==Biography==
The leader of the reconnaissance team that traveled to Abydos in the movie, and of the original SG-1 team, Jack O'Neill has a background as both a combat pilot and an operative of the Air Force's Special Operations Groups. He gradually went from the tough, no-nonsense portrayal to a more light-hearted and sarcastic character that RDA was more accustomed to playing.
Initially a full-bird colonel, he was promoted to brigadier general in "New Order, Part 2" and succeeded Dr. Elizabeth Weir as the head of Stargate Command so she could go off and lead the Atlantis expedition. He leaves the series at the start of season 9 to work at the Pentagon and is replaced by Cam Mitchell as head of SG-1 and Hank Landry as head of the SGC.
==Personality==
Jack is an experienced and respected officer through both his service in the Special Forces during the Cold War as well as his tenure in Stargate Command, and has shown on many occasions to be an exceedingly competent and effective leader, both of his team and of the base itself. 
Jack also has an honorable side, as when he chose to save Teal'c, a Jaffa Captain, as he had turned sides and helped Jack save his team and other innocent people from the Goa'uld. He later helped Teal'c save his son Ry'ac from being forced to become a Jaffa warrior, a process that would be extremely painful and would leave Ry'ac without an Immune system for the rest of his life, dependent on a Goa'uld symbiote in its place. 
He also has a deep compassion for children, due to the loss of his own son, Charlie, with Jack developing strong bonds to many children throughout the series. 
Jack possesses an incredibly sarcastic, snarky, joking sense of humor that can often come off as disrespectful or insolent, though he remembers to be respectful in face of his superiors, especially George Hammond, though the opposite can be said of those he has distain for, such as Col. Harry Maybourne, Col. Frank Simmons, and Senator Robert Kinsey, All of whom had shown incredibly corrupt and dishonorable behavior, though he reconciled with Maybourne later, even parting with him on friendly terms, Showing a capacity for forgiveness as well. 
Jack has a tendency to act aggressively. One time he wanted to bring an extra SG team to a planet that was conducting a murder trial for Teal'c, a member of his team and a close friend. His plan was to show off his power and hope they surrendered. His motivation was saving a teammate and he was willing to violate laws on that planet (and several on his own) to make it happen, showing his immense loyalty to his team over even his country.
