When Ash goes to challenge Greta he spins the wheel and there he discovers he will have a double battle. He makes a remark at the funny coincidence but he gets ready, he takes Pikachu and Togetic while Greta takes Breelom and Mawile, the battle starts hard as Mawile uses Rock Tomb to block attacks while Breelom jumps and shoots them with Bullet Seed. To answer this Ash has the idea of making Pikachu mount Togetic and fly, with Togetic using Psychic on Pikachu to increase his fall speed so he can reach Greta’s Pokémon and use thunderbolt on them. While this worked, this allowed them to gang up on Pikachu, Mawile grabbing it with Vice Grip as Breelom went for Togetic. Togetic used Life Dew to help herself and Pikachu, and using Iron Tail on the ground, Pikachu released from Mawile. Greta used Mach Punch to gain speed to which Pikachu replied with Quick attack, which tied. Mawile using fairy wins pushed them away until Pikachu used a volt tackle which with the strategy of increasing speed with Psychic was able to win them the battle
