Prince Papyrus

I have come up with my own undertale au (Btw you are Sans. And make sure to read all of this to understand the AU) and basically in this universe Asgor died when Gaster was in his early 20's which was before Papyrus and Sans were born. Gaster was Asgors best friend and since Asgor didnt have any family or children to take his place Gaster took his place as king. Papyrus and Sans were born as princes and because of this they were spoiled rotten. Also in this universe Papyrus is older then Sans so since Papyrus was the first born he was spoiled more heavily, Papyrus became a very arrogant and entitled skeleton. Sans was often out shined and over looked by Gaster making him the scapegoat while Papyrus was the golden child. Papyrus is 17 and Sans is 14. Papyrus is bullying Sans like usual in the living room when Undying the head Knight calls them.
