The Purple Sauce Was Real—But the U.S. Battle Is No Longer a Current Menu Promotion
McDonald’s Demon Sauce 2026 was a purple mustard-based dipping sauce created for the Netflix KPop Demon Hunters collaboration and included with the HUNTR/X Meal beginning March 31.
The important July update: the promotion was limited-time, its collectible-card digital deadline passed in April, and Demon Sauce is no longer listed on McDonald’s current national U.S. full menu.

What Was McDonald’s KPop Demon Hunters Demon Sauce?
Demon Sauce was one of the special sauces developed for McDonald’s U.S. KPop Demon Hunters promotion.
McDonald’s official launch description called it a bold mustard sauce with heat and tang and emphasized its purple color as a visual reference to the film’s demon patterns.
Flavor base
Mustard-forward. This distinguishes Demon Sauce from the sweet-chili Hunter Sauce.
Flavor direction
Heat + tang. McDonald’s positioned it as the sharper, punchier sauce of the HUNTR/X pair.
Appearance
Purple. The color was deliberately tied to the demon-pattern theme of the collaboration.
Demon Sauce vs Hunter Sauce: Demon Sauce was mustard-based, hot and tangy. Hunter Sauce was the sweeter option, combining sweet chili with notes of chili, garlic and pepper.
What Came in the HUNTR/X Meal?
In the U.S., Demon Sauce was associated with the HUNTR/X Meal rather than the breakfast-focused Saja Boys Meal.
Do not mix countries: McDonald’s adapted the KPop Demon Hunters promotion differently outside the U.S. Canadian, Australian and New Zealand meals, sauces, card quantities and nutrition should not be copied into a U.S. article.
KPop Demon Hunters McDonald’s Release Date
What Was the KPop Demon Hunters McDonald’s End Date?
No official hard restaurant-sale end date was published in the U.S. launch announcement. The promotion was described as limited-time.
This distinction matters because many searches incorrectly treat April 26, 2026 as the guaranteed meal end date.

KPop items absent from current national U.S. full menu |
Confirms it should no longer be treated as a current national promotion |
Best answer for search users: the U.S. promotion launched March 31 for a limited time; April 26 was the digital-card deadline, not a clearly published national restaurant end date. By July, the promotion is no longer part of McDonald’s current national U.S. menu.
KPop Demon Hunters McDonald’s Price: Was There a National Price?
No single official nationwide HUNTR/X Meal or Demon Sauce price was published in McDonald’s national launch release.

How Many Calories Were in Demon Sauce?
Current U.S. answer: an exact standalone Demon Sauce calorie figure could not be verified from McDonald’s available official U.S. launch material or its current U.S. menu, so this guide does not invent one.
Why you may see “140 calories” in search results
Canadian delivery/menu listings show a 140-calorie “Demon Sauce: Purple Cajun Sauce”. Canada launched its version of the promotion later and described its Demon Sauce as Purple Cajun.
The official U.S. version was described instead as a bold purple mustard sauce with heat and tang. Because the product naming and market formulation differ, the Canadian 140-calorie number should not automatically be assigned to the U.S. sauce.
Nutrition rule: country-specific McDonald’s formulations can differ. Use a U.S. number only when it comes from a U.S. product panel, nutrition calculator or other current U.S. McDonald’s source.
What about the full HUNTR/X Meal calories?
A single exact HUNTR/X Meal calorie number is also incomplete without the exact drink and serving configuration. The meal included a 10-piece McNuggets order, seasoned Fries, two sauces and a medium soft drink, so beverage selection changed the final total.
If you are comparing current foods rather than an expired promotional meal, use the current McDonald’s menu calories guide.
Demon Sauce Ingredients: What Is Actually Verified?
The available official U.S. launch announcement provides a flavor description, but it does not publish the complete ingredient statement for the sauce.

What Were the KPop Demon Hunters McDonald’s Cards?
Every U.S. HUNTR/X Meal and Saja Boys Breakfast Meal came with a collectible card pack.
Exclusive group photocard
The pack contained a photocard representing either HUNTR/X or the Saja Boys.
Derpy access card
This card carried a QR code and unique code used with the McDonald’s app to unlock first-access digital content.
What was the April 26 deadline?
Fans had until April 26, 2026 to scan the Derpy access card and enter its unique code in the McDonald’s app for first access to exclusive content and the Battle for the Fans winner reveal.
Do not import card counts from other countries. For example, Canada later offered two randomized photocards per pack and Australia promoted 13 collectible cards. Those are not the official U.S. card rules stated in the March U.S. launch announcement.
Did McDonald’s KPop Demon Hunters Have Toys?
U.S. answer: no standard Happy Meal toy was included with the KPop Demon Hunters adult meals. The collectible was a card pack.
Search results sometimes use “toys,” “collectibles” and “adult Happy Meal” interchangeably, but that hides an important distinction.

KPop Demon Hunters Happy Meal: Is It Real?
The McDonald’s collaboration was absolutely real. What needs clarification is the phrase “Happy Meal.”
McDonald’s official U.S. announcement described the promotion as two new meals for adults: the HUNTR/X Meal and Saja Boys Breakfast Meal. Many media outlets informally called them “adult Happy Meals” because they combined themed food, collectible packaging and cards.
Real collaboration?
Yes. Official McDonald’s × Netflix U.S. promotion.
Kids Happy Meal?
No. Official U.S. launch centered on two adult meals.
Toys inside?
No standard toy. The promotion used collectible photocards and a Derpy access card.
Is Demon Sauce Still Available in July 2026?
Do not treat it as a current nationwide U.S. item. On July 30, McDonald’s current full U.S. menu lists Caesar Sauce and standard sauces, but not Demon Sauce, Hunter Sauce or the KPop Demon Hunters meals.
McDonald’s current July promotional focus has moved to newer offers including the BT21 Happy Meal, Honey Brown Butter Bacon, Egg & Cheese Biscuit and Caesar Sauce chicken lineup.
Could a restaurant still have leftover sauce?
It is theoretically possible for a location to have unusual leftover inventory, but that should not be presented as current national availability.
If Demon Sauce does not appear after selecting the exact restaurant in the McDonald’s app, treat it as unavailable there.
How to Check Whether Demon Sauce Is Still Available Near You
Use the McDonald’s app or restaurant locator and confirm the full address.
Pickup gives the clearest restaurant-menu view without delivery-market differences.
Look specifically for Demon Sauce rather than assuming an old promotion page means it remains stocked.
Limited sauces can sometimes appear only as an available add-on to qualifying food.
If the menu shows Caesar or another current limited sauce instead, the KPop promotion has likely been replaced at that restaurant.
Search results can retain March or April promotional information after restaurant inventory has ended.
Common KPop Demon Hunters McDonald’s Search Mistakes
Search result claim |
What is wrong? |
Correct interpretation |
|---|---|---|
“The promotion ended April 26” |
April 26 was specifically the Derpy access-code deadline |
No hard national meal-sale end date was published in the launch release |
“Demon Sauce is 140 calories” |
That number appears on Canadian Purple Cajun listings |
Do not apply it automatically to the U.S. mustard-based sauce |
“It came with toys” |
U.S. adult meals used photocards |
BT21 is the separate current July toy promotion |
“The meal cost $13.79 everywhere” |
That was a published reviewer’s purchase example |
Restaurant prices varied |
“Demon Sauce is still current because I found a product result” |
Old/cached promotion pages can remain indexed |
Check current national menu and selected restaurant |
“Canada’s KPop meal is the same as the U.S.” |
Canada used different timing, sauce naming and card structure |
Use U.S.-specific sources for a U.S. article |

A reliable standalone calorie number for the U.S. 2026 Demon Sauce could not be verified from the available official U.S. launch material or current U.S. menu. A 140-calorie Purple Cajun Demon Sauce appears on Canadian listings and should not automatically be applied to the U.S. formulation.
What ingredients were in Demon Sauce?
The available official U.S. material verifies a mustard-based profile with heat, tang and purple coloring, but it does not provide the complete current ingredient statement. This guide does not invent the missing formula.
