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.
One common theme is the idea of redemption. Frieza is a well - known villain, and in some fanfictions, his relationship with Cell can be a path to him becoming a better being. Another theme could be power dynamics, as both are powerful characters, and their love can change how they view and use their power.
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. For example, he could be paired with characters from other universes, leading to epic battles or unexpected alliances.
It could be Beerus. Since he is a powerful God of Destruction, he would see the union of Frieza and Cell as a threat to the balance of the universe and try to stop them.
Golden Frieza's role in crossover fanfiction worlds is quite diverse. He could be a catalyst for change. If he enters a world full of heroes, his evil nature might force them to unite in a way they haven't before. Or he could be a source of knowledge, having come from a different universe with different technologies or magic systems. His presence always shakes things up, whether it's through his brute strength or his devious mind.
A plotline could start with Frieza hearing about Broly's power and being jealous. He then devises a plan to ambush Broly. But Broly, being extremely perceptive in his own way, senses Frieza's approach and is ready for the fight. As the fight progresses, Frieza realizes that Broly is much stronger than he expected and has to use all his dirty tricks to try and win. Or perhaps the plotline could involve Broly being captured by Frieza's forces, and then Broly breaks free and goes on a rampage against Frieza and his minions.
One idea could be that Frieza and Cell team up to take over the universe in a new and unexpected way. They combine their powers and intelligence to outwit all the other powerful beings.
It depends on different factors. Cell has the ability to regenerate and absorb other beings to become stronger. This makes him a very adaptable enemy. However, Frieza is known for his cunning and his ability to quickly develop new forms with greater power. So, in a sense, they are both equally threatening in different ways.
Another thing that could occur is that they end up fighting each other anyway. Their egos are so big that they might not be able to tolerate sharing the spotlight. Cell could see Frieza as a threat to his own plans of domination, and Frieza would not want to be second to Cell. So, a battle between them could be epic and destructive.
