Corvus Glaive was a member of Thanos' Black Order alongside his wife Proxima Midnight and his brother Black Dwarf, and served as the right-hand of the Mad Titan. One of his tasks was to force the planets harassed by Thanos to give his master a tribute. When Thanos targeted Earth as the next planet he would raze, Corvus Glaive arrived to the Jean Grey School for Higher Learning, but left after realizing that Thanos' son was not there.
When Thane, Thanos' son, was found in Orollan, the Black Order moved to that location in order for Thanos to murder his son. Corvus Glaive was destroyed by Hyperion when the Avengers arrived to Orollan in order to fight Thanos. Thanos and Proxima Midnight were frozen in an amber construct which left them in a state of living death by Thane, and they remained imprisoned in the Necropolis along Corvus' glaive, which was all that remained of him.
