Dr. Smith is a middle aged man with balding light brown hair, a mustache, and a monocle over his left eye. He wears a red overcoat with a white ascot.
Dr. Smith from his short appearance seems to be well mannered and cooperative, working alongside his old colleague to help upgrade a robot to fight the threat of the Mechanical Beasts. He has a distinct distaste towards Dr. Hell aspirations for world domination.
Dr. Smith is a leading scientist in aeronautics, having helped improve on the original design for the Jet Scrander by fixing the initial flaws and improving upon the designs.
Prof. Yumi traveled to New York to get assistance in completing the Jet Scrander for Mazinger Z to use for flight. Later when the Jet Scrander was nearly completed, a disguised robot was sent by Baron Ashura to destroy the Jet Scrander, but his cover was blown and the Jet Scrander was launched.
