" I am sure if you grew up with Pokemon then you understand the question. Why is Ash Ketchum of Pokemon still 10 years old. Isn’t it a little weird to you. Just a little weird that Pokemon has been out for about 15 years and the creators never bothered to make a series where Ash is grown up you know. It seems to me like Ash has been traveling the entire Pokemon world in just one year. That would be the only explanation as to why Ash has not grown up yet. Being an author my self I know that if it has to do with the story then I would not age my characters."
