EK-0 is the first in a line of post-liberation Robotron intelligence drones, engineered not to speak - but to listen. Nicknamed “Echo” for its passive approach to observation, this unit doesn’t transmit unless it must. It absorbs. It records. It waits. Equipped with a central wide-spectrum hyper-optic lens and twin articulated sensor arrays, Echo glides in complete silence, often mistaken for background noise on hostile scans. Its kinetic movement algorithms mimic gravitational drift, making it ideal for close-range ghost surveillance in dense asteroid fields, space hulks, and urban debris zones. “It maps your intent before you’ve made it.” – Federation black ops field notes, redacted
