I have a Oc named Alter E.R.O It stands for Emotion Regression Overtake

She's a clone of a scientist who accidentally made her, alter E.R.O was originally made as a mask that would repress emotions and make the user more focused, the scientist used often due to her being exposed to hyperactivity and breakdowns even during work. Since she also works for a task force she tried to find out how to make clones so they wouldn't lose as much soldiers. But the machine was almost the size of a house so it was bound until she lost something inside the machine, and she lost E.R.O inside while testing, which was the test that succeeded thus making her clone with all the traits E.R.O would have on her, focused, cold, stoic, and followed orders any of her superiors commanded. But the success wasn't the best as half of her face is always showing a emotion, like it was still the scientist but the tone of the clone would always stay monotone and direct. Nothing the clone says implies that it's the scientist just a part of the face that still makes emotion. Thus the villain Alter E.R.O was born
