Soft Pink Hearts

(I do not own Undertale or this picture, they belong to their respectful owners. I only own this story and any OC's.)
Waking up as a ghost makes one assume the worst. For example, having died and not being able to pass on. And another way for one to panic about waking up as a ghost is not being able to remember who you were and are.
When she woke up as a light pink ghost, she assumed she died. When another ghost comes in and calls her 'Happstablook', she straight up giggles in shock later turned to crying. After leaving the house, she could no longer deny it.
She has somehow had become Mettaton before he himself became Mettaton, years before even as she found out she is considered a child still. She broke down, not understanding why she is now in this position. She couldn't remember much about herself, but she is sure she fell asleep as a human. It took a while before she finally had a plan of action, as shaky as that plan was.
She is not Mettaton, but she will make his dream come true in her own way. Her company will be different, she will treat people different because her SOUL has a very different core trait.
She is not like Sans, when the time comes she is a wild card. She does not follow a script and that makes her one of the most dangerous Monsters there is to the human child.
Even before the Determined child came, before she took the name Mettaton, she broke so many rules and laws.
"That's cute." The genocidal child blinks at the sudden giggle. "You think I am going to aim for your SOUL?" A head shake. "Honestly it is easier to snap a neck then care for HP. Unlike the others I don't plan on fighting fair if lives are on the line."
The child only had time to gasp before they fell limp, dead from a broken neck.
The next time they come, they are shocked when it happens differently. This robot was not playing by any rules at all. And that scared and excited them beyond all measures.
