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.
In some fanfictions, the focus might be on how Android 18's android nature affects their relationship. For instance, there could be a story where Krillin has to deal with Android 18 having a malfunction that makes her act differently. He then has to find a way to fix her without losing the essence of who she is, and this creates a lot of emotional and action - filled moments in the fanfiction.
Yes, there are. For example, some fanfictions might explore Krillin's character in new and unique ways, like giving him new powers or putting him in different situations within the Dragon Ball universe.
Yes, they are. In the novels, there are often more detailed descriptions of the characters' thoughts and feelings. For instance, when Gohan is in a tough battle, we might get a more in - depth look at his fears and determination in the novels compared to the anime.
The main difference is that the abridged fanfiction of Dragon Ball Z is likely to have a different take on the story. So when Akatsuki watches it, they're seeing a more modified version. Dragon Ball Z is the original, while the abridged fanfiction may cut out some parts, add new jokes or even change character personalities a bit.
There are no such inappropriate 'Straight Shota' stories in the official Dragon Ball Z canon. Dragon Ball Z mainly focuses on epic battles, power-ups, and the adventures of Goku and his friends to protect the Earth from various villains.
One love story in Dragon Ball Z could be the relationship between Goku and Chi - Chi. Chi - Chi has loved Goku since they were young. She was determined to marry him and finally did. Their love story is unique as Goku is often more focused on training and fighting to protect the Earth, but Chi - Chi is there to support him in her own way, like taking care of their family and making sure Goku doesn't neglect his family duties completely.
One alternative is to focus on character backstories. You could write about the early days of Piccolo, how he came to be the way he is. Another option is to do crossovers with other non - sexual universes. Maybe a story where the Dragon Ball Z characters meet characters from a magical anime world and they have to work together to solve a problem. Also, you can write about the relationships between the characters in a platonic way, like the deepening of the friendship between Gohan and Krillin.
