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.
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.
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.
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.
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.
I'm not entirely sure specifically what 'oc cooler fanfic' is about without more context. It could potentially be a fan - created story (fanfic) related to an overclocked (oc) cooler, perhaps in the context of computer hardware where someone has written a fictional piece about a cooler that has been overclocked. But it really depends on the specific fandom or area of interest it pertains to.
One thing that can make a Harry Potter fanfic cooler is an alternate universe setting. Imagine if the wizarding world was set in a steampunk style, with wizards using magic-infused steam-powered devices. Also, a fanfic that delves deeper into the backstories of minor characters and makes them central to the plot can be really cool.
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.
Yes, there are likely 'Bardock Kills Frieza' fanfics out there. The Dragon Ball universe has a huge fan base, and many fans like to create alternative storylines. You can try searching on fanfic websites like FanFiction.net or Archive of Our Own.
