The Powerpuff Girls and Teen Titans GO! will meet in a crossover episode between cartoon superhero reboots next month, Cartoon Network says.

Teen Titans GO! producer Aaron Horvath reports that the two youthful superheroic teams will run into each other when the Powerpuff Girls’ nemesis Mojo Jojo enters Jump City, hometown of the Teen Titans. The grumpy talking monkey supervillain will encounter Titans members Cyborg and Beast Boy, who, in typical TTG fashion, decide that he’s “pretty cool” and befriend him rather than fighting him. The Powerpuff Girls leave the city of Townsville, USA, to follow the giant-brained evil monkey suspecting him of being up to no good, and crossover antics ensue.

“Jump City will never be the same when our little superheroes Blossom, Bubbles and Buttercup meet up with the Teen Titans for the very first time. When these two worlds of superheroes collide, it will surely be something to remember,” says executive producer of ThePowerpuff Girls, Nick Jennings.

Fans have also been teased with the promise of a new song in the episode called “Monkey Army” that’s “bound to get stuck in fans’ heads.”

The two shows have a lot in common, making the crossover not surprising or coming across as terribly forced. In addition to their shared themes of super-powered children teaming up to fight crime in loose, fantastical narratives full of gags, TTG and PPG are, in their current incarnations, both reboots of previously-cancelled cult classic shows. The original Craig McCracken-created The Powerpuff Girls aired from 1998-2005, and the Glenn Murakami created/produced Teen Titans Go! ran from 2003-2006.

Aaron Horvath confirmed that the collaboration was as natural a fit as fans would assume.

“It’s a really fun crossover that came about in a very organic way,” he said, “and it was really great getting to put these two iconic superhero teams together.”

The Powerpuff Girls made its reboot return just last month after more than a decade on the shelf. It features the adventures of the three super-powered girls: Blossom, Buttercup and Bubbles and their creator, Professor Utonium, who are called upon to save the city of Townsville from attack by various bizarre super villains. The series was beloved by many fans and racked up nominations for six Emmy Awards, nine Annie Awards, and a Kids’ Choice Award. TV Guide ranked the show’s original run number 17 on a list of the 50 greatest cartoon characters of all time.

The original Teen Titans TV series was another one of Cartoon Network’s most critically-acclaimed shows, securing nominations for three Annie Awards and one Motion Picture Sound Editors Award for its strong production, character development, and exploration of serious themes. The current spin-off Teen Titans Go! differs substantially from the Powerpuff Girls reboot in that it completely changed animation styles and even the genre from its parent series, moving from a serious exploration to an entirely comical satirization of the DC franchise. This series focuses more on what the Titans do when they’re not saving the world and the shenanigans that super-powered teenagers can get into when they’re left unsupervised. Cameos from many other heroes and characters in the DC universe are common, and they’re referenced frequently throughout the show.

No air date has been provided for the crossover episode yet, with USA Today reporting only that the episode will be released sometime in June.

Both shows will also individually have two-part episodes airing on Monday, with the Memorial Day edition of The Powerpuff Girls airing at 6 p.m. ET/PT, and Teen Titans GO! airing their two-part adventure at 6:30 ET/PT. The shows will as usual feature two shorter episodes in a single half-hour period.
