One possible scenario in an 'OC Becomes Venom' fanfiction could be that the OC is an ordinary person who stumbles upon the Venom symbiote. Maybe they're in a lab accident or find it in an alley. Once bonded, they start to struggle with the new powers and the alien's aggressive nature. At first, they might accidentally use the powers in ways that cause chaos, like breaking things when they try to move quickly. But as time goes on, they learn to control it and use it for good, like protecting their neighborhood from small - time criminals.
Well, the OC could initially be terrified of the changes. They might wake up in the middle of the night with the symbiote taking over and not know what to do. Their friends and family could be scared of them too. But then, they start to discover the cool aspects of being Venom, like being able to climb walls and sense danger. They could end up using these powers to save their city from a new super - villain who is causing havoc.
In a fanfiction where Peter Parker becomes Venom, it could be due to a scientific experiment gone wrong. Maybe Oscorp was working on a new symbiote project, and Peter, being the curious and heroic type, gets involved accidentally. The transformation would change his personality, making him more aggressive at first as he struggles to control the new power. He might initially see the symbiote as a curse but later learn to use it for good, in a different way than he does with his Spider - powers.
In fanfiction, if Spiderman becomes Venom, it could lead to some really interesting relationships. His friends and family might be scared of him at first. But he could also form new alliances with characters who were previously his enemies because they see his new power as an opportunity. And his suit would be a lot more menacing, with the Venom look.
One common theme is the struggle for power. Often, the OC has to deal with the overwhelming power of Venom and either learn to control it or be controlled by it. For example, in some fanfics, the OC tries to use Venom's power for good but has to constantly battle the darker impulses that come with it.
One possible scenario could be that Finn, after being turned into a vampire, struggles with his new identity. He might have to deal with the urge to drink blood while still holding onto his old values. For example, he could try to find alternative ways to satisfy his thirst that don't involve harming humans, like drinking animal blood.
One idea could be an OC who is a scientist trying to find a cure for the Venom symbiote's negative effects. This OC could have a complex relationship with Venom, initially seeing it as a subject to study but later developing a bond. Another idea is an OC that is a street - level hero who teams up with Venom to fight crime in a seedy part of the city. They might have different methods but find common ground in protecting the innocent.
One possible scenario in this fanfiction could be that Finn's transformation into a vampire brings out a whole new side of his personality. He might struggle with his newfound thirst for blood while still trying to uphold his heroic values. Maybe he teams up with Marceline, who is already a vampire, and she teaches him how to control his urges.
The story could start with Spiderman getting infected by the symbiote in an unexpected way. Then he'd start to notice changes in his behavior and powers. His costume might change gradually to the Venom look.
Well, perhaps in the fanfiction, Spider - Man is tricked into becoming Venom. A villain could manipulate the situation so that the Venom symbiote attaches to Spider - Man. As Venom, he starts to see the world from a different perspective. His relationships with his friends and family become strained as they don't recognize the changed Spider - Man. He has to find a way to break free from the symbiote's control while still using its power for good.
Well, in an adventure story, venom could be a really dangerous element. For example, there might be a venomous snake in a jungle adventure. The hero has to be very careful not to get bitten by it as the venom could be deadly. He might have to use his knowledge of the local plants to find an antidote in case of a bite.
