Most likely Reanimation of Movie 7 Doraemon: Nobita and the Platoon of Iron Men
Nobita envies Suneo's new robot toy and requests Doraemon to construct an even superior one. Refusal is Doraemon's initial response, but Nobita inadvertently comes across mysterious robot pieces that fall from the sky. They collect all the parts and assemble them, resulting in the creation of Zanda Claus, a gigantic robot. Soon, they realize that Zanda Claus is not an ordinary toy but a potent weapon to fight against the impending Robot Army's invasion, destined to enslave the human race on Earth. Suddenly, a mysterious girl named Riruru appears, seeking the robot.
