I posted something about this a year or two back -
The Secret History of The Monster Man
The Monster Man once donned the Bullet Helmet circa 2005 - I acquired the helmet after a battle with the original Commander Cody (George Wallace) in the streets of Italy - I threw his broken body off the Leaning Tower of Pisa. He died a short time later and will always be remembered as a worthy enemy.
The Suit itself was retired - destroyed in an epic battle with Kikaider!
