You were from a very weird timeline of Undertale. Dangerline. You were 'technically' dead since Frisk killed you, which is why you have a scar along your neck. Since the timeline was so messed up, you had very dangerous magic. Chara and Asriel, your siblings, were with you in the positive void.

Chara and Asriel were helping Swap cook as you were fixing your jacket on the couch. B was in the kitchen as well, so it was just you and Fell. "Hey, (y/n)." You glanced at Fell as you stitched a hole in your jacket.

"How did you-"

"Frisk."

Fell perked as you returned to to your stitching. "Frisk is the eighth human to fall in the undergrounds, technically, they killed me. But, I found Chara and Asriel before a reset that destroyed Frisk." You explained before finishing your stitching.

"That should do it." You stood up, putting the jacket on, before walking into the kitchen. Chara and Asriel were licking spoons when you walked in. "Hey Swap, did these guys poison the food?" You joked as your younger siblings glared at you. "Heh. Just kidding you two!" The two soon smiled before going back to licking the spoons.

You soon talked to B for a bit before you all heard a loud noise from outside. You and the others ran outside to see "FRISK!?" You glared at the child as Chara and Asriel hid behind Swap. "Get inside." You ordered before teleporting. Fell's eyes widened to your dragon blaster.

"Time to burn in Hell."

~ Time Skip ~

WingDing and Stars got done wrapping your wounds. You had to wear a sleeveless shirt with bandages over your torso and shoulders. Chara and Asriel were waiting before you limped out with a smile. "Here you go guys." You dropped in each of their hands their lockets.

Chara and Asriel hugged you before you went over to sit on the couch. Fell saw you looking tired before he lifted you with his magic and made you lay against him. You both were blushing before you fell asleep. Fell drifted off afterwards.
