Furnace

Backstory: Furnace's origins are shrouded in mystery, he doesn't exactly know why he was created in the first place. He believes that he was made to either be some sort of artificial super soldier made for the King's personal defense, or to be a replacement for the princess to marry in order to maintain the Royal family line without needing to take in a prince from another family. Whatever the case was, he was abandoned regardless for being too dangerous and unstable to keep around, and the coal needed to fuel him efficiently was simply expensive with little pros. He was tossed out once they waited for the coals inside him to run dry, dropping him into a pool of lava in a cave near the outskirts of the Wretched Woods to keep anyone from reactivating him, but they were unaware that the lava became Furnace's new power source to fuel the living fire inside of him, creating a new semi-solid element named corium since the lava contained trace amounts of the planet's core, making a near limitless power source to keep him sustained. After reawakening, he found his way deeper inside of the cave to find an abandoned mine where large deposits of montan wax and Ozokerite wax were plentiful, and he decided to experiment... and after some time, using a mix of wax and wick made from leftover ropes from lanterns, he created the first new species that would make up his army to eventually exact revenge, and he named it a Wickling. Appearance: Furnace appears as a regular looking knight at first glance, but it's upon closer inspection that you notice his more mechanical structure. Exhaust pipes on his helmet and back constantly billow out smoke, along with many other vents and holes in diamond shapes across the blackened plating making up his body. There is no physical form within the armor, only a living inferno with flames licking outward from his visor and chest hatch where the lava infused coals burn brightly and continuously, leaving no shadows to dwell within his proximity. Weapons/abilities: Furnace is deceptively unarmed, but is able to spew out flames and torrential bursts of scalding hot smoke out from four diamond shaped holes in his right palm. On his right hand is a build in device that uses the heat energy and smoke buildup to create large amounts of pressure within a specialized gauntlet that can then punch forward with bone shattering force using the extendable metal slab with many blunt grooves on it to make it resemble the shape of a meat tenderizer (functioning similar to one as well when used against flesh in battle). Alternatively, Furnace also uses a collapsible chopping axe that is symbolic for the cutting down of old empires to plant a new and better one.
