If Goku and Android 18 met as kids in fanfiction, it could be a really cute scenario. Goku would likely be excited to meet someone new and different. He'd probably try to share his food with her, like he always does with his friends. Android 18 might be a bit more reserved at first, but Goku's friendly nature would break the ice. They could then start having races or little competitions to see who was faster or stronger. And as they grew up in this fanfiction world, their bond could grow stronger, and they could be important allies in future battles against common enemies.
Well, they might become friends. Goku, being the kind - hearted boy he is, would probably be curious about Android 18. Maybe they'd start training together, with Goku showing Android 18 some of his martial arts moves. And Android 18 could show Goku some of her advanced technology - like knowledge, if she had any in her android form even as a kid. They could also get into all sorts of adventures, exploring the world around them and getting into harmless little troubles.
Well, at first they might be a bit wary of each other. But as time passed, they'd discover their common interests like the pursuit of strength. Goku's positive attitude would influence Android 18, and she would in turn help Goku with things like problem - solving from her android - smart perspective. As they grew older in the fanfiction, this relationship could become a very deep and important one, with them having each other's backs no matter what.
It might also be a story about self - discovery. Android 18 could be exploring her more human side with Goku's influence. Goku, on the other hand, could learn more about the androids and how they are not all just mindless killing machines. The 'lemon' aspect might imply some sort of budding relationship that is full of passion and challenges as they come from very different backgrounds.
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.
Well, it could be a relationship based on power dynamics. Goku is extremely powerful, and Android 21 is no slouch either. They might engage in battles that gradually turn into a form of respect for each other's abilities. And then, this respect could evolve into a deeper connection. For example, Goku could teach Android 21 about the joys of a fair fight, and she could in turn show Goku some of her unique Android - related skills or knowledge.
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.
If Danny Phantom met Goku in a fanfiction, they would likely be curious about each other's powers. Goku might be excited to see Danny's unique ghost abilities, like flying without Ki and being able to turn invisible. Danny, on the other hand, would be amazed by Goku's raw power and his various Super Saiyan forms. They could end up training together, with Goku teaching Danny about Ki control and Danny showing Goku how to use his ghost powers in combat situations.
In this fanfiction, they might have an epic sparring session. Goku could pass on some of his old fighting techniques to Goku Jr.
There could also be a moment of self - discovery for both of them. Goku might see his past self in Kid Goku and realize how far he has come, while Kid Goku could get a glimpse of his future potential through meeting his adult self. They could share stories about their friends and enemies, like how Goku could talk about Vegeta and Frieza to Kid Goku, and Kid Goku could tell Goku about his early battles with the Red Ribbon Army.
Perhaps they would team up against a common enemy. In fanfiction, new threats are often created. They could combine their strength and unique techniques to defeat the bad guy.
