One of Thanos‘ Black Order was notably absent from the Avengers sequel.
After being one of the main antagonists in Avengers: Infinity War, Proxima Midnight didn’t come back for Avengers: Endgame. While the adoptive daughter of Thanos met her grisly end thanks to Scarlet Witch in the third Avengers film, a past-version of the character does appear on-screen in Endgame, if for the briefest moment in the battle sequence, but without any real presence.
