Redemption is also a popular theme. Sometimes, the OC has a troubled past and Venom becomes a means of redemption for them. Or, Venom itself might be seen as a character in need of redemption, and the OC helps in that process. For instance, if Venom has caused harm in the past, the OC might guide it towards a more positive path.
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.
Another theme is friendship. The OC and Venom form an unlikely friendship in many stories. They start off as strangers or even enemies but gradually come to trust and rely on each other. This is seen in stories where they face a common enemy and realize they are stronger together.
Power and its consequences are also a big theme. The OC might gain new powers through their connection with Venom, and they have to deal with the implications of that. For example, in some fanfictions, the OC has to learn to control their newfound strength so as not to harm the innocent. It's also about identity. How does the OC define themselves in a world filled with symbiotes and super - powered beings? This exploration of identity is quite common in these fanfictions.
One common theme is the discovery of the unknown. The oc girl often discovers Venom and has to come to terms with this strange and powerful being. Another theme is friendship. Despite their differences, they form a bond. Also, there can be a theme of protection, with Venom protecting the girl from various threats in the story.
The idea of Venom being an outcast is also common. Fanfictions may show how he tries to find his place in the world, whether it's among humans or in a world of his own kind. It adds depth to the character and makes for an engaging read.
One common theme could be the exploration of new family dynamics. Since it involves a 'pregnant' situation in the context of Venom, it might look at how the characters adapt to this new state.
One common theme is the struggle for coexistence. Since Venom is a symbiote and Eddie is a human, they have to figure out how to live together in harmony. Another theme is redemption.

Another theme is the struggle between good and evil. Some venom - vampires could be good, trying to protect the innocent, while others are evil and causing chaos. It's all about the moral battle within the characters.
One common theme is empowerment. Female characters with the Venom symbiote often discover newfound strength and use it to overcome obstacles. Another theme is identity. They have to figure out who they are now that they're bonded with Venom. And there's also the theme of acceptance, both of the symbiote and of themselves in their new state.
One popular theme is the relationship dynamic between Venom and the original character (OC). It could be a friendship where the OC helps Venom understand humanity better.

One common theme is the idea of protection. Spiderman will always strive to protect the pregnant character, whether it's someone he loves or an unexpected result of some strange event.

For example, they might need to find out if the pregnancy has any side effects on the powers of either of them.
