Based at the Iron Claw Castle in the North Pole, Machine Empire Black Magma is a sinister machine empire that worships the Black Solar God. Their ultimate goal is to establish the rule of Mechahumans over the world, replacing human society with a cold, mechanized order.

Black Magma's technology is advanced enough to trigger natural disasters, manipulate global incidents, and create powerful Mechahuman monsters known as Mongers. They specifically target Japan to seize its geothermal energy reserves, which are needed to power their massive arsenal and further their conquest of Earth.

The true, supreme leader of Black Magma, also known as the Black Solar God. Hinted to have ancient ties to Incan and Mayan civilizations, he is treated as a divine figure by the empire and normally communicates with his followers through a sacred idol.

Though rarely seen directly, his influence drives Black Magma's entire campaign. Fuhrer Hell Satan and the empire's commanders act in his name, using the Black Solar God's authority to justify their attempts to remake the world for Mechahuman rule.

Though he appears to be the ruler of Black Magma, Fuhrer Hell Satan is actually a loyal servant of the Omnipotent God. He commands the empire's day-to-day operations from Iron Claw Castle and directs the Monger Army against Sun Vulcan.

Hell Satan uses fear, technology, and religious devotion to maintain control over his subordinates. His authority extends even over Queen Hedrian after her revival, as he is able to shut down her mechanical heart if she acts against Black Magma's will.

The former ruler of the Vader Clan, Queen Hedrian was found frozen at the North Pole and revived by Black Magma as a cyborg with a mechanical heart. Instead of rebuilding the Vader Clan or avenging her fallen followers, she was forced into service as the high priestess of Black Magma.

Her position gives her power and status within the empire, but her loyalty is enforced by Hell Satan's control over her artificial heart. This creates a tense relationship between Hedrian and Black Magma, as she remains proud, ambitious, and resentful despite serving the Omnipotent God.

A key field commander for the empire and one of Black Magma's primary military officers. General Hedrer helps direct field operations, coordinates monster deployments, and serves as part of the command structure enforcing Hell Satan's orders.

As a senior officer, Hedrer represents the organized military side of Black Magma, standing between the empire's divine leadership and its disposable foot soldiers.

A quartet of elite female spies serving Machine Empire Black Magma. Each Zero Girl specializes in infiltration, assassination, combat, and field operations under the command of Hell Satan.

The team originally operated under Zero Girl 01's leadership. After her death, Zero Girls 02, 03, and 04 continued to serve Black Magma, remaining active through the final battle as some of the empire's most persistent human-scale operatives.

The red-suited field commander of the Zero Girls. Armed with throwing knives, she led Black Magma's early field operations and acted as one of Hell Satan's most active agents during the opening phase of the war against Sun Vulcan.

Her death in a cave-in created a major shift in Black Magma's command structure, eventually opening the way for Amazon Killer to assume a more prominent field leadership role.

The black-suited member of the Zero Girls. She utilized cards as her primary weapons, giving her a sharp and deceptive combat style suited for infiltration and quick assassinations.

After Zero Girl 01's death, she remained active alongside Zero Girls 03 and 04, continuing to carry out Black Magma's spy work and field assignments until the empire's final collapse.

The green-suited member of the Zero Girls. She specialized in close-quarters combat and wielded twin swords in battle, making her one of the team's more aggressive direct fighters.

She continued operating after Zero Girl 01's death, assisting Black Magma's later missions and remaining loyal to the empire through its final operations.

The purple-suited member of the Zero Girls. She utilized yo-yos as her signature weapons, giving her a distinctive ranged combat style built around speed, misdirection, and sudden strikes.

Together with Zero Girls 02 and 03, she survived the early leadership changes within Black Magma and continued serving the empire during its final battles against Sun Vulcan.

A Vader field officer from space who took over as field commander after the death of Zero Girl 01. Loyal only to Queen Hedrian, Amazon Killer brought a more ruthless and personal edge to Black Magma's operations.

A master of stealth, combat, and sabotage, she successfully destroyed the original Sun Vulcan base, forcing the team to rebuild and adapt. Her loyalty to Hedrian made her a dangerous wild card within Black Magma, as her devotion was not truly to Hell Satan or the Omnipotent God.

A space pirate and former partner of Amazon Killer known as the "Galactic Invincible Electric Man." Pursued by the Galactic Police, Inazuma Ginga entered the conflict as a powerful outsider with his own ambition and pride.

After being drawn into the internal power struggles of Black Magma, he attempted to challenge Hell Satan and seize influence for himself. His failed rebellion ended with him being thrown into the empire's monster-making process and forcibly transformed into Inazuma Monger.

A specialized series of high-strength spy mechanoids created by Hell Satan for infiltration, assassination, theft, and sabotage. Each model was subjected to brutal combat testing, with only successful survivors branded as Dark Q agents.

Several late-stage models, including the 97th through 100th, were used in high-risk missions against Sun Vulcan and the GWP. Their assignments included infiltrating the Sun Vulcan organization, stealing dangerous materials, assassinating important national figures, and advancing Black Magma's underground fortress plans. After repeated failures, the Dark Q series was eventually discontinued.

The primary android grunts of Black Magma. Identifiable by their black suits and the red Black Magma insignia on their faces, Machinemen serve as the empire's expendable soldiers.

They are deployed in large numbers to support Mongers, guard Black Magma facilities, attack civilians, and overwhelm Sun Vulcan through coordinated group assaults.

Black fighter planes utilized by Machine Empire Black Magma for aerial combat. Marked with the empire's red insignia, these aircraft provide air support during large-scale operations.
