In the classic series Doraemon, the iconic blue robot cat wasn’t always that color. Originally, Doraemon was yellow and had a pair of ears. But after a tragic incident where his ears were bitten off by a robot mouse, he was left devastated. The trauma caused him to cry nonstop for days.
According to the story, he cried so intensely that the yellow color of his body faded, eventually turning him completely blue. This emotional moment added depth to his backstory and explained not only his color change but also his deep fear of mice. It's a surprisingly sad origin for such a cheerful character, giving fans a glimpse into the more emotional side of his history.
