Ultralisks evolved from the docile brontolith; a creature that the ultralisk now bears little resemblance to. The brontoliths' genetic code was dissected, rebuilt and repurposed multiple times. Each phase of the process served to eliminate less desirable traits, as well as augment the creature's ability to withstand severe punishment. This included the creature's superb immune system. As a finishing touch to the ultralisk, the Swarm added the gene that would replace the creature's organs.

When terrans first encountered ultralisks on the battlefield, they observed that the creatures seemed to suffer balance issues, and were easily toppled by artillery fire or loss of limbs. By the Second Great War, "unstoppable" ultralisks had been observed. The additions to their internal structure were revealed, but the data offered very little in the way of finding a counter to the creature. Second Great War ultralisks were also noted to have a greater amount of Kaiser blades, as well as a higher amount of carapace armor.
