Another concept could be that one of the NCIS agents has a family member who is in danger because of a supervillain's plot. The Avengers get involved to protect the agent's family, but the NCIS team doesn't trust them at first. Gibbs would be very protective and suspicious. As the story progresses, they all learn to work together. Ziva could show off her combat skills to Black Widow, and they could have a friendly sparring match while sharing their combat experiences.
The Avengers could enlist the help of the NCIS when they need to solve a mystery on Earth that doesn't require superpowers but rather good detective work. For instance, if there is a conspiracy within a government agency that is related to a potential threat to the Avengers. The NCIS agents would use their skills to dig into the files and interview suspects. In return, the Avengers could protect the NCIS agents when they are in danger during the investigation. There could be some great banter between the two groups, like DiNozzo trying to make jokes with Clint Barton about their marksmanship skills.
One great 'NCIS LA and NCIS Crossover Fanfiction' is 'The Joint Operation'. It combines the unique characters from both shows really well. 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 common theme is the cooperation between the two teams. Since they come from different but related agencies, the fanfictions often focus on how they learn to work together. For example, they might have to overcome differences in their investigative techniques.
One great 'ncis ncis los angeles crossover fanfiction' story is 'The Joint Mission'. It combines the characters from both shows in a really exciting way.

One idea could be that the NCIS team is investigating a series of strange murders that seem to have a supernatural element. They end up calling in the Winchesters from Supernatural for help. The two groups initially clash due to their different methods but eventually learn from each other and solve the case together.
One idea could be that some of the NCIS agents are sent on a mission to a world that has similarities to the Naruto universe. They could team up with Naruto and his friends to solve a mystery that involves both their worlds, like a powerful weapon that could disrupt both dimensions. The NCIS agents would be shocked by the ninja skills and chakra usage, while Naruto and his friends would be intrigued by the advanced technology of the NCIS.
One reason is the expansion of the universe. By crossing over, fanfiction writers can explore new relationships between characters. They can put characters in situations that test their limits and abilities. Moreover, the fans are already attached to the characters from both shows. So when they are combined, it's like a dream come true. It gives a chance to see how the LA - based agents would handle a case that's more in the realm of the original NCIS and vice versa.
A really interesting piece of fanfiction in this crossover genre is 'Cross - Agency Tensions'.
