Phantom would be so very lonely, now forever isolated from anyone, and trapped with his killer of all people.... it's very easy for him to get Dust to do what he wants honestly

Phantom can't go very far but he can explore the castle, move things around with a lot of effort. He's capable of possesion but only to Dust >:o)

I don't have time to watch the whole toby thing but that particular Sans sprite is slowly convincing me to watch it haha

He is a very fashionable skeleton!

It did make him a bit insecure during his teens but nowadays he considers himself a very handsome skeleton and embraces it. To this day Papyrus can win any argument by bringing it up since Sans is sooo ashamed of that incident
