One popular theme is crossover, where characters from Dragon Ball Z and One Piece meet and interact. It's really exciting to see Goku and Luffy team up or fight against each other. Another theme is 'what if' scenarios, like what if a certain character had different powers or made different choices.
Another popular theme is Bardock's backstory. Exploring his life on Planet Vegeta before its destruction, his relationships with other Saiyans, and his rise through the Saiyan ranks. Some fanfics might focus on his relationship with his wife and how that affected his decisions. This can add a lot of depth to his character and make him more than just a tragic figure from Goku's past.
The new storylines that can be created. For example, a new villain could emerge that requires the combined efforts of both the One Piece and Dragon Ball Z crews to defeat. This could involve battles in different settings from both universes, like fighting on the Grand Line and also in the Hyperbolic Time Chamber. It gives a whole new perspective to the existing story arcs of both series.
The character interactions are really fascinating. Picture Vegeta trying to understand the laid - back attitude of the Straw Hats. Also, the concept of different types of power systems colliding. Ki from Dragon Ball Z and Haki from One Piece meeting in one story can lead to some really creative and exciting plot developments. It often makes for unique and unpredictable storylines that keep readers hooked.
Well, time - travel is also quite a common theme. Writers like to play around with the idea of characters going back in time to change events, which can lead to all sorts of interesting plot twists. And of course, there's the theme of friendship. In Dragon Ball Z, friendship is a powerful force, and fanfics often explore deeper aspects of the friendships between characters like Goku and Vegeta, or how the Z - fighters support each other in different situations.
One of the popular pairings is Goku and Luffy. They are the main protagonists of their respective series and fans like to imagine them as friends or even more in some fanfics. Their combined strength and different ways of approaching challenges make for an exciting relationship to explore.
A less common but still interesting theme is the female Majin's connection to other dimensions. In some fanfictions, she has the ability to travel between dimensions. This allows for really unique storylines as she can bring back knowledge or powers from other worlds. It also creates a lot of mystery as the other dimensions are often filled with unknown threats and allies.
One popular pairing is Naruto and Goku. People like to imagine them as friends or even training partners. Another is Sasuke and Vegeta. They both have that cool, brooding personality.
Goku from Dragon Ball Z is often a popular choice. His powerful Saiyan abilities and his never - give - up attitude make him a great character for fanfics. In Bleach, Ichigo is also very popular. His journey from a normal high school student to a powerful Soul Reaper is an appealing story arc. So in crossovers, these two are often the focus.
Goku is likely still one of the most popular characters. His determination and constant pursuit of strength make him a fan favorite even in fan - made stories. His ability to adapt and find new ways to become stronger always keeps the story interesting.
One popular trope is the 'powerful female Saiyan' trope. Fans like to write about female Saiyans who are just as strong, if not stronger, than the male Saiyans in the series. They often go through intense training arcs and show off their amazing powers. Another is the 'romance' trope. It could be a female Saiyan falling in love with a male character from the series, like Goku or Vegeta, and their relationship develops in a unique way compared to the canon relationships.
