Moonlight

A silhouetted figure stands overlooking a sprawling city at night, then the scene shifts to a city skyline with purple lights, followed by two figures fighting on a rooftop against a full moon, a man in a red suit firing purple energy beams at a glowing purple entity in a snowy street, a close-up of a man's face bathed in purple light, and finally a man lying on the ground in a debris-strewn alley with fires burning around him.
