Another interesting one is 'Beyond Enemies'. This fanfic takes place after the events of the main series. Goku and Frieza are forced to interact in a new situation, like a cosmic tournament where they have to represent their respective races. It shows their growth and how they might see each other in a different light.
Then, introduce some shared experiences. Maybe they get trapped in a strange dimension together. In this new and dangerous place, they have to rely on each other's strengths. Goku's physical power and Frieza's cunning could be the keys to their survival. As they go through these experiences, they start to see each other in a new light and their relationship begins to change.
Well, it could lead to a major shift in their relationship. Maybe Frieza would start to respect Goku or even team up with him.
One common theme is redemption. Frieza is often portrayed as having a chance at redemption through his interactions with Goku. For example, in some fanfics, Goku's unwavering belief in the good in people (or in Frieza's case, beings) starts to make Frieza question his own evil ways.
One idea could be that Frieza and Goku are forced to team up against a new, even more powerful enemy. They start off hating each other but gradually learn to respect each other's skills.
Yes, Goku does kill Frieza in the manga.
Another good one is 'Frieza and Cooler: Allies in a New World'. This fanfic imagines a scenario where they have to team up against a greater threat than they've ever faced before. It's full of action and shows how their powers combine in different ways.
I'm not sure about a specific 'goku x kefla fanfic' to recommend. You could try searching on fanfiction websites like Archive of Our Own or FanFiction.net. There might be some interesting ones there.
There's a fanfic where Frieza arrives in the RWBY world and tries to take over. He starts by sizing up the Huntsmen and Huntresses as potential threats or pawns. In this fic, the author does a great job of showing how Frieza's cold and calculating nature clashes with the more idealistic characters in RWBY. It's a really engaging read if you like that sort of crossover concept.
One great 'Frieza fanfic' is 'The Redemption of Frieza'. It explores a different side of Frieza where he has a chance at redemption. Another is 'Frieza's New Empire' which shows Frieza building his power in a new and unexpected way. And 'Frieza and the Time Rift' is also interesting as it involves Frieza getting caught in a time - traveling adventure.
Sure they do. This fight is a major event and showcases the power and determination of Goku and Vegeta against the formidable Golden Frieza.
