In a Nightwing and NCIS crossover fanfiction, the plot might revolve around a stolen military weapon that has been modified by a Gotham - based villain. The NCIS team is called in to find the weapon, and they cross paths with Nightwing who is also after the same villain for other reasons. Nightwing has his own network in Gotham that can provide information about the villain's whereabouts, while NCIS has access to military databases and resources. Together, they follow the trail of the weapon, facing off against the villain's henchmen and uncovering a conspiracy that goes deeper than expected.
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.
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.
One plot idea could be a joint case where the NCIS team and the NCIS LA team have to work together to solve a crime that spans across different locations. Maybe a terrorist threat that has connections in both Washington D.C. (where NCIS is based) and Los Angeles.
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.

The plot usually involves a case that requires the expertise of both teams. It shows how the agents from NCIS and NCIS LA interact, like how Gibbs' no - nonsense approach clashes and also gels with Hetty's more mysterious style of leadership.
One possibility could be that Alex Rider is on an undercover mission that somehow intersects with an NCIS case. Maybe he's tracking down a group involved in international espionage and they turn out to be linked to a crime on U.S. soil that NCIS is also investigating. For example, a terrorist organization that is smuggling weapons and using the sea routes which is NCIS' area of expertise. Alex could bring his unique skills in combat and infiltration, while the NCIS team offers their forensic and military investigation knowledge.
Another plot point is the combination of powers and skills. Naruto has his powerful jutsus, and the NCIS agents have their forensic and investigative skills. When they team up, they can use these in unique ways. For instance, Naruto could use his shadow clone jutsu to search a large area quickly while the agents analyze the evidence the clones find. This synergy between two very different sets of abilities makes for an exciting story.
One possible plot could be that they team up to stop a powerful villain who has the ability to travel between their two cities. Maybe this villain is stealing tech from Gotham and super - powers from New York. They start off not trusting each other as they have different methods. Nightwing is more stealthy and trained in combat, while Spider - Man is more quippy and uses his webs in a very acrobatic way. But as they face challenges together, they learn to work as a team and combine their skills to take down the bad guy.
