Well, one possible fanfic could be about Android 18 and Raditz teaming up against a common enemy. Maybe they initially start off as reluctant allies, but as they fight side by side, they begin to respect each other's strength.
Obviously, Android 21 is one of the main characters. She's the center of this fanfiction. Also, Goku and Vegeta are likely to be involved as they are the mainstays in the Dragon Ball Z universe. They would interact with Android 21 in different ways, like fighting against her or trying to understand her motives.
One great Android 18 fanfiction is 'Android 18's New Life'. It shows her adapting to a peaceful life after the battles in Dragon Ball Z. The story focuses on her relationships with the other characters, especially her family life with Krillin and their daughter. It's really heart - warming to see her in a different light than just a fighter.
I can't really point to one specific fanfiction as there are so many out there. But you can start by looking at popular fanfiction websites and filtering for Dragon Ball Z, Krillin, and Android 18. Check the reviews and ratings to find a good one.
One possible plot could be that Android 21, with her unique powers, teams up with Goku to face a new and powerful enemy. They might have to combine their strength and fighting techniques to defeat this foe.
First, you need to have a clear concept of your OC (Original Character). Decide on their appearance, personality, and backstory. For example, if your Android OC is a female, you could make her have a sleek, silver - haired look and a cold but secretly kind personality. Then, think about how they fit into the Dragon Ball Z universe. Will they be an ally or an enemy? Maybe they start as an enemy but later become an ally due to some events. Also, study the existing power systems in Dragon Ball Z and create a unique power for your OC. This could be a new type of energy blast or a special ability like self - repair that is related to being an Android. And don't forget to include some interactions with the main characters. These interactions can drive the story forward and add more depth to your fanfiction.
Well, in some fanfictions, Android 21 might be depicted in new power - up scenarios. For example, she could form unexpected alliances with other Z - fighters. This would change the power dynamics in battles and lead to really cool fight sequences.
You can try some fanfiction websites like FanFiction.net or Archive of Our Own (AO3). They usually have a wide range of fanfictions for various fandoms including Naruto and Dragon Ball Z. Just search for the relevant tags on these platforms.
Another way is that Goku could use the Spirit Bomb. He could gather energy from all living things on Earth and nearby planets. Android 21, being an artificial being, might not be able to withstand the pure energy of the Spirit Bomb. However, she could try to absorb the energy, but if Goku can overload her absorption capabilities, it would be his victory.
In a fanfiction scenario, Goku and Android 21's fight could attract the attention of other Z - fighters. Vegeta, for example, might be reluctant to help Goku at first but then realizes the danger Android 21 poses to the entire planet. Goku could also try to reach out to Android 21's good side, as he has a history of trying to redeem his enemies. This could add an interesting moral dilemma to the story, whether to fight or try to save her.
