In fanfiction, it often depends on how the author wants to balance things. Some might make Naruto characters learn to use ki to boost their power levels closer to Dragon Ball Z. Others might have Highschool DxD characters gain new forms inspired by Naruto's transformations to be on a more equal footing. The power levels are adjusted to create an interesting story, not always adhering strictly to the original power scales of each series.
Well, in Dragon Ball Z, the power levels are extremely high and can reach planet - busting levels. Naruto's power levels are more focused on ninjutsu and chakra control, which are not as astronomically high but still very effective in their own world. Highschool DxD characters' powers are more about magic and their devil or angel forms. So, it's hard to directly compare them in a simple way.
Goku's power levels in Dragon Ball Z are off the charts. He can destroy planets with his Super Saiyan forms. Natsu, on the other hand, is very powerful in the Fairy Tail universe with his fire - dragon slayer magic, but he's not at a planet - destroying level yet. However, Natsu has a lot of potential for growth and his magic can be very versatile in combat.
Well, in Dragon Ball Z, power levels are measured in a more straightforward numerical way. Goku at his Super Saiyan levels has an extremely high power level. In the Justice League, Superman is one of the most powerful with his super strength, heat vision etc. In a fanfiction, you could say that Goku's Super Saiyan Blue form might be on par with Superman in terms of raw power, but Superman has other abilities like flight and x - ray vision that Goku doesn't. So it's a complex comparison.
In Harry Potter, the power levels are mainly based on magical ability, like how well one can cast spells or create potions. However, in Highschool DxD, power levels are more about physical strength, demonic or angelic powers. In a crossover fanfiction, a powerful wizard like Dumbledore might be on a different scale compared to a high - level Devil in Highschool DxD. Dumbledore's magic is more about wisdom and knowledge - based spells, while a Devil's power could be more brute force and superhuman abilities.
One popular crossover is a story where the characters from Naruto and Highschool DxD team up against a common enemy inspired by Dragon Ball Z villains. They combine their unique powers like Naruto's ninjutsu, the devils' abilities in Highschool DxD, and maybe some ki - based attacks from Dragon Ball Z.
Plot is important too. You could start with a simple premise like a rift in the multiverse that brings the two worlds together. Then build on it with sub - plots such as a tournament where characters from both series compete. This not only allows for exciting battles but also for characters to learn from each other. Also, don't be afraid to add your own twists and turns to keep the readers engaged.
Well, consider Goku at his peak. His power is so immense that he can shake entire universes. In Star Wars, the most powerful Force users can move objects, influence minds, and have great combat skills. But compared to Goku's Super Saiyan Blue or Ultra Instinct forms, they seem relatively weak in terms of pure destructive power. But the Star Wars side has things like starships and advanced weaponry that could potentially level the playing field a bit.
One idea could be to have the characters from Dragon Ball Z attend the school in Highschool DxD. For example, Goku could be a transfer student with his incredible power causing quite a stir among the devils, angels and fallen angels. He might be confused by the different social dynamics and the whole concept of the supernatural school setting.
You can try websites like FanFiction.net or Archive of Our Own. These platforms usually have a wide variety of fanfictions, including ones related to Dragon Ball Z and Highschool DxD. Just use their search functions to look for the specific fanfictions you're interested in.
Another idea is a fusion of the power systems. Maybe in the fanfiction, the Sacred Gears from Highschool DxD could be enhanced by the Dragon Balls. The Dragon Balls' wishes could be used to unlock new forms or powers in the Sacred Gears. This would create a whole new level of power - ups for the characters in Highschool DxD.
In some fanfictions, Devilman's power is on par with the early - stage Dragon Ball Z characters. For example, his physical strength and speed might be similar to Krillin or Yamcha. But as the story progresses, he has to face more powerful foes like the Saiyans. His power is more of a dark, brute - force type compared to the ki - based powers of the Z - fighters.
