BOOM! Studios and Cartoon Network Enterprises have announce Adventure Time/Regular Show, a comic crossover adventure that’s anything but regular. The six-issue limited series launches in August and will bring together the casts of the two hit Cartoon Network series into one story.

When a powerful new villain threatens to conquer Adventure Time’s Land of Ooo, Princess Bubblegum sends Finn and Jake on a desperate quest to find The Power that can save the land—a power that Skips from Regular Show just happens to be hiding! Finn and Jake’s arrival only exacerbates an existing tension between Mordecai and Rigby, and the trip back to Ooo threatens to tear two sets of bros apart… forever.

Written by Conor McCreery and illustrated by Mattia Di Meo, Adventure Time/Regular Show marks the first-ever crossover between the two properties, a fact that’s not lost on the creative team.

Through its award-winning all-ages imprint KaBOOM!, BOOM! Studios began publishing Adventure Time comics in 2012 and Regular Show comics the following year. Both comic series went on to break sales records for all-ages comic publishing. From the mind of series creator Pendleton Ward, the Emmy and Peabody Award-winning Adventure Time follows the unlikely heroes Finn and Jake, best buddies who traverse the mystical Land of Ooo and encounter its colorful inhabitants—and always find themselves in the middle of heart-pounding escapades. Created by J.G. Quintel, Regular Show chronicles the adventures of Mordecai, a blue jay, and Rigby, a raccoon, a couple of best bros in their 20s who work as groundskeepers at a local park—but would rather chill out for a bit.

Adventure Time/Regular Show #1 features a connecting main cover by Phil Murphy (both covers will ship in a 50/50 intermix), a subscription cover by Jorge Corona that pays homage to an Avengers vs. X-Men #1 cover, and a mash-up homage cover by Dustin Nguyen, featuring Mordecai and Rigby emulating the Adventure Time title card.
