In a 'nightwing meets spiderman' fanfiction, they could team up to fight a common villain. Maybe a powerful criminal who has the ability to move between Gotham and New York unnoticed. They would combine their unique skills, Nightwing's acrobatics and combat skills with Spiderman's super strength and web - slinging.
One idea could be that Nightwing is transported to the Avengers' universe through some sort of interdimensional rift. He then has to team up with the Avengers to fight a common enemy, like Thanos who has somehow acquired some of Batman's tech. Nightwing's acrobatic skills and detective abilities would be a great addition to the Avengers' power set.
I think it would vary depending on the writer's perspective. If the writer wants to emphasize the importance of experience and training, then Nightwing might be more dominant. He has years of experience fighting crime in Gotham. On the other hand, if the focus is on raw power and the ability to adapt quickly, Spiderman could be the more dominant character. His powers give him a wide range of abilities that he can use in different situations.
Well, perhaps in this fanfiction, there's a multiverse rift that pulls Nightwing into the Avengers' world. The Avengers initially mistake him for an enemy, but after some misunderstandings are cleared up, they realize his skills. Together, they face a new threat created by a combination of Hydra and some of Nightwing's rogues gallery who have also crossed over. Nightwing could teach the Avengers some stealth tactics while they show him how to handle more powerful cosmic threats.
One possible plot could be that Nightwing is somehow involved in a case that crosses over into the NCIS jurisdiction. Maybe there's a criminal organization dealing with both high - tech gadgets (Nightwing's area of expertise) and military - related crimes (NCIS). The NCIS team initially suspects Nightwing but then realizes he's an ally and they team up to take down the bad guys.
A Nightwing crossover with the Flash would be exciting. Picture Nightwing trying to keep up with the Flash's speed during a battle against a speed - stealing villain. Or a crossover with Green Arrow, where they both take on a group of criminals in Star City and Blüdhaven, and have to combine their different fighting styles.
First, think about the role of the lemon. It could be a magical lemon that gives Spiderman a new power, like the ability to shoot acidic webs. Then, create a plot around this new element. For example, a villain wants to steal the lemon to gain the power for himself. Next, consider how Spiderman's character will interact with this lemon - related concept. He might be skeptical at first but then realizes its potential. Finally, write the story with action, dialogue, and a good flow.
One interesting aspect could be how Spider - Man's agility and street - level skills blend with the Avengers' more high - powered abilities. For example, his web - slinging could provide a unique form of transportation or capture for the team during a big battle against a powerful villain like Thanos. He could also use his spider - sense to detect threats that the other Avengers might miss.
At the start, the NCIS agents would likely view Nightwing as an unknown vigilante. But as they get to know him, they'd see his value. For example, Tony from NCIS might crack some jokes at Nightwing's expense at first, but then be impressed by his detective skills. Abby would be fascinated by Nightwing's gadgets. And as for Nightwing, he'd adapt to the NCIS agents' more official and structured way of doing things. He might also share some of his knowledge about the criminal underworld in Gotham with them, which could be very useful in their investigation.
Red Hood is another good option. The two have a complex relationship, and a crossover could explore their past grudges and how they might overcome them to fight a common enemy. It could also show how their different approaches to justice collide and then reconcile.
