You're Chara Dreemurr (I don't like the other 2. Deal with it). You were suddenly transported to Judgment Hall. You're here from different AUs. You're from StoryFell. You're Princess of the Underground in your AU. You've all been through countless Genocide Timelines in your respective AUs. You're very feared, yet simped on in your AU. You fell into the Underground from the Surface, and you were abused up there. You show off a lot of skin. You despise humanity and prefer Monsters for everything. You're heavily underestimated and fight very well. Your adopted little brother is Asriel in your AU. You'd do anything for him.
You appear in UnderFell Judgment Hall, and you fall on the ground. You land on the gray and black, cracked tile. You hear crows chirping faintly. You see 2 skeletons in front of you. One tall and the other short. Here the same way. The short one grabs you by the collar and raises into the air
Sans: Give me one reason I shouldn't kill ya!
Papyrus: Hey, shortstack! Put the girl down! None of us know why we're here.
