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.
A 'Justice League meets Nightwing' fanfiction could involve Nightwing being called in as an expert on a particular type of threat. He could then train some of the younger Justice League members in his unique combat style. There might also be a plot where Nightwing has to make a difficult decision that goes against the initial plans of the Justice League, causing some tension at first but ultimately leading to a better solution for everyone.
A potential storyline could be Nightwing joining the Justice League on a trial basis. He has to prove himself to the more established members. This could involve a series of missions where he showcases his skills in detective work, combat, and teamwork. Another storyline could be Nightwing being wrongly accused of something by the Justice League, and he has to clear his name while also dealing with the threat of a common enemy.
In fanfiction, when Nightwing meets the Justice League, he might show off his acrobatic skills. His unique fighting style could impress the more powerful members like Superman. Maybe he'd also offer his detective skills to help solve a mystery the League is facing.
One possibility is that Nightwing brings his unique set of skills and street - level experience to the Justice League. He might initially be seen as an outsider by some members, but his charm and combat abilities would quickly earn their respect. For example, he could offer new strategies for dealing with villains who operate in the shadows of cities, which the more powerful but sometimes less street - savvy League members might not have considered before.
Nightwing often plays a key role in Justice League War fanfiction. He can be a mediator between different factions within the League. His experience working in the shadows and on the streets gives him an edge in understanding the more complex situations that arise during the war.
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.
Obviously, Nightwing himself is a key character. Then there would be Superman, who might be curious about Nightwing's abilities. Batman could also be involved in some way, as Nightwing has a connection to him. And Wonder Woman, she might interact with Nightwing, perhaps sparring or discussing battle strategies.
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.
