This is a headcanon!! None of this is true, and solely my own idea!

Shedletsky had finally done it. He had created a being from all the negative emotions. He never felt sad or angry anymore, because this being had taken it away. 1x1x1x1 is what he called it. He cared for it anyways. He thought that it would love him, even after being filled with hatred. And it worked. However, the being had gotten itself some…physical powers. The powers being that they could change their form (aka their gender). 1x could be a male (male is based off the looks of default 1x) or a female (based off the betrayed skin). They could also…separate themself. So, essentially, Shedletsky ended up with two “kids”, a female (who likes playing electric guitar) and a male (older and more stern). Male 1x was just called 1x, but the female version was called 4x. Even if other survivors questioned him, he didn’t think much of it. They were his two ‘kids’ and he loved them. They loved him.
