Pokemon Season 14 - Episode 676 – Battling For The Love of Bug-Types!

Ash and the gang head back to Castelia City and meet up with Burgh in the Gym. For the first match, Burgh sends out Dwebble while Ash calls out Tepig. However, the Dwebble is too strong for Tepig and gets knocked out, so Ash replaces Tepig with Sewaddle. Despite Dwebble's strong defenses and speed, Sewaddle defeats Dwebble only to face Burgh's Whirlipede who at first appears too strong for Sewaddle until it evolves into Swadloon. The newly evolved Swadloon defeats Whirlipede, forcing Burgh to call out his last and strongest Pokemon, Leavanny. Elsewhere, Jessie, James, and Meowth receive orders that the mission is over and they change into their original white outfits, and James captures a nearby Yamask. Burgh's Leavanny soon proves to be much too strong for Swadloon who is soon defeated. Satoshi prepares to send out his next pokemon until Oshawatt pops out of its ball, but he decides that Pikachu would be better and calls Oshawatt back. Pikachu battles against Leavanny, even getting trapped by its String Shot attack, but Pikachu manages to defeat Leavanny, winning Ash the Insect Badge.
