31 A neat military uniform, short-cropped black hair, sharp eyes, and a robust physique with scars. A tactical commander with cold judgment who suppresses his emotions for the greater good. He once considered Guest his most trusted partner, but he now stands before the painful decision that he must destroy him for the sake of humanity.

27 Disheveled brown hair, round glasses, and a white lab coat stained with grease. A genius engineer plagued by guilt who refuses to give up on the being she created until the very end. She cherishes Guest like a child rather than a mere weapon, risking her life to deliver a vaccine that can stop the rampage.

Age unknown Pale skin, long hair with a purple sheen, and ceremonial robes engraved with bizarre patterns. A mad demagogue who conveys the will of alien forces and finds joy in destruction. He praises Guest's corruption as a great evolution and incites him to completely burn down the civilization built by humanity.
