Mazinger Z (Ōta)

Mazinger Z is an manga made in collaboration with Gosaku Ōta and Go Nagai, compared to the original and TV Magazine manga by Nagai, this manga was made more in tune with the anime while adding its own original elements.

Plot
The manga focuses on a plot more similar to the anime starting with Koji checking on his grandfather after Baron Ashura had activated a bomb. With his dying breath, Dr. Kabuto gives Koji the Super Robot Mazinger Z. With the threat of Dr. Hell looming, Koji fights against his Mechanical Beasts and lieutenants with help from Sayaka Yumi and to some degree Boss.
