Well, it’s good that he's the oldest among the most popular shonen characters.
Still, I don't understand the Japanese mindset why should every shonen MC character should be around the age between 14-16, thinks like a grown up and has the powers of a god. Magically defeats an opponent who's 50 years in age difference. It's bullshit, I don't find it interesting nor appealing, at least the age between 20-24 is acceptable for a MC.
