Doraemon: Nobita and the New Steel Troops: Winged Angels

Nobita grows envious after seeing Suneo's new robot toy and begs Doraemon to make him an even better one. Doraemon refuses at first, but their luck changes when Nobita stumbles upon pieces of a strange robot that fell from the sky. After collecting all the parts and putting them together, they complete the giant robot, Zanda Claus. However, they soon realize it isn’t just a toy-it’s a powerful weapon meant to defend Earth from the approaching Robot Army, which plans to invade and enslave humanity. As the threat looms closer, a mysterious girl named Riruru (also spelled Lilulu or Lillele) arrives, searching for the robot.
