maybe he tries to convince the public that he's still on their side even though his identity is out.
One possible scenario is that Spider - Man, now as Venom, has to face new and different villains. His powers have changed, so the way he battles foes would be different too. He might have an advantage against some villains who were previously difficult to defeat, but at the same time, he could also attract the attention of more powerful enemies who see the Venom - powered Spider - Man as a greater threat.
In fanfiction, when Spider - Man reunites with Venom, they might have an epic battle at first. But then, they could realize they have a common enemy and team up. For example, a new super - villain could emerge in the city, threatening both of them and the innocent people. Their combined powers, Spider - Man's agility and Venom's brute strength, would make them a formidable force against the bad guy.
In fanfiction, if Spider - Man becomes a spider, it would be a total transformation. His identity as Peter Parker would be almost completely lost. He would have to adapt to a new body structure. His suit might not fit him anymore, and he would need to find a new way to protect himself. Also, his enemies might not recognize him, which could be both an advantage and a disadvantage in his battles.
In the fanfiction where MCU Spider - Man and Venom meet, Spider - Man might initially be terrified of Venom. After all, Venom is this big, hulking, and somewhat menacing figure. However, as the story progresses, they could start to understand each other. Venom could realize that Spider - Man isn't just some weakling, and Spider - Man could see that Venom has his own motives that might not be entirely evil. They might then form an uneasy alliance.
Well, he could bring his unique powers to the RWBY world. His web - slinging ability would be really cool in the RWBY setting. He might team up with the RWBY characters and help them fight against Grimm. Maybe he'd use his agility to outmaneuver the Grimm that the RWBY teams find difficult to handle.
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.
