The Land of Ooo was recently thrown into turmoil when the Master of Division attacked the peaceful residents of the Candy Kingdom. In order to save the day, Finn, Jake, Marceline, Lumpy Space Princess, and Ice King made the dangerous journey to The Park. While there they came face-to-face with Regular Show alums such as Mordecai, Rigby, Skips, Benson, and Pops.
While tracking down the Power needed to save the Candy Kingdom, the Master of Division uses his powers of separation to divide the friends. After getting captured and locked up, the team decides to use Jake to double cross the Master of Division. Unfortunately, this plan goes awry when Mordecai and Rigby fall into an ultimate bro divide. As these former friends attempt to tear each other apart, the rest of the friends are pulled into the massive battle. Can Mordecai and Rigby overcome the curse, or will both the Adventure Time and Regular Show fan-favorites be destroyed?
Conor McCreery has crafted an epic conclusion to this long-awaited crossover that any fan of the Cartoon Network shows is sure to enjoy. Meanwhile the cartoonish art by Mattia Di Meo brings the whole story together.
