Another possible storyline is a time - travel story. Robin and Megan accidentally get sent back in time. They have to work together to find a way back to their own time while also trying not to disrupt the past too much. Along the way, they learn more about the origins of the Justice League and how their predecessors dealt with threats, which gives them new perspectives on their own roles as heroes.
One interesting storyline could be Robin exploring and mastering new powers that are unique to fanfiction interpretations. For example, he might develop the ability to communicate with animals in a way that's different from his usual skills. This could lead to him forming an animal - based team to help fight crime.
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.
Their relationship can be developed through shared challenges. For example, when they are stuck in a difficult situation like being trapped in an enemy's lair. They have to communicate, trust each other, and use their combined skills to escape. This would strengthen their bond.
There might be a fanfiction where Megan and Artemis get transported to an alternate dimension. In this new world, they have to rely solely on each other to find a way back home.

A third interesting storyline might involve a secret alliance between a member of the Justice League and a villain that the Young Justice team discovers. This discovery then sets off a chain of events where the Young Justice team has to decide whether to trust the rest of the Justice League and how to handle this new information without causing a complete breakdown in the superhero community.
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.
