MDC-98T (Martin's Demon Caterpillar of 98 class. The addition of the letter “T” means that it is also adapted to the smelting of titanium) MDC is a hybrid of the essence-mechanism and demon, in fact - a live melting furnace, capable of “digesting” not only different ores but also refractory metals such as molybdenum and tungsten, forming uniform alloys without foreign impurities. Most of the body of MDC is hidden by thermal insulation material (the length of underground and on-ground protection is about 28 meters), the smelter and the spill site is underground. MDCs of all modifications are allergic to osmium The caterpillar makes loading charge independently, eating it. In the world, only 12 MDCs are used, and one of them works for the RIMMO preparing special alloys for rocket- mystical equipment. Due to the complexity of melts, MDG-98T in the institute often suffers from indigestion and heartburn, which is why it is necessary to soothe it with frozen mercury.

……And it's still pretty harmless mecha-demon
