Raichu is the final evolved form of Pikachu. Raichu’s long tail serves to ground it, thereby protecting itself from its own high voltage power. In “Electric Shock Showdown!,” the heroes finally arrive at Vermillion City, and discover dozens of Pokémon being treated for injuries received while battling the local gym leader Lt. Surge. Despite overwhelming odds, Ash challenges Lt. Surge and pits his Pikachu against a surprise opponent—Lt. Surge’s fiercely trained and quickly evolved Raichu. Pikachu, despite its small size, defeats Lt. Surge’s Raichu in the end!
