An 'evil' Valt Aoi fanfic could explore his relationships in a different light. His friends might be shocked and have to deal with this new side of him. They would likely try to bring him back to his normal self. For example, Shu could try to reach out to him, but Valt, in his evil state, might reject him and see Shu as an enemy.
Well, one possibility is that Valt is influenced by an ancient and evil Beyblade spirit. This spirit convinces Valt that the only way to become the ultimate Beyblader is to embrace the dark side. So, he starts to change his behavior. He becomes more secretive and starts to isolate himself from his friends.
One idea could be a story where Valt and Shu are training together for an upcoming big tournament. They face various challenges during their training, like dealing with new and powerful opponents' techniques. As they train side by side, they start to understand each other's strengths and weaknesses better, and their friendship deepens into something more, with a lot of cute and competitive moments along the way.
In a fanfiction, Valt and Fem Shu could be in a situation where they have to rescue their Beyblades from an evil force. Valt would be all ready to charge in head - first, while Fem Shu would be thinking of a strategic plan. Their different personalities would create some interesting dynamics as they work together to save their beloved Beyblades and in the process, become closer friends.
In a fanfiction, Female Shu could be a new transfer student to Valt's school. Valt, being the friendly and enthusiastic beyblader he is, welcomes her. They quickly discover their shared love for beyblading. However, Female Shu has a secret technique she's been developing. Valt, intrigued, tries to learn from her and in the process, they develop a bond that goes beyond just beyblading. They support each other through personal and beyblade - related challenges.
One possible fanfiction could be about Valt and Chris Lemon teaming up for a special beyblade tournament. They might start off as rivals, with Valt's energetic and passionate style clashing with Chris Lemon's more calculated approach. As the story progresses, they learn from each other and combine their strengths to face a powerful common enemy in the tournament.
One great valt x shu fanfic could be about their journey in a new beyblade tournament together. They face tough opponents and their friendship deepens through the challenges.
