Ultimate Shadow Milk Cookie

According to the information displayed on its loading screen, "One drop of truth in the glittering ocean of deception completes the crown of chaos and lies... A crown worn by the Master of Deception, Shadow Milk Cookie!"
Shadow Milk Cookie corresponds to the region of the Needle of Deceit and Truth/Blue Tower of the Beastly Yeast.
Shadow Milk Cookie shares many visual similarities with the Blueberry Yogurt Academy, especially due to his blue eyes, which has led to theories that he could be the founder and first headmaster of the academy.
Later, this was confirmed as true through his story "The Dominion of the Beasts".
Like Pure Vanilla Cookie, Shadow Milk Cookie has heterochromia of the iris, which means that her two eyes do not share the same color.
Shadow Milk Cookie is the first Beast Cookie to have two playable Cookie minions assigned (in her case, Candy Apple Cookie and Black Sapphire Cookie) instead of one, as Cloud Haetae Cookie and Nutmeg Tiger Cookie were the only playable followers of Mystic Flour Cookie and Burning Spice Cookie respectively, while Peach Blossom Cookie and Smoked Cheese Cookie (the former released in mid-updates, while the latter became controllable in mid-updates) were not affiliated with them at all (Peach Blossom Cookie was a neutral character and Smoked Cheese Cookie redeemed himself and aligned himself with Golden Cheese Cookie).
Shadow Milk Cookie is the only one of the Five Beasts still alive as of the date of The Kingdom Blooms Again.
It is later revealed that, despite their bodies being torn apart, the souls of the other four Beasts returned to their real bodies sealed within the Silver Seal Tree, as the vessels they previously possessed were baked creations of the Dark Sorceress's Cookie.

Near omniscience: As an ancient Source of Knowledge, Shadow Milk Cookie knows almost everything, but he can overlook certain details, making him vulnerable to being deceived.
Telepathy: Shadow Milk Cookie can speak through Pure Vanilla Cookie's Soul Jam, which originally belonged to him.
Dark Moon Magic: Shadow Milk Cookie can easily use this form of forbidden magic, even accessing the Dark Side of the Moon, an area that is both literal in the sense of being the back side of the moon, where the source of this magic is obtained, and figurative in the sense of being an infinite dimension, like a void.
Reality Manipulation: Shadow Milk Cookie can manipulate his own dimension (the Needle of Deception) at will.
Metamorphosis: Shadow Milk Cookie can alter his own appearance to better suit an environment and go unnoticed, or alter the appearance of others as long as they are in his domain.
Memory Projection: Shadow Milk Cookie can make others experience distorted versions of one's memories, or make them experience their own past, as he did with Pure Vanilla by constantly making her remember memories of her childhood in a more distorted version, or when she experienced Shadow Milk's past as the Source of Knowledge.
Mental Manipulation: Shadow Milk Cookie is able to manipulate and interfere with people's minds, often flooding the victim's mind with intrusive and tempting thoughts.
Multiversal Travel: Shadow Milk Cookie can travel to other timelines after absorbing some of Ultimate Cookie's power to absorb what remained of the other Beast Cookies' Soul Jams (with the exception of Silent Salt, who destroyed his).

Very little is known about the personality of the Source of Knowledge when he was proclaimed Divine Emissary of Knowledge; however, it can easily be assumed that he was extremely intelligent and wise due to his near-omniscience, having created the Blueberry Yogurt Academy and acting as its first headmaster during its early years. In his own "Domination of the Beasts," he proved to be extremely patient, kind, and eager to discuss the principles of Knowledge with his students and followers, despite constantly receiving disappointing and trivial questions that did not promote the growth of the Biscuit or Earthbread race. He still maintained an upright posture, never reacted violently, and answered all questions posed to him with hesitation.

Shadow Milk Cookie was once a celebrated champion of all Cookies, baked and empowered by the Witches, himself created by First Milk Cookie. He was granted the divine Virtue of Knowledge, known as the Fountain/Milk of Knowledge. However, despite his near-omniscience, he saw how Cookies often shunned bitter Truths and preferred to believe in sweet Deceptions. Eventually, he realized that pain and tragedy seemed to befall Cookies regardless of the knowledge he provided. Despising the Witches for abandoning him on his mission, Shadow Milk Cookie cast aside his Virtue and embraced the mantle of Deception, choosing to plunge the world into chaos until the Witches finally returned to answer for all they had done.

Shadow Milk Cookie is a theatrical villain who always demands everyone's attention with his exaggerated style. He boasts about himself with every line, showering himself and his allies with praise and titles, while verbally degrading his targets. However, he speaks knowing that almost no one believes a word he says, which allows him to spout grandiose lies, sprinkled with undeniable truths, before his audience, reveling in the effect his outrageous words have on others. Luring his enemies with fragments of truth, he seeks to corrupt them with poisonous ideas, manipulating his targets for his own ends. If the opportunity arises to push his hapless targets even further from the moral abyss, Shadow Milk Cookie doesn't hesitate to try, even at the expense of his grand schemes.

As the antagonistic counterpart to Pure Vanilla Cookie and the original owner of his Soul Jam, Shadow Milk Cookie embodies deceit and chaos instead of truth and healing. He sees Pure Vanilla Cookie as an illegitimate thief of his power and a naive would-be savior doomed to fall into despair as well.

Milk of Knowledge had the same proportions as now: slender and of average height, with a metallic blue complexion and two eyes of different colors: a golden right eye with a slit-like black pupil and black eyelashes, and a cerulean left eye with a slit-like white pupil and white eyelashes. His mouth is black and always smiles gently, contributing to his casual, half-closed, and calm expression. On his forehead, like a prophet's, rests a claw-shaped, glaucous mark. He sports three strands of hair, two that rest on his face, similar to bangs, and one styled back alongside long, spiky hair that is divided into three sections, whose colors resemble the night sky, changing from shades of dark blue to light blue at the tips, with white sparkles extending throughout his hair, like stars, and side strands that are also the same night sky colors as his hair.

Unlike Shadow Milk's more buffoonish attire, the Fountain of Knowledge wore an oversized black clerical robe with equally oversized black sleeves and dark yellow cuffs. It sported a black ruff collar adorned with gold details that resembled splashes of milk; beside it, a simpler dark yellow collar with sparkling yellow diamond appliqués, from which two large, dark yellow ribbons extended, converging in front of the ruff and collar. On this collar was a gold brooch in the shape of a six-pointed star with a keyhole in the center. It also wielded a golden staff shaped like a key, with its Soul of Knowledge at the center of the upper section, molded into the shape of an eye, and in its other hand, it held a glittering crystal ball. A radiant white crown adorned its head, symbolizing its status as the "master of all there is to know," and finally, the Fountain of Knowledge was surrounded by a golden elliptical halo.

Shadow Milk Cookie is a slender, average-sized cookie with light blue dough and two different colored eyes: a cyan right eye with a slit-black pupil and black eyelashes, and a cerulean left eye with a slit-white pupil and white eyelashes. His mouth is sapphire blue and cunning, with teeth that shift between straight and sharp depending on his emotions. Above his right eye is a pale blue, claw-shaped mark. He has white strands of hair near his face, two falling across his forehead and one side curled sky blue strand swept back, and long, shiny, spiky hair styled in a two-tone shade of shadow and lapis lazuli reminiscent of the tinsel of a jester's hat. Hidden among the shadows of his hair are ghostly eyes that stare at viewers and change with his emotions. That's why he considers himself "extremely handsome." Who knows? He's probably right.

Shadow Milk Cookie wears an obsidian harlequin bodysuit with turquoise diamond appliqués. Its sleeves are bishop-style; the right has a pale Columbia blue base and the left a black base, both with sapphire details and wide cuffs reminiscent of whipped cream. The jester wears a ruff collar from which ruffled skirts hang, lined with ghostly blue and black. Above the lining are more eyes staring at him. He wears his eye-shaped Soul Jam of Deceit brooch at his neck, in the same place where Pure Vanilla Cookie wears hers. Shadow Milk Cookie also holds a jester's hat split into two halves, one black and the other cobalt blue, with a crown that resembles milk splashes on the brim and blueberry pom-poms on the tassels. He holds a thin black cane with a blueberry-shaped eyeball and another milk design at the neck, the eye-shaped design being a direct reflection of Pure Vanilla Cookie's orchid cane.

Shadow Milk Cookie is the main antagonist of Act 1 and Act 2 of the role-playing and strategy game Cookie Run: Kingdom, released in 2021. He is a diabolical jester who wields powerful magic, as spectacular as it is terrifying; a master of chaos, he creates cruel illusions and bends reality to his will with the aim of destroying Earthbread's ideas of what is true or false.

Created long ago as the "Source" of Milk of Knowledge to spread wisdom among the other cookies, this once benevolent emissary of the Witches grew disillusioned over time, losing faith in the absence of his creators and the lack of understanding from the cookies around him. Consequently, he began to spread deliberate falsehoods; thus, driven by a thirst for thrills and resentment toward his creators, the newly christened Shadow Milk Cookie corrupted into a Beast, whose goal now is to transform the world into a chaotic spectacle where reality and illusion are no longer distinguishable.

He is the leader of the Five Beasts, who originally sought to recover Pure Vanilla Cookie's Soul Jam. He wields the Light of Deception, which was originally the Light of Knowledge, before its corruption and transformation into a villain. He is the archenemy and evil counterpart of Pure Vanilla Cookie, who wields the other half of his Soul Jam, the Light of Truth.

After being betrayed by Silent Salt Cookie and nearly crumbling in his hands along with the other Beasts, Shadow Milk Cookie absorbed a fragment of the Ultimate Cookie to survive and absorbed the souls of the other Beasts, except for Silent Salt, who destroyed it. With his newfound powers, Shadow Milk Cookie traveled to the past and split the timeline to create a new world in his own image, but he gradually lost himself among the other Beasts and the Ultimate Cookie that resided within his mind.
