The first Double Battle in Pokémon canon took place at the Kumquat Gym. In order to gain the Gym's Badge, challengers must use two of their Pokémon to defeat two of Luana's Pokémon simultaneously. The Gym is located within the luxurious Kumquat Hotel, which is also operated by Luana. The hotel is several stories tall and has a built in battle arena, an artificial hot spring, a tennis court, and exercise rooms for use for both Pokémon and people.
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.
Together with Alakazam, it knows Bonemerang. 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.
