Garada K7 has a light purple-colored, humanoid body with a red breastplate that holds six yellow slits on it’s pecs, dark purple joints, a dark purple neck, and a black pelvis. It has a skeletal face, dark blue stripes on it’s head, and twin giant black scythes pointing upward and attached to each side of the head.

An evil scientist, named Dr. Hell, decides that it’s finally time for him to conquer the world along with his half-man/half-woman lieutenant, Baron Ashura. Dr. Hell shows Baron Ashura his secret army of giant robots called Mechanical Beasts and demonstrates that he can control them with his Staff of Bardos. Dr. Hell uses his staff to take control of a skull-face Mechanical Beast, named Garada K7. Garada K7 takes one of it’s scythes attached to its head and prepares to throw it until Dr. Hell commands him to stop, saying that it would rip his underground empire in two. After he also takes control of another Mechanical Beast, Doublas M2, Dr. Hell shows concern over another scientist, Dr. Kabuto, who is the only one who knows about his secret army of Mechanical Beasts.
