Black Order

The Black Order is basically The Children Of Thanos. They appear in Avengers: Infinity War, and Avengers: Endgame, but in Endgame, The Black Order are from the past time-traveled from 2014, while gathered with Thanos, and his armies. Their mission is to get the 6 Infinity Stones, and bring it to Thanos to wipe out half of the universe. Their plans are foiled, 4 of them are dead, but Thanos still gets all of the Infinity Stones before The Black Order could.
