Doraemon: Nobita and the New Steel Troops: Winged Angels

Nobita grows envious when Suneo gets a new robot toy, so he begs Doraemon to make him an even cooler one. Doraemon says no at first-until Nobita stumbles upon strange robot pieces that fell from the sky. Once they collect and assemble all the parts, they finish building a giant robot named Zanda Claus. But they soon realize it isn’t just a toy-it’s a powerful weapon meant to defend Earth from an incoming Robot Army that plans to conquer humanity. As the invasion draws closer, a mysterious girl named Riruru (also spelled Lilulu or Lillele) appears, searching for the robot.
