Handplates: Soul of Endurance

In this AU, King Asgore ordered Gaster to do a daily check-up on the human child that fell to the underground. To his dismay, he had no other choice but to do what the king asked despite how much he hated humans. A day later, Gaster noticed the human child was fooling around with his paperwork in anger. He snatched his work from the human and began lecturing them about not touching his stuff. When Gaster looks at his position that the human 'ruined,' the doctor is shocked to see that some of the equations were wrong, and the human child somehow managed to fix his mistakes. He looked back at the human and realized that this child could be the source of everyone's problems, and he will make sure that this child would be his successor or, better way, to put it, his little puppet. But little does he know that this child's soul is unique, and it fills her with Endurance.
