One common theme is the transfer of skills. Naruto's ninja skills are often incorporated into the Nightwing persona. Another theme could be about Naruto adapting to the DC universe's culture and values. And sometimes, there's a theme of friendship, like Naruto making new friends in the DC world who are similar to his friends in the Naruto universe.
Yes, there are some interesting ones. You can check out fanfiction platforms like FanFiction.net or Archive of Our Own. Just search for 'Naruto is Nightwing' and you'll likely find a variety of stories with different takes on how Naruto could be like Nightwing in the DC universe. Some might focus on Naruto having similar acrobatic skills, while others could explore his character in a more detective - like role similar to Nightwing.
When writing a Naruto and Nightwing fanfiction, think about the settings. You could set it in Konoha, the Naruto universe, and have Nightwing be the outsider adjusting to the new environment. Or set it in Gotham and have Naruto be the fish - out - of - water. Consider their personalities when creating dialogue. Naruto is often enthusiastic and impulsive, while Nightwing is calm and strategic. Use this contrast to create interesting conversations and interactions. Also, don't forget to add some action scenes. For Naruto, it could be a big battle with a powerful ninja. For Nightwing, a fight against a Gotham villain. This will keep the readers engaged.
One great Naruto and Nightwing fanfiction could be a crossover where Naruto's world of ninjas meets Gotham City. Maybe Naruto is on a mission and accidentally ends up in Gotham. He teams up with Nightwing to fight some common enemies like a new villain who has both ninja - like skills and is causing chaos in the city. Another idea could be a story where Nightwing somehow gets transported to the Naruto universe and has to learn to use chakra and ninjutsu. There are also stories that focus on a more emotional aspect, like Nightwing befriending Naruto and helping him deal with his inner demons, similar to how he helps the young heroes in Gotham.
He might try to reason with kaldur. If Nightwing can make kaldur see that what he's doing is wrong or that there are better ways to achieve his goals, kaldur could let him go. Nightwing is known for his charisma and intelligence in such situations.
He might try to engage Slade in conversation. Nightwing is smart and could be looking for a way to psychologically get an edge over Slade. He could be probing for Slade's motives, hoping to find a way to turn the situation around. He might also be stalling for time, waiting for the right moment to make his move.
Batman is the most likely. He has a strong bond with Nightwing and would do anything to save him. His skills in combat and detective work would be crucial in finding and freeing Nightwing.
Nightwing would initially be defiant. He's a highly trained fighter and detective in his own right. So, he won't cower in front of the Joker. He'll probably try to size up the situation, looking for any weaknesses in his captivity and the Joker's plan.
Batman could be a main character. Since Nightwing was trained by Batman, in a baby Nightwing fanfiction, Batman could be the one taking care of him, teaching him basic skills, and protecting him from the threats of Gotham.
Captain America could be a strong ally for Nightwing. Captain America is a great leader and has a strong sense of justice. Nightwing, coming from Gotham, also has a deep - rooted sense of right and wrong. They could lead the Avengers together in a battle, with Captain America providing the strategic leadership and Nightwing using his agility and combat skills to execute the plans on the ground.
