They are not "practically the same". At all. Red, you know, actually has the ability to disband an entire organization, beat the Elite Four, become champion, then become the strongest trainer in the series. Ash gets to the Pokemon League, loses, then moves to a new continent. With Team Rocket still following him. But this isn't about the misconception that Red and Ash are the same person. This is about the Koopalings not having personality.
