One interesting storyline could be Blue Beetle and Impulse teaming up to stop a new villain in the Young Justice universe. They could use their unique powers together, with Blue Beetle's high - tech suit and Impulse's super - speed. Maybe the villain is stealing technology that is related to Blue Beetle's suit, and Impulse helps him track down the bad guy quickly.
Adventure is also prevalent. Writers often send them on various missions together. For example, they could be on a quest to stop a new super - villain that's causing chaos in the city. These adventures allow the characters to show off their powers and personalities, and also give room for their relationship to develop further.
You can start by looking on fanfiction platforms like Archive of Our Own (AO3). It has a large collection of Young Justice - related fanfics. Just search for 'Blue Beetle x Impulse' in the Young Justice section, and you'll likely find many interesting stories.
Another idea is a time - travel fanfiction. Blue Beetle and Black Beetle could be sent back in time to a crucial moment in their predecessors' lives. They then have to make sure not to disrupt the timeline while also trying to gain some knowledge or power that can help them in their present - day battles. This would allow for exploration of their origins and how they've evolved over time.
In many Young Justice fanfictions, Blue Beetle is a symbol of hope and new - age heroism. His connection to the scarab, which is an otherworldly power source, gives him an edge. He can be used to bridge the gap between different groups of heroes, whether they are from Earth or have extraterrestrial origins. His character also has room for growth, as he discovers more about his powers and his place in the Young Justice world.
Maybe in a parallel universe fanfic. In this universe, Blue Beetle and Impulse are not superheroes in the traditional sense but normal teens. They meet at a school event and there's an instant attraction. The kiss could be a turning point in their relationship, but then they start to discover strange powers within themselves, which ties back to their superhero identities in another dimension.
The different universes they come from can add an extra layer of intrigue. Writers can play with the idea of how their powers and backgrounds interact in a romantic context. It allows for a lot of creativity in exploring their relationship, like how they might support each other during battles or in their personal lives.
A common storyline in Young Justice Green Beetle fanfiction could be his struggle to balance his personal identity with his heroic role. He might be from a different planet or culture, and the fanfiction could explore how he adapts to Earth's ways while still maintaining his own values. There could also be a story where he discovers a hidden power within himself during a crucial battle, which turns the tide in favor of the Young Justice team.
The idea of Blue Beetle's origin story is also a common theme. Writers might expand on it, or give it a different twist. For example, they might explore how he got the Scarab in more detail. His growth as a hero, both in terms of his powers and his character, is also often written about. He starts as a bit of an outsider in Young Justice, so his journey to fit in and become a respected member is a popular topic.
If they team up with Superboy, Blue Beetle could use his suit's advanced capabilities to analyze any threats while Impulse scouts ahead. Superboy could then provide the brute force when they encounter enemies. Blue Beetle might be a bit in awe of Superboy's strength at first, and Impulse would probably be impatient to get into the action. But they would all work together well, with Impulse's speed helping to keep the group coordinated.
One great storyline could be Impulse getting trained by Future Batman in advanced combat techniques. This would not only enhance Impulse's skills but also create an interesting dynamic between their different personalities.
