Mechademons

Mechademons come from the Dark Matter Handbook. Much of the text here uses or mirrors the text from that setting.

Mechademons are Demons enhanced with sinister technology. Their evil is boundless and chaotic, yet disquietingly familiar, as if they were born from the failings of the Third Dimension. There seems to be some truth to this notion, for as sentient races clawed their way to the stars and surrounded themselves with great machines and forests of steel, Demons changed as well, incoroporating savage mechanistic enhancements into their already corrupt forms. These mechademons are doom incarnate, the fate awaiting the soul of every evil indiviudual who dies among the stars.

Evil Enhanced

Every mechademon is unique, having surgically inserted brutalistic machines into their bodies to upgrade themselves in various ways. Usually, this makes them tougher, more agile, and purpose-built for cruelty. For example, a razor-sharp forearm blade won’t be more useful in combat than a dagger, but it’s lovely for torture.

Indoctrination

It is always better to be killed than to be captured by a cadre of mechademons, for they can do far worse than maim. With little more than bolts, jagged blades, and drops of Infernal blood, mechademons can add their own “improvements” to a humanoid that they capture, replacing body parts with machines and utterly corrupting the subject’s mind. Mechademons revel in the opportunity for torturous indoctrination, even if the resulting foot soldiers are little more than cannon-fodder. The Demons well understand that watching one’s friend turn into a monster is enough to break the will of most any mortal that would resist them.

Demons, Devils, and Archdevils of Progress

Mechademons are, as the name implies, almost always Demons, though some Mechadevils exist (called Mechinfernals), and many of them serve a singular Archdevil called Fran Klime.

Mod Heads?

Any relationship between their cruel tactics and that of the cult of Sons of Adam seem to be entirely coincidental. While some people who are turned into cyborgs by Mechademons have joined the cult, the cult seems to be independently based.
