5000 years ago, Gauma was one of the Kaiju Eugenicists, who brought fortune to a certain country (approximately somewhere in China) through the use of their power to control Kaiju. They were known as "dragon controllers" to the neighboring country. Juuga used to look up to Gauma as well. The princess of their country became interested in the power, but then the Kaiju Eugenicists were betrayed, while also betraying the country themselves. Gauma shifted his loyalty to the princess over his comrades and killed them. He then fell over and seemingly died, gaining the scars on his face in the process. At some point, before or after his death, Gauma received Dynazenon from the princess in the form of a dragon ornament. The princess (also his lover) placed his mummified remains together with other relics before killing herself to join Gauma in the afterlife.
