When Dipper woke up from transforming into a demon, he noticed that it was already dawn. He quickly looked into the mirror to take a good look at himself. Dipper had two wings that were blue and gold in color. His hair was darker with dark blue highlights with two horns curved downwards at the sides of his head. He had dark blue claws and the color seemed to move upwards until it went past a little of the elbow. He had a tail that was blue with a golden end and it looked like it could implale any threat. His feet had razor sharp toenails and had the same coloring going a little bit off the knees. Dipper felt something sharp in his mouth and he saw white pairs of canines that were razor sharp. 

Dipper loved his transformation and waited for Bill to come in and teach him some stuff. While he waited he thought about Mabel. He thought about how she was a total bitch towards him and how she had everyone wrapped around his finger. She made sure he was bullied so that she'll raise among the social ladder in school. How teachers could criticize him for not being like her and why he always told "lies". It never got better for him either because his parents always beat him for not doing this or that for Mabel. Like he was her butler or something!!! He got madder thinking about how his life was made a living hell because of his sister. He wished that she would just disappear and leave him alone. He also hated his grunckles because they were just as bad as Mabel. They belittled him like he didn't matter at all. He started to cut himself due to this fact and had servere depression because of them. He wanted to make them suffer as he did and wanted them to die nice and slow so he can watch the lights in their eyes vanish. 

As Dipper thought all this, Bill started to smirk. His apprentice is about to destroy his greatest enemies. He waited for a bit and walked in and thought that this going to be fun.
