A great fanfiction storyline could involve Superboy and Supergirl exploring their different upbringings. Superboy was created in a lab while Supergirl had a more traditional Kryptonian upbringing. Their differences could lead to some interesting character development and conflict as they learn to work together better.
One interesting storyline could be Superboy and Supergirl teaming up to face a new and powerful villain that the Justice League has overlooked. They might discover a hidden threat in Smallville that has ties to Krypton's past.
In some fanfictions, there could be a storyline where Superboy and Supergirl are sent on a mission to an alternate dimension. There, they find versions of themselves with different powers or personalities. This could lead to a lot of self - discovery as they interact with these alternate selves and try to find a way back home.
One interesting storyline could be them teaming up to face a powerful new villain that neither of them can defeat alone. They combine Robin's strategic mind and Supergirl's super strength to outwit the enemy.
A great fanfiction idea could be that Artemis and Superboy are stranded on an alien planet. Superboy has to deal with the unfamiliar environment while Artemis tries to find a way to signal for help. Along the way, they discover secrets about each other's pasts that they never knew before, which deepens their relationship.
Another common plot is where they deal with trust issues. Since Superboy is a clone and has his own insecurities, and Artemis has her secrets too. In some fanfictions, they have to work through these trust issues to become closer. Maybe there's a situation where Artemis's past actions are called into question, and Superboy has to decide whether to trust her or not, which makes for a very interesting and emotional read.
A third storyline could be set in an alternate universe where Nightwing and Supergirl are the leaders of a new generation of heroes. They have to deal with different rules and expectations, and face challenges that test their leadership skills. This could show how they grow as characters and how their relationship evolves in this new context.
Often, Superboy is really well - written. Writers can explore his struggle with his identity, being a clone. He has the power of Superman but also his own unique perspective, which makes for great character exploration in fanfiction.
One interesting Young Justice Superboy fanfiction could be about his struggle to fit in among the heroes. He has his own unique origin and powers, and a story could explore how he overcomes the feeling of being an outsider. Maybe he forms a special bond with another character like Miss Martian, and they help each other grow.
One popular storyline could be them teaming up against a powerful, previously unknown villain. They'd have to combine Superboy's strength and Robin's intellect to outwit the bad guy. Another might involve a personal conflict between them that they have to resolve while still facing external threats to the team. For example, a misunderstanding about leadership roles within the Young Justice group.
One interesting storyline could be Kara adjusting to life on Earth as a young girl. Maybe she's trying to hide her powers while also making friends at school. Another could be her learning about her Kryptonian heritage in a more personal way, like finding a hidden family heirloom that gives her new insights.
A great plotline could involve Superboy and Superman teaming up against a powerful new villain that neither could defeat alone. They would have to learn to work together and trust each other fully. This would show their different fighting styles and how they complement each other. For example, Superman's experience and calmness in battle could balance out Superboy's more impulsive nature.
A possible plot is that Superboy discovers a hidden vampire community in his city. The vampires are being hunted by a group of anti - vampire vigilantes. Superboy has to decide whether to side with the vampires or the vigilantes. If he sides with the vampires, he'll have to protect them from the vigilantes who think all vampires are bad. And if he sides with the vigilantes, he'll be going against his own sense of justice because he'll learn that some of the vampires are just trying to live peacefully. Another plot could be a vampire using their powers to manipulate Superboy's mind, but Superboy's strong will eventually breaks free, and then they form an unlikely alliance.
