"I'm a Headhunter. Nothing like the other Spartans, with their bravado and courage. I take the easy way, I kill them because ONI tells me too. I'm a serial killer, just a government-supported one."
Bethany-A204 was a child on Eridanus II that was conscripted into the Spartan-III program after her parents died. Due to exceptional skill, especially in stealth training, she put into the Headhunter program to do Special Ops missions for ONI. She survived to the Post-War Era, and has her own set of Mjolnir armor, serving as one of ONI's assassins. She is currently hunting the Sangheili mercenary Grono 'Yendam.
"You mean I could fight the bad guys who killed my parents?"
―Bethany contemplating the S-III offer.
Born Bethany Lambert, she was an average grading child at her school in Elysium City. Her parents were both government officials of the CAA that did work on Eridanus II. Bethany or "Beth" as she was called, was easily sociable, and had many friends. In 2530, the Covenant attacked, burning down an office building that Beth's parents were in, killing them. Bethany barely escaped, and was an orphan at age seven. After a few months in the orphanage, Beth was approached by a man with an offer: To join the Spartan-III Program and avenge her parents. Beth immediately accepted, and was taken to the planet Onyx.
