Oni Press May 2026 solicitations: Adventure Time (2025) #13
Here's our first look at Adventure Time (2025) #13 from the Oni Press May solicitations. This new arc will be titled "The Test of Heroes". This issue releases on 20 May 2026 and will retail for $5. Here's the blurb:
Magic Man causes mayhem in this brand-new adventure (time!) by cartoonist/writer Nick Winn (Bloody Mary) and stellar artist John P Golden (Over the Garden Wall)! More at 11! Why was Magic Man using Finn's robotic doppelgänger to steal important artifacts from across Ooo? To impress the one and only Betty Grof, of course! Now a resident of Mars, Betty used to travel Ooo with Marceline and one Simon Petrikov—better known as Ice King! But this family reunion takes a turn for the worse when Magic Man's jealousy gets the better of him and he accidentally—maybe—starts the apocalypse . . . A sleight of hand turns sour, and a TEST OF HEROES begins! Can Finn, Jake, Marceline, Princess Bubblegum, and more of your favorite concerned citizens band together to save their home? One thing's for sure—after this exam, Ooo will never be the same . . .
The alternate timeline for this comic is getting pretty crazy. John P Golden will be the artist for this issue. There doesn't seem to be a backup story as far as I can tell.
