If Raditz survived in fanfiction, he would likely have a complex relationship with Goku. He might start to see the value in Goku's way of life. Goku could try to reform him, and Raditz could slowly become a more positive force in the Dragon Ball Z universe.
Well, one possible fanfic could be about Android 18 and Raditz teaming up against a common enemy. Maybe they initially start off as reluctant allies, but as they fight side by side, they begin to respect each other's strength.
Perhaps in the fanfic, Android 18 uses her combat skills to train Raditz. Since she has a lot of fighting experience, she could help Raditz improve his techniques. This could lead to an interesting dynamic where Raditz becomes more powerful under her guidance.
If Raditz turned good, it would have added a whole new dynamic to the Dragon Ball Z universe. He could have become a valuable ally, sharing his knowledge and skills to help the heroes.
Goku is very important. He is the main protagonist and the one Raditz is after. Piccolo is also crucial as he teams up with Goku against Raditz, which is quite unexpected considering their past. And of course, Raditz himself is a key character as he is the main antagonist in this part of the story.
The main plot points start with Raditz's sudden appearance on Earth. His presence shakes Goku's world as he learns about his true heritage. Their confrontation is a big part of the plot. During the battle, the power struggle between Raditz's Saiyan strength and Goku and Piccolo's combined might is intense. Goku's decision to sacrifice himself by holding Raditz still for Piccolo's special beam cannon not only defeats Raditz but also sends a message about Goku's selfless nature. This event also leads to the introduction of the concept of the Saiyan's ability to come back to life, which is important for the overall Dragon Ball Z storyline.
In some fanfictions, Goku and Raditz could form an unlikely alliance if they were faced with an even greater threat. For example, if a new and extremely powerful enemy emerged that threatened not just Earth but the entire Saiyan race. Raditz, who initially came to Earth with the intention of conquering it, might see the need to team up with Goku to save their home planet. Goku, being the good - hearted Saiyan he is, would be open to the idea if it meant protecting his loved ones.
Common themes in 'Dragon Ball Z Raditz x Bulma fanfic' often include the clash of their different worlds. Raditz comes from a warrior - based Saiyan culture, and Bulma from a more technologically advanced Earth culture. So there could be a theme of how they learn from each other. Also, themes of love against all odds can be present, as their relationship would be quite unorthodox in the context of the original Dragon Ball Z story.
Yes, there are quite a few. You can start by looking on fanfic platforms like FanFiction.net or Archive of Our Own. Some fanfics might focus on alternate universes where Raditz has a different relationship with Bulma and Trunks, perhaps a more friendly or even a mentorship - like relationship. However, the quality can vary greatly, so it's important to read reviews or summaries before diving in.
One common theme is family dynamics. Since Trunks has a family connection with Bulma, and Raditz being an outsider, the fanfics might explore how Raditz fits into or affects that family unit. Another theme could be redemption. Raditz was initially a villain, so fanfics could show him redeeming himself in the eyes of Bulma and Trunks.
