I'm not sure if there is a specific 'Fairy Tail Lucy commits suicide' fanfiction. Fanfiction can cover a wide range of themes and scenarios, but this is a rather dark and uncharacteristic concept for the 'Fairy Tail' universe. It goes against the overall positive and adventurous spirit of the series. However, with the vast amount of fan - created content out there, it's possible that something like this might exist in a very small corner of the fanfiction world.
It would be extremely dark and out of place. Lucy is a character full of life and hope in the 'Fairy Tail' series. If there was a fanfiction with her committing suicide, it would likely involve some sort of extreme despair that was not shown in the original series. Maybe she would have lost all her friends in some tragic way, or she could have been pushed to the brink by some powerful and evil force that overcame her strong will. But again, this is all very much against the grain of the original 'Fairy Tail' concept.
In general, it's a very touchy subject. While fanfiction allows for a wide range of creativity, the topic of suicide is not something to be taken lightly. It may not be appropriate for all audiences, especially younger or more sensitive readers.
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.
Well, to find a Fairy Tail fanfiction involving Lucy and Froch, start with checking out dedicated Fairy Tail fan communities. These communities often have their own sections for fanfiction. Maybe post a request there asking if anyone knows of such a fic with Lucy and Froch. Another option is to use Google. Type in something like 'Lucy Froch Fairy Tail fanfiction' and look through the search results. Some of the top results might be what you're looking for.
In Fairy Tail fanfiction, Dark Lucy often represents a more complex and edgy version of the character. She might be portrayed as having a darker past or different powers. For example, she could have been influenced by some dark magic which changed her personality. This can add a new layer of depth to the Fairy Tail universe.
In fanfiction, Dark Lucy might be a part of a parallel universe story. In this universe, the events that shaped Lucy in the original Fairy Tail series happened differently. So she turned out to be 'Dark Lucy'. She could be a key figure in a war between light and dark forces in this alternate Fairy Tail world.
One great fanfiction could be where Lucy has to outwit Midnight in a battle of magic. Maybe she uses her Celestial Spirit powers in a new and creative way to overcome Midnight's illusions. It could be an action - packed story with lots of twists and turns.
Well, in fanfiction, Lucy might be crying because she lost a fight against a powerful enemy. Maybe she felt she let her friends down. For example, if she was unable to protect someone important in the story, it could lead to her breaking down in tears.
I really like 'Lucy's Dream Come True'. It's a fanfic where Lucy gets to achieve all her dreams in a really unique way. It shows her growth as a character and how she uses her magic in creative ways. Another good one is 'Lucy and the Celestial Spirits' which focuses on her relationship with the celestial spirits and how they help her in tough situations.
