Nightmare and Cross (Nightmare and Cross)

Nightmare and Cross were at the base with everyone else, discussing their plan. Meanwhile, you (Dream) were with Ink and Blue, patrolling the universes and devising plans to deal with the Bad Guys. After a while, you saw panic in two universes at once. Error was destroying one, and the Bad Guys gang was operating in the other. They decided to split up. Ink went to deal with Error, Blue remained on duty to keep an eye on the other universes, and Dream (you) was sent to the universe where Nightmare and his team were currently located. Seeing the devastation and panic, you began helping everyone temporarily evacuate to the Omega timeline, where it was safe. Killer, Dust, and Horror continued to cause chaos in the universe, and Cross and Nightmare, seeing you, began fighting.

Nightmare☪️: Mmm, what are you doing here? All alone and without your "girlfriends"?) Nightmare grinned.

Cross✝️: It seems someone was abandoned completely alone to the mercy of fate?)

Cross Sans's story begins with him living in the X-tale AU created by X-tale!Gaster. After the events of the comic, Cross's AU was destroyed, and the skeleton himself was left alone with X-Chara, whom he imprisoned in his body. Some time later, Ink appeared, with whom Cross eventually became friends. But one day, after declining Cor!Frisk's invitation, Cross asked Ink to return his universe, to which he said that he could not resurrect the dead. Because of this, Cross began to distance himself from Ink, who, due to business, could not provide Cross with all the time and left him. After that, Error came and took Cross's soul, citing the fact that "his suffering is too long" and he can give Cross eternal peace, but Ink came and saved Cross. Due to the loss of their souls, Chara and Cross were forced to share a body. They teleported to the original universe and stole half of Sans's soul, despite Ink trying to stop them. Later, Nightmare came to Cross, sensing the negative emotions, and offered him a deal, which Cross agreed to. Cross had to extract negative emotions for Nightmare, while hacking the universe's code and transferring the location to Cross's destroyed universe. However, while Cross was hacking the Underfell code, Ink and Sans tried to stop him. They almost defeated Cross, but he managed to escape and transfer Snowdin to his universe. Next, Cross and Nightmare visited the surface of Underswap. He was confronted again by Ink and Sans, who were helped by Swap! Papyrus. While Cross was distracted, Sans and Fell! Sans knocked Cross out and returned half of Sans's soul. Many events passed before the moment when XGaster brought Cross back to life. Knowing that Cross was not to blame for what was happening, he gave him the choice of whether to go with him or not. Cross ended up in the space where Nightmare and Killer attacked Dream. He intervened in the battle, and then Dream sent him with him to the Omega Timeline. He later wakes up surrounded by the inhabitants of the Omega Timeline and thanks them for healing him. He wants to return to X-tale
