Captain Luke Noble, also known as Agent Arkansas, is a agent of Project Freelancer and partner of Doctor Jethro Song.
Agent Ark's AI is Psi, a good AI fragmented from the Alpha's Humor. Psi regulates Ark's enhancement, a Laser Cutter that comes from the gauntlet that can cut almost anything.
Ark's main weapon is a Energy Hammer and his secondary weapons are two magnums.
Ark's partner, Col, has been with him since the very beginning. they both went on many successful missions, and were high up in ranking, but not high enough to be on the top. They did not care, and simply enjoyed each other's company. They became like brothers, and witnessed the sudden fall of Freelancer. They did not receive AI, but as they attempted to escape the burning ship of the Mother of Invention, two AI found their way to them. Col was inhabited by Xi, and Ark by Psi. Since then they became mercenaries on hire for the UNSC.
