In the IDW continuity, the D'Hoonib Empire - also referred to as the D'Hoonibs - was a civilization conquered by the Utroms. The war began during Earth's prehistoric ages, and continued until the later days of the Utrom Empire, when the D'Hoonib Empire finally surrendered. This was one of only two threats to the Utroms' sovereignty, the other being the Praxoid Alliance.
