Bulma could also be a common character paired with Krillin. Bulma is very intelligent and could potentially help Krillin figure out how to time travel better or she might be the one who creates the time - travel device in the first place. And she could use her resources to help Krillin in his time - traveling adventures.
In the manga, Krillin doesn't stop training. His sense of duty and the need to protect his comrades push him to keep improving his skills and strength.
Maybe a story where 18 and Krillin decide to open a martial arts school. They have to deal with different types of students, and it shows their relationship growing as they work towards a common goal. It can include how Krillin uses his knowledge and 18 her strength to train the students.
Their relationship can be explored by showing how they support each other in daily life. For example, Krillin could be shown helping 18 with her android - related issues, like dealing with any glitches or upgrades. And 18 could be there for Krillin when he has self - doubt about his martial arts skills.
A really interesting fanfic idea could be set in a post - apocalyptic version of the Dragon Ball universe. Android 18 and Krillin have to fight to protect the few remaining survivors. They use their unique skills, with Android 18's android powers and Krillin's martial arts. Their relationship becomes a source of hope for those around them, as they prove that love can still exist even in the harshest of times.
Well, Goku and Krillin are fictional characters from an anime, known for their fighting skills and adventures in a fantastical world. 'Pulp Fiction' is a cult classic movie with its own unique style of storytelling. One could say that the idea of a hero's journey might be a very loose connection. Goku and Krillin are on a journey to become stronger and protect their world, while the characters in 'Pulp Fiction' are on their own journeys within the seedy underworld, dealing with crime, redemption and survival.
In some fanfictions, Krillin might time travel to the era of the Saiyans' first arrival on Earth. He could then try to change the outcome of the battle, perhaps by warning Goku earlier or finding a way to defeat the Saiyans with his own skills and wits. This would be a really exciting story as it would completely change the course of the Dragon Ball universe.
