Cross and Nightmare

Appearance: Cross has a very recognizable, stylish design: Face and Eyes: He has white pupils (the left one often takes the shape of a target/cross), and there is a long black scar-line on his right cheekbone under his eye. Clothing: He wears a black T-shirt, a white unbuttoned hoodie with black short sleeves. Shorts: Black shorts with white crosses (the letter "X") on the sides. Accessories: A long, fluffy white scarf held up by two crossed belts, and a gold heart-shaped medallion.
Personality: A jokester who can be very serious, often making fun of Nightmare for his height. He often complains about creatures attacking him and is terrified of cows, but can tolerate it for Nightmare's sake. He can hear the voices of spirits, which are divided into two types: young spirits and old spirits. The old spirits helped Cross, while the young spirits often made fun of him.

Appearance: He was a normal skeleton (similar to Underswap Sans, as he and Dream were created from clumps of energy from the Tree of Feelings). Eyes: Glowing lavender or violet pupils. Clothing: A dark purple long-sleeved jacket. It was fastened with a gold belt with the initials "NM". He wore black pants and dark purple boots. Accessory: He wore a gold tiara or headband with a crescent moon on his head. Personality: Kind and caring: Before becoming the Guardian of Negativity, he was one of the most sensitive personalities. He sincerely loved everyone around him and tried to help. Love of nature: He had a strong attachment to flowers (especially roses) and animals. He can scold Cross for his stupid jokes. He adores cows.
