Tad is a character of the day who appeared in Charizard Chills (EP107). Prior to Charizard Chills, Tad had competed against Trovita Island Gym Leader Rudy and won his hometown's most powerful Pokémon competition. Ash and his friends met Tad after he almost ran them over with his boat, causing Misty to yell at him. Tad apologized and instantly recognized Ash, following Rudy's comments on his strength. At Tad's request, he and Ash competed in a two-on-two battle. Tad sent out his Poliwrath, and managed to defeat both Ash's Pikachu and Charizard, the latter instance being only because Charizard refused to listen to Ash. He then told Ash that he would accept a rematch with him when he learned how to train his Charizard. The next day, Pikachu was captured by Team Rocket. With Charizard now trusting him after the lengths he had gone to while trying to help him, Ash successfully rescued Pikachu. Tad, seeing what had happened, asked Ash if he was ready for the rematch. Ash accepted, and was able to defeat Poliwrath with Charizard, who knocked Poliwrath off its feet and subsequently used Seismic Toss on it. He made a cameo appearance in a flashback in The Fires of a Red-Hot Reunion! (BW116). (Source: Bulbapedia)
