I think Alfred from the regular Batfamily could be a really interesting character in this fanfiction. He's used to dealing with the Batfamily's heroics, but when faced with the reverse Batfamily, his loyalty and wisdom would be put to the test. He might try to find a way to reconcile the two groups or at least keep the regular Batfamily from being completely corrupted by the influence of the reverse Batfamily.
Well, in a 'batfamily meets reverse batfamily fanfiction', a lot of character development could occur. The members of the regular Batfamily would have to re - evaluate their own beliefs and methods when confronted with their opposites. Maybe they would start to question if there's a thin line between heroism and villainy. And the reverse Batfamily might also experience some changes, perhaps seeing a different path they could take from interacting with the 'good' Batfamily.
Alfred is also a great character in this context. He has to deal with the chaos that 'everyone meets the batfamily' would bring. He's the one who keeps the Batcave running and the Batfamily fed and taken care of. So seeing how he manages with a whole bunch of new faces around would be both humorous and interesting.
Batman himself is obviously a must - include. His leadership and skills are central to the Batfamily dynamic. Also, Robin, especially Damian Wayne as his complex relationship with Batman adds a lot of drama. Nightwing is popular too, with his acrobatic skills and his own journey away from being Robin. Batgirl, like Barbara Gordon, is often included for her intelligence and fighting abilities. And Alfred, the ever - loyal butler, who often provides support and wisdom to the family.
Batman and Superman would definitely have interesting interactions. Batman's more grounded, detective - like approach contrasted with Superman's super - powered idealism could lead to some great dialogue and moments of conflict and resolution.
Batman, for sure. He has such a complex relationship with the Justice League already. Meeting his family in this context would add another layer to his character. He's the bridge between the two groups.
The moment when the younger members of the batfamily look up to Bruce as a father figure is really heartwarming. In fanfic, it can be shown in small gestures like Bruce teaching them how to fix a car or cook. For Damian, it could be Bruce patiently guiding him through his emotions, which is a big step for Damian as he's not used to such emotional openness. It shows the family bond growing.
Well, in such a fanfiction, there could be a lot of interesting scenarios. Maybe Batman would have to deal with the different leadership styles of the Justice League while trying to keep his family in line. The Batfamily members could show off their unique skills to the League members, like Robin's acrobatics or Batgirl's hacking skills.
One possible storyline could be a joint mission against a powerful new villain. The Batfamily's detective skills combined with the Justice League's raw power would be a great combination. Another could be a sort of 'cultural exchange' where the League members try to understand the Batfamily's no - kill rule and the family tries to adapt to the League's more open - ended approach to heroism.
Well, it could be a wild ride of different characters interacting with the Batfamily. Maybe there will be some unexpected alliances or rivalries. For example, a normal citizen suddenly finding themselves in the middle of a Batfamily mission and having to either help or get out of the way. It could also show how the Batfamily deals with so many different personalities all at once.
Obviously, Batman and his family like Robin, Batgirl would be main characters from the Batfamily side. And from the Justice League, Superman, Wonder Woman, Flash etc. would be the main characters. They are the most well - known members of their respective groups.
