"Indigo League" is where it all began as the first season of the long-running "Pokémon" animated series. Young Ash Ketchum is just beginning his Pokémon training as he reaches his 10th birthday. Things don't go as expected for the youngster, who gets a Pikachu instead of a standard first Pokémon. Winning gym badges is also tougher than Ash thought it would be. He's not alone in his quest for the badges, though, as former gym leaders Brock and Misty are by his side, along with some new friends.
