One possible fanfiction could focus on their daily life together. They might have a sweet morning routine, like making breakfast and chatting about their plans for the day. Krillin could be shown as a very caring partner, always looking out for Android 18's well - being. For example, he might bring her a flower he found during his training, just to make her smile.
Another idea for the fanfiction is that they go on an adventure together. Maybe they travel to a new place in the Dragon Ball world that they haven't explored before. Along the way, they face some challenges and have to rely on each other's strengths. Android 18 uses her powerful android abilities, while Krillin uses his martial arts skills and his wits.
The fanfiction could explore their relationship growth over time. How they gradually became closer and more in - sync with each other. It could show how they supported each other through tough times, like when Krillin was worried about protecting the Earth from new threats and Android 18 was there to give him confidence and strength.
Their relationship could grow deeper as they face the challenges of pregnancy together. Krillin might become more in tune with 18's needs, and 18 could see a new side of Krillin's caring nature.
There are likely some fanfics about Krillin and Android 18 that focus on their relationship in a non - sexual and family - friendly way. You can try looking on fanfiction websites like FanFiction.net or Archive of Our Own. Search for stories tagged with 'Krillin' and 'Android 18' to find ones that might interest you.
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.
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.
One good theme could be their family life. How they raise Marron and deal with the daily challenges of being parents in the Dragon Ball world.
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.
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.
One interesting storyline could be about their family life. Maybe Android 18 and Krillin decide to take a vacation with their daughter, Marron. They could face various challenges during the trip, like dealing with villains who target their family. Another could be a story where Krillin has to rescue Android 18 from an old enemy who has found a new way to control her. This would test their love and Krillin's strength.
