Quick answer
The Jack in the Box Doomsday Dipping Box launched November 5, 2026, for Avengers: Doomsday. It has popcorn chicken, two mozzarella sticks, two tacos, seasoned curly fries, a drink and three sauces: the new Assemble Sauce, Mutant Marinara and Fantastic Buttermilk Ranch, plus one of eight blind-bagged magnets. It was $14.75 at the San Diego and Houston restaurants that were checked on launch day. Assemble Sauce is a new 'mystery' sauce; an early reviewer said it tastes similar to Thousand Island with a little spice.

What does Assemble Sauce taste like?
Jack in the Box only calls it "an all-new mystery sauce" and hasn't listed its ingredients. In the promo photo it's a creamy, yellow-orange dip. The first tasters describe it like this:
- Haunted Attraction Network: "similar to Thousand Island with a little spice"
- Laughing Place: "very tasty"
So think tangy burger-style sauce with a mild kick, not a hot sauce. It's paired with the Avengers on the box, while Mutant Marinara goes with the X-Men and Fantastic Buttermilk Ranch with the Fantastic Four.
Can you buy Assemble Sauce by itself?
Jack in the Box hasn't said it's sold separately. It comes in the Doomsday Dipping Box. The popcorn chicken and mozzarella sticks are also on the menu on their own, with Mutant Marinara back as a limited-time sauce. Ask for an extra Assemble Sauce at the window or check the Jack app; extra sauces are up to each restaurant.

Collecting all eight takes at least eight boxes (about $118), and likely many more since they're random.
