3. The Real Reason Why Ash Is Always 10
One of the most recurring jokes that are made regarding the beloved Pokemon series is that after more than 10 years the protagonist of the show is still 10 years old. While many shows like The Simpsons decide to retcon the series' story so than it can make sense that the characters are forever young, this theory gives a really decent explanation that doesn't destroy the show. You might remember that in the first episode of the show after Ash starts his Pokemon journey with the left foot he encounters a mysterious Pokemon roaming the skies. That Pokemon is the legendary Ho-Oh. What's so important about it? Here's his Pokedex entry:
Ho-Oh's feathers glow in seven colors depending on the angle at which they are struck by light. These feathers are said to bring happiness to the bearers. This Pokémon is said to live at the foot of a rainbow.
While some may think that the "bring happiness to the bearers" only means that you'll be happy while watching it, the one who wrote this theory claims that whatever is the thing that makes that person happy will become true, and nothing would make Ash happier than becoming the best Pokemon master in the world. And considering that he's a terrible Pokemon master, it may explain why he's still 10 years old, because if he aged like a normal person he would be dead before he becomes a mediocre Pokemon master.
