Well, a cool concept for Pokemon and Dragonball Z fanfiction could be that the energy in the Dragonball Z world affects Pokemon in strange ways. For example, Pikachu could learn to use Ki blasts. Also, a story where the Z - fighters visit the Pokemon regions and have to participate in Pokemon battles to save the day. And a more complex idea would be a fusion of the two worlds' power systems. Say, a Pokemon trainer figures out how to use Ki to enhance their Pokemon's abilities, and in turn, the Pokemon help the trainer in combat against the powerful foes in the Dragonball Z world.
In a fanfiction that combines these two universes, it really depends on how the powers are combined. If we consider pure raw power, perhaps a fusion between Goku and a Legendary Pokemon like Dialga would be the most powerful. Dialga can control time, and Goku has his Super Saiyan forms and vast combat experience. But if we look at strategic power, a trainer like Cynthia who has a deep understanding of Pokemon and somehow acquires the ability to use Ki could be extremely dangerous. She could outwit her opponents and use her Pokemon's and her own newfound powers to dominate in battles.
One of the best crossovers could be the combination of power - ups. For example, Naruto's Sage Mode combined with Goku's Super Saiyan form. It would be interesting to see how their powers interact and if they could learn from each other's fighting styles.
Bulma from Dragon Ball Z in Naruto fanfiction has potential. She is smart and resourceful. In the Naruto world, she could use her intelligence to create new technologies or help with strategic planning during battles, and her interactions with the ninja characters would add a new dimension to the story.
There might be a fanfiction that focuses on Vegeta and Bulma's relationship in a more in - depth way. It could show how they handle their differences while also dealing with the Saiyan - Earthling cultural clashes. This type of story can add a lot of depth to their relationship and show sides of the characters that we don't see as much in the official story.
Well, one way the storyline could blend is by having Ruby's unique abilities from her own world interact with the power levels in Dragonball Z. For example, if Ruby has some sort of magic, it could be an interesting contrast to the ki - based powers in Dragonball Z. Maybe she could team up with Goku and his friends to fight a common enemy. Her different fighting style would also add a new dimension to the battles.
Goku could be an interesting main character for such a fanfiction. He already has a lot of charm and is extremely powerful. His naivete in some ways could make it fun as he tries to understand the different female characters from the Naruto universe. For example, he might be confused by Sakura's dual nature of being tough but also having a soft side. Another option could be Naruto himself. He has his own charisma and his never - give - up attitude would attract the female characters from Dragonball Z, like Bulma might be interested in his determination.

It's hard to say. Goku in his Super Saiyan forms has incredible power and can destroy planets. But Naruto has the Nine - Tails' power and Sage Mode. If we consider Naruto at his peak with all the tailed beasts' power combined, he could give Goku a tough fight. However, Goku's ability to constantly increase his power level might give him an edge in the long run.
A Sailor Moon and Dragonball Z crossover fanfiction might start with a strange rift in the universes. Sailor Mercury detects an unusual energy signature that seems to be a mix of magic and ki. As they investigate, they run into Goku who is also curious. The two groups then find out that there's a powerful being trying to merge their worlds for its own evil purposes. The Sailor Guardians and the Z - fighters would then have to put aside their differences in fighting techniques and beliefs to stop this threat. They might have some funny moments like Vegeta getting annoyed with Sailor Mars' sassy attitude or Sailor Venus being in awe of Goku's strength.
