A key member of the Black Order of Thanos was missing in Avengers Infinity War, and thankfully!
Except the original 6 Avengers, there aren't really big world who came out alive from Avengers Infinity War . An unexpected end (or almost) which managed to surprise the spectators and tape them to their seats. Despite a completely dire situation, the Captain America and Iron Man team still managed to turn the situation around and save everyone in Avengers Endgame . An achievement that would probably not have been possible if the Black Order of Thanos had been complete. A major member was indeed missing, the super-villain called Supergiant. His powers ? Read, control, and above all devour minds.
