Jak'Chinro
From Valiant Entertainment - The Book Of The Geomancer
Jak'Chinro is the first sentient being to operate the X-O Armor that would become X-O Manowar.
Hereafter
Over three million years ago, long before the rise of Unity, Jak'Chinro, one of the last members of an alien race hunted almost to extinction, found the X-O Medallion while on the run from a group of hunters. Though Jak'Chinro ignored what it was, as he smelled his pursuers closing in on him he devoutly wished that it would somehow help him to survive and, in that instant, the X-O Armor wrapped itself around him like a protective shell. Jak'Chinro spent the following six hundred years liberating his people, and, upon his death, he bequeathed the armor to his heirs.
The armor passed from owner to owner, eventually ending up with a team of Unity scientists who tried to copy and mass-produce it, but while they thought they had succeeded, they only understood a fraction of what the artifact was capable of doing. After a while, they convinced themselves that they had created the artifact.
