Love of a Sister and a Demon

by eddsworldgirl21

This a Celestial Au and I threw a bit of MLP lore in it. Just the battle thing. I'm not adding the other things. Dipper becomes sad after a long time without love from his people. So he decides to become evil and destroy Mabel with help from his crush Bill Cipher. He fails and gets banished to the moon. Mabel and Bill become sad about it for a thousand years until Dipper returns.

Mabel was in her room getting ready for bed. Dipper was on the balcony raising the moon for the night to begin. When he was done he goes to check on Mabel. He knocks on the door and waits for an answer. Mabel looks at the door and frowns. She goes to the door and answers it. " Hey bro bro." Mabel said happy to see him. " Hey I came to say good night to you." Dipper said feeling some else around. " Okay." Mabel said while yawning. " Good night Dipper." Mabel said closing the door. She lays down and looks at the picture of her and Dipper as kids. She sighs remembering when Dipper was appreciated and loved by their people. She wanted that back but it won't happen. She looks at the wall and falls asleep for the night.

Dipper sighs while looking at the door to Mabel's room. He wasn't ready to let this plan off. He knew it would hurt Mabel. He goes back to the balcony. He looks down on his kingdom that he and is sister shared. He sighs feeling like no one cared about the light his moon gave off. He looks around and see something shiny and yellow beside him. " Hello Bill." Dipper said turning to him. Bill turns to his human form and smiles. His hair was over his eye so no one can see his other eye. " Hello Dipper." Bill said holding his hand. " So are you sure about this plan?" Dipper asked nervous about it. " It will be okay. You made it." Bill said helping him relax about it. " Okay. Let's go for a walk." Dipper said ready to see what everything looks like for the night. Bill nods and leads him outside.

When they got outside they started walking around. Dipper starts singing while they walked about how he feels unloved by his people. He sang about his plan as well. He started crying while he sang. Bill watched feeling bad for him. He remembers when Dipper was happy. But now it makes him sad seeing the person he fell for in deep sadness. When they were done they went back inside to eat and dance for the rest of the night.

That morning Mabel raised the sun and went to say good night to Dipper. She knocks on the door to his room and waited for an answer. After three minutes she did it again. After another three minutes she went inside and sees Dipper isn't there. She goes to the throne room realizing the sadness and being unloved by their people was too much for him now. She gets there and sees Ford on the floor injured. She looks up and sees Dipper has turned evil after raising the moon after she raised the sun. She sees he looks like a king and his eyes were glowing blue along with smoke coming off his eyes. She clears her throat. " Dipper I don't want to fight you." Mabel said not wanting to fight her twin brother. Dipper looked at her with a glare. " Who's Dipper? I am Mason." Mason said mad at her. They start battling. After a while Mason hits Mabel out of the sky. She falls to the floor and opens her eyes after crashing. She looks at the book beside her and reads the second page beside the first one. She flies up again and uses the spell on him making him fall to the ground. Dipper lays on the ground as Bill tries to keep his soul in his body. It didn't work and Dipper's soul left his body. Mabel saw the whole thing. Her and Bill start crying. Dipper was banished to the moon and wouldn't be back for a thousand years.

A/N: The song Dipper sang is called The moon rise. It's a MLP song and I think the creator of the Animatic is very proud of what she did for it.
