Y/n was a hydra experiment, where they integrated a blood lusted creature that came from a mysterious puddle of a blood like substance. They had taken it and injected Y/n with it creating a different voice in her head then her own and an ability to control blood. The voice in her head which craved for the consumption of blood and was always satisfied from the missions they would send Y/n on. Y/n later escaped from hydra, spending the rest of her teenage life as normally as she could. Living in her small apartment and going to school in midtown high.
