Another one is 'Love's Surprise'. Here, the krillin and 18 kiss happens in a rather unexpected situation. It's a short but really cute fanfiction that gives a new perspective on their relationship.
Well, for one, their relationship in the original story has a lot of potential for exploration in fanfiction. Their different personalities, Krillin being the kind - hearted and often comical character and 18 being more reserved yet strong, make their interactions, especially a kiss, very exciting to read about.
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.
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.
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.
Well, one possible plot could be that they have a simple yet beautiful wedding on Kame House island. All their friends from the Z - fighter group come to celebrate. Krillin might be super nervous and 18 would be the calm one, reassuring him. And then they could start their life together, with Krillin teaching martial arts to local kids and 18 helping out in the community in her own unique way.
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.
For Krillin, he could be developed by showing his growth in confidence. Maybe he takes on bigger threats without hesitation. For Android 18, her softer side could be explored more, like her maternal instincts if they have a child.
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.
In this fanfiction, Tien could be Krillin's best man. Tien is a very loyal friend and his serious nature could add some stability to the wedding party. As for 18, Videl could be the maid of honor. Videl is young and energetic and could bring a lot of fun to the pre - wedding and wedding day events, while also being a good friend to 18.
