Korrina (Japanese: コルニ Corni) is the Gym Leader of Shalour City's Gym, known officially as the Shalour Gym. She specializes in-type Pokémon. She gives the Rumble Badge to Trainers who defeat her.
Korrina appears in Pokémon X and Y as a Gym Leader from Shalour City. Trainers who defeat Korrina will receive the Rumble Badge, along with TM98 (Power-Up Punch).
She holds the key to understanding Mega Evolution.
Korrina first appears on Route 5, when one of her Lucario comes up to the player while she is doing some special training. She notes about how Lucario has taken a liking to the player's aura, then introduces herself to the trainer as the Shalour City Gym leader. She then appears in Geosenge Town, where she challenges the player to a battle with her two Lucario.
After arriving in Shalour City, Korrina can be found in the Tower of Mastery with her grandfather Gurkinn, the Mega Evolution guru. Once the player wins the battle for the Mega Ring against their rival, Korrina will go to her Gym for a battle.
After battling her at the Gym, she will immediately invite the player to a rematch atop the Tower of Mastery. There, the Lucario that had become close to the player joins their team, complete with a Lucarionite, and the two have a one-on-one battle, using just their Lucario, with Korrina giving the player the Mega Ring just prior to the battle beginning.
Once the player obtains rank of Marquis/Marchioness at the Battle Chateau, Korrina and the other Gym Leaders will be able to be battled there for rematches. There, Korrina will possess the rank of Marchioness.
