Introduction to Cookie Run Kingdom Onion Cookie

Onion Cookie is a Rare-grade Support Cookie in Cookie Run: Kingdom, first released on January 21, 2021. She occupies the Middle position in battle and uses she/her pronouns. Despite her timid demeanor, Onion Cookie plays a vital role in aiding her allies with supportive abilities. Though she is considered an Immortal Minor, her presence carries an aura of sadness and mystery. Her internal ID is cookie0058, and her character was designed by Seo Yeokyeong (서여경). She is known by different names across regions, such as 양파맛 쿠키 in Korean, オニオン味クッキー in Japanese, 洋蔥餅乾 in Chinese, and คุกกี้รสหัวหอม in Thai.

Based on an onion, Onion Cookie uncontrollably sheds tears of onion juice, a direct reference to how onions affect the eyes. Ironically, she’s terrified of ghosts—even though she herself is heavily implied to be one. Unaware of her own passing, lore hints suggest she may have died in the “Ghost of the Tower” while hiding during a game of hide-and-seek. Her voice has a subtle reverb effect, enhancing her ghostly undertones. Onion Cookie often expresses her sorrow and fear through tearful quotes like “Where is everybody…?”, “It’s scary here…”, and “I can’t stop crying…”, though she occasionally smiles while watering plants, eating, or holding her beloved doll.

She has a small stature with medium, yellow-toned dough and long, deep purple amaranth hair accented by lilac highlights. Her teary indigo eyes convey her constant sadness. She wears a frilly white nightgown and always carries a unique rabbit-like doll with an onion-shaped head, pale green leafy limbs, and black ovular eyes. She doesn’t remember who gave her this comforting companion, but it never leaves her side.

Her character is brought to life by a diverse cast of voice actors, including Lily Ki (LilyPichu) in English, Jang Mi in Korean, Chujo Tomoyo in Japanese, Xue Qing in Traditional Chinese, Benchuanron Wanitchiophan in Thai, Tanja Dohse in German, Florine ORPHELIN in French, and Ge Zirui in Simplified Chinese.

Onion Cookie’s Skills (Unstoppable Tears)

Onion Cookie’s skill, Unstoppable Tears, is a defining feature of her role in Cookie Run: Kingdom, and it sets her apart in both mechanics and personality. As a Support-type Cookie stationed in the Middle line, she does not perform regular attacks like most other Cookies. Instead, she enters a state of paralysis from fear, and when her terror peaks, she lets out a piercing, mournful scream. This skill does wide area damage and reduces the enemy’s attack power, weakening them significantly.

Her combat style is symbolic of her lore—frightened and uncertain—yet capable of unleashing great emotional force when overwhelmed. In battle, a unique animation shows Onion Cookie turning tearfully toward the screen whenever she activates her skill, adding a dramatic and emotional touch that reinforces her ghostly, sorrowful theme. This design choice makes her the first Cookie in the game whose standard attack phase contributes no damage, healing, or buffs/debuffs between skill activations.

The cooldown for Unstoppable Tears is 19 seconds, giving Onion Cookie time to build up her emotional intensity through dread stacks. As these stacks accumulate, the effectiveness of her skill increases significantly. The base damage starts at 67.0% for one stack, with an increase of 0.9% damage per level, and it can ramp up to a massive 671.0% damage at 10 stacks—with roughly 9.2% additional damage per level at maximum potential.

This scaling mechanic encourages strategic deployment of her skill, especially in longer fights where dread stacks have time to build. In addition to damage, the skill reduces enemies’ Attack Power by 10.0% for 6 seconds, giving allies a critical window to deal damage while minimizing the incoming threat.

Onion Cookie’s gameplay identity in Kingdom is deeply rooted in her emotional fragility, and her skill showcases this with both visual flair and mechanical uniqueness. She doesn’t fit into conventional damage-dealing or healing roles, but instead provides a debilitating, high-burst debuff capability that can swing momentum when timed right. She works especially well when paired with units that can protect her during cooldown periods or extend battles long enough to allow her dread-based damage to shine.

In Cookie Run: OvenBreak, Onion Cookie also possesses a Magic Candy, expanding her character’s uniqueness with entirely different mechanics. When equipped, she emits a mysterious Onion Aura, which transforms normal Bear Jellies into Crying Bear Jellies that grant extra points when collected. This aura persists until a certain number of these jellies are gathered, at which point it temporarily fades. The stronger the Magic Candy’s enchantment level, the higher the point value of each Crying Bear Jelly. Furthermore, her Magic Candy Blessing distinguishes her even more: instead of earning points through destruction (as is typical for many Cookies), she gains pass-through points, which is a rare trait and adds another layer of strategy in high-score runs.

Overall, Onion Cookie is a masterclass in thematic design—her gameplay and skillset both reflect her character’s haunting sadness and emotional intensity. Though timid and unaware of her possible ghostly nature, she becomes a surprisingly potent ally, disrupting enemy formations with raw emotional energy. Whether in battle or a race for points, she excels not by aggression or brute force, but by turning her overwhelming sorrow into a powerful and uniquely effective tool.

Onion Cookie Builds

When building Onion Cookie in Cookie Run: Kingdom, selecting the right toppings is essential to enhance her performance in battle, especially given her long cooldown and the stacking nature of her skill. The most recommended topping set for Onion Cookie is (5) Swift Chocolate, which focuses on reducing cooldown time. At Level 6, each Swift Chocolate topping provides +1% cooldown reduction, totaling +5% when five are equipped. This setup allows Onion Cookie to activate her Unstoppable Tears skill more frequently, increasing her contribution to both damage and debuff application during extended battles.

Alternatively, some players may choose to build Onion Cookie with (5) Searing Raspberry toppings, which enhance her Attack (ATK) stat. Each Searing Raspberry at Level 6 grants +1% ATK, adding up to +5% total. This build is ideal for situations where maximizing her damage output through her scream is the priority. Although less common, (5) Bouncing Caramel toppings are another option, boosting her Attack Speed (ATK SPD). At Level 6, these provide +0.4% ATK SPD each, totaling +2%. While Onion Cookie does not perform regular attacks, some players may use this set in specific niche strategies or purely for experimental purposes.

Upgrading toppings is a vital part of optimizing Cookie builds, and understanding the success rates of topping upgrades can help conserve valuable resources. Topping upgrades begin with a 100% success rate at Levels 1–2, but the chance of success gradually declines with each level:

  • Level 3: 90%
  • Level 4: 80%
  • Level 5: 70%
  • Level 6: 65%
  • Level 7: 50%
  • Level 8: 45%
  • Level 9: 40%
  • Level 10: 35%
  • Level 11: 30%
  • Level 12: 25%

Because higher-level upgrades have lower success rates, players are encouraged to use upgrade materials wisely and consider stopping at certain key levels, such as Level 6, to maintain cost-efficiency while still gaining a notable stat boost. In Onion Cookie’s case, maximizing cooldown efficiency with mid-level Swift Chocolate toppings often delivers the best balance between investment and performance.

Onion Cookie Teams

When building a strong team around Onion Cookie in Cookie Run: Kingdom, it’s essential to take her unique combat role into consideration. As a Support Cookie with no regular attacks and a skill that requires dread stacks to scale, Onion Cookie excels in compositions where her utility—primarily area damage and enemy Attack Power reduction—can shine without being relied upon as a primary damage source. This means she pairs best with Cookies that can output consistent DPS or mitigate incoming damage while her long skill cooldown cycles through.

A well-rounded recommended team for Onion Cookie includes Cherry Blossom Cookie, Black Raisin Cookie, Rye Cookie, and Purple Yam Cookie. This lineup covers key roles: Cherry Blossom Cookie and Black Raisin Cookie offer strong AoE damage, allowing control over waves of enemies; Rye Cookie brings focused single-target burst, ideal for quickly taking down enemy backline threats such as healers and ranged units; Purple Yam Cookie adds a durable frontline presence with disruptive, continuous damage. In this formation, Onion Cookie plays a supportive burst-debuffer, softening enemies with her scream while reducing their damage output, helping the rest of the team survive and finish the fight more easily.

For a more adaptable and sustainable formation, a perfect team composition often follows the general template of 2 Durable Cookies, 2 Damage Cookies, and 1 Healer Cookie. This balance ensures the team can handle both defensive and offensive challenges across various PvE and PvP scenarios. In this setup, the two Durable Cookies—typically frontline defenders or charge-type Cookies like Hollyberry Cookie, Wildberry Cookie, or Strawberry Crepe Cookie—hold enemy aggro and protect squishier allies. The 2 Damage Cookies, such as Clotted Cream Cookie, Sea Fairy Cookie, Black Pearl Cookie, or Moonlight Cookie, deliver continuous or burst damage. A Healer Cookie like Pure Vanilla Cookie, Cream Unicorn Cookie, or Sparkling Cookie ensures the team stays alive through longer engagements.

Onion Cookie can be seamlessly inserted into this structure, particularly by replacing one of the traditional Damage or Support slots. While she does not heal or deal consistent damage, her burst AoE skill and Attack Power reduction debuff make her effective at mitigating threats and weakening enemies, especially during the early to mid stages of a battle. Her strength grows as dread stacks accumulate, making her more effective the longer the fight goes on—especially valuable in boss fights or arena battles where survivability and endurance are key.

Ultimately, Onion Cookie works best when paired with teammates who can compensate for her lack of auto attacks and healing. By creating synergy between her debuff utility and other Cookies’ consistent offense or defense, players can build a team that is both balanced and strategic, making full use of Onion Cookie’s emotional yet powerful combat style.

Onion Cookie in Cookie Run: OvenBreak

Onion Cookie made her debut in Cookie Run: OvenBreak on September 17, 2020, at 9:00 (GMT +9), alongside her companion Pet, Onion Fish. Upon release, she was classified as an Epic Cookie, though her rarity was later changed to Rare when she appeared in Cookie Run: Kingdom. Her gameplay in OvenBreak revolves around a hauntingly thematic skill that fits her ghostly persona and tragic charm.

Her skill activates at regular intervals, causing Onion Cookie to enter a haunted house filled with eerie, moving furniture obstacles. While inside, she earns points by passing through these obstacles, rather than destroying or dodging them. The base skill triggers every 30 seconds at both Level 1 and Level 15, and can be shortened to 28 seconds when her Magic Candy reaches Level 5. As Onion Cookie levels up, the Furniture Pass-thru Points she gains also increase, enhancing her scoring potential in competitive runs.

Her Combi Pet, Onion Fish, adds another layer of scoring consistency. At maximum Affection, it grants +7,000 Furniture Pass-thru Points, with a milestone of +3,500 points at 800 Affection. It also adds +750,000 Furniture Pass-thru Points passively, significantly amplifying Onion Cookie’s point yield in haunted house segments. This makes the pairing highly synergistic for themed maps or point-focused game modes.

Onion Cookie also received a Combi Bonus with the Haunted Snuggly Bear treasure in July 2022. This treasure grants +1,650 points for all Bear Jellies, giving her an additional scoring boost, especially useful in levels populated with large amounts of Bear Jellies. This synergy complements her passive, non-destructive scoring style, offering another reliable way to rack up points.

Narratively, Onion Cookie appears in a variety of in-game stories, further developing her background and interactions with other Cookies. She plays roles in Spooky Spider Mansion, Spooky School Experience!, Cookie Court of Justice, Time Relic Chaos!, Seaside School Club Festival, and Party Time!, showcasing her continued presence in themed story events. Additionally, she’s featured in several seasonal and special events, such as New Year’s Greetings!, Wish Festival!, Special Guests at the Merrybear Toy Shop!, Cookies’ New Year’s Resolutions!, and Valentine’s Chocolate Delivery!. Notably, the Special Guests at the Merrybear Toy Shop! event is exclusive to child Cookies, reinforcing Onion Cookie’s status as a minor in the Cookie world.

Overall, Onion Cookie’s OvenBreak design reflects her delicate, haunted nature. She thrives in maps and event stages where pass-through mechanics and combo scoring are key, and her appearances across stories and events highlight her emotional depth and consistent relevance in the Cookie Run universe.

Relationships

In Cookie Run: Kingdom, Onion Cookie has a unique and intriguing set of Bonds with various Cookies, reflecting her ghostly nature and complex relationships. One of her notable Bonds is Ghost of the Tower, where Onion Cookie is referred to as “a child.” This further highlights her vulnerable and mysterious persona, hinting at a tragic past connected to the tower, where she may have met her untimely fate.

Within the Trust category, Blackberry Cookie takes on a nurturing, protective role toward Onion Cookie, acting as a caretaker out of her own volition. Blackberry Cookie goes so far as to return Onion Cookie’s cherished doll and guide her safely home, expressing relief and happiness that Onion Cookie is okay. Despite this care, Onion Cookie seems to feel more comfortable with White Ghost Cookie, possibly because they share a similar ghostly nature, allowing them to bond over their shared experience. Together, they can play at the school, providing Onion Cookie with a sense of normalcy amidst her haunted existence.

In terms of Friendly relationships, Onion Cookie interacts with several Cookies, each reflecting different aspects of her character. Adventurer Cookie seems to have a vague recollection of her from somewhere, asking if Onion Cookie would like to play with him, though he wonders why she seems familiar. Cheerleader Cookie reaches out to Onion Cookie when she senses her distress, telling her not to cry and reassuring her that she can overcome her fears.

Sandwich Cookie is a friend who knows a lot about things, offering some guidance or knowledge to Onion Cookie. Popcorn Cookie fascinates Onion Cookie with the cool events and things that seem to happen around her, adding an element of excitement to her life. Candy Corn Cookie greets Onion Cookie with a warm smile and candy, amazed at how ghostly Onion Cookie appears, even when standing still. Everything Pie Cookie showcases a bit of humor, not even crying when making an onion pie, which adds a lighter moment to their interactions.

Zombie Cookie sees Onion Cookie as a friend, offering a sense of camaraderie, while Truffle Cookie is welcoming, telling Onion Cookie she can stay as long as she likes in her home. Black Garlic Cookie feels that Onion Cookie is not just an ordinary Cookie, hinting at her mysterious, possibly supernatural origins. Lastly, Lollipop Cookie suggests that Onion Cookie’s rabbit doll should become friends with teddy bears, trying to create a sense of warmth and friendship around her.

In the Admiration category, Popcorn Cookie stands out as someone Onion Cookie looks up to. She admires Popcorn Cookie’s bravery in not being afraid of ghosts and finds that with Popcorn Cookie around, things seem to get more exciting, much like a scene from a movie.

However, not all relationships are entirely positive, as Onion Cookie experiences some Tension with certain Cookies. She asks Fairy Cookie if she is a flying ghost, indicating her curiosity and unease about other supernatural beings. Truffle Cookie makes Onion Cookie feel uneasy, as she finds her house too spooky for comfort. Black Garlic Cookie raises suspicion from Onion Cookie, who wonders why she’s following her, possibly indicating her discomfort around this mysterious Cookie.

Gim Cookie also catches Onion Cookie’s attention, as she wonders why everyone seems to be staring at her. Gim Cookie, in turn, comments that some ghosts are unaware of their own spectral nature, hinting at a deeper existential confusion. Vampire Cookie receives a question from Onion Cookie about whether ghosts follow him, possibly stemming from her own uncertainty about her ghostly status. Lastly, Dr. Bones Cookie offers a somewhat humorous yet concerned remark, warning Onion Cookie that she’ll become dehydrated if she keeps crying so much.

These varied relationships underscore Onion Cookie’s complex emotional world. Her interactions with others reveal her deep sense of vulnerability, her need for comfort, and the intrigue surrounding her ghostly existence. Whether in moments of trust, friendship, admiration, or tension, Onion Cookie’s bonds with her fellow Cookies paint a picture of a child-like spirit navigating a world full of both warmth and uncertainty.

Trivia

Onion Cookie is a unique character in the Cookie Run series, defined by her ghostly nature and the distinct qualities that come with it. In Cookie Run: OvenBreak, she does not appear in E-Z Camera’s pictures due to her invisibility as a ghost. This absence aligns with her spectral status, further emphasizing her intangible presence. Her Magic Candy Blessing is also unique, as it grants pass-thru points instead of the usual destruction points seen with other Cookies. This is likely due to the fact that boosting points for obstacle destruction would not make sense for Onion Cookie, given her inability to physically interact with obstacles in the conventional manner.

Originally introduced as an Epic Cookie in OvenBreak, Onion Cookie’s rarity was later changed to Rare in Cookie Run: Kingdom, reflecting her specific role within the game. Her Taiwanese voice actress, Xue Qing, also voices Moon Rabbit Cookie, giving the character a consistent voice across the series.

Onion Cookie’s lore suggests she may have perished during a game of hide-and-seek in the Ghost of the Tower, implying a tragic backstory that links her to her ghostly state. This connection to death is reinforced by the fact that she is one of the few Cookies whose regular attacks neither deal damage, heal, nor debuff opponents—marking her as the first Cookie to lack such offensive or supportive abilities in Kingdom. Her perpetual weeping serves as a nod to the classic effect onions have on people’s eyes, reinforcing the onion theme and her connection to sadness.

In battle, Onion Cookie has the unique feature of turning and looking at the player when attacking. This behavior is a subtle gag designed to make the player feel guilty, as if they are witnessing her sorrow firsthand. Despite her sorrowful nature, Onion Cookie is capable of smiling, though it only happens in moments of solace—when watering plants, eating, or gently caressing her cherished doll.

Within the game’s lore, Onion Cookie is referred to as “a child” in the Ghost of the Tower bond, and she is prominently featured in events that focus solely on children. This portrayal emphasizes her young age, despite her being undead. Her inability to age, coupled with her ghostly status, highlights the tragic permanence of her childhood state, forever locked in a spectral form.

Costumes

Onion Cookie’s White Tears ability changes her appearance to a pale, ghostly form, with the description humorously wondering if she has “cried all the purple away.” This transformation highlights the deeper, more sorrowful aspects of her character, as her tears appear even more bitter, intensifying her mournful nature.

In Cookie Run: OvenBreak, Onion Cookie also has a special costume called Eerie Classroom Pupil, which is a Super Epic costume obtained during the Spooky School Experience update. This costume adds another layer to her ghostly persona, emphasizing her connection to the eerie and supernatural while tying her into the school-themed event. The update introduced this costume to further develop her mysterious, sorrowful character in the context of the game.

Soulstone Farming

Onion Cookie’s Soulstones can be acquired through World Exploration in Cookie Run: Kingdom, specifically from the Crispia Dark Mode stages. Players can collect her Soulstones by completing the stages 4-13, 8-6, and 12-9 in Dark Mode. These stages are key locations where players can farm for Onion Cookie’s Soulstones, which are needed to unlock and upgrade her character within the game.
