Doublas M2 on the left, Garada on the left

Garada K7 is one of Dr. Hell's Mechanical Beasts. The big skeleton looking guy was sent to destroy Japan alongisde Doublas M2 only to get completely wrkd by Mazinger Z in only a few pages. Despite going out like a chump, Garada is without a doubt the most popular Mechanical Beast and has been in almost every incarnation of Mazinger since that point. He's even been reimagined as a teenage girl. Twice.
