The most exciting part is seeing the different power sets interact. Like Thor's lightning powers against Vegeta's energy blasts. It would be a show of raw power and strategy.
It would be amazing. Picture Goku teaming up with Iron Man. Goku's raw power combined with Iron Man's high - tech gadgets could make for some epic battles against villains like Thanos or Frieza. They could learn from each other's fighting styles too. Goku might be intrigued by Stark's intelligence and technology, while Iron Man could be in awe of Goku's ability to constantly increase his power level.
One interesting storyline could be Goku teaming up with Iron Man. Goku's raw power and martial arts skills combined with Iron Man's high - tech gadgets would make for an epic battle against a common enemy like Thanos. They could learn from each other's fighting styles and strategies. Another could be Vegeta and Captain America. Vegeta's pride and determination would clash and also blend well with Captain America's leadership and unwavering sense of justice. A third storyline could involve the Z - Fighters helping the X - Men deal with a mutant - hating villain. The Z - Fighters' unique powers would add a new dimension to the X - Men's battles.
A very powerful pairing could be Whis and Odin. Whis is an extremely powerful being in the Dragon Ball Z universe with near - omnipotent powers. Odin is a powerful Asgardian god. Together, they could use their vast knowledge and powers to manipulate time, space, and reality. They could prevent disasters in both the Dragon Ball Z and Marvel universes or deal with threats that are too powerful for any single hero from either universe to handle.
One possible plot could be that Thanos somehow gets his hands on the Dragon Balls. He wishes for the power to snap away half of all life in the universe even more easily. The Z - fighters sense this great imbalance and travel to the Marvel universe to stop him. Goku, being the most powerful Z - fighter, tries to fight Thanos but quickly realizes his strength is different from what he's used to. Vegeta might have to team up with Iron Man to come up with a technological way to counter Thanos' Infinity Stones while Goku trains to reach a new level of Super Saiyan to take on Thanos directly.
It's hard to say for sure, but Goku would be a very strong contender. His ability to keep increasing his power level through training and reaching new forms like Super Saiyan God and Ultra Instinct makes him extremely powerful. However, characters like Franklin Richards in the Marvel universe have reality - warping powers that could also be very hard to defeat. But if Goku were to fully master Ultra Instinct and combine it with the power of the Dragon Balls, he could potentially be the most powerful.
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.
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.
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 possible plot could be that Naruto and his friends are facing a powerful new enemy in their world. However, this enemy has some sort of connection to the Dragon Balls. Goku and Vegeta sense the strange energy from Naruto's world and travel there using Instant Transmission. They then team up with Naruto and the others. Naruto is amazed by Goku's strength and ki abilities, while Goku is intrigued by Naruto's chakra and ninja skills. Together, they combine their powers to defeat the common foe.
