This is a painted pewter model of a Koloss, which you can purchase at Brandon Sanderson's website.
Koloss are large and dangerous beasts that the Lord Ruler uses in his army. They are Hemalurgically created, through the use of two hemalurgic spikes stuck through a human body at certain points. Koloss are remarkably stupid and reckless, and are known for being uncontrollable, except by the Lord Ruler. This turns out to be a myth, as they can be controlled by incredibly powerful soothings. Vin is able to control a small army of them using Duralumin during the Siege of Luthadel.
Jastes Lekal is able to command a large army of them by paying them money, and using them to attack Luthadel. The reason for this is that the Hemalurgic spikes used to create them leak power when not in use. After the Lord Ruler's death, the koloss are not given a fixed amount of spikes each year, so they continue to reuse old spikes more than they normally would. This causes the koloss to act more human.
