Luana owns a luxury hotel on Kumquat Island that also doubles as her Gym. Trainers often stay at the Kumquat Hotel to help prepare for the upcoming battle. The actual Gym appears to be the largest in the Orange Archipelago, outside of Pummelo Stadium.
When Ash first met Luana in Pokémon Double Trouble, she mistook him for her son Travis; Ash bears a striking resemblance to Travis, who also has a Pikachu. She misses her son and wishes to care for him again. Luana's maternal side extends to her Pokémon, whom she cares for deeply, treating each one like her own child.
One of Luana's Pokémon, Alakazam is a strong Pokémon that has learned to battle with teamwork alongside Marowak. Having powerful Psychic attacks, it is capable of immobilizing Pokémon. Using a powerful Hyper Beam attack, it can severely damage an opponent. However after being knocked over, the Hyper Beam was its own demise in Luana's battle with Ash.
One of Luana's Pokémon, Marowak was used in Luana's Gym battle against Ash. After being attacked by Charizard's Seismic Toss, it was not fazed. When Hyper Beam tore across the battlefield and hit Marowak, knocking both of Luana's Pokémon out, it gave Ash the victory of the match.
