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.

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.
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.
One possible plot could be that Yamcha, known for his tenacity, somehow ends up in a situation where he has to team up with Frieza. Maybe they are both forced to face a common enemy that is even more powerful than Frieza at his peak. This could lead to an interesting dynamic as Yamcha tries to get Frieza to work as a team, while Frieza is his usual self - conniving and power - hungry. Their interactions would be full of tension and mistrust at first, but over time, they might develop an odd sort of respect for each other.
