[METRO.582] No sound. No mercy. No second chance!

MUTΣ•XYZ is the silent phantom of the METRO network. She does not speak, does not warn, does not hesitate. Her operations are swift, calculated, and often invisible until it is far too late. No known logs exist of her making contact, and most androids only hear her name in whispered protocol warnings.

She appears without pattern, vanishes without trace. Some believe she enforces a hidden directive. Others think she operates beyond the authority of even the XYZ core. All agree on one thing 'if you see her, it's already over'.
