This Mantine is a water-type Pokémon belonging to Marlon.
Marlon sent Mantine to battle Ferrothorn. Ferrothorn attempted to finish the match with Thunderbolt, but due to Jellicent's Cursed Body, it was unable to use the move. Mantine attacked Ferrothorn with Wing Attack and Bullet Seed and defeat it with Psybeam. Cameron sent his Samurott, who dodged Mantine's Bullet Seed. Mantine dived into the pool and repeated the move, but Samurott dodged and hit Mantine with Hydro Cannon. Samurott used Aqua Jet, hitting and pushing Mantine out of the water. Mantine used Bullet Seed, but the attack was blocked by Samurott's Razor Shell, a move which defeated Mantine.
