There are quite a few. You can check out fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Dragon Ball Z Young Justice' on those platforms and you'll find a variety of stories, from crossovers where the characters meet and team up, to stories that explore how the power dynamics of Dragon Ball Z would work in the Young Justice universe.
I really like 'The Fusion of Two Worlds'. In this fanfiction, the technology in Young Justice's world and the ki powers from Dragon Ball Z are combined in a unique way. It starts with a strange portal opening up and the characters slowly getting to know each other's abilities. There are some great character interactions, like when Robin and Gohan start comparing their detective and martial arts skills.
The power combinations. When you mix the super - powered characters from Dragon Ball Z with the diverse abilities in Young Justice, it can lead to some amazing scenarios. For instance, a character like Gohan using his ki blasts while working with Miss Martian's telepathy to take on an enemy.
The power - up moments. For example, when a Young Justice character witnesses a Saiyan going Super Saiyan for the first time. It's a moment of pure awe and it adds a new level of excitement to the story.
One idea could be a crossover where Goku meets Superman. They could have a friendly sparring match to test each other's strength. Maybe they start off misunderstanding each other's motives but then realize they are both protectors of their respective universes.
Maybe there's a rift in the multiverse that merges parts of the Dragon Ball Z world and the DC Universe. The Z Fighters and the Justice League initially think they are enemies due to misunderstandings. For instance, when Goku first meets Batman, Batman might mistake Goku's carefree attitude for recklessness. But as they gradually figure out the situation, they team up to close the rift and fight off threats that are emerging from the merged worlds.
A cool plot might involve a rift in space - time that pulls the Dragon Ball Z world and the DC Universe together. Vegeta could be at odds with Wonder Woman at first, seeing her as a rival in terms of strength and combat skills. The Justice League and the Z Fighters then discover that an ancient evil force from both of their universes' pasts has been awakened. They must learn to work together, with Gohan and Robin sharing their intelligence to figure out a plan. The Saiyans' transformation abilities and the Justice League's various powers like the Flash's speed would be crucial in the final battle against this evil.
A Kryptonian in the Dragon Ball Z universe could potentially be a very powerful addition. Their natural abilities like super strength, flight, and heat vision could make them a force to be reckoned with. However, they would also face challenges as the Dragon Ball Z world has its own power scale with ki-based powers. They might have to adapt to the different fighting styles and power sources. Maybe they could learn to use ki in addition to their Kryptonian powers, or they could find a way to combine the two in unique ways.
One great Bardock in Dragon Ball Z fanfiction is often depicted as a fearless and noble Saiyan. He is shown as a warrior who, despite the cruel nature of the Saiyan race at that time, had a sense of honor. In some fanfictions, he manages to break free from the control of Frieza in more creative ways than in the original story, making his character even more complex and interesting.
Yes, it's quite normal. Fanfiction can offer new and interesting takes on the Dragon Ball Z universe. It allows fans to explore different storylines, character developments, and relationships that might not be explored in the original series. It's a creative way for fans to engage more deeply with the show they love.
