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 - 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.
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.
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.
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.
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.
A common theme is the exploration of different power systems. Like how the martial arts in Ranma 1/2 compare to the ki - based powers in Dragon Ball Z.
I think Gohan and Martian Manhunter would make for an interesting duo. Gohan is a brilliant and powerful character who has a lot of potential. Martian Manhunter, with his telepathic abilities and shape - shifting, could teach Gohan new ways to use his powers. And Gohan could show Martian Manhunter the value of pure physical strength. Also, Trunks and Flash would be a cool pair. Trunks' time - traveling and sword - fighting skills combined with Flash's super - speed would create some really exciting action scenes. They could race each other or team up to outrun a powerful enemy.
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.
Well, it could be about Naruto characters learning ki techniques from Dragon Ball Z. For example, Naruto might try to learn how to use the Kamehameha wave. It would be really interesting to see how his chakra system would interact with ki energy.
