What could happen in a 'fan of fairy tail possesses Lucy's body' fanfiction?

Mirajane would be an interesting character to interact with. She has a very mysterious side to her, with her Satan Soul ability. The fan in Lucy's body could try to uncover more about her past and the secrets of her powers. And Mirajane is also very kind and motherly towards the guild members, so the interaction could be very warm and friendly.

Midnight might use his illusions to make Lucy think she's lost her Celestial Keys. This would be a huge psychological blow to her. But then Lucy could remember the bond she has with her spirits and break through the illusions. It would be a battle of wills as much as magic.

One possibility is that the guild would experience a significant emotional impact. Lucy is a central figure, and her celestial spirit magic has been crucial in many battles. Juvia, with her water magic, is also a strong member. Their departure might lead to a decrease in the guild's overall power. Some members might feel betrayed, while others could be motivated to find out why they left and try to bring them back.

In some fanfictions, when Lucy is alone, she might have a chance to further develop her celestial magic skills. She could be exploring new spells or ways to communicate more effectively with her spirits. For example, she might discover a hidden power within one of her keys that she hadn't noticed before because she was always with the team.

Well, if Natsu asks Lucy out in fanfiction, it could change the whole dynamic of the Fairy Tail group. Their friends would probably be super supportive, especially Happy. They could start exploring new places not just for quests but also for romantic getaways. And Lucy might write a new story about their relationship in her diary.

In fanfiction, during their alone time, Natsu and Lucy might simply have a deep conversation. They could talk about their dreams, like Natsu sharing his desire to find Igneel more in - depth, and Lucy might open up about her hopes for her Celestial Spirit magic to grow stronger.

Another possibility is that they get into a bit of a light - hearted argument over something silly like who has the better taste in food. But in the end, they would just laugh it off and realize how much they enjoy each other's company during this alone time.

In the fanfiction, the person waking up as Lucy would have to face the challenges that Lucy herself has. This includes dealing with her past, like her relationship with her father. She would also have to manage her relationships with other guild members, such as Natsu and Erza. And of course, she'd need to keep up with her training to become stronger in magic. Maybe she'd even try to create new spells or improve on Lucy's existing ones.

Perhaps the new keys are part of a prophecy. In the Fairy Tail universe, prophecies are common. So, Lucy finding these keys could be the start of fulfilling a great prophecy. It could involve saving the world from a dark magic that only she, with her new celestial spirits summoned by the keys, can stop. This would not only test her strength but also her loyalty to Fairy Tail and her friends.

In a fanfiction where Lucy and Erza kiss, it could be a moment of deep friendship evolving into something more. Maybe they've just had a really intense battle together and the adrenaline rush makes them realize their feelings for each other in a new way. It could also be a situation where they are comforting each other after a difficult event in the Fairy Tail guild, like the loss of a fellow member. Their kiss could be a symbol of their unbreakable bond.
