After foiling another Team Rocket plan, Ash and co. stop off at Astilbe Town. At the battle club, Tepig walks up to its former trainer, a boy named Suwama. He is the previous owner of Ash’s Tepig due to Suwama abandoning Tepig because he belived that it had no talent for battles when it lost to a Deerling. When Ash went to get Tepig, Suwama said that he was glad to give up such a worthless Pokemon, which enraged Ash after he put two and two together. So Ash is challenged to a Double Battle to prove how useless Tepig is. Can Tepig really prove it’s worth?
