Manufactured on September 3, 2112, at the Matsushiba Robot Factory as model MS-903, Doraemon suffered an electrical production accident that detached a critical screw, leaving him with substandard capabilities. Originally yellow, he served as caretaker for Sewashi Nobi. Robotic mice gnawed off his ears; a failed surgical repair left him bald. This triggered severe musophobia and profound embarrassment, especially after mockery from Noramyako. Consuming a sorrow-inducing potion, his tears washed away the yellow paint, permanently revealing his current blue coloration. Sewashi later dispatched him to the 20th century to assist Nobita Nobi and alter the family's impoverished future. Doraemon features a spherical head, large eyes, a red nose, six whiskers, and no visible ears. His body is predominantly blue with white hands, feet, and facial area. He wears a red collar with a yellow bell. His tail functions as an emergency power deactivation lever. A four-dimensional pocket on his abdomen stores approximately 1,293–1,963 documented futuristic gadgets, enabling access to tools like the "Anywhere Door" for instantaneous travel or the "Take-Copter" for flight. This pocket remains consistent across all media. His personality blends loyalty with comedic vulnerability. Intense musophobia triggers dramatic overreactions to mice, while iatrophobia causes resistance to robotic checkups. He frequently becomes flustered when mistaken for a raccoon dog. His fondness for dorayaki makes him susceptible to manipulation. Despite being robotic, he forms deep emotional bonds, especially with Nobita, whom he supports unconditionally. His affection for cats—mechanical or organic—sometimes distracts him, as with his unrequited interest in Mii-chan. Doraemon demonstrates resourcefulness in crises but can panic, leading to chaotic gadget misuse. In *Nobita's Little Star Wars 2021*, his protective instincts are prominent. After Nobita discovers the miniature alien president Papi, Doraemon deploys gadgets like the "Small Light" to shrink the group for interaction and shelter. He orchestrates Papi's safety using the "Wallpaper Secret Base" and modifies a toy tank into the combat-ready "Astrotank" against rebel PCIA forces. On Planet Pirika, he collaborates with resistance fighters, infiltrates enemy facilities using the "Stone Hat" for camouflage, and participates in liberating Papi's society from dictatorship, emphasizing loyalty, teamwork, and ethical responsibility. He shares a brotherly dynamic with his younger sister model, Dorami, who occasionally chastises his leniency with Nobita but assists in critical missions. His bond with Nobita evolves from reluctant guardianship to genuine friendship, marked by mutual sacrifices, exemplified when Nobita retrieves Doraemon’s lost bell despite personal clumsiness. He supports Shizuka, Gian, and Suneo, though interactions with Gian and Suneo involve friction due to their bullying of Nobita. Doraemon’s gadgets symbolize technological optimism and cautionary lessons about overreliance. Tools like the "Time Kerchief" or "Translator Jelly" resolve immediate problems but often exacerbate situations through misuse, reflecting themes of responsibility. His design intentionally incorporates flaws—fearfulness, vanity, impulsiveness—humanizing him as a non-idealized helper, aligning with creator Fujiko F. Fujio’s vision of a relatable companion.
