A third storyline could be a mystery - centered one. Seth and Joey discover a strange and ancient Duel Monsters card that seems to have some sort of hidden power. They decide to team up to figure out what the card is all about. As they research, they encounter various obstacles and enemies who also want the card for their own malicious purposes.
One possible storyline could be that Seth and Joey are rivals at first. They constantly compete in Duel Monsters tournaments. However, as the story progresses, they realize they have more in common than they thought and end up becoming friends. Maybe they team up to take on a greater threat in the Yu - Gi - Oh world, like a powerful and evil Duelist who is causing chaos.
In a fanfiction, they could also develop emotionally. Suppose they both experience a great loss in a duel. Instead of sulking separately, they support each other. This shared experience could deepen their bond and lead to more complex character arcs. For instance, they might start to see each other as family, which is a huge step in their character development in the Yu - Gi - Oh fanfiction world.
One popular fanfiction could be 'Set and Joey's Dueling Bond'. It might explore their relationship during a high - stakes duel where they learn to respect each other's skills more deeply. Another could be 'Set's Hidden Admiration for Joey', which delves into Set's feelings that he might be hiding from others about Joey. There could also be 'The Team - Up of Set and Joey', where they have to work together against a common enemy in the Yu - Gi - Oh universe.
One possible storyline could be the male OC coming to Duel Academy as a transfer student with a mysterious past. He has a special deck that no one has seen before and quickly rises through the ranks, making both friends and enemies along the way.
I'm not entirely sure if there is a lot of 'Yu - Gi - Oh! Joey Pregnant' fanfiction. It could be a very niche or even a rare find. Fanfiction often explores a wide range of ideas, but this one seems rather unusual for the Yu - Gi - Oh! franchise. You might have to dig deep into the archives of fan - created stories to find it, if it exists at all.
A plot might involve some sort of magical or otherworldly event that causes Joey to become pregnant. Maybe a powerful duel monster's spell backfires on him. His pregnancy could then be a central point for exploring how the Yu - Gi - Oh! universe deals with such an unexpected situation. It could also lead to new alliances and rivalries as different characters have different views on his condition. This could all unfold while still maintaining the essence of the Yu - Gi - Oh! world with its duels and friendships.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of Yu - Gi - Oh fanfictions, and you can easily search for Set x Joey ones using the search function. Another option is FanFiction.net. There are many Yu - Gi - Oh fans who post their works there, and you're likely to find some interesting stories about Set and Joey.
Well, Aster could be part of a time - traveling adventure in a Yu - Gi - Oh GX fanfiction. Maybe he gets sent back in time to the early days of Duel Monsters and has to adapt to the different rules and card availability. Or perhaps he teams up with some of the classic Yu - Gi - Oh characters to face a common enemy that threatens both their timelines.
Joey could be involved as an imaginary friend. The babysitter tells the kids all about Joey from Yu - Gi - Oh and they start to pretend that Joey is there with them, helping them solve problems or play games.
Well, in Yu - Gi - Oh GX fanfiction involving Baby Aster, often there are storylines centered around his family background. Since we don't know much about his family in the original series, fanfiction writers might create stories about his parents or his upbringing. Also, his growth as a duelist could be explored. He starts as a very talented duelist, but in fanfiction, he could face challenges that force him to grow in different ways, such as learning new strategies or dealing with losses in unique ways.
In a fanfiction, they could participate in a grand tournament. But this tournament has a twist. It's not just about winning duels but also about solving puzzles and riddles related to the history of dueling. Astral's vast knowledge and Yuma's intuition would work together. They would face opponents who are not only strong duelists but also cunning strategists. Along the way, they might also discover a new form of dueling that could change the future of dueling in their world.
