A common trope is the 'Secret Crush' trope. Maybe Caulifla has a secret crush on Kale but is too proud to admit it at first. Or vice versa. Also, the 'Injury and Care' trope can be found. If Caulifla gets injured, Kale taking care of her can lead to a tender moment and the start of a yuri - themed relationship. There's also the 'Misunderstanding' trope. For instance, they might misunderstand each other's actions as signs of romantic interest when it was just friendly at first, which then leads to some interesting plot developments.
One popular trope is the 'Training Bond' trope. Since they often train together in the original series, in yuri fanfics, this can be a starting point for deeper emotional connections. Another is the 'Protect Each Other' trope. For example, Kale might be in a dangerous situation and Caulifla would go to extreme lengths to save her, which then leads to a realization of deeper feelings. And the 'Shared Power' trope can also be common. When they combine their powers, it can be a moment of intense closeness and a catalyst for romantic feelings in fanfics.
First, study their characters. Know their personalities, their goals, and how they interact in the original work. For example, Caulifla is bold and confident while Kale is more shy and reserved. You can use these traits to build their relationship in the fanfic. Then, come up with a basic plot idea like a new adventure they go on together that brings them closer. Start with a strong opening, like a moment of conflict or a sudden realization between them.
One possible theme could be friendship and camaraderie evolving into a deeper bond. Since they are all characters from the same universe, they might have shared adventures that bring them closer in the fanfic.
Finding a 'cabba caulifla kale threesome fanfic' might be a bit of a challenge. Fanfics often require some searching through different fan - created platforms. You could start by looking at popular fanfic websites related to the series these characters are from. But keep in mind that not all fanfics are well - organized or easy to find. Also, the nature of such a threesome concept might not be as common as other types of fanfics, so it might take some time and effort to come across one, if it exists at all.
One common theme is friendship. They are all Saiyans (or part - Saiyan in Gohan's case), and the fics often explore how they bond over their shared heritage. Another theme is growth. Gohan can help Kale and Caulifla grow as fighters, and they can also help him in different ways, like making him more confident in his Saiyan side.
Well, one possible plot could be a training arc where Goku helps Caulifla and Kale to master new forms. They could travel to different planets for special training. Goku could share his Saiyan knowledge with them, and together they face off against new powerful enemies.
A frequently used trope for Madoka Magica Yuri OCs in fanfiction is the 'opposites attract' scenario. For example, an OC who is very outgoing and confident might be attracted to a more reserved and shy character, and vice versa. This creates a lot of tension and interesting character dynamics in a yuri relationship. Another is the 'forbidden love' trope. Maybe the Yuri OC is from a different faction or has a secret that makes her relationship with another girl difficult or dangerous, adding an extra layer of drama to the story.
One popular trope is the 'rivalry - turned - friendship' where they start as rivals in the Pokémon world but gradually become friends. Another is the 'time - travel' trope, where one of the characters might go back in time and change things related to their relationships. And the 'love triangle' trope also appears sometimes, usually involving some form of romantic tension between the three characters.
One popular trope is the 'enemies - to - lovers' aspect. Since Draco and Harry were enemies in the original series, seeing them cuddle after going through a journey of changing their relationship is really appealing. Another is the 'hurt/comfort' trope. Maybe one of them is injured or emotionally distraught, and the cuddling is a form of comfort.
The 'hurt/comfort' trope is quite common too. Maybe Cal gets injured during a battle, and Merrin has to take care of him, which deepens their relationship. Also, the 'soulmate' trope can be found in some fanfics, suggesting that they are meant to be together on a deeper, almost spiritual level, which ties in well with the Star Wars universe's themes of destiny and the Force.
One common trope is the survival aspect. Just like in the original 'Highschool of the Dead', in fanfics, the gamer characters often have to use their gaming skills to survive in a zombie - infested world. For example, they might use their knowledge of strategic games to plan escapes or fortify their hiding places.
