BRAND-NEW #1! A supremely intelligent madman and his teen sidekick scour the multiverse for the elements of the perfect world—a world of pure mathematics. Also, a different supremely intelligent madman and his teen sidekick are on a quest for a space milkshake. Supposed to taste pretty good. When Goldenfold, not Rick Sanchez, leads the pursuit of madcap adventure and groundbreaking knowledge, things are going to get... well, interesting in that weird, can't-look-away sense.

The invasion continues! War brews between the Goldenfold and Rick armies. Can the Ricks save their world with problem-solving science, or will the Goldenfolds subtract them from the equation? Yep, it's still about math! Oh, and Morty's new girlfriend seems...nice?
