Another scenario could be a misunderstanding within the guild. Maybe a new member misinterprets Lucy's actions as a threat and attacks her. In the heat of the moment, before the situation is clarified, Lucy gets beat up. This could lead to a story arc about resolving misunderstandings and building trust within the guild.
There could also be a situation where Lucy is on a solo mission and is outnumbered by a group of bandits or rogue mages. Without the immediate backup of her Fairy Tail comrades, she might struggle and get beaten up. However, this could also be a moment for her character to grow, showing her resilience and determination to fight back and complete her mission.
In some fanfictions, Naruto might get beat up when facing a powerful new villain who has some unknown jutsu. This could be a villain created by the fanfic writer to test Naruto's limits.
Yes, there are likely fanfictions with such a plot. Fanfiction often explores different scenarios and relationships within the 'Fairy Tail' universe. However, not all of them are well - written or in line with the original spirit of the series.
Another scenario could be that in a battle against a new, extremely powerful foe, Lucy is caught in a crossfire between two massive magical attacks. Despite her friends' attempts to protect her, she gets fatally injured and dies. This would have a huge impact on the other characters in the Fairy Tail guild, leading to themes of grief, revenge, and moving on.
Another scenario might be a situation where Natsu accidentally eats some magic - enhancing food that makes his emotions go wild. Lucy has to figure out how to calm him down and in the process, they realize deeper feelings for each other. For example, Natsu might start uncontrollably shooting fire everywhere, and Lucy uses her whip to lead him to a safe place where she can try to reverse the effect.
In a battle against a group of powerful enemies, Natsu overexerts himself and is on the verge of being defeated. Lucy steps in. She first summons all of her available Celestial Spirits to create a powerful defensive formation around Natsu. Then, she combines her own magical attacks with those of her spirits to drive the enemies away. After that, she uses her healing magic (if she has developed such in the fanfiction) to nurse Natsu back to health.
Lucy could also cry when she faces betrayal. In fanfiction, there might be a new character who befriends her and then turns out to have ulterior motives. This sense of being deceived and used would be a big blow to her, and she would likely break down in tears. And sometimes, it's just the overall atmosphere of the story. If the fanfiction is set in a really dark and hopeless time in the Fairy Tail world, with the guild in danger and no clear way out, Lucy might cry out of fear and worry for her friends and the future of the guild.
Lucy getting beat up can also be a turning point for her character development. It might make her realize she needs to train harder or develop new magic skills. This could lead to her going on a training journey, which would be an interesting sub - plot in the fanfiction.
One interesting scenario could be when the baby's first magic manifestation occurs. It might happen during a guild party and startle everyone. Another scenario is that the baby gets lost in the guild's large building, and all the members, including Natsu and Lucy, go on a frantic search. A third scenario could be the baby developing a strange bond with an unexpected celestial spirit.
One popular scenario could be after a major battle where they both realize their deep feelings for each other. Natsu, being the impulsive and passionate character he is, might just grab Lucy and plant a kiss on her. Another could be in a moment of great celebration in the guild. With everyone around them having a great time, Natsu and Lucy get caught up in the moment and share a kiss. And sometimes, it might be in a more private, tender moment. Maybe Lucy is feeling down, and Natsu tries to comfort her in a more intimate way, leading to a kiss.
Maybe Lucy finds a long - lost spell book that belonged to a powerful Celestial Mage in the past. The spells in this book are the key to saving everyone. She spends time deciphering the ancient spells and finally manages to use one that can nullify the threat facing Fairy Tail. It could be a spell that can erase the existence of a powerful dark magic or something like that.
