One great conner kent x oc fanfiction could be 'Conner's New Ally'. In this story, the OC might be a new meta - human in town with unique powers. Their relationship starts with a misunderstanding but gradually turns into a strong bond as they fight against common enemies together. It has a lot of action scenes and character - development for both Conner and the OC.
Don't forget about the plot. It can't just be about the relationship. Maybe there's a big threat to the city or the world that Conner and the OC have to face together. Include details about the setting, other characters' reactions to their relationship, and how the OC fits into the existing universe of Conner Kent. Also, use vivid descriptions to make the story come alive.
One common theme is the struggle between Conner's heroic nature and the Vampire OC's more primal instincts. It often creates a lot of internal and external conflict. Another theme could be the Vampire OC trying to fit into Conner's world of superheroes and justice, while hiding their true nature.
A popular one is 'The Drake - Kent Connection'. In this fanfiction, the author focuses on the unique dynamic between Tim and Conner. It starts with a mission they go on together and then gradually reveals their unspoken feelings for each other. The action scenes are well - written and the relationship development is quite natural.

Another common character could be Supergirl. She might be like a cool older sister figure to baby Conner Kent. She could help him understand his powers better, especially since they both share the Kryptonian origin. She might take him on little flying lessons or tell him stories about Krypton. And of course, there could be other alien characters from Krypton who show up to guide or protect baby Conner as well.
I really like 'Tim and Conner: Partners in Crime (Not Really)'. This fanfic focuses on their daily interactions. It shows how their different personalities, Tim's more cerebral approach and Conner's more impulsive nature, create both humorous and heartwarming moments. It's a great read if you want to see their relationship in a more light - hearted and day - to - day context.
Conner Kent's age in the comics can be a bit fluid. It depends on the creative direction of the writers. Generally, though, he's presented as being in his late teens to early twenties range.
