Obviously, Conner Kent is the main character. But often you'll also see other Young Justice team members like Robin, Superboy, and Miss Martian. Aqualad might also show up. Sometimes there are villains as well, like Lex Luthor who has a connection to Conner.
One great Young Justice Conner Kent fanfiction is 'Conner's New Path'. It delves into his struggle with his identity in a really interesting way. Another is 'Conner and the Team', which focuses on his relationships within the Young Justice team. There's also 'Conner Kent: The Hidden Powers' that explores some unique powers he might possess.
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.
One possible scenario in a Conner and Wendy fanfiction could be them teaming up on a mission. They might start off not getting along well, but as they face challenges together, they begin to understand and respect each other's abilities more. For example, Conner's super strength and Wendy's unique skills could complement each other in combat situations.
You can try fanfiction websites like Archive of Our Own (AO3). There are often a lot of works in different fandoms there. Just search for 'Young Justice Conner Kent x Vampire OC' and you'll get a list of relevant fanfictions. Another option could be FanFiction.net, though AO3 usually has a more diverse range of content and better tagging system for finding specific types of stories.
They could be on a quest to find a missing teammate. Conner's physical powers and Wendy's intelligence would be crucial. They might search through different dimensions or hidden locations. Along the way, they face various enemies and obstacles. Their relationship would grow as they rely on each other to survive and complete their mission.
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.
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.
A popular type of Conner and Megan fanfiction could be a romantic one. It could start with them being just friends and teammates, but then gradually realizing they have deeper feelings for each other. There could be cute moments like when Conner tries to be more romantic for Megan, or when Megan uses her powers in a creative way to surprise Conner.
