Keith Oster

Keith Oster was a sergeant in the United States military and is noted for being patriotic for his country. His patriotism, however, is shrouded with deep violence as his past experiences involves breaking up protest against the Noah Grace administration, where he arrested dozen of dissenters with "necessary force." One such incident have Oster brutally bludgeoned a dissenter named Elden with a irreparable jaw and multiple minor brain damage. Elden was sent to intensive care, but Oster was never reprimanded for his assault as his commanding officer consider the incident as a necessary action against a "clear and present threat to national security." The possible reason for his violence was a way to channel his dominance over individuals he may consider to be weak.

It is suggested that Oster's history of violence was due to being physically abused as a child from his father that caused him to being who he is. Although, the physical abuse from his father may have taken him too far.

Oster was drafted into Project Abraham where he later learns of the project's purpose which greatly distressed him and even cause him to bargain his way out, but only on deaf ears. Oster's psychiatrist, Cassandra Aklin sympathize Oster's dire situation by lying to him that she is the one who chosen him into Project Abraham. This only cause him to simply quell his distress and develop a barren hatred toward Aklin (which he thinks her as uncaring for him) and anyone. Through out the project, Oster cares less about the other subjects. When Oster was next to be injected with the vaccine resistant to the Chimeran virus, he violently refuses to be injected and threaten to kill the doctor who was to inject him. Oster was then forced to be shot and kill in self-defense by a soldier.
