Doraemon is a robotic cat from the 22nd century, manufactured on September 3, 2112, at the Matsushiba Robot Factory. Originally yellow, he turned blue following emotional trauma when a robotic mouse damaged his ears, leaving him with a lasting phobia of mice. He accesses futuristic gadgets and tools through a fourth-dimensional pocket, though his tendency to panic in emergencies can make retrieving the right device difficult. Sent back in time by Sewashi Nobi to improve Nobita Nobi's life and alter the family's future, Doraemon provides guidance and technological assistance. He frequently shows exasperation at Nobita's laziness and gadget misuse, yet demonstrates unwavering loyalty, functioning as a de facto family member in the Nobi household, requiring food and sleep like a human. His personality blends intelligence with anxiety. He maintains friendships beyond Nobita, including an unrequited affection for a cat named Mii-chan. In "A Grandmother's Recollections," Doraemon uses a time machine to help Nobita revisit the past and interact with his deceased grandmother and his three-year-old self. Doraemon manages logistical challenges, like avoiding recognition by Nobita's younger mother, while supporting Nobita's reconciliation with grief. This highlights his role in enabling connections across time, consistent with his function as a caregiver and emotional anchor. Doraemon's core characteristics include technological resourcefulness, emotional patience, and occasional comedic fallibility. His design features a bell, suction-cup hands, and a lack of ears, which are sometimes mistakenly identified as raccoon-dog traits, causing him frustration. These elements define him as a compassionate yet flawed robotic companion dedicated to altering Nobita's destiny through practical aid and emotional support.
