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.
It really depends on the circumstances. If the battle takes place in an area where Blue Beetle can make full use of his suit's technology, like in a high - tech cityscape, he might have the upper hand. His suit can provide various offensive and defensive capabilities.
There are Blue Beetle fanfictions that focus on his training. It could show how he hones his skills under different mentors or in unique training environments. One might be set in a virtual reality where he has to face his worst fears in order to become stronger. Another type of fanfiction could be a crossover. For instance, Blue Beetle teams up with the Teen Titans. In this story, he has to adjust to their team dynamics while also contributing his own unique abilities to fight a common enemy.
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.
