Goku's power is measured in different forms and levels in his universe. When it comes to Legendary Pokemon, some of them have the ability to control elements like time and space. In a fanfic, Goku in his Super Saiyan Blue form might be able to match the power of a Legendary Pokemon like Palkia, which has power over space. But it also depends on the situation. If Goku is in an environment where his Ki attacks are less effective, like in a dimension where psychic powers are dominant, he might have a harder time against a Legendary Pokemon like Lugia. Overall, it's a complex comparison as their powers are quite different in nature.
One idea could be that Goku arrives in the Pokemon world by some sort of interdimensional rift. He might be confused at first but then start to explore the concept of Pokemon battles. He could use his martial arts skills to train Pokemon in a unique way, like teaching them special combat moves. For example, he could train a Pikachu to use a move similar to his Kamehameha, but in a more Pokemon - friendly version, like an electric blast with a similar charging motion.
In Ash's adventures in legendary Pokemon fanfics, he often has extraordinary encounters. For example, he might form unique bonds with legendary Pokemon that are not part of the main canon. These fanfics can take his story in new and exciting directions, like having him team up with a Mewtwo in a way that defies the normal Pokemon - trainer relationship. It's all about exploring the untapped potential of his character in the context of the amazing world of legendary Pokemon.
Goku's powers are on a completely different level compared to most characters in Highschool DxD. His Saiyan abilities like Super Saiyan transformations give him incredible strength, speed, and energy projection. In contrast, the characters in Highschool DxD mainly rely on magic and their devil or angelic powers which, while powerful, are not on the same scale as Goku's in terms of raw power. For example, Goku could easily defeat most low - level devils with a single punch in his base form.
Goku's powers are on a completely different level. His Super Saiyan forms would make him extremely powerful compared to most Naruto characters. His ability to fly and shoot energy blasts would be like nothing they've ever seen. Even Naruto in his strongest forms might struggle against Goku.
If Goku was a Tuffle, it would completely change his background and perspective. He might have a different set of powers and enemies.
If Goku was a Saiyan in a fanfic, it could explore different aspects of his heritage and potential. Maybe there would be hidden powers or ancestral ties that come into play.
A 'Goku and Videl' fanfic can explore various aspects of their relationship. It might show their friendship evolving into something more. For example, it could depict how they support each other during tough times. Maybe Videl discovers new sides of Goku as they train together, and this deepens their bond.
A Goku Reader Fanfic is a type of fan - made story. It often involves the character Goku from the Dragon Ball series. In these fanfics, the reader can be inserted into the story in various ways, like being a new character interacting with Goku, or having a special relationship with him. It's a creative way for fans to explore different scenarios and relationships within the Dragon Ball universe.
One interesting crossover could be a battle between Goku and a powerful Pokemon like Mewtwo. Goku's martial arts skills against Mewtwo's psychic powers would make for an epic showdown. Another could be Goku training with Pokemon to increase his speed and agility. For example, he might train with Pikachu to learn quick dodging techniques.
Often, in 'Goku Harem Fanfic', Goku becomes more aware of his romantic side. He might be a bit more in tune with the emotions of the female characters around him compared to his original portrayal in the Dragon Ball series, where he was mostly focused on fighting and training.
