There could be a fan fiction where Android 18 and Krillin go on a quest to find a rare artifact. Along the way, they meet other characters from the Dragon Ball universe. They have to solve puzzles and fight battles to get to the artifact. This would show their relationship growing stronger as they rely on each other throughout the adventure.
A great fan fiction idea is that Android 18 and Krillin enter a martial arts tournament together. They face opponents who underestimate them because of their relationship. But they prove everyone wrong by using their unique skills in combination. Android 18's android strength and Krillin's martial arts techniques make them an unbeatable team.
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.
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.
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.
In fan fiction, their characters can be developed by giving them new goals. Android 18 could aim to become a better mother to Marron, and Krillin could strive to be a more respected martial artist in the community. They could support each other in achieving these goals. Android 18 could use her strength to help Krillin train, and Krillin could offer his wisdom to Android 18 in parenting. This would add new layers to their characters and their relationship.
One interesting Super Krillin fan fiction could be about Krillin becoming the strongest Z - fighter through a new kind of training. Maybe he discovers a hidden power within himself that no one knew existed.
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.
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 great Android 18, Krillin and Marron fanfic could be one that focuses on their family outings. For example, it might show Krillin taking Android 18 and Marron to a picnic by the lake. They could have cute interactions like Marron trying to feed the ducks while Android 18 watches protectively and Krillin just enjoys the moment with his family. Another could be a fanfic where they face a new threat in their city and they all work together to overcome it, with Android 18 using her strength, Krillin his martial arts skills, and Marron showing her cleverness in some way.
One interesting storyline could be about Naruto having a different power origin. For example, instead of being the host of the Nine - Tails, he might gain his power from an ancient sage. This could change the whole dynamic of his character development and relationships in the story.
A great WWE fan fiction storyline could be about a wrestler who loses their confidence after a series of defeats. But then they go on a journey of self - discovery, training with an old - school trainer. Through this process, they not only regain their confidence but also develop a new and more aggressive in - ring style, coming back stronger than ever to reclaim their place in the WWE.
One interesting storyline could be Pepsiman traveling to different dimensions to spread the joy of Pepsi. Maybe in one dimension, everything is made of Pepsi and he has to save it from an evil force that wants to turn it into a different drink.
