The universes can blend through power - based interactions. For example, the ki energy in Dragon Ball Z could interact with the magic in Frozen. A scenario could be that the Dragon Balls are used to try and fix a magical imbalance in Arendelle caused by some dark magic. The Saiyans' ability to sense energy could also be used to detect hidden magical sources in the Frozen world.
Character relationships can also blend the two universes. Anna could befriend Bulma, and they could exchange their knowledge. Bulma with her technological know - how could help improve Arendelle's infrastructure, while Anna could introduce Bulma to the unique cultural aspects of Arendelle. Also, Gohan could become friends with Elsa, and they could study each other's powers. Gohan, with his academic mind, could try to understand the scientific basis of Elsa's magic, and Elsa could learn from Gohan how to better control her emotions to control her powers.
Well, the Saiyan scouters could be combined with Star Wars' droid technology. For example, droids could be equipped with scouter - like sensors to detect energy levels. This would give the droids an edge in battle and in detecting hidden threats.
They blend the universes by incorporating the power systems. For instance, in some fanfictions, characters might use Devil Fruits while also having the ability to sense and use ki. Also, character interactions play a big role. Luffy's carefree nature might influence Goku's more straightforward approach to life.
They often blend the two universes by having characters cross over. For example, Naruto could end up in the 'Dragon Ball Z' world and start learning about ki and fighting Saiyans. Or a 'Dragon Ball Z' character could visit the Hidden Leaf Village.
One interesting crossover could be Goku meeting Elsa. Goku might be intrigued by Elsa's ice powers and try to spar with her. He could learn a lot about controlling power from Elsa as she has to constantly keep her emotions in check to avoid causing too much ice mayhem, much like how Goku has to control his Saiyan rage.
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.
If characters from different universes in this fanfiction were to interact, it could be really chaotic. For example, a character from a more technologically advanced universe might be completely baffled by the ki - based powers in the Dragon Ball Z universe. They could try to analyze it with their technology, which might annoy the DBZ characters. On the other hand, a DBZ character like Goku might be intrigued by the different fighting styles and abilities of characters from other universes. He would probably want to spar with them right away to test his own strength. Vegeta, being the proud Saiyan he is, might initially be dismissive of characters from other universes but then see them as a challenge to overcome.
It's hard to say, but Goku would be a top contender. His ability to constantly power up and reach new levels of strength like Super Saiyan God and Ultra Instinct is insane. But Ben in his Alien X form from the Omnitrix also has near - omnipotent powers. So it could really go either way depending on how the fanfiction writer sets up the battle conditions.
Well, first you can start by thinking about the characters you want to focus on. Maybe you're a big Goku fan, so you could center your fanfiction around him. Then, consider the plot. It could be a new adventure, like Goku finding a new form in a different universe. Another way is to look at the relationships between characters. For example, how Vegeta and Goku's rivalry could develop in a new way.
It has brought a new wave of fans to the Dragon Ball Z universe. Some people who might not have been interested in the original because of its sometimes slow - paced storytelling found the abridged version more engaging.
It's likely to be Goku. His ability to reach Super Saiyan levels and beyond gives him an insane amount of power. In comparison, even the strongest quirks in My Hero Academia seem relatively weak. Goku's combat experience and his constant pursuit of getting stronger would make him a dominant force in the merged universe.
