What could be the plot of a 'yusei becomes dark signer fanfiction'?

Some common themes in Dark Signer Yusei fanfiction could be redemption. Since the Dark Signers are often seen as antagonists, fanfics might explore their journey towards redemption. Another theme could be power struggles. Yusei, being a powerful duelist, might face intense power battles against the Dark Signers in these stories. Also, friendship can be a theme as Yusei tries to understand the Dark Signers and maybe even form an unlikely bond with them.

Crow Hogan is often a popular character to include. He's Yusei's friend and his presence can add more depth to the story. Another one could be Jack Atlas. His rivalry with Yusei and his strong personality make him a great addition. Also, Akiza Izinski might be included as she has her own powers and a connection to Yusei.

Romantic relationships would also be affected. If Yusei had a love interest, she or he would be heartbroken and confused. They might try to reach out to Yusei and bring him back from the dark side. But Yusei, as a Dark Signer, might push them away, believing that his new path is one he has to walk alone. His relationships with his mentors or older figures in his life would also turn sour, as they would see him as having strayed from the right path.

A really interesting fanfiction I came across was about Yusei's encounters with other Dark Signers before fully becoming one himself. It showed how he was gradually influenced by the dark forces. In some fanfictions, the author might focus on Yusei's new deck as a Dark Signer. It could have cards with darker themes and more powerful but dangerous effects. These fanfictions can offer a different perspective on Yusei's character compared to the original series.

Maybe Percy gets betrayed by his friends in the fanfiction. This could lead him to become dark as he loses trust in those he once cared about. He might then start using his powers in more aggressive and self - serving ways.

One possible plot could be that Naruto somehow gets transported to Yusei's world. He has to adapt to the new technology and rules while still having his ninja skills. Maybe he teams up with Yusei to fight a common enemy that threatens both their worlds.

Perhaps a fanfiction where Akiza is transported to an alternate dimension as a Dark Signer. In this new world, she has to use her powers to survive and find a way back home. Along the way, she forms new relationships and has to face off against powerful enemies who are intrigued by her Dark Signer abilities.

Well, one possible plot could be that Emma, after being pushed to her limits by the constant threats in her world, decides to embrace the power of the Dark One. She might start off using it for what she believes is the greater good, like protecting her loved ones from a new, more powerful enemy. But as she delves deeper into the dark magic, she starts to lose herself. Her relationships begin to fray as her friends and family see the changes in her. And she has to struggle with the internal battle between her old self and the new, dark self that is emerging.

One possible plot could be Carly's initial confusion and fear when she first becomes a Dark Signer. She might not understand what's happening to her and tries to resist the dark power at first.

One plot idea could be Carly's journey as a Dark Signer. Maybe she discovers a hidden power within her Dark Signer status and has to decide whether to use it for good or be consumed by the darkness. For example, she could use it to protect her friends from other more malevolent forces in the Yu - Gi - Oh universe.
