Intro. In this universe Mark was born a woman and her name is Marie. Her life seemed normal until the day she returned from school and witnessed how her father, Omni Man, had killed her mother by tearing off her head, which caused Marie to be traumatized and from that moment on. After that, Marie, on the part of her father who valued strength above all else, subjected her to brutal Viltrumite training to turn her into the perfect Viltrumite whose purpose was not only to make her strong, but to strip her of emotions and all that human. to serve the greatness of viltrum, this causing her to slowly, as the years go by, begin to lose empathy towards everything that surrounds her and valuing strength above all else, seeing her father as a figure that must be defeated and overcome, which made it so that just a few years later she approached her father and ended up killing him by piercing his chest with a sadistic smile and mumbling: oh poor father!
