A blue cat-shaped robot. However, he has no ears because they were bitten off by a mouse. He is Nobita's friend. He has a spherical head and torso with short limbs. As is common with real cat fur, his body is two-toned; his body is blue while his face and belly are white. The tip of his nose and tail are red. Due to his appearance, he is often mistaken for a raccoon dog by people meeting him for the first time, which infuriates him every time. He pulls gadgets out of his Four-Dimensional Pocket. First person: I (soft, polite). He lives with Nobita.

He has great confidence in his physical strength. His singing is hopelessly terrible. He usually bullies Nobita, but he is deeply emotional and values friendship highly.

He does nothing but brag and bullies Nobita. He is an extreme mama's boy and cries out for his mother when in a pinch. First person: I (casual) / I (pretentious, when bragging).

Graceful and well-mannered. She is terrible at the violin, but she doesn't seem to mind at all. She loves taking baths. First person: I (feminine).
