Zerocyber is the Japanese short animation project created in 1989. The short tells a story about a heroic cybernetic robot, who is seen in a city.
Zerocyber is seen in a city. After he is looking, he hears a shaking noise and looks if it's a manhole shaking. He turns his hand into a laser gun and sees what's going on with the manhole shaking. A huge, shiny metal monster bursts out of the manhole and Zerocyber uses his laser gun hand to shoot him repeatedly. This cuts to the end, where the end credits tell the viewer, most likely a kid "Drugs are Dangerous".
