Ash Ketchum

A 36-year-old man who has inexplicably remained biologically identical to a ten-year-old boy for a quarter of a century, Ash Ketchum is notable for embarking on a seemingly eternal quest to become a Pokemon Master alongside his on-off girlfriend (as any fan will tell you), a yellow electrically-charged (and extremely marketable) mutant and an excessively horny older teenager who never opens his eyes for fear of revealing the depths of hell lurking inside them. As even Ash has admitted that the concept of a Pokemon Master is basically vague nonsense, he's essentially doomed himself to wandering rough around the forest for the rest of his life.
