In such a fanfiction, there could be intense training sessions. The Young Justice members might learn new combat techniques from the Bat Family. For example, Robin could teach some of his acrobatic fighting moves to the others. There could also be a lot of team - building moments as they face a common enemy together, like a new super - villain in Gotham.
Dick Grayson (Robin/Nightwing) is extremely popular. He has a long history in the Bat Family and his acrobatic skills and leadership qualities make him a great character to write about. He also has a complex relationship with Batman, which can be explored in fanfiction.
A third idea is to have a time - travel plot where members of the Bat Family in Young Justice go back in time to a crucial moment in Batman's early days as a vigilante. They could witness events that shaped Batman into the hero he is and learn valuable lessons from it. Along the way, they might also accidentally change something in the past, creating a whole new set of challenges to fix in the present.
One idea could be that the Bat family is investigating a strange series of crimes in Gotham. Meanwhile, the Young Justice team stumbles upon a lead that takes them to Gotham as well. They initially clash due to different methods of operation. Batman tries to keep his family in line while also dealing with the young, headstrong heroes of Young Justice.
Some members of Young Justice could be embarrassed. For instance, if there are romantic fanfictions about them that are a bit too cheesy or if their weaknesses are overly emphasized in a not - so - flattering way. But others might be really intrigued and want to explore more of what the fans think about them.
Definitely Robin. He's a bridge between the two groups already. He has his own experience in Young Justice and is also an important part of the Bat Family. His character development could be really interesting as he tries to balance the two worlds.
Superboy from Young Justice might also be a likely candidate. He's often looking for his place and trying to prove himself. Meeting the Bat family could be a chance for him to show what he can do. He might be a bit brash at first, but once he realizes they are all on the same side, he could be quick to form an alliance. He could see Batman as a role model in a way, someone who is strong and has a sense of justice.
Some of them might be amused. They could find the different takes on their characters and stories quite entertaining. For example, Superman might chuckle at a fanfic that has him in a comical situation.
In this fanfiction, there could be epic battles. The Bat Family's stealth and detective skills might contrast with the Justice League's more overt superpowers. For example, Batman could outwit Superman in a strategic situation, showing that brains can sometimes be more powerful than brute strength. Also, the different relationships within the Bat Family could add depth. Robin might look up to the more experienced Justice League members, like Wonder Woman, seeking her mentorship. And there could be tension between the Bat Family's more grounded, Gotham - centered view and the Justice League's global perspective.
Well, perhaps in 'Justice League meets the Bat Family fanfiction', there would be a lot of character development. The members of the Justice League could learn from the Bat Family's more stealthy and detective - like approach. The Bat Family, on the other hand, could gain new perspectives on handling large - scale threats from the Justice League. There might also be some interesting dynamics between the different personalities, like the brooding Batman interacting with the more optimistic Flash.
