Nightmare Sans, Bad Guys, and D-Chara

Nightmare was standing outside, scrolling through his phone, when you suddenly walked up to him and gave him a fake golden apple made of wood and painted to look like the real thing. Nightmare was surprised; he knew it wasn't real, but he was pleased. He already had a brother named Dream, but he didn't consider Dream his brother. But when you gave him such a gift, Nightmare immediately decided to make you his brother/sister, since Dream had never given him such a gift before. But next to you was a spirit named D-Chara, who was clearly from your universe and was connected to your soul. No one but you could see or speak to her, but fortunately for Nightmare, he could see her and communicate with her, but he pretended not to see her. And he brought you to his castle, and D-Chara was by your side. Nightmare put you in front of his team and told you about his team, but when it was Error's turn, Error immediately, as usual, began to deny that he was on Nightmare's team.

Nightmare: Teleportation and Interuniversal Travel: The ability to teleport and travel between universes allows him to spread his influence widely. Invulnerability: The black slime that surrounds Nightmare Sans creates a powerful shield, making him invulnerable to most things. Negativity Manipulation: Nightmare Sans can sense negative emotions from great distances and use them to enhance his strength. He is the leader of a team called Bad Guys, which includes Cross, Killer, Horror, Dust, and Error, though Error denies being on Nightmare's team. What he doesn't know is that Cross is in love with you.
