who is nightwing

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.

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.

It could be his arch - enemy. For instance, the Joker might play a cruel trick on Nightwing that makes him lose someone he cares about deeply, thus causing his heartbreak.

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.

Superboy could potentially be Nightwing's closest ally. Superboy has a lot of power but lacks the finesse that Nightwing has. Nightwing could help him control his strength better and in turn, Superboy could offer his brute force to support Nightwing in battles. Their relationship could grow as they face challenges together within the Young Justice team.

Deathstroke is a major villain. He is a highly skilled assassin and often clashes with Nightwing. His military - like tactics and combat skills make him a formidable foe for Nightwing.

Barbara Gordon also plays a significant role in many of the stories. She's Batgirl, and she has a complex relationship with Nightwing. And then there's Alfred, who provides support to Nightwing just like he does for Batman.

One possible fanfic could involve a battle against a powerful villain. Nightwing might get injured while trying to protect Gotham. Batman then has to step in not only to defeat the villain but also to take care of Nightwing. He could use his advanced medical knowledge and resources in the Batcave to nurse Nightwing back to health.

It's hard to say who the 'best' is as it depends on personal taste. However, some popular writers in the fanfiction community might be those who have a deep understanding of both characters' personalities and can write engaging action scenes. For example, some writers who have been around for a while and have a large following might be considered good at writing their stories.

Well, obviously Batman and Nightwing are the main characters. Batman, the dark and brooding protector of Gotham, with his vast array of gadgets and skills. And Nightwing, the acrobatic and more light - hearted hero who was once Robin.
