Who would be the most interesting character to interact with in a 'fan of fairy tail possesses Lucy's body' fanfiction?

Well, one possibility is that the fan might use Lucy's body to experience the magical world of Fairy Tail in a more immersive way. They could interact with the other characters, like Natsu and Erza, in a completely different dynamic since they have the body of a main character.

Definitely Gray. Their personalities are quite different. Gray is cool - headed and uses ice magic, while Wolverine is more of a rough - and - tumble fighter. The contrast in their powers and attitudes would lead to some great banter and interesting team - up moments.

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.

Natsu would be a likely candidate. He's always up for a challenge and not afraid to take on powerful opponents. He'd probably be the first to rush towards Godzilla, either to fight it or try to befriend it in his own Natsu - like way.

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.

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.

Definitely Naruto and Natsu. Their personalities are quite similar in some ways, both being hot - headed and determined. In a fanfiction, their interactions could be really fun to read. They might start off as rivals, constantly trying to outdo each other in terms of strength and courage, but then gradually become friends and learn from each other's skills.

Death the Kid would be an extremely interesting character for Lucy to interact with. His obsession with symmetry and his powerful abilities as a meister could lead to some really unique scenarios. Lucy might be both fascinated and a bit put off by his quirks at first. But as they get to know each other, they could learn a great deal from one another. For example, Death the Kid could help Lucy understand the importance of precision in combat, which could enhance her use of celestial spirit magic, while Lucy could introduce him to the concept of celestial spirits and their different powers.

Yugi and Natsu would be an interesting pairing. Yugi is calm and strategic, while Natsu is impulsive and powerful. They could balance each other out. Yugi could use his intelligence to plan their adventures, while Natsu could use his fire - based magic to fight off enemies. Another interesting pair could be Erza and Kaiba. Erza is a strong and disciplined warrior, and Kaiba is a proud and powerful Duelist. They could have some epic battles of wills and skills.

Erza and Captain America would be an amazing combination. Erza is a strong and disciplined warrior in Fairy Tail, and Captain America is the symbol of justice and leadership in the Avengers. Erza's various armors and combat skills combined with Captain America's shield and strategic thinking would make them a formidable team. They could lead the combined forces of Fairy Tail and the Avengers in battles against powerful foes, and also inspire the other characters with their unwavering determination.
