Archduke Gorgon lead this unit when General Angoras failed with Mamergos. He rides on top of it as it faces Great Mazinger in battle. All thrown weapons, such as Atomic Punch and the Great Boomerang, failed as Zerangia merely grabbed them in mid-air. When all other attacks failed against Zerangia, Tetsuya only had his Mazinger Blade and Thunder Break. Handless, Great quickly kick his own blade that pierces right through the warrior beast. With Zerangia distracted, Great Mazinger perform his Thunder Break that fried both Gorgon and Zerangia ending both their lives.
