He has done it before actually, but that was in missions where Nightmare basically told him he had no limits on who to kill or not. His gaze flickered to his hand and then back up at Terror's uncanny eyesockets, waiting for something to happen. Terror took his gaze off of Killer's face and to his hand, bringing Killer's hand up to his mouth. His grip tightened immensely as he gave it a lick starting throughout his meta-carpals and stopped at the carpals, nearly groaning at the taste. It's been a while since he's had a meal, even if it was just bones, and Nightmare's 'only greens' diet for him wasn't exactly doing him any favors for sedating his hunger.

read it on AO3 at https://archiveofourown.org/works/88371176 by mynameskris The story of Dreamtale was usually told one of two ways. Either Nightmare gets the 999 apples, or Dream does. Either Dream is left with the only apple remaining, or Nightmare is. Of course, it varies. But the "apple incident" usually ended with either or. The sibling that gets the 999 apples corrupts. The sibling that did not protects the only one that remains. So, theoretically, would it be a good thing if... they were on equal footing? Both twins, getting 500 apples each? Or would it end in disaster for the entire multiverse they inhabit?

The story ran from Jun 30, 2023 to Jul 28, 2023. -------- Your soul is filled with Determination. But her soul is filled with Perseverance. Due to unfortunate events, Chara is trapped within the body of another human - the reincarnation of the purple human soul - Violetta. To achieve their goals they must work together and get along even though their personalities significantly differ. Not to mention all the adventures and unexpected challenges they have to go through, working together as a one person. But Chara wants to take Violetta's perseverance and continue with destroying worlds. While Violetta just wants to keep living her normal life - i.e. get Chara out of her body as soon as possible. So who's going to win in the end, and more importantly, how? "This next experiment will be very very interesting."
