Family dynamics is another. As brothers, their relationship can be complex. Some fanfics show loyalty between them, while others highlight jealousy or rivalry. For example, a fanfic might explore how Frieza's jealousy of Cooler's strength affects their relationship.
Power is a common theme. Since both Frieza and Cooler are powerful characters, many fan fictions explore how they gain more power, or how they compare their power levels. Another theme is family. Their relationship as brothers often plays a big part, like in stories about their rivalry or their attempts to cooperate. Redemption can also be a theme, especially for Cooler in some fictions where he tries to make up for his past actions.
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.
One popular 'Frieza and Cooler' fan fiction is 'The Brothers' Rivalry Extended'. It delves deeper into their relationship, showing how their competitiveness affects their actions within the Frieza Force. Another is 'Cooler's Redemption', where Cooler tries to atone for his past misdeeds and Frieza has to deal with this new side of his brother. There's also 'Frieza and Cooler: A New Alliance' which imagines them teaming up against a common, powerful enemy that threatens their rule in the universe.
To develop Cooler further, he could be given a redemption arc. Maybe he starts off as a villain but gradually realizes the error of his ways. He could befriend some of the younger Z - fighters who look up to him despite his past. This would force him to be a better role model and in the process, he would change and become a more complex and interesting character.
For Yamcha, you can focus on his growth from being a bit of a comical character to a more serious and respected fighter in the context of his relationship with Frieza. Maybe he learns from Frieza's cold and calculating nature how to better strategize in battles. For Frieza, his development could be about him learning to care for someone other than himself. He could start to see Yamcha as an equal, which is a huge shift from his usual superiority complex.
I'm not entirely sure as 'si oc cooler fanfic' is rather unclear. It could potentially be a fanfic (fan - created fiction) related to a self - insert (si) in a story involving overclocking (oc) and a cooler. But without more context, it's hard to say for sure.
One water cooler horror story could be about a haunted office building. People heard strange noises near the water cooler at night. They said it sounded like someone was whispering, but when they checked, no one was there. It was really spooky.
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.
Golden Frieza in crossover fanfiction often brings a new level of power and intrigue. His golden form is a significant power - up in the original series, and in fanfiction, it can be used to create interesting scenarios.
