The 'Artemis' is a guard guinoid patrolling around the outer walls of the fortress. It vaporises approaching unidentified forces from a distance with a plasma cannon on its right shoulder. Its right arm is a large-calibre rifle (live ammunition) and grenade that ejects bullets by electromagnetic guidance (in essence, a railgun), while its left arm is a laser that can be irradiated for long periods of time, and both have shields on their sides to protect them from enemy attacks. The left shoulder is equipped with a generator to compensate for the enormous energy consumption, and a low-gravity device extending from the waist weakens the surrounding gravity, so movement is easy.
