Maybe Mokuba would be a crucial character. As Seto's brother, he would be deeply concerned about his brother's transformation. He could be the one staying by Seto's side the most, trying to comfort him and also helping the others figure out how to reverse the spell. Another character could be Kaiba's business rival who might see this as an opportunity to take over KaibaCorp, adding some conflict to the story.
I think Tea could also be an important character. She might be the one taking care of the daily needs of child - Seto, like feeding him and making sure he gets enough rest. And then there could be some of Seto's employees at KaibaCorp. They might be in a panic at first because their boss has turned into a child, but then they could also contribute to finding a way to reverse the situation, either through their technological expertise or their knowledge of any strange occurrences that have happened in the company before.
In a 'Seto gets turned into a child fanfiction', the plot might revolve around Seto's own struggle to adapt to his new form. He's used to being in control and powerful, but as a child, he has limited abilities. He could try to communicate with others about what happened to him, but with his child - like speech and behavior, it becomes a challenge. His friends might have to protect him from those who would take advantage of his vulnerable state.
The plot might involve Seto trying to find Pegasus in this new form. Since Pegasus has a connection to the magical world of Duel Monsters, Seto could believe that Pegasus has the key to changing him back. Along the way, he might have to participate in some sort of duels in his child pegasus form, which would be quite a challenge as he has to adapt to new rules or powers that come with this form.
Obviously, Seto himself would be the main character. He is the one who is getting grounded, so the whole story would revolve around him. His family members could also be important characters. For example, his parents or guardians who are the ones grounding him. They would play a role in setting the rules and enforcing the grounding. His friends might also be characters in the story. They could come to visit him while he is grounded or try to convince his guardians to let him go early.
His personality might become more innocent. Without the weight of his usual responsibilities and power, he could be more curious and open - minded. For example, he might be more willing to explore new things instead of being so focused on winning and power as he usually is.
Perhaps Seto got into a fight with a powerful enemy and in the process, he put others in danger. His guardians or the people in charge decide to ground him to teach him a lesson about responsibility. During his grounding, he could start to reflect on his actions and come up with new strategies to face his enemies. He might also discover new things about himself while being alone in his grounded state.
Seto, the brilliant and somewhat arrogant CEO of KaibaCorp, and Tea, the supportive and feisty friend in the Duel Monsters world. Seto is known for his high - tech dueling strategies and his desire to be the best. Tea is always there for her friends and has her own unique charm. In Seto and Tea Lemon fanfiction, these two characters are at the center, and their interactions can range from friendly banter to more complex emotional relationships as the story unfolds.
There could be a young protagonist who is trying to discover his or her roots in relation to the 'seto dharti'. Maybe there is also an older character, like a grandparent, who passes on stories and wisdom about the land. Another possible main character could be someone from outside the area who comes to the 'seto dharti' and has a life - changing experience there.
The main characters are Joey and Seto. Seto is likely to be a complex character, perhaps with his own backstory and personality traits that influence how he treats Joey. Joey, on the other hand, as a pet, might have its own quirks and behaviors that make the relationship with Seto interesting.
Well, clearly Seto Kaiba is a central figure. He has his own goals and ambitions in the story. And then there's Tea. When we say 'Tea Baby' in the fanfiction, it could be a unique take on her character. She might be more impressionable or open - minded in this state, and their interactions, with Kaiba's calculating nature and Tea's new - found 'baby - like' qualities, form the core of the story.
Maybe Seto is trying to understand Yugi better in order to outwit him in some future duel. He could be observing Yugi's mannerisms, strategies, and how he interacts with Yami, all to gain an edge.
