If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.
There is a fanfiction called 'Lucy in the Alternate Realm'. This one is interesting because it sends Lucy to an alternate realm where she has to find her way back. Along the way, she meets different versions of her friends and has to use her wits and magic to survive. It's a great read for any 'Fairy Tail' and Lucy fan.
Yes, there are many non - inappropriate 'Fairy Tail Lucy' fanfictions. For example, some focus on her adventures and growth within the Fairy Tail guild. They might explore her relationships with other guild members in a friendly and positive way, like her friendship with Natsu and how they support each other during quests.
I think it depends on how it's handled. If the 'naked' aspect is just a shock - value title and the actual fanfiction is more about exploring Lucy's character growth, relationships, or her adventures in a tasteful way, it could be okay. But more often than not, it gives the wrong impression and might not be suitable for the overall Fairy Tail community which values things like friendship, courage, and magic more than such potentially inappropriate themes.
Well, 'Nerd Lucy in Fairy Tail' is another one. This fanfiction focuses on Lucy's journey as a nerd in the Fairy Tail world. She befriends other guild members who initially underestimate her but later come to rely on her vast knowledge of magic theory.
It could be a rival guild. They might see Lucy as a threat because of her powerful celestial spirit magic. By poisoning her, they hope to weaken Fairy Tail. For example, a guild that has always been envious of Fairy Tail's reputation and power.
Lucy could be developed by showing her struggle to control the more powerful star dresses. For example, she might initially be overwhelmed by the strength of a new star dress but gradually learn to master it through training and self - discovery. This would show her growth as a mage.
One great Lucy x Laxus fanfiction is 'A New Bond'. It focuses on how they start to rely on each other during a difficult mission. Their interactions are really well - written, with Lucy's kind heart slowly melting Laxus's tough exterior.
Perhaps it's a power related to the stars in a more direct way. Like she can draw energy from specific constellations and use it to enhance her attacks. For example, if she summons the power of Orion, she gets super strength and accuracy in her attacks.
