While all the characters have potential, Nightwing stands out. He has a rich backstory that could be delved into further. His skills in combat, detective work, and his ability to lead could all play important roles. In a story where he meets the Justice League, he could be the most interesting because he could be the underdog in a sense, having to prove himself among these super - powerful heroes, and that journey of self - discovery and acceptance within the group would be very engaging.
I think Nightwing would be the most interesting. He has this unique blend of skills and a different background compared to the more well - known Justice League members. His time as Robin and then his growth into Nightwing gives him a lot of depth to explore in the story.
Definitely the interaction between Nightwing and Robin (from Young Justice). Since Nightwing was once Robin himself, he could offer a lot of wisdom and guidance to the younger Robin. Also, the interaction between Nightwing and Artemis would be great. They both have a lot of combat skills and a bit of a sarcastic side, so their banter would be really fun to read. Another interesting one would be Nightwing and Superboy. Superboy might look up to Nightwing as a more experienced hero and Nightwing could help Superboy better understand his powers and his place in the hero world.
It could be Ben himself. His ability to transform into various aliens gives him a unique edge. He can adapt to different situations quickly, which would be fascinating to see when interacting with the Justice League.
I think Robin could be very interesting. He's young and full of energy, and in a meeting with the Justice League, he could be in awe of them at first but then prove himself. He might learn new skills from the League members and also show them that the Batfam has its own strengths. For example, his acrobatics and quick thinking could come in handy during a mission, and his interactions with characters like Aquaman or Green Lantern could be really fun to read about.
Batman would be really interesting. He's a master detective and strategist. He would be the one to study the Predator's behavior and try to find its weaknesses. His lack of superpowers but high intelligence would make for an interesting dynamic against the technologically advanced and physically powerful Predator.
I think Red Hood himself would be the most interesting. He has such a complex backstory, being a former Robin and now a vigilante with his own set of rules. His interactions with the Justice League members, who have their own moral codes, would be really fascinating to read about.
Batman could be the most interesting. He has a connection to both the Justice League and the Gotham villains. He knows how the villains operate better than anyone else in the Justice League. So, in this fanfiction, he would be in a unique position, trying to bridge the gap between the two groups and deal with his own complex relationship with the villains while being part of the super - team.
The interaction between Daredevil and Batman would be really interesting. They both are highly skilled detectives, but Batman has all his high - tech gadgets while Daredevil relies on his enhanced senses. They could compare notes on crime - fighting techniques.
Batman Beyond would be the most interesting. He's a new take on the Batman concept with his high - tech suit and different personality compared to the original Batman. He has to prove himself to the Justice League and show that he's just as capable, if not more so, in his own time.
Definitely Batman and Wonder Woman. Their different outlooks on justice would create some intense conversations. Batman is more about the gritty, street - level justice, while Wonder Woman has a more idealistic, Amazonian view.
Another interesting interaction would be between Oliver Queen (Green Arrow) and Batman. Both are non - superpowered heroes who rely on their wits, combat skills, and gadgets. They could share their knowledge of different fighting techniques and strategies. Oliver could learn from Batman's more high - tech approach, while Batman could gain some insights from Oliver's more improvised and outdoorsy combat style.
