She was used by the Gym Inspector Nurse Joy to battle Forrest's Rhyperior. Rhyperior put up a good fight and might have beaten Latias if the Legendary Pokémon had not kept on restoring her energy with Recover. Eventually Latias managed to win the battle, countering Rhyperior's Rock Wrecker with Dragon Pulse, enduring its Megahorns and using Recover, dodging its deadly Horn Drills, and hitting it several times with Steel Wing and Ice Beam until Rhyperior finally succumbed to Latias' superior power. Despite winning the battle, Nurse Joy was impressed by Forrest's skill and made him the official Pewter City Gym Leader.
