"The Super Young Team contains NONE of these established archetypes."
Is this really a problem, though? These character types are, well, fictional. There's no reason they can't also be fictional within DC's superhero universe. If an American vampire series shifted scenes to China, most people wouldn't find anything unusual if the Chinese vampires were depicted as your standard vampires instead of the creepy paper-to-the-forehead Asian variety. Just because one kind of fictional being is being portrayed as real doesn't mean another needs to be as well.
