Junkman (ジャンクマン) had slabs of metal covered with spikes in place of his hands. His nickname was Chi no Umi Jigoku (血の海地獄, Hell's Bloodbath). He fought Robin Mask during the Five-Story Ring battle within Warsman's body. Although he was powerful enough to shatter Robin's sapphire-made armor, Robin eventually defeated him with the Reverse Tower Bridge.
