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.
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.
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.
The allure lies in the fact that we can see these two powerful villains in new situations. In fanfiction, they might interact with characters from other universes, which is really cool. It expands the Dragon Ball Z universe in ways the original didn't.
Fanfiction also allows for different endings to their stories. Instead of their fates in the original series, they could be redeemed in some fanfictions. Picture Frieza actually learning to care about others and using his power for good. It's a different take on their characters that fanfiction can offer.
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 of the main themes is the clash of generations. Goten represents the new generation of Saiyans while Frieza is from an older, more menacing era. This creates an interesting dynamic. Survival is also often a theme, as Goten has to fight to survive against Frieza's brutal attacks. Additionally, the theme of justice can be seen, where Goten is fighting for what he believes is right against Frieza's tyranny.
Sure. You can start by looking on fan - fiction platforms like FanFiction.net or Archive of Our Own. Just search for 'frieza uchiha' and you'll likely find a variety of stories written by fans.
One idea could be that after the fusion, they have to deal with a new, even more powerful enemy that is threatening the entire universe. Their combined powers give them unique abilities that they have to learn to control quickly.
