Andy and Kaia pursue the villain, now equipped with his weapon of destruction, all the way back to Twilight Island. They fight him, but DiZ proves too powerful, and announces that his weapon is permanently linked to Kaia, and the only way it could be destroyed is if Kaia himself was destroyed. Kaia decides to make the ultimate sacrifice, giving up his life in order to take down Diz, destroying his weapon and allowing Andy to finally take out the evil scientist, fufilling the Destiny Blade's purpose, although he lost his best friend along the way.
