Malamar was sent out to battle Clemont and his Pokémon. Malamar used Psycho Cut, along with Crobat's Air Slash. However, Clemont's Chespin fired Pin Missile and Clemont's Bunnelby used Mud Shot, which stopped the attacks. Later, Malamar was eventually defeated with Crobat.
Xerosic used Malamar to take the Zygarde Cells they found into Xerosic's vehicle. Since Ash-Greninja was following them, Malamar used Signal Beam, but missed and was hit by Water Shuriken. Malamar used a Psycho Cut on Greninja, distracting him and allowing it and Xerosic to escape. Later, Xerosic sent Crobat and Malamar to battle Ash and Clemont. Crobat fired Air Slash, but was stopped by Chespin's Pin Missile. Malamar used Signal Beam and Crobat used Wing Attack. Chespin used Vine Whip around Ash-Greninja, who launched him, allowing him to tackle Crobat. Crobat fired another Air Slash, but was countered and defeated by Greninja's Water Shuriken. Seeing he was overwhelmed, Xerosic called Malamar back and jumped off his vehicle.
