Corvus on Board
As one of Thanos’ trusted killing machines, Corvus was most likely spotted by the Mad Titan himself in the midst of chaos and death, while half his planet was being destroyed. Captured and “adopted” at a young age, Corvus would then come to serve at the behest of Thanos in his quest to capture and wield all six Infinity Stones.
Corvus’ Capabilities
Though Corvus may prefer to sneak up from behind his foes to end the fight quickly and decisively, he can still hold his own with the likes of Vision, Scarlet Witch, and Captain America. Corvus is quick enough to keep up with heroes who can fly at fast speeds and is strong enough to overpower (and almost kill) Captain America.
It is Corvus’ mysterious weapon, a staff with a large curved blade at the end, that he uses to deal the most damage. It can absorb and block energy attacks as well as penetrate vibranium—which Corvus does when he stabs Vision, twice, in the chest. Though neither blow kills Vision, the subsequent wound severely incapacitates the living android, taking away his ability to phase or recover easily.
Corvus’ staff is also strong enough to be used as a method of ripping the Mind Stone off of Vision’s forehead. Corvus never succeeds in his attempt due to interruptions, but it is clear he believes his weapon can do the job.
