Pixies

A young boy stands with arms outstretched before a large window, looking out over a city at night as a massive, translucent humanoid figure looms behind him, its form shifting and dissolving into the stormy sky. The scene cuts to a bomb falling from an aircraft, followed by a massive nuclear explosion over a city, then a violent storm with trees being uprooted, and finally a distorted, glitching image of a landscape.
