On the other hand, this is not a universe where you can fire chi-blasts from training in martial arts, nor do gods exist as giant futuristic armor. This is a universe where you get superpowers from lab accidents or meteorite, and giant mecha is really rather redundant since some dick from space is just gonna knock it over with a single punch. Sure, there's a bit of crossover between the fantastical conventions of western and eastern comics, but I think the OP shows pretty clearly that it's more different than it...isn't. Even if DCU Japanese fiction and media progressed in the exact way it did in our real world, the natural and supernatural components that make up the Super Young Team are still gonna have to conform to the...the DNA of the DCU, I guess you would call it, that we all know and love. A Japanese guy is gonna have to go and dunk himself in some radiation like all the white kids are doing if he wants superstrength, instead of training in a dojo. In that sense, Japan's "own metafolk" would in fact conform more to the western comic book archetypes than the ones above, with the exception of certain minute, almost insignificant traits.
Like I said below, though, I personally do find that to be profoundly unsatisfying. "Why can't we have nice things?" "Because this universe doesn't have them." Oh. :(
