Pokemon is gearing up to say goodbye to Ash Ketchum once and for all after 25 years of watching him working his way through the regions, and the newest episode really made sure to highlight a missing piece of the puzzle by taking a shot at Ash's dad in a new anime special! Although Ash has been traveling through the Pokemon world across many different kinds of series in the past 25 years, there are some big aspects of his life that don't really change. Ash never ages, he travels with Pikachu, and his father's always been absent.
