One common theme is the blending of different power systems. Goku has his Saiyan powers and Usagi has her Sailor Moon powers. Fanfictions often explore how these powers interact when they are married. For example, they might combine their powers to defeat a powerful villain. Another theme is the cultural clash. Goku comes from a more action - based, martial - arts - focused world, while Usagi is from a more magical girl - type world. How they bridge these differences in their married life is often explored.
There's also a fanfiction titled 'Goku - Usagi: United Worlds'. It starts with an unexpected encounter between Goku and Usagi, which leads to them falling in love and getting married. The story delves into how their different friends and families from their respective series react to their union. It's interesting to see how the Dragon Ball characters interact with the Sailor Moon characters in this fictional scenario.
Another theme is cultural exchange. Goku is from a more action - oriented, martial - arts - based culture in Dragon Ball, while Usagi is from a magical girl anime with a different set of values. Fanfictions may play with how they introduce their respective cultures to each other.
Another theme is the culture clash. Goku comes from a martial - arts - focused, somewhat simple - living world in Dragon Ball, while Usagi is from a more magical and girly world in Sailor Moon. Fanfictions play with this difference, like when they first meet and don't understand each other's ways of doing things. It can lead to some really funny and also some really touching moments as they learn about each other.
Yes, Archive of Our Own (AO3) is also a great source. You can search for 'usagi x goku' and get a bunch of results. Some fanfictions might focus on their friendship and how they could learn from each other's skills and strengths. For example, Goku's martial arts skills and Usagi's leadership and magical abilities could be combined in interesting storylines.
There's also 'Goku and Usagi's Adventure' which is quite popular. In this fanfiction, the author focuses on the relationship development between Goku and Usagi. It starts with their initial encounter which is full of misunderstandings due to their different cultures, but as the story progresses, they start to understand and respect each other more, and it leads to a really heartwarming adventure together.
In their married life, Seiya and Usagi would create a unique family. Since they both have such strong identities in the Sailor universe, they would combine their powers and wisdom to raise their children (if they have any) to be strong and kind. Their relationship would be a blend of the excitement of their adventures and the warmth of domestic life. They would often reminisce about their past battles and how far they've come together. Their love would be a source of strength for the entire Sailor community.
There probably is. Fanfiction writers love to explore different pairings and scenarios. Since Goku is a very popular character and 'Melee' might refer to something specific in a certain fandom, it's not unusual for someone to write a story about Goku getting married within that context. However, the quality and nature of such a fanfiction can vary greatly.
If Goku married a Saiyan in a fanfiction, it might bring new challenges and adventures. Maybe there'd be family feuds or combined efforts to protect their kind. It really depends on how the author envisions their relationship and the subsequent story arcs.
