Approximately 20 cm (7.9 in) in length, the Stand is indistinguishable from a real bird from afar. Sporting multiple eyes in a spider-like fashion on it head from the center to the left eye-socket, from its right eye-socket grow two tentacle-like earthworms. Its small legs are robotic in appearance.
Despite showing no trace of personality, Night Bird Flying has some sort of autopilot, as it is usually flying around seeking the warmth of other people.
Night Bird Flying has the appearance of a small bird, and consequently doesn't fight directly. However it is fast enough to catch up to a helicopter flying at 250 km/h (160 mph).
Drug Addiction: Night Bird Flying has the ability to track individual souls. Whomever it tracks will gain the symptoms of a fatal drug addiction. The target will remember who they are, but the addiction will render the rest of their memories incomprehensible. It can manipulate its targets with hallucinations, and render them powerless by impairing their intelligence and decision-making capability. The ability only comes into effect if the target is within range. In addition, the degree of the effect is inversely proportional to the distance between the main body and the Stand.
