ZMDC Metal Capsul

ZMDC stands for "Zero Metal Defense Capsule" and refers to the impenetrable armor worn by characters from Jiu Gang, DaJoint's self-published comic book about post-apocalyptic Hong Kong. The comic isn't translated into English, but here's a quick synopsis of the story:

In the year 2037, a catastrophic shower of iron-based meteors rains down on the Earth. The meteors effectively destroy all major urban areas, wipe out most of the world population and reduce civilization to basic survival. Years later, some surviving scientists discover a major find inside the enormous crater on what remains of Hong Kong Island- a large meteorite, floating in the air, unaffected by the Earth's gravitational pull. After careful study, the scientists determine that the meteor's anti-gravitational properties were caused by a total realignment of its atomic structure upon atmospheric entry and impact. The scientists quickly name the newly-discovered matter "Zero Metal."

Thirty years later, Hong Kong Island has fully mastered the use of this new technology and has become the unparalleled military power in the region. Renaming the island "Gang Dao", Hong Kong Island declares itself an independent state and develops highly mobilized armor units- ZMDCs- to enforce their sovereignty and security.

Across the remains of Victoria Harbor, Kowloon is angry and fearful. The unorganized civilian population of the Kowloon Peninsula attempts to unify and resist the advancing troops of Gang Dao, a belligerent power with superior military might. Meanwhile, the Lunnies-a mysterious band of moon colonists-turned-pirates- join the battle against Gang Dao while searching for a vast treasure hidden by one of their former compatriots.
