Then, introduce some shared experiences. Maybe they get trapped in a strange dimension together. In this new and dangerous place, they have to rely on each other's strengths. Goku's physical power and Frieza's cunning could be the keys to their survival. As they go through these experiences, they start to see each other in a new light and their relationship begins to change.
In some lemon fanfiction, their interaction can be filled with tension. Goku, being the good - natured Saiyan, may be initially wary of Frieza. But as the story progresses, they might find common ground. For example, they could start to respect each other's power.
One popular Goku and Frieza fanfiction might be those that explore their unlikely alliance. For example, a story could be about them teaming up against a greater threat in the Dragon Ball universe. In these fanfictions, the authors often play with their characters' personalities. Goku's pure - heartedness could contrast with Frieza's devious nature, creating interesting plot dynamics.
It could develop through mutual admiration for each other's power. Goku is always looking for strong opponents to test himself against, and Female Frieza is no slouch in the power department. As they spar and train together, they might begin to respect each other more. This could lead to a friendship where they exchange fighting techniques and stories of their battles. Over time, this friendship could deepen into a more meaningful relationship where they trust each other completely.
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.
A plot could involve a love triangle where Female Frieza has feelings for Goku, but Goku is oblivious and focused on his own goals. Meanwhile, another character is also interested in Goku. This could lead to a lot of comical and tense situations. Or perhaps Female Frieza challenges Goku to a series of contests not related to fighting, like cooking or dancing, to prove she can be better than him in other areas.
One idea could be that Frieza and Goku are forced to team up against a new, even more powerful enemy. They start off hating each other but gradually learn to respect each other's skills.
