Redemption is also seen. Given their villainous nature, some fanfics have them try to redeem themselves, either for personal growth or to change the way others view them. This could involve them making amends for past atrocities they've committed in the Dragon Ball 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.
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 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.
Power is a very common theme. Fans often explore who would be more powerful in different situations or how they could combine their powers. Another theme is rivalry, as they are both powerful villains in the Dragon Ball universe. Their personalities also play a big role, with themes of pride and ego often coming up.
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.
One common theme is power struggle. Given Frieza's obsession with power and Sakura's own growth in power, their interactions often revolve around this. Another theme could be redemption, where Sakura tries to make Frieza see the good side of things.
Power struggles are a common theme. Since Frieza is extremely powerful, when he's crossed over into other universes, there's often a battle for dominance. For example, in crossovers with superhero universes, he'll fight against heroes who also have great power.
Power and domination are common themes. Since Frieza is known for his lust for power in the original series, fanfictions often expand on this. They might show him seeking new ways to increase his power, like finding ancient artifacts that grant him additional abilities. Another theme is revenge. Frieza might be seeking revenge against Goku or the Saiyans for his previous defeats. This can lead to intense battle - oriented storylines.
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.
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.
