Proxima Midnight

"He will pay for his life with yours. Thanos will have that stone." "That's not gonna happen." "You are in Wakanda now. Thanos will have nothing but dust and blood." "We... have blood to spare."

- Proxima Midnight, Steve Rogers and T'Challa

Proxima Midnight was one of Thanos' children and a member of the Black Order. She and her siblings were essential in his mission to find and harness the power of the Infinity Stones. She fought in the Battle of Wakanda, where she was killed by Scarlet Witch.

Becoming a Child of Thanos
Proxima Midnight was an orphan taken in by Thanos after he conquered her race.

Attack on the Statesman
"There are two more stones on Earth. Find them, my children, and bring them to me on Titan." "Father, we will not fail you."

- Thanos and Proxima Midnight

Proxima Midnight was present with the other members of the Black Order when Thanos intercepted the Statesman holding the survivors of Ragnarok, having already acquired the Power Stone by decimating Xandar. She and her brothers stood guard while Thanos demanded that Loki surrender the Tesseract containing the Space Stone. After acquiring the Space Stone, Thanos ordered his children to retrieve two Infinity Stones on Earth, to which Midnight agreed without question. Leaving the grieving Thor to mourn over Loki's lifeless body, Thanos destroyed the ship before departing with his children.

Attack on Vision
"We don't want to kill you. But we will." "You'll never get the chance again."

- Black Widow and Proxima Midnight

Midnight and Corvus Glaive later ambushed Scarlet Witch and Vision in Edinburgh, Scotland. Midnight and Glaive tried to forcefully remove the Mind Stone from Vision's head, but were interrupted by Scarlet Witch. Midnight then engaged in battle with Scarlet Witch, whilst the wounded Vision attempted to fend off Glaive. The Children of Thanos proceeded to corner Scarlet Witch and Vision. However, they were thwarted by the timely arrivals of Captain America, Black Widow and Falcon. Threatened death by Black Widow, Midnight rebuffed her and retreated from the area with the wounded Glaive.

Battle of Wakanda
"She is on the field. Take it."

- Proxima Midnight to Corvus Glaive

Later in Wakanda, Midnight stood with Cull Obsidian, as she began taunting Captain America along with Black Widow and Black Panther that the Vision and the Mind Stone would soon be taken by Thanos. Angered by Black Panther's threats, Midnight dispatched Thanos' army of Outriders. In the ensuing invasion, Midnight watched in shock as Thor entered Wakanda with Groot and Rocket Raccoon. Having noticed Scarlet Witch had joined the battle, Midnight ordered Corvus Glaive to take the Mind Stone from Vision, who was being operated on by Shuri. Midnight then confronted Scarlet Witch herself, preparing to kill her. However, Black Widow and Okoye came to Scarlet Witch's aid.

Final Fight and Death
"He'll die alone. As will you." "She's not alone."

- Proxima Midnight and Black Widow

Despite facing off against both Black Widow and Okoye, Proxima Midnight was able to hold her own and eventually gain the upper hand over both women. However, Scarlet Witch telekinetically threw Midnight into the path of a Thresher, which shredded her under its spinning blades, and splatting spots of her blue blood onto Black Widow.

Personality
Proxima Midnight always kept on showing fierce loyalty towards her adoptive father, Thanos, but alongside this, she also kept showing love, caring and sense of security towards her husband Corvus Glaive, who is also one of her own adoptive brothers, after being concerned about his state moments after he was wounded by Natasha Romanoff.

Proxima Midnight was trained her entire life to become a fierce and highly skilled warrior, repeatedly showing her tremendous warrior nature in battle many times and began developing her own cruel, arrogant, cold, and fierce nature.

When becoming a part from the Black Order, Midnight also developed extreme sadism; showing pure pleasure driven by herself toward the pain of others and of her own enemies. Her arrogance is what brought her great downfall during the great Battle of Wakanda, stating that no matter what, Thanos would obtain the Mind Stone which still shown her loyalty toward her "father".
