Colorful Creative Costumed Crooks: Goldface and Red Panzer

Keith Kenyon was a political dissident and scientist who discovered a sunken gold chest that enabled him to modify its properties to become an elixir which he drank, turning him into the criminal known as Goldface. After his initial defeat at the hands of Earth-One's Green Lantern, Kenyon developed his gold armor along with a modified liquid gold spray gun. Despite an inherent weakness to the color yellow which prohibited Lantern's power ring from affecting, the hero was still able to outmaneuver Goldface once more. Kenyon would return years later to resume his criminal career in Coast City, and resume his war against his foe.

Helmut Streicher was a Nazi scientist tasked with preventing the initial members of Earth-Two's Justice Society from invading an essential German stronghold under his command. Using his robot, the Murder Machine, he was able to subdue Green Lantern, Flash and Batman. Although the trio were soon after freed by fellow mystery men from America, Streicher realized the benefit of incorporating his machine's armor into a uniform, which he himself would later ware.

Kenyon eventually moved to Central City to form a crime syndicate, and made a foe of that city's hero (and Green Lantern's Justice League teammate), the Flash. After two subsequent clashes with the Scarlet Speedster, Kenyon retired from active villainy, and instead became a union leader.

Streicher's further advancements led to his new suit of armor, and as the Red Panzer repeatedly matched wits with Wonder Woman. Red Panzer's personal agenda was to acquire future technologies, and knowledge using his temporal grappling hook, to gain ultimate power. This inadvertently pulled the Wonder Woman of Earth-One back in the 1940's of Earth-Two, where she met her counterpart and the two Amazing Amazons battled Red Panzer. In a later clash, Panzer worked alongside a fellow German scientist in Paula VonGunther, where they attempted to finally achieve their plans of world conquest for their leader. When defeated by Wonder Woman and a new American hero named the Bombardier, Streicher ended his Red Panzer career, and was presumably convicted for war crimes following the conclusion of World War II.
