Burgermon have hamburger shaped heads and sometimes a neckerchief. They have blue eyes and a pink dot on each of their cheeks. They have a pure heart and make hamburgers with TorikaraBallmon day and night. They don't wear clothes and are smaller than Burgermon.
The Legendary Warriors encountered Burgermon on the moon serving hamburgers to the Meteormon. They were related to the ones who lived in Hamburger Village. A Burgermon was seen being evacuated from the Autumn Leaf Fair before the Royal Knights invaded it. When Lucemon Chaos Mode destroyed the Ophanimoon, it sent out a shockwave that took out the Cherubimoon and the Seraphimoon where the Burgermon and the other Digimon were destroyed.
