First Contact caused a political, social, and economical uproar, and riots ensued. It also caused a religious upheaval, with "fundamental" cults terrorizing and even killing those who believed in the new "Terran" religion. Dygo's parents and siblings were especially persecuted, because Dygo was the Vaxxon who initiated the contact. They were eventually slaughtered while Dygo was on a follow-up trip to earth.
Now orphaned and alienated from his race, Dygo has found a home on earth. He lives on the base, along with Joshua Carpenter, while the Star Force team is home and lives on the carrier while in space.
His tactical and mechanical skills are unparalleled by anyone else on the team, and his diplomatic skills are also a valuable asset. However, his greatest strength may be his sense of kinship with the Star Force team itself, especially with Joshua.
