MAGIC MAN IS UP TO HIS OLD TRICKS AGAIN … IT’S TIME TO TAKE THE “TEST OF HEROES”! Oni Press and Warner Bros. Discovery Global Consumer Products are proud to announce Adventure Time #13 – the FIRST ISSUE of “Test of Heroes,” the next show-stopping story arc for one of the year’s most acclaimed new comic series and a perfect new jumping-on point from writer/cartoonist Nick Winn and stellar artist John P Golden! The Magic Man’s must-read madcap reunion with Betty, Ice King, and all of Ooo’s greatest heroes will be put to the test when Adventure Time #13 hits comic stands on May 20th, 2026!

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 now 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!

Take note! The quest to save Ooo from Magic Man’s mischievous machinations starts here with these miraculous covers from series writer Nick Winn, artist John P Golden, and artist Ren Lindroos, plus a phenomenal “Magic Man Yellow” sketch variant and a bold black & white variant from Winn! Adventure Time #13 is due out on May 20th!
