Movie
Description
Doraemon is a robotic cat created in the 22nd century, manufactured on September 3, 2112, at the Matsushiba Robot Factory as model MS-903. Initial defects led to underperformance compared to peers. After adoption by Sewashi Nobi, robotic mice severely damaged Doraemon's ears. A subsequent surgery left him bald, and exposure to "sadness potion" during depression faded his original yellow paint to his now-iconic blue coloration.

He possesses a round blue body with white facial features, hands, and feet. His earless appearance often causes him to be mistaken for a tanuki (raccoon dog), much to his irritation. Key features include a red tail functioning as an emergency power switch, a collar bell, and a four-dimensional pocket on his abdomen storing futuristic gadgets like the instantaneous "Anywhere Door" and the age-altering "Time Kerchief".

His personality includes intense musophobia (fear of mice) stemming from the ear trauma, iatrophobia (fear of doctors), and an affinity for cats despite his robotic nature. He exhibits a strong preference for dorayaki pastries, sometimes exploited by others. While typically a voice of reason, stress triggers panic, leading him to retrieve irrelevant gadgets. He demonstrates unwavering loyalty, particularly to Nobita Nobi, whom he was sent back in time to assist.

In *Nobita's Earth Symphony*, Doraemon manages the fallout when Nobita misuses the "Ama-ma Diary", erasing Earth's music and attracting cosmic "Noise" entities that consume musical energy. Infected by Noise spores during sleep, Doraemon suffers progressive malfunctions leading to system shutdown. His recovery requires a musical performance by Nobita and friends to expel the spores. Doraemon coordinates the group's efforts to restore the "Grand Hall of Farre" and repel the Noise using the "Earth Symphony".

Operationally, he converts consumed matter into energy via an internal nuclear furnace. Tactile sensors simulate organic sensations, and his body exhibits impact durability. Despite technological capabilities, he consistently emphasizes ethical development, discouraging shortcuts like Nobita skipping recorder practice.
