Demyx is the Melodius Nocturne and number 9 in the organization. He is lazy and would rather spend his days writing music then fighting. He has power over water

In 10 new keys the ever cowardly Demyx used a lesser nobody to force Pikachu without Ash to fight him alone, and did surprisingly well. However when Pikachu was shown to also possess a keyblade, Demyx was taken down with a keyblade powered Volt Tackle. But now he is one of Omnitrix's new neihbours, and is busy writing music and stealing his cereal
