He hails from an unimaginable era: the 31st century. Fleeing through the timestream from the pursuing team of futuristic defenders known as the Guardians of the Galaxy, Korvac the Machine Man has established a secret presence on present-day Earth in the self-created persona of the mysterious Michael. Through such an unassuming guise, Korvac contemplates the elements of a universe he thirsts to command. Yet despite the subtlety of Michael's machinations, the world's greatest super-team -- the mighty Avengers -- catches wind of his cosmos-conquering scheme, thus drawing the two titanic forces into inevitable conflict.
