MCU: 16 Things We Learned From 4Chan's Latest Marvel Movies "Leak"
8. Thanos Has A Crew In Infinity War
The Rumour
According to the cast list leaked for Avengers: Infinity War, Thanos won't be a one man army when he comes to collect the Infinity Stones and take over the universe. He will be joined by Corvus, his "vicious right-hand man", Nox, Ican, Proxima and Ebony all of whom are loyal followers of Thanos and all of whom will require prosthetics and mo-cap work.
Response
There were four horsemen of the Apocalypse, so it would make sense that even Thanos would seek strength in numbers.
The names do also correlate to Marvel characters: Corvus Glaive leads Thanos' armies in the comics; Nox is also known as Black Dwarf and Ican is Supergiant, both of whom are key members of Thanos' Black Order; Ebony Maw was a brilliantly clever strategist the same army, and Proxima Midnight is one of the Order's chief warriors.
Together, they form the Black Order - a group of lethal aliens Thanos brings together to help him raise Hell. That they'd appear alongside him in the films makes a lot of sense.
