Professor Gennosuke Yumi is a scientist heading the Photon Power Laboratory after the retirement and later death of Dr. Juzo Kabuto. Prof. Yumi once worked under the professor and was inspired by his designs to create his own robot, Aphrodite A. Later with the Aphrodite's destruction Prof. Yumi and other scientists replaced her with Diana A. Both robots were piloted by Prof. Yumi's daughter, Sayaka Yumi.

Personality
Prof. Yumi is a calm and collected individual dedicated to his work as a scientist. The attacks from the Mechanical Beasts have him act as the advisor to the Science Lab's pilots, doing the best he can for the
Prof.Yumi and Koji
pilots. Prof. Yumi can also be rather stubborn and strict with his works, refusing to upgrade Aphrodite A with additional weaponry other than the Oppai Missile System despite his daughter's constant pleas as he designed Aphrodite to be a peaceful machine.
In certain crises such as the government demanding that Prof. Yumi turn over the Photon Power Laboratory after being threatened by the Underground Empire or being held hostage, Prof. Yumi refuses to give in and takes action that would have even included his own death if he was not saved by Koji and the others. When defeat seems inevitable, Dr. Yumi takes drastic sometimes questionable measures. Prof. Yumi was prepared to commit suicide rather than leave the institute like a captain choosing to go down with his ship.
Relationships
Sayaka Yumi
Dr. Yumi has been Sayaka's only parent since her mother has never been seen or mentioned. Dr. Yumi gives Sayaka and her allies advice when in battle, which Sayaka usually listens to. But even though they are close, Dr. Yumi does not always agree with his daughter, at first refusing to let Sayaka fight or make improvements for the Aphrodite A.
Koji Kabuto
With Prof. Kabuto's death, Dr. Yumi filled in the part as a father figure towards Koji and Shiro Kabuto. While Koji does respect Dr. Yumi, his impulsiveness usually causes him not to listen to his advice.
Juzo Kabuto
Once working under Prof. Kabuto as an apprentice, Dr. Yumi had a great respect for the late scientist. With Prof. Kabuto's death, Dr. Yumi took it upon himself to look after his grandchildren and the Mazinger Z.
History
Dr. Yumi witnessed the Mazinger Z's appearance and the robot protecting the Photon Power Laboratory from a couple Mechanical Beasts. As Koji joined the lab with the Mazinger, Dr. Yumi would provide advice to him and Sayaka in battle. During Great Mazinger and Grendizer, Dr. Yumi had very small roles but offered crucial advice during battles.
