Ariana sent Gloom to battle Crystal. The latter's Archy fired Flamethrower on Gloom, who endured the attack, and retaliated against Archy. However, Silver sent Rhyperior, and equipped it with the Earth plate, to let out a strong blast to attack Ariana and Gloom. Gloom continued the battle, and attacked Archy, who emitted Flamethrower to counter the attack.
None of Gloom's moves are known.
