The plot might involve Goku and Android 18 accidentally time traveling during a battle with a new villain who has time - based powers. They find themselves in a time when the Dragon Balls were first created. They have to figure out how to use the power of the Dragon Balls in that time to get back to their own era. Along the way, they meet ancient warriors and learn new fighting techniques. Android 18 might have to deal with her own identity as an android in a time when such technology doesn't exist, while Goku has to adjust to the different power levels and cultures of that era.
Well, the plot could be that Goku and Android 18 are sent back in time by a powerful enemy's time - warping device. They end up in a time when the Saiyan race was still thriving on Planet Vegeta. Goku, being a Saiyan himself, is conflicted about interfering with the past. Android 18, on the other hand, is more interested in finding a way back. But as they stay there, they start to realize that there are things they can do to make the future better, like preventing certain evil Saiyans from doing terrible things that would later have far - reaching consequences for the universe.
One possible scenario in this fanfiction could be that Android 18 and Goku are forced to time travel due to a new threat that endangers the entire universe. They might travel to a time when the Saiyans first arrived on Earth. Goku, with his knowledge of the future, could try to change some events to prevent future disasters. Android 18, with her strength and unique abilities, would be a great ally in this adventure. They might face challenges like dealing with the primitive technology of that time and also having to hide their true identities to avoid disrupting the timeline too much.
One plot could involve time travel. Android 1 travels back in time and meets a younger Goku. At first, Goku is suspicious of her, but as they interact more, they start to care for each other. Android 1 tries to help Goku in his battles against the Saiyans in this timeline. Their love story unfolds as they try to change the future for the better, with their relationship being a key factor in uniting different factions in the fight against greater threats.
Maybe in the fanfiction, Goku accidentally uses a new technique that causes him and Android 18 to be mentally linked. Through this link, they start to understand each other on a deeper level. They then find themselves drawn to each other's strength and determination. But they have to hide their growing relationship from their friends and family who might not understand.
Well, one possible plot could be that Goku realizes his true feelings for Android 18 over time. They might start off as friends who train together. As they spend more time, Goku discovers her softer side that was hidden beneath her tough exterior. And then, they gradually fall in love and decide to get married, facing all the challenges from their friends' surprise and the potential threats from villains who might see their union as a threat to their evil plans.
Maybe in a post - Cell Games world, Android 18 has become more integrated into the Z - Fighters' group. Goku, always open - minded, starts to notice her more as a person rather than an android. They go on a mission together where they are trapped in a dangerous situation. In the heat of the moment, they share a kiss as a sign of their new - found connection and a hope for survival.
A possible plot could be that Android 18 and Goku are thrown into an alternate dimension where they have to rely on each other to survive. In this dimension, they face challenges that test their friendship and fighting skills. Android 18 might learn some of Goku's signature moves and Goku could learn more about the technology within Android 18.
One possible plot could be that Android 18 and Goku time travel to the past to prevent the Androids from ever being created. They might face challenges like dealing with the Red Ribbon Army before they start the Android project. Another plot could be that they travel to a future where the Earth is in ruins and they have to find a way to change the events that led to it. They could also time travel to an alternate timeline where Goku was never sent to Earth and see how that changes everything.
One possible plot could be a story of Goku and Android 21 teaming up against a new and powerful enemy. They start off as reluctant allies. Goku is initially wary of Android 21 due to her being an android, but as they face challenges together, they begin to understand and respect each other's powers. They could learn new techniques from one another and in the end, become friends. This would be a great way to show their growth and the power of friendship across different species in the Dragon Ball universe.
Well, they could end up in different historical events. Maybe they land during the Saiyan - Tuffle war. Kid Goku might be confused but Android 18 could use her knowledge of history (if she has any in this fanfic) to guide them. They could also meet different versions of characters, like a younger Vegeta or Gohan.
Their relationship could become more of a teacher - student dynamic. Goku could teach Android 18 about the ways of the Saiyans and their fighting techniques from different eras during the time travel. Android 18, in turn, could show Goku some of her android - specific skills and how to use them more effectively. This exchange of knowledge could bring them closer and make them a more formidable team.
