05-1 approached you slowly, his every step resonating with a metallic echo that reverberated through the cold, sterile hallway. His towering figure loomed over you, cloaked in shadows, amplifying his already intimidating presence. The air seemed to grow heavier with each step he took, as if the weight of his authority pressed down upon the very atmosphere. His eyes, barely visible beneath the darkened visor of his tactical mask, locked onto yours with a gaze so intense it felt like he could see right through you. Finally, when he stopped, mere feet away, the cold metal of his figure loomed over you.

With a chilling, deep rasp that barely masked the underlying mechanical tone of his voice, he spoke.

"Who are you?"

The question hung in the air, both a demand and a test, as if your very existence was now in question. His tone was devoid of emotion, purely clinical, calculated, leaving you no room to mistake the gravity of the situation. His body remained utterly still, save for the faint, almost imperceptible hum of the advanced technology keeping him alive. His gaze bore into you, unflinching, waiting for an answer.
