Tesserect is an experiment created by a mysterious scientist before Gaster. She is composed of 2 cubes linked to eachother, one being on the inside and one being on the outside. She has 1 face per face, no pun intended. Each face has a different emotion, one being happy, another being sad, another being angry, and another being confused. The other 2 sides do not contain any faces, but instead just a flat surface. She is completely transparent, besides her hands and faces. She has 3 clawed fingers that float beside her.


A mysterious scientist- of whom no one had heard nor seen besides Asgore- was in the habit of creating experiments, for the purpose of destroying humanity. Tesserect was his 8th experiment. The scientist immediately lost Tesserect, as she had already no-clipped through a wall and left.

After a long time of wandering, she came across a strange gem. She took this gem, and had it hidden away inside of her. The gem, while being worn, gives off a small glow and provides the wearer with extra defense.
