Sincrodrone Eidymos

Sincro Phase once existed in a different form, known then as Hyper Phase Pheyden. During this segment of his life, he encountered the first known "Lost Sincrodrones", choosing to defend them against the time traveling Queen Kirallius and her followers, who had set out to eliminate the Sincrodrones due to their eventual "future corruption" at the hands of the abstract mechanical entity known as Argenesis, the ruler of the Gendrone Empire in the timeline Kirallius travelled from. In a brutal confrontation, Hyper Phase was able to stop the Kirallius Incursion by allowing himself to embrace the Villser Virus within and transform into Hyper Phase Pheyaos.

As repayment for his help, the Sincrodrones tried to assist Hyper Phase in finding a cure for his Villser Virus infection. Using their ability to mechanically "procreate" new Sincrodrones, they granted Hyper Phase with a Sincrodrone "son" called Eidymos, Echolinking their life forces together. The duo then ventured together in a continued attempt to cure the Villser Virus, building a small team and eventually crossing paths with the advanced race known as the Sincroborg. The Sincroborg also lent their science to Hyper Phase in his mission, teaching him to fuse with their technology and modifying his relic of a Biovessel. He renamed himself Sincro Phase Pheyden in their honor.
