Oubliette was raised in a greenhouse to promote rapid brain growth and longevity and was under the care of her father, a deranged man named Doctor Midas. When she was eight, Dr. Midas scarred her face in a duel to "make her stronger". He told her that it was deformed and from this day on she wore a leather mask when she was around other people. She was trained by her father to kill everything that ever tried to live. Over the years she hunted vampires, space monster, and Greek gods.
Mayor Story Arcs
Oubliette and her father listened from an apartment to the report on Noh-Varr from one of the scientists, who was running tests on Noh-Varr. Oubliette tried to identify Noh-Varr's weak points. One day after Noh-Varr had stopped Hexus, Oubliette arrived in a golden car in the alley where Noh-Varr was found by cops. When she told the cops Midas' military code they decided to leave. With her golden gun and a golden bullet Exterminatrix was ready to take out Noh-Varr.
Noh-Varr escaped, but Exterminatrix followed him on her golden motorbike with built-on machine guns into New York's underground system. They fought through one trains and Noh-Varr kicked her off her bike after they left it. Exterminatrix tried to shoot him with her energy gun, but Noh-Varr avoided the shot and escaped again. Exterminatrix informed her father that Noh-Varr was heading his way and then continued to hunt Noh-Varr. She walked up a building with her vibranium soled boots and shoot at the wall beneath Noh-Varr's feet. He fell from the building and took on his way down Exterminatrix with him. While falling she was able to hold onto a flagpole while Noh-Varr fell with the flag into a bus after Exterminatrix shot him. On the ground Noh-Varr ran into a pack of Dr. Midas' agents. Exterminatrix cheered them on when they beat up Noh-Varr. Her father wanted to know if Noh-Varr was looking at her, but Exterminatrix didn't anyone would want to look at her scarred face. She took off her mask, but her father put it back on. Exterminatrix watched her father beat up Noh-Varr even more to learn the location of his cosmic ray engine. Exterminatrix shot Dr. Midas through the hand with her golden bullet before he could rip out the heart of Noh-Varr. She took Noh-Varr and fled with him into the sewer system.
Exterminatrix brought Noh-Varr to his ship, the Marvel and stayed with him while the machines healed him. When Noh-Varr was conscious again she had a heated conversation with him, which ended with both pulling a gun on each other, but no shot was fired. Noh-Varr revealed his past to Exterminatrix, who was impressed by the robotic Helicoptera Rotors. In the end she understood why he acted so hostile after loosing everyone when her father shot down the Marvel. Noh-Varr gained Exterminatrix's trust and she showed him her face. She only had a small scar on her cheek and realized that her father had lied to her for all those years. Meanwhile Midas, his soldiers and SHIELD arrived and the Plex Intelligence revealed that the technology that led them to the ship was in Exterminatrix's mask. She denied being responsible and told Noh-Varr that she was used like everyone by her father. Once again she helped Noh-Varr to escape her father through the sewer system. She contacted Midas to tell him that she knew that she looked normal and that she would soon get him. Midas then sent a Mindless One after his daughter and Noh-Varr, which attacked them.
The Mindless One killed many innocents from a subway before Noh-Varr and Exterminatrix stopped it. Exterminatrix cut off its head with a part of the railway and then returned with Noh-Varr to his ship where they fought Dr. Midas. Exterminatrix used the Mindless One's head to shoot her father through his chest. Another shot seemingly destroyed him (in reality he was transported to the Dark Dimension). Exterminatrix threw up after killing her father. Then SHIELD entered the ship and caught Noh-Varr and the Plex Intelligence. Exterminatrix escaped and began what she called a Cosmic Jihad. She destroyed a Disney World and threatened on TV to ruin the holidays for every child in the world until Noh-Varr was released. The president watched the news with concern and was told that SHIELD had sent hunter-destroyed telepaths after her.
Civil War Damage Report
At some point Exterminatrix was caught and incarcerated at the Raft. Tony Stark listed her on his list of interesting loose ends as an enemy of the Superhero Registration Act. Puppet Master sent mind-controlled Chilean soldiers to the Raft to kidnap Exterminatrix for his collection of women, but they failed.
