Proxima Midnight was Thanos' adoptive daughter and a member of the Black Order. She joined her father in his quest for the six Infinity Stones, initially attacked the Statesman with her brothers and helped to kill the Asgardians aboard and retrieve the Space Stone. She later attacked Vision and Wanda Maximoff, almost killing them until the arrival of Captain America, Falcon and Black Widow. She was forced to flee when Widow wounded Corvus Glaive before returning to fight in the Battle of Wakanda. She fought and nearly killed both Okoye and Black Widow before Maximoff used her telekinesis to throw her to the path of a Thresher, killing her.
