Ash Ketchum and his Pikachu ran into Torterra and battled after meeting Maury, Kai and Allegra. Pikachu used Thunderbolt and the attack wasn't hurting Torterra due to being part ground-type. Torterra used Seed Bomb and Pikachu dodged the attack, attacking Torterra with Iron Tail.
After encountering Darkrai in the city, Torterra used Bullet Seed to attack Darkrai but Torterra was put to sleep quickly after by Darkrai's Dark Void. After waking up, Torterra used its Solar Beam to slow down Alamos Town's disintegration. Torterra was later used once more by Maury, battling Kai and his Empoleon in the Alamos Town Contest but they were defeated by Empoleon's Ice Beam.
