Fanfiction.net is also a good place to look. There are likely to be some Red x Young Justice fanfics there. Browse through the Young Justice category and keep an eye out for stories that feature Red x. Sometimes, the titles or summaries will give you a clear indication if it's about Red x and Young Justice.
Definitely. I've come across some interesting ones. In some fanfics, Red x has a sort of love - hate relationship with the Young Justice members. There are those that show his redemption arc as he starts to see the value in what the team stands for. It's really fascinating to see how different authors interpret his character and his place in the Young Justice world.
One possible idea for a 'Young Justice Red X Clone' fanfiction could be that the clone has to struggle with identity issues. It's constantly compared to the original Red X and has to find its own place in the world. Maybe it starts out as a weapon created by an enemy but then begins to develop its own sense of self.
One interesting Young Justice Red X fanfic could be 'Red X's Redemption'. It might explore his character in more depth, his motives, and how he interacts with the other Young Justice members. It could show his journey from being a bit of an enigma to a more understood and perhaps even heroic figure within the story's universe.
Perhaps the clone has memories of the original Red X that it doesn't understand. These memories could lead it on a journey of self - discovery, trying to figure out who it really is and what its connection to the original is. It could be a very character - driven story within the Young Justice universe.
Robin is a great character to pair with Red X. Their dynamic can be really interesting as they are both quite intelligent and skilled. They could be either rivals constantly trying to outwit each other or begrudging allies who realize they need each other's skills.
One interesting Red X fanfiction could be about his origin. Maybe it delves into how he got his powers and his connection to the Young Justice team in a way that wasn't fully explored in the original series. For example, a story where he was originally a test subject for some secret government project related to the meta - genes.
One possible fanfic could be about a young boy who idolizes Batman but then discovers the allure of the Red X character. He might start to create his own version of a hero who combines the mystery of Red X with the justice - seeking of Batman. For example, in his daydreams, he imagines himself using Red X's gadgets to outwit villains in Gotham City, while still adhering to Batman's moral code.
I'm not sure about a specific fanfic title, but in general, a good Superboy x Vampire fanfic might explore how Superboy's powers interact with vampire abilities. Maybe in some fics, the vampire's powers could be enhanced by Superboy's Kryptonian energy. You could try searching on fanfic platforms like Archive of Our Own, using the tags 'Young Justice', 'Superboy', and 'Vampire' to find some interesting reads.
In a fanfiction, Red X could be from an alternate dimension where he has a different backstory. When he meets Young Justice, it causes a rift in the multiverse. The team has to figure out how to send him back while also dealing with the chaos his presence has brought. Maybe his powers interact in strange ways with the powers of the Young Justice members, creating both challenges and opportunities for them.
