A fanfiction could explore Pan's journey as a Super Saiyan in Dragon Ball GT in relation to her family heritage. She might struggle with the pressure of living up to the Saiyan legacy. Her Super Saiyan transformation could be a turning point where she finally accepts her role and uses her power to protect those she loves, while also learning about the true meaning of being a Saiyan.
One great fanfic idea could be a female Super Saiyan from a different universe arriving in the Dragon Ball Z universe. She could initially be seen as a threat but then team up with Goku and the others to fight a new, powerful enemy. Maybe she has unique abilities that are different from the male Super Saiyans, like a more energy - efficient transformation or a special healing ability while in Super Saiyan form.
One idea could be Gohan struggling to control the new power of the Super Saiyan God. He might accidentally cause some destruction while training and then have to deal with the guilt and the fear of his power getting out of control.
She could go on a quest to find a lost Saiyan artifact that can only be accessed by a Super Saiyan. This would take her to different planets and introduce new characters.
A plot could be that Gohan is suddenly bestowed with the Super Saiyan God power during a moment of great crisis. Maybe when the Earth is on the verge of being destroyed by an unknown force. He then has to quickly learn how to use this power to save the planet. He could face challenges like the power draining his energy too quickly at first, and he has to find a way to sustain it long enough to defeat the enemy.
It could be a rogue Saiyan from a forgotten part of the Saiyan history. This Saiyan might have a grudge against the Z - fighters and their descendants, like Pan. He could have developed his own version of the Super Saiyan 4 power in a more evil way and wants to prove his superiority by defeating Pan.
Well, a really popular one is a fanfiction that I read once where the female Super Saiyan teams up with Goku to fight a new, powerful enemy. It was really cool to see how the author wrote her character, with her own unique fighting style and personality. And then there's this other fanfic that explores what would happen if a female Super Saiyan was the first to reach the Super Saiyan God level. It's full of exciting battles and interesting character development.
A plotline could be where a female Super Saiyan discovers a hidden power within her Super Saiyan form that allows her to time - travel. She uses this ability to go back in time to prevent certain tragedies from happening in the Saiyan history, like the destruction of Planet Vegeta. This would change the entire Dragon Ball Z timeline and create new and exciting story developments.
A fanfiction might explore the idea of Bardock seeing Goku's life through a time - space rift. He witnesses all of Goku's battles and the friends he makes. Bardock is filled with pride but also realizes that Goku has a different path than the traditional Saiyan way. This makes him question the Saiyan culture he once knew. Meanwhile, Goku starts to have strange dreams about his father, which leads him to search for more about his Saiyan heritage.
One idea could be Pan discovers a hidden power within herself that allows her to transform into a unique form related to Super Saiyan 4. Maybe she has to go on a quest to find the knowledge to fully control this power. Another plot could involve Pan traveling to a different dimension where Super Saiyan 4 is the norm and she has to prove herself among stronger Saiyans there.
