One great fanfiction could be 'Alya and Nino's Double Date Adventure'. It might have them going on a fun date with Marinette and Adrien, filled with comical misunderstandings and sweet moments.
Well, there are many great authors. One is 'LadybugLover123'. Their stories often feature Alya and Nino in really interesting situations. They do a great job of capturing the essence of their characters.
Alya as Volpina often brings a new dynamic to the fanfiction world of Miraculous Ladybug. She might have her own story arc that involves dealing with the power of the Volpina Miraculous in a different way than in the original show. Maybe she has to learn to control it better or use it to uncover secrets within the Miraculous universe.
One interesting Alya fanfiction could be where she discovers Ladybug's true identity on her own without any hints. In this fic, Alya's detective skills are really put to the test and she has to deal with the huge secret all by herself.
In my fanfiction, Nino gets the chance to become a temporary superhero. He is given a Miraculous - like device by an unknown entity. With this, he transforms into a hero with a unique look and powers. His main power is the ability to create force fields made of sound. He uses this power to protect the city from Hawk Moth's akumas and to support Ladybug and Chat Noir during tough battles. Nino also has to deal with the everyday problems of being a hero, like keeping his identity secret from his friends and family.
Well, it could be about Alya dealing with the challenges of being pregnant while still being involved in the superhero chaos. Maybe she has to keep it a secret from the villains who might use it against her. Or perhaps she discovers some new powers related to her pregnancy that help Ladybug and Chat Noir in their battles.
One interesting storyline could be Alya and Marinette teaming up to solve a mystery that is not directly related to the Akumas. For example, they might be trying to find out who is behind a series of strange disappearances in their neighborhood. They could use their unique skills - Marinette's creativity and Alya's investigative journalism skills - to piece together clues.
If the fanfiction takes a really wild turn, it could be that the father is a sentient Miraculous. I know it sounds strange, but in the world of fanfiction, anything is possible. Maybe the Miraculous has some sort of power that allowed it to impregnate Alya in a very unique and magical way, and the story then delves into how Alya and her friends deal with this extremely unusual situation.
A possible plot could be that Nino discovers a hidden underground society in Paris that has a connection to the Miraculous. He gets involved in their affairs and realizes that they have been secretly protecting the city from threats that even Ladybug and Chat Noir don't know about. He has to decide whether to share this information with his superhero friends or keep it to himself to protect the underground society.
One common plot is Alya using her Volpina powers to help Ladybug and Chat Noir without them knowing her true identity at first. It adds an element of mystery and secrecy to the story.
A really engaging fanfiction could be about Nino Turtle's origin story. It could explore how he first got his Miraculous, his initial training, and his feelings when he realized the great responsibility that came with being a superhero. This type of fanfiction gives a deeper understanding of the character.
