The relationships might become more relaxed. For example, characters who are usually a bit reserved like Levy might be more open and friendly with others. Gray and Natsu, who often bicker, could end up laughing together over some drunken joke. And Lucy might be more affectionate towards her friends, giving hugs more freely.
Drunk Lucy could also be very argumentative. She might start debates with the more serious guild members like Erza about the silliest things, like whether or not it's proper to eat cake with a fork or hands. This would lead to some comical exchanges as the other members watch in amusement.
His relationship with Lucy would be interesting. If reborn, Natsu might be more protective of Lucy from the start. He could also share his past life memories with her, which would deepen their bond even more. They might start going on adventures together even earlier in the story.
Lucy and Natsu's relationship could become more intense. In some fanfictions, their bond might develop into a deeper romantic connection, which would change how they interact. Gray might become more of a rival, feeling like Natsu is getting more attention in these fictional scenarios.
In terms of her relationship with Gray, there could be a new dynamic. If'si' reincarnated as Lucy, she might be more competitive with Gray, which could lead to some interesting interactions. Her relationship with the celestial spirits would also change. She could become more like a mentor to them, teaching them new things from her past life or experiences. Also, her relationships with other guild members would likely expand. She might form closer bonds with some of the more reserved members of Fairy Tail, bringing them out of their shells.
In this kind of fanfiction, the relationships within the guild could deepen in different ways. Since there's no Grand Magic Games, the members would have more time to interact on a daily basis. This could lead to new romances blooming. For instance, Erza might have more time to get to know Jellal on a personal level without the distractions of the games. Also, the younger members could form stronger bonds with the older, more experienced ones as they would be around each other more often.
The relationship between Happy and Fan would be an interesting one. Happy was always very close to Lucy, and with Fan replacing her, Happy might be a bit standoffish at first. But if Fan shows kindness towards Happy and an understanding of his relationship with Natsu, Happy could start to accept Fan. Also, the relationships within the whole guild would shift as members would need to adjust to Fan's presence instead of Lucy's, which could lead to new friendships and rivalries forming.
Well, Natsu's relationship with Gajeel could be really different. Gajeel might be more respectful towards Natsu as a girl, or he could be more competitive in a different way, like trying to prove that he's the better dragon slayer in a more gentlemanly manner. Natsu's relationship with the guild master, Makarov, would also change. Makarov might be more protective of Natsu as a girl, and Natsu might have to fight harder to be taken seriously in guild matters. In general, all of Natsu's relationships would be reshaped, with new levels of complexity and humor added to the story.
His relationship with Lucy might become more protective. Since he's now more vulnerable with one arm, Lucy might feel the need to be stronger to protect him as well, which could strengthen their bond in a different way.
The hot - headed Natsu from Fairy Tail and Alibaba from Magi might start off as rivals, competing to see who is the stronger fighter. But as they face challenges together, they could develop a mutual respect for each other's courage and determination. They might learn from each other's fighting styles too, with Natsu learning some strategic moves from Alibaba and Alibaba getting inspired by Natsu's never - give - up attitude.
One plot idea could be that the drunk members start telling wild and exaggerated stories about their adventures. Another could be that they accidentally get involved in a friendly competition while drunk that leads to some comical chaos. Maybe they even mistake a stranger for an old enemy due to their drunken state and hilarity ensues.
