Well, I admit that naruto is borderline xianxia when you researched it clearly. "Pokemon just took the ideas from them" "Dragon Ball Z only took Characters" Unless Every Pokemon original from CN mythology, you can't say that it's heavily influence from CN culture. While there are some from CN mythologies, there are also other pokemon from Differences Mythologies all together. They aren't being influence by the culture but they are only Using the Culture to create the Pokemons. Being Influence and Being Used are Different. If you look up to character and you want to create a similar character to that character, that Doesn't mean you are being influence by the Culture or anything. It's just mean that you Like that character, not by it origin or something, but Because that Character got something you Like, you like the Character itself and not by it origin, you make a similar character. And in this case, Dragon Ball Z did that. They wasn't being influence by the characters, but it's just because they like the characters, so they put it into their stories. Sure, Songoku was based on Sun Wukong, but by not making them Almost the same, but changing Many Songoku Traits to be different from Sun Wukong, it mean that because they liked Sun Wukong character, so they made a smilar one and changed him to be the one they like more, that's Songoku. And if they are being influenced by CN culture, then they would have made the plots for DBZ got many type similar to Journey to the West, like encounter, goals, reasons, etc...but they didn't. So it just mean that, They Only Like The Type Of Character, so they Put those characters, that they changed to be their own, inside their stories. So, taking a character doesn't mean you are being influence by that character culture or something, but it only mean that Just Because You Like that character, so you took it.
