One common theme is growth. Both Mondo and Chihiro are characters that can develop a great deal, and in fanfics, their relationship often helps them grow. For example, Mondo might become more understanding and less impulsive, while Chihiro becomes more confident.
Another theme is mutual support. They often find themselves in situations where they need to rely on each other. In some fanfics, this is shown through difficult school projects or dealing with personal issues. Their relationship evolves as they become each other's pillars of support, and this theme is central to many 'ishimaru x mondo fanfic' stories.
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.
Frieza's victims in the manga included many powerful fighters. For instance, he eliminated Dende. His actions were driven by his cruel and power-hungry nature.
Frieza turning good in fanfiction would be a major game-changer. It might involve a character arc where he realizes the error of his ways and strives to make amends, adding depth and complexity to his persona.
One great Mondo x Chihiro fanfic is 'A New Bond'. It focuses on how Mondo and Chihiro's relationship develops in a post - game scenario. They support each other through the challenges of rebuilding their lives after the events in the game.
One great 'ishimaru x mondo fanfic' is 'The Unlikely Bond' which beautifully explores their relationship development. It shows how their different personalities gradually draw them closer.
The combination of Frieza, a character from a very different universe, with the RWBY setting makes it unique. RWBY has its own set of rules, powers, and characters. When you introduce Frieza, who has his own brand of power and villainy, it creates a whole new dynamic. For example, his ability to transform and his extreme power level contrast with the more gradually developed powers in RWBY.
There's a fanfic where Frieza arrives in the RWBY world and tries to take over. He starts by sizing up the Huntsmen and Huntresses as potential threats or pawns. In this fic, the author does a great job of showing how Frieza's cold and calculating nature clashes with the more idealistic characters in RWBY. It's a really engaging read if you like that sort of crossover concept.
