The koloss mistborn represents one of the most terrifying and fascinating hybrids in the cosmere. This creature is not merely a beast; it is a calculated engine of destruction, born from the brutal experimentation of the Lord Ruler and the desperate survival instincts of skaa.
The Origin of the Koloss
To understand the koloss mistborn, one must first confront the existence of the base creature: the koloss. Originally, koloss were massive, dim-witted humanoids used by the skaa as living weapons during the rebellion. They were large, strong, and nearly impossible to control, driven by a simple instinct to destroy. The Lord Ruler, seeking to maintain his grip on power after the Catacendre, did not simply suppress the skaa; he sought to weaponize their potential for rebellion. He turned his gaze toward the koloss, viewing them not as people, but as a resource to be optimized.
Hemalurgy and the Birth of a Monster
The process of creating a koloss mistborn is less an act of art and more an act of horrific efficiency. It relies entirely on hemalurgy, the brutal practice of using metal spikes to steal and transfer spiritual attributes. A skaa prisoner, likely already marked with the mists as a potential mistborn, would be captured. The Lord Ruler’s forces would then drive a spike of stolen pewter metal—a metal that grants the attribute of physical strength—directly into the victim’s spine. This act does not grant the power of Allomancy in the traditional sense; instead, it forces the spiritual essence of the pewter-user into the recipient. The result is a being that combines the brute, crushing strength of a pewter feruchemical compounder with the explosive, destructive potential of a mistborn.
The Mechanics of Power
The synergy between the koloss physiology and the mistborn abilities is devastating. A standard mistborn can burn metals to enhance their senses, speed, and strength. A koloss mistborn burns the same metals, but the effects are magnified a thousandfold by their already immense mass. When they burn pewter, their strength increases to levels that can shatter stone and bend steel as if it were wet cloth. When they burn atium, their predictive abilities allow them to anticipate the movements of armies, turning them into unstoppable juggernauts on the battlefield. They are capable of tearing apart Shardblades and shattering plate armor with casual ease, making them the ultimate shocktroops.
Behavior and Control
Despite their terrifying power, the koloss mistborn were never truly reliable instruments. The Lord Ruler’s control over them was a constant struggle. These beings possess the fierce independence and volatile emotions of the skaa, amplified by the monstrous strength of the koloss. They were not soldiers in the traditional sense; they were living disasters. A koloss mistborn could be triggered to enter a blind rage, smashing everything in its path, friend and foe alike. This unreliability meant they were often used as a final, terrifying deterrent rather than a front-line force, a weapon of last resort to be unleashed when the empire faced complete annihilation.
The Legacy in the Era of Wax and Wayne
By the time of the events in the Wax and Wayne series, the Lord Ruler is gone, and the world is changing. The koloss populations, once carefully controlled, have begun to breed and spread. They exist in the wild, forming their own crude societies and developing a strange, collective intelligence. The term "koloss mistborn" is less a classification and more a legend, a ghost from the deep past that still shapes the geopolitics of Scadrial. Characters like Steris and the Bands of Mourning are haunted by the knowledge that these creatures exist, a reminder of the brutal lengths to which humanity will go for power.
