Naruto would likely be curious about the magic in the Fairy Tail world. He might see Lucy's celestial spirit magic as similar to his own summoning jutsu in a way. As for Lemon, if she has a friendly personality, Naruto would probably befriend her quickly. Fairy Tail characters, on the other hand, would be intrigued by Naruto's ninja abilities. They might ask him to show off some of his cool jutsus. Lucy could potentially teach Naruto about the different types of magic in Fairy Tail, while Lemon could offer her own unique perspective on things.
Naruto would probably be very enthusiastic and friendly towards Lucy right away. He might be curious about her celestial spirit keys and ask a lot of questions. Lucy, on the other hand, might be a bit more cautious at first but would be drawn to Naruto's positive energy.
Naruto's chakra - based powers and Lucy's celestial magic could interact in really cool ways. For instance, Naruto could use his Rasengan and infuse it with the magic power from Lucy's celestial spirits. Maybe a spirit like Aquarius could provide water - based magic that Naruto could use to make a more powerful water - style Rasengan.
Gray's protective side comes out when he's with Lucy. Since Lucy can be a bit naive at times, Gray feels the need to safeguard her. At the same time, Lucy's sassiness can keep Gray on his toes. She's not afraid to call him out when he's being too cold or distant, which in turn helps Gray to open up more.
The ninjas from Naruto are used to a more disciplined and hierarchical structure in their village. In contrast, the Fairy Tail members are more free - spirited. So, when Naruto meets the Fairy Tail guild, there could be some initial clashes. For example, Naruto might be confused by Natsu's impulsive and hot - headed nature. When it comes to Aquarius, Naruto could be respectful of her power as a spirit. He might try to learn from her about water - based abilities, while Aquarius could be intrigued by Naruto's chakra control.
For Zabuza from 'Naruto' in a 'Fairy Tail' fanfiction, he would interact with the characters in a very direct and often violent way. He would see the Fairy Tail mages as targets or obstacles. If he was hired to kill someone in the guild, he would not hesitate to use his sword skills against them. He might not understand the concept of friendship and loyalty that is so strong in the Fairy Tail guild and this could lead to some interesting clashes.
Naruto would probably be really excited to meet the Fairy Tail characters. He's a friendly and outgoing person, so he'd quickly try to make friends. With his Rinnegan, he might be able to sense the different levels of power among the wizards and be in awe of some of their magic. The Fairy Tail characters, on the other hand, would be curious about Naruto. Natsu might challenge him to a friendly fight at first, thinking he's just another tough guy. Lucy would probably be more cautious and ask a lot of questions about where he came from and what the Rinnegan is.
Lucy would probably be curious about Naruto. She might see his ninja abilities as a new form of magic. Naruto, on the other hand, might be a bit confused by her celestial spirit magic at first. But he would soon realize the power and importance of it. Their interactions could involve Lucy trying to get Naruto to open up about his world and Naruto being in awe of her magic collection.
In some fanfiction, Bickslow teases Lucy a lot, which is his way of showing he likes her presence. He might make fun of her in a light - hearted way about how she gets flustered around Natsu.
Bardock would probably be initially cautious around the Fairy Tail characters. Given his Saiyan nature, he is used to a more cut - throat and survival - based environment. But as he gets to know them, he would start to respect their loyalty and sense of family. For example, he might be impressed by how the guild members always have each other's backs, much like how Saiyans rely on their comrades in battle.
Natsu would be a very likely character. Since he and Lucy are close friends in the original story, if Lucy travels back in time, Natsu might be one of the first people she seeks out. They could have adventures together in the past, with Natsu being his usual impulsive self and Lucy having to keep him in check with her knowledge of the future.
