Korvac

Korvac was an intergalactic warlord who led the Chitauri in their conquest. Taking notice of the powerful figures on the planet Earth, including the Avengers, Fantastic Four, and Doctor Strange, Korvac set out to destroy the planet before those heroes had a chance to stop him. The Guardians of the Galaxy, with the help of Nova and Spider-Man, were able to stop his diabolical plan, destroy his flagship, and kill Korvac in the process, putting an end to his reign of terror.[1]
