The plot summary of "Metal Black" is explained further through supplementary materials. In the year 2042, a companion star of the planet Jupiter appears a few astronomical units away from the planet and propels the asteroids along Jupiter's orbit towards the Earth, creating a wave of meteorites. As Earth struggles to survive, extraterrestrial cybernetic invaders from beyond the distant star use the meteorites as cover to invade with little resistance, intending to plunder Earth for inorganic materials needed to sustain their forms. Both the aliens and the star they came from are quickly named 'Nemesis'.
