Henry "Hank" Boyd was a Major in the United States Air Force who was appointed as SG-10s team commander at the recommendation of Colonel Jack O'Neill, who he became close friends with over time. On a personal level, Henry has a wife; Heather, and a daughter; Lucy, who he is close to, and is also deeply religious. Henry and his team went to the planet P3W-451 for standard recon, only for it to be caught in the event horizon of a newly formed black hole, resulting in the team being lost.
