“ The world's finest playwright, poet, director, actor, clown... Everyone's most beloved trickster! ... Shadow Milk Cookie! „
Shadow Milk Cookie (Korean: 쉐도우밀크 쿠키, swedoumilku kuki) is one of the five Beast Cookies of Cookie Run: Kingdom. He first appeared as an NPC in the Secrets of the Silver Kingdom update (v5.0), and he is to be made playable in the Spire of Shadows update (v6.0)[3].
Shadow Milk Cookie wields the power of Deceit, a corrupted side of the Virtue of Knowledge he once held. He was the original owner of 
Pure Vanilla Cookie's Soul Jam, being stripped of it upon his descent into villainy.
Description (4th Anniversary Site)
Eons ago, there was a being who yearned to learn all there was to learn: Shadow Milk Cookie. Yet, in his endless quest, the Fount of Knowledge stumbled upon a disturbing fact: others were eager to listen to his words more than they wanted to hear the truth... Thus, the Master of Deceit was born to sow chaos and doubt.
Now, freed of his shackles, Shadow Milk Cookie is preparing his magnum opus: a grandiose show to plunge the world into the dark depths of Deceit...
Appearance
Shadow Milk Cookie is a spindly, average height Cookie with powder blue dough and two differently-colored eyes: one cyan right eye with a black slit pupil and black eyelashes, and one cerulean left eye with a white slit pupil and white eyelashes. His mouth is sapphire blue and sly, having teeth which change between straight and sharp depending on his emotions. About his right eye is a pale blue, claw-shaped marking. He has white locks of hair near his face—two that fall against his forehead and one slicked back—azure curled sidelocks, and glossy, sharp, long hair in a dual-toned shadow and lapis style that resembles the extents of a jester's hat. Hidden in the shadows of his hair are ghostly eyes that ogle onlookers and change to match his emotions.
Shadow Milk Cookie wearing his jester hat
Shadow Milk Cookie wears an obsidian harlequin bodysuit with turquoise diamond appliques. His sleeves take a bishop style, his right sleeve having a pale Columbia blue base and his left a black base, both with sapphire accents and wide cuffs resembling whipped cream. The jester wears a ruff collar from which hang curling coattails with a ghostly blue lining and a black outside. Upon its lining are more gazing eyes. He wears his eye-like Soul Jam of Deceit as a brooch on his collar in the same place that Pure Vanilla Cookie wears his own Soul Jam. Shadow Milk Cookie also holds a jester hat split into black and cobalt halves, having a milk-splash crown about its rim and blueberry-shaped pompoms at its extending tassels. He holds a thin black staff with a blueberry eyeball handle and another milk design at its neck, its eye-like design being a direct reflection of Pure Vanilla Cookie's own orchid staff.
Shadow Milk Cookie's entire body drips upwards in milky strands of ectoplasm. He becomes translucent further down on his body, due either to the fact that he has no corporeal form or due to his inherently phantom-like nature.
Personality
Shadow Milk Cookie was once a heralded champion of all Cookies, baked and empowered by the Witches themselves alongside the other Beasts. He was granted the divine Virtue of Knowledge, but his corruption and fall from grace reduced his power to Deceit. Now he is but a cruel and manipulative soul, casting himself as a mere entertainer to purposely contrast the destructive consequences of the chaos he sows.
Shadow Milk Cookie's very generous depiction of himself
Shadow Milk Cookie is a theatrical villain, changing reality into an illusory counterfeit carnival stage to host his performances. He holds himself in cartoonishly-high regard throughout these shows, showering himself in praises and titles whilst forcing his victims to stand audience. Unlike what his clownish appearance suggests, he is mercilessly conniving and intelligent, presenting outrageous lies interwoven with bits of truth to entice his enemies to play along. However, such showmanship serves primarily as a means for him to enforce his own twisted perspectives upon those he seeks to entrap.
As the antagonistic counterpart to Pure Vanilla Cookie and the original owner of his Soul Jam, Shadow Milk Cookie embodies deception and destruction rather than truth and healing. He sees Pure Vanilla Cookie as the unlawful thief of his power and holds a deep grudge against him, targeting him with taunts and using his half of the power of Knowledge to torment the Ancient Hero. Similarly, he is more than eager to cast bloody anguish upon 
Elder Faerie Cookie and 
White Lily Cookie—the two Cookies standing the most in the way of his return to power—and would enjoy nothing more than to tear them to pieces himself. Shadow Milk Cookie relishes in mocking any and all of his enemies through his shows, especially when such prodding often goads them to do exactly what he wants them to do.
Although Shadow Milk Cookie behaves with sardonic playfulness, unexpected changes to his script from his audience can cause him to drop his act completely, as if his personality was nothing more but a facade for the blackness and fury that drives him. Ever the showman however, Shadow Milk Cookie composes himself quickly as he reshapes his show to accommodate such unforeseen developments. A perfectly-executed "finale" where he stands victorious is the only other time his true self emerges with wicked laughter, the only soul left to applaud his own dark performances.
Trivia
- Shadow Milk Cookie appears to correspond to the Spire of Deceit & Truth/Blue Tower region of Beast-Yeast.
- Shadow Milk Cookie shares many visual similarities with the Blueberry Yogurt Academy, especially through his blue eye motif.
- Like
Pure Vanilla Cookie, Shadow Milk Cookie has heterochromia iridis, in which his two eyes do not share a color. - The "Recruit Adventurers" subpage of the 3rd Anniversary of Cookie Run: Kingdom website, being published on January 5th, 2024 at around 2:00 pm GMT +9, accidentally included far more information on Beast-Yeast and the Faerie Kingdom than was intended. Here, Shadow Milk Cookie, alongside Silverbell Cookie, Mercurial Knight Cookie, Elder Faerie Cookie, and the other Beast Cookies, was revealed. This content was swiftly removed and reinstated on the site's main page about 4 days later with slight changes.
