Yes, it can be. In many love fanfics, 'Nightwing' as a character can be the focus of the reader's interest or the object of affection. Writers often create various romantic scenarios involving Nightwing for readers who are fans of the character to enjoy.
One popular trope is the 'accidental meeting'. For example, the reader might accidentally bump into Nightwing during one of his patrols in the city. Another is the 'protective Nightwing' trope, where he saves the reader from danger and then a romantic connection begins to form.
A possible plot could be Nightwing getting betrayed by a close friend or ally. Maybe they were framed for something they didn't do, and this led to their heartbreak. For example, if a fellow hero believed false rumors about Nightwing and turned against him, it would shatter his trust and break his heart.
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 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.
One idea could be a story where Beastboy and Nightwing have to team up for a mission in a new, mysterious part of the city. They start off not getting along well due to their different personalities and fighting styles. Beastboy is more carefree and impulsive while Nightwing is methodical. But as the mission progresses, they learn to appreciate each other's strengths and form a strong bond by the end.
One common theme is discovery. The reader usually discovers their soulmate connection to Nightwing in an unexpected way, like through a shared dream or a special mark. Another theme is protection. Nightwing often tries to protect the reader from various threats because of their soulmate bond.
One great 'Batgirl and Nightwing' fanfic is 'City Lights'. It beautifully captures their relationship dynamics. The author does an amazing job of showing their teamwork and the underlying romantic tension between them. The action scenes are well - written and the dialogue feels very true to the characters.
Sure. A lot of fan creators are more interested in exploring the platonic side of their relationship. They might write about how Starfire's alien nature and Nightwing's leadership interact in the context of the team. For example, stories could be centered around how they train new Teen Titans members together, without any sexual undertones.
