Holy. Shit.

A red graffiti tag of a ghost in a prohibition symbol appears on a white wall, then the scene cuts to a close-up of a red and silver proton pack with a glowing fan, followed by a police car with flashing lights driving down a city street at night, then a large green ghost-like creature emerges in a busy city intersection, then a man with glasses and a striped shirt stands in front of a red light, and finally a glowing blue and white ring spins and emits light.
