Ash sees Ho-Oh in the first episode of the anime, years before it appears in Gold/Silver. In the first episode of the Pokémon anime, Ash is having a tough time on his way to becoming a trainer, such as constantly being shocked by a disobedient Pikachu. What gives him inspiration to keep going? Spotting a then-unidentified legendary Pokémon that wouldn’t be introduced into the series officially for a couple more years. Though kept vague at the time, in later episodes it was revealed the bird was the Generation II Legendary, Ho-Oh.
