The Dark Avenger
Kat Schuster was an ordinary 21 year old before she was kidnapped and turned into a test subject in the king cobra project, a project run purely by hydra and strays from the Soviet Union. They wanted to create a bigger better black widow, so they kidnapped 15 girls and they trained with a master assassin under the alias of king cobra. They ran series of painful experiments on them using what they had left of the tesseract to make them stronger than any superhero before and it worked, to an extent. Kat could control things with her mind, make people see their worst nightmares, bend matter to her will, and even control the human body. The experiments had done something to Different to every surviving girl but Kat was the clear successor over all the others. They gave her the alias queen cobra because she had defeated her master with her agility and quick silent attacks that were deadly as poison. She had talents and traits that made her the perfect candidate, they molded her into their version of a spy. They overlooked over thing when picking her, she couldn't be controlled. One night she broke from her bindings and she got her revenge. She made them feel the pain she had gone through, and not so sadly, they couldn't handle it. It was a blood bath that night, every life lost was at Kat's hand and she had to admit, she liked it. She had a taste for blood and she wanted more. She vowed she would kill every member of that organization, to make them pay for what they've done. After everything that happened Kat knew she could never go back to the life she had lived before, her dark past would haunt her days and nights.
