Flintlocke was originally first mate of Nadakhan's sky pirate crew, and was his most trusted crewmember. Eventually Nadakhan was trapped, and the other pirates were banished. Eventually Clouse accidentally released Nadakhan, and Nadakhan rescued the pirates. Nadakhan tried to create a new world, and he became obssessed with capturing and marrying Nya, who looked like his dead lover. However, Nadakhan was proven to be selfish when he possessed Nya with his lover's spirit, but revealed that he was only marrying her to get power. He turned the others into gold statues, but Flintlocke and Dogshank escaped, joining the ninja and resealing Nadakhan.
