In a 'Harry Potter is Gibbs' nephew' fanfiction, the plot could start with Harry's discovery of his relation to Gibbs. This could lead to him spending time in the Muggle world, learning about Gibbs' work and life. As he grows, he might find ways to incorporate his magic into solving problems in the Muggle world that Gibbs and his team face. There could be a conflict where the wizarding world authorities are not happy about Harry's close ties to the Muggle world. At the same time, Gibbs' team might have a hard time accepting the existence of magic at first. But through various adventures and challenges, they all learn to work together. Harry could use his magic to enhance the forensics work in NCIS, like using a spell to detect lies during interrogations. And Gibbs could teach Harry about loyalty and perseverance in a way that is different from what he has learned in the wizarding world.
Well, perhaps in this fanfiction, there's a family connection that was previously unknown. Gibbs' nephew could be a distant relative of Harry Potter through some convoluted wizarding family tree. They might meet during an international wizarding event. Harry, being the hero he is, would then help Gibbs' nephew understand his new - found wizarding heritage and protect him from any dark forces that might be interested in this newly discovered connection.

One possible plot could be that Gibbs helps Harry uncover some secrets about his parents that even the wizarding world doesn't know. Since Gibbs is a master at investigating, he could use his skills to dig into the past. Maybe there are some hidden connections between Harry's family and some muggle affairs. Harry, under Gibbs' guidance, could start to see the wizarding world from a different perspective, combining the practical thinking of Gibbs with his own magical abilities.
The relationship could start with a chance encounter. Maybe Gibbs' nephew gets lost in Diagon Alley while getting his school supplies, and Harry, being kind - hearted, helps him out.

One possible plot could be that Gibbs is called to Hogwarts to solve a mystery. Maybe a student has gone missing and Gibbs uses his investigative skills to find out what happened, all while trying to understand the magical world around him.
If they meet, there could be a lot of cultural clashes. Harry comes from a world where magic is normal and Gibbs is from a world where everything is based on scientific evidence and law enforcement. Harry might introduce Gibbs to things like butterbeer and thestrals. Gibbs could introduce Harry to things like NCIS procedures and how to handle a firearm. Their different perspectives could lead to some really interesting interactions and storylines.
One possibility could be that Harry is in a difficult situation, perhaps a mystery in a new world that he's not familiar with. He calls Gibbs because he has heard of Gibbs' skills in solving problems and investigations. Gibbs then uses his no - nonsense approach to start looking into the matter, guiding Harry through the steps of finding clues and making sense of the chaos around him.
They could go on an adventure to find a missing magical artifact that has fallen into the Muggle world. Gibbs' skills in tracking and Harry's knowledge of magic could be combined to track down the artifact before it causes any harm.
One possible plot could be that Snape discovers his relation to Harry early on. He then has to struggle with his feelings towards Harry. On one hand, he might feel a sense of family loyalty, but on the other, he still has his grudges and past issues. Harry, on his part, might initially be in disbelief but then start to see Snape in a new light. This could lead to them working together more closely to fight against Voldemort, with Snape being more open about his knowledge and skills to protect Harry.
Well, in this 'harry potter son of gibbs fanfiction', it could be that the author is exploring a whole new set of relationships. Harry, being the son of Gibbs, might have a different upbringing.

Also, it could lead to some interesting interactions with the existing Harry Potter characters like Hermione and Ron, as they might be intrigued by Harry's different family background.
