One idea could be that Kuriza, as Frieza's son, tries to redeem his father's name. He could start by training hard to become stronger than Frieza ever was. In the fanfiction, he might encounter the Z - fighters and instead of fighting them, he asks for their help in changing the ways of the Frieza race. He wants to break the cycle of tyranny his father started.
The fanfiction might center around a power struggle between Frieza and Kuriza. Perhaps Kuriza wants to take over his father's empire but Frieza is not ready to let go. This could lead to an intense family drama with battles and political intrigue within the Frieza race.
A fanfiction could involve Vados taking Goku on a journey through different timelines to show him the consequences of his actions. Goku would see alternate versions of himself and his friends. This experience could make him more cautious and strategic in his battles back in his own timeline. Vados would be like a guide, teaching Goku about the importance of balance and how his power affects the multiverse.
One great 'Dragon Ball Frieza Fanfiction' is 'Frieza's Redemption'. It explores a different side of Frieza where he tries to atone for his past sins. It's interesting to see how the author develops his character in a new way, away from his typical villainous role.

For example, teaming up with former enemies or facing new threats. Also, fans are always curious about what could have been if Frieza had made different choices, and fanfiction allows them to explore those ideas.
