Naruto would probably be very friendly and curious about Ada Wong. He'd likely approach her with his usual enthusiasm and ask a million questions. Ada, being more reserved, might be a bit taken aback at first but would soon realize Naruto's good intentions.
A Naruto and Ada Wong fanfiction could involve time - travel. Maybe Ada Wong somehow gets transported to the Naruto universe in the past. Naruto, being the curious and friendly ninja he is, decides to help her find a way back home. Along the way, Ada teaches Naruto some of her advanced combat techniques, and Naruto shows her the power of chakra and ninjutsu.
In a Naruto x Ada Wong fanfiction, Ada Wong might be on a hunt for a powerful and ancient artifact that has been lost in the Naruto world. Naruto gets involved when he stumbles upon her during her search. At first, they are at odds, but as they learn more about the artifact and the danger it poses if it falls into the wrong hands, they start to work together. Ada Wong's experience with dealing with dangerous and powerful items combines with Naruto's ability to adapt and his unwavering spirit to create an exciting adventure.
Naruto is very outgoing and impulsive. Ada Wong is more reserved and calculating. So, Naruto would probably be the one to initiate conversations and try to get to know Ada Wong better. Ada Wong, on the other hand, might be initially cautious but gradually come to respect Naruto's enthusiasm. Their different personalities could lead to some interesting situations. For example, Naruto might rush into a fight while Ada Wong would be thinking of a more strategic approach.
One idea could be that Ada Wong, with her stealth and espionage skills, is hired to steal a powerful ninja art from Naruto's village. Naruto, being the hero he is, tries to stop her but ends up respecting her abilities and they form an uneasy alliance. Another could be a time - travel plot where Ada Wong is sent to the Naruto universe and has to rely on Naruto to get back to her own world. And a third idea is that they are both on a mission to stop a common enemy that is threatening both their worlds.
It's possible that Ada and Claire are part of a fantasy world. Ada could be a shape - shifter or a magical being, and Claire could be a human who has stumbled into Ada's world. The licking of the neck could be a sign of recognition, like Ada is identifying Claire as someone special or as a potential threat in that world.
Ada and Helena are likely characters from a particular fictional universe, perhaps from a game or a book series that has a fan base creating fanfiction about them.
Naruto is very open, loud, and determined. Ada Wong is more reserved, mysterious, and calculating. Their personalities could clash as Naruto might find Ada's secrecy frustrating. However, they could also complement each other. Naruto's boldness could inspire Ada to be more direct at times, and Ada's calm and collected nature could help Naruto think before he acts.
Hunnigan could be a great addition. She could provide Leon with information and support from the outside, and her presence could add some tension as she might be suspicious of Ada's motives. Another good character is Wesker. His past connection to Ada could create more drama and conflict in the story. He could be a shadowy figure trying to manipulate the situation between Leon and Ada.
Well, in the context of NCIS fanfiction involving Tony and Ada, it could be that the writer is exploring a romantic angle between them. However, this might be a deviation from the normal character dynamics in the show. Fanfiction often takes creative liberties to create new and exciting storylines. For example, they might be paired up on a dangerous undercover mission that leads to a deeper connection.
