KOS-MOS

KOS-MOS is a Rare Blade in Xenoblade Chronicles 2. She can grant tremendous power to her Drivers, Rex, Nia, Zeke or Mòrag, and their allies. KOS-MOS uses the light element, wields an Ether Cannon, and acts as an Attacker in battle. She is known as KOS-MOS Re: in the Japanese version.

KOS-MOS is a guest character based on KOS-MOS from the Xenosaga series. She is an armored android robot combat weapon with an artificial intelligence. Her design is based on the KOS-MOS's Version 1 model from Xenosaga Episode I: Der Wille zur Macht; both the original and redesign are by Kunihiko Tanaka. Her cannons' design resembles the Zohar.
