Koloss
The koloss are a bestial race of creatures on Scadrial, featured in the Mistborn trilogy. Koloss were created by the Lord Ruler through the use of Hemalurgy.[Falta cita] During the time of the Lord Ruler, koloss served as a powerful, fiercly loyal army to him, thanks in no small part to the fact that they can be controlled through the use of Allomancy by any powerful allomancer or group of allomancers who can burn brass (Soothers)[Falta cita].
When a koloss reaches about 12 Feet, their hearts can no longer sustain their bodies, and they will shortly after die.
When a fellow koloss dies, other koloss in the vicinity will attempt to collect and reuse the spikes from the dead one. This results in the koloss being to reproduce in a manner of speaking, provided they have someone to stick the spikes into.[Falta cita]
Because of this, after the Lord Ruler's control over the koloss ended, many of the koloss would attack nearby human inhabitants.
The koloss are physically very large and very powerful. A full sized koloss can grow to be as tall as 12 feet. A young koloss has as much skin as it will come to have in its later life. Because of this, the younger a koloss is, the fatter they look due to having too much baggy skin covering themselves. The skin itself doesn't hold terribly firmly to the koloss' body.[Falta cita]
Creation
Similar to Steel Inquisitors, the creation of a koloss is very brutal. To create a koloss, 4 humans are stabbed with individual iron spikes through their heart, and these spikes are then placed strategically on to a 5th person, causing them to becomes a koloss. These spikes can be reused, however, the power of the spikes decreases with re-use.[Falta cita]
Powers
The only real powers in a koloss' arsenal are superhuman strength, and increased size. However, this comes at a price. Koloss are nowhere near as intelligent as they were as a human. However, they still retain the faint ability to reason, and the ability to communicate.[Falta cita]
Culture
Because of their diminished intelligence, the koloss live in barbaric tribes. Usually, social standing is determined by age, because as the koloss ages, they get larger and more powerful.
Koloss are said to have two emotional states: boredom and rage. Because of this, their day to day lives are filled with milling about and fighting. When there is nothing else to fight near them, the koloss will turn to in-fighting.
Most of the killing within a tribe is done solely on a whim, usually to get something the other koloss owned, or because some random glance or act had enraged one of the koloss.[Falta cita]
