Character Profile: Anti-Gnosis Humanoid Fighting System #00-00-00-00-1, Development name KP-X

Anti-Gnosis Humanoid Fighting System #00-00-00-00-1, Development name KP-X, commonly known as KOS-MOS, was created as an Anti-Gnosis weapon under the KOS-MOS Project, headed by Shion Uzuki, who worked for Vector Heavy Industrial. An autonomous android, fitted with black-box weapons systems, KOS-MOS was to be deployed to combat the threat of Gnosis, allegedly introduced to the galaxy by scientist and founder of U-TIC Joachim Mizrahi. However, two years prior to T.C. 4781, she suddenly went berserk, which ended-up killing much of the development team - including Shion's fiancé Kevin Winnicot. Still undaunted, Shion continued to perfect KOS-MOS's systems, often participating in virtual reality simulations on her combat systems.

However, while traveling to Second Milta, the Vector Heavy Industrial fleet, led by the Woglinde, fell under attack by Gnosis after the fleet had recovered a Zohar Emulator. It was during the attack that KOS-MOS - who was secretly given new protocols by higher-ups in Vector, activated - and saved Shion from being killed by the touch of a Gnosis. But oddly enough, she began to behave in a different manner than what Shion had originally programmed. KOS-MOS is now charged with protecting Vector personnel, with the greatest priority to Shion, as well as finding out more about the mystery of the Zohar Emulators. She even exhibited an alternate personality - later named Mary Magdalene, which showed a more human personality that the normally cold, logical behavior KOS-MOS normally exhibits.

KOS-MOS's weapons systems, a legacy of Kevin Winnicot, are many and varied, which include multi-sectioned chain guns to plasma cannons. She even has a Hilbert Effect projector - a weapon capable of rendering Gnosis vulnerable - that is more powerful than many ships, including the Kukai Foundation's Durandal. She even features the X-Buster, an attack which can destroy an entire fleet of Gnosis.
