Oleana & Garbodor are being released with an expanded sync grid, as well as the ability to be raised to 6★ EX. Raising the pair to 6★ changes Oleana's outfit to match Rose's own 6★ EX outfit, with a rose burgundy jacket over a black top and tan dress.
Oleana & Garbodor are a Poison-type Tech Sync Pair, with the ability to Gigantamax. Their moves center around inflicting poison and debuffing opponents, with their Passive Skills making it so that any opponent who would be poisoned is instead badly poisoned, and tripling the stat drops of any opponent who is already poisoned or badly poisoned. This means the G-Max Malodor and Venom Drench moves can combine to badly poison all opponents, then reduce their Attack, Sp. Attack, and Speed by a full 6 ranks after the later move is used twice!
