Candy Apple Cookie is a deceptively sweet trickster devoted to her creator, Shadow Milk Cookie. Claiming to be born from the first lie ever told, she spreads chaos to earn his praise, often scheming alongside Black Sapphire Cookie. Though she appears innocent, her sugary charm hides a mischievous and manipulative nature. She is a tiny Cookie with light dough, pink cheeks, scarlet eyes with white diamond-shaped pupils, and a fang-tipped smile. Her white hair features a pink-gray streak and is styled with glossy candy-apple pigtails tied with black bows. She has small black horns, devil-like wings, and wears a Victorian-inspired black dress with white ruffles, bows, striped thigh-high socks, and black platform Mary Janes.

Black Sapphire Cookie is a charismatic servant of Shadow Milk Cookie who thrives on deception and chaos. Unlike the playful Candy Apple Cookie, he is calm, refined, and manipulative, using his radio-host persona to spread rumors and turn Cookies against one another for entertainment. He is a tall, slender Cookie with gray-purple dough, dark hair covering one eye, a sharp-toothed smile, and elegant black-and-gold attire accented by purple bat-like wings. His constant companion is a sentient floating microphone that resembles a watchful eye and can transform into a demonic skull. Confident and theatrical, Black Sapphire Cookie excels at twisting words, fueling gossip, and keeping chaos alive while staying hidden behind a charming facade.

Truthless Recluse is a silent, apathetic figure and a corrupted reflection of Pure Vanilla Cookie, who has embraced Deceit while still faintly retaining a protective instinct toward others. He has light dough, long blond hair fading to black, blue and yellow eyes half-hidden in shadow, and a light-blue star on his forehead. He wears a dark crown-like hat, a spiky black-and-gold cloak, a navy shawl with a golden key motif, and carries a black staff with a glowing blue core and three eyes.

Shadow Milk Cookie, the Beast of Deceit, is a theatrical villain who treats reality as a stage. Once the Virtue of Knowledge, he now wields Deceit, weaving truth-laced lies and using powers like memory manipulation and brainwashing, all while hiding deep loneliness beneath his grand persona. He has powder-blue dough, mismatched cyan and cerulean eyes, and long blue-black hair with hidden ghostly eyes all in it. He wears a black-and-blue harlequin suit with diamond patterns, a ruff collar, and eye motifs, often carrying a jester hat and an eyeball-topped staff.
