Sasha - Injustice 2: Arcade Ending: Red Hood

A young woman living in Gotham City in the aftermath of the Brainiac invasion, Sasha was captured by the costumed criminal Professor Pyg, who wanted to turn her into one of his loyal Dollotron soldiers. 

Although he brutally disfigured her face, she managed to escape before the process could be completed, retaining her cognitive functioning and free will. 

Deemed a failure, Pyg tried to murder her with a meat cleaver, only to be saved at the last minute by the vigilante Red Hood.
