WBA Unveils Genndy Tartakovsky’s ‘Conan The Barbarian,’ ‘Bubblegum And Marceline’ Spinoff, And More

Genndy Tartakovsky is finally making his Conan the Barbarian animated series, partnering with Cartoon Network Studios and Prime Video to release the project.

Tartakovsky has been pitching the project since 2008 to no avail.

“The world wasn’t ready,” he said during a video message at a studio spotlight panel for Warner Bros. Animation, Cartoon Network Studios, and Hanna-Barbera Studios Europe at the 2026 Annecy Animation Film Festival. “But now, after adult Samurai Jack and Primal, it is prime, not just Prime Video, but prime for this story to come to the screen.”

Though no footage was shown, the first poster for Conan teases the titular barbarian drawn in the recognizable Tartakovsky style. This will be the first pre-existing IP that Tartakovsky has worked with since the 2003 Star Wars: Clone Wars micro-series. As Tartakovsky said in the video message, however, Robert E. Howard’s character has influenced a lot of his work over the years, especially Primal. The animator joked that maybe he’ll be back at Annecy next year with some rough animation for Conan.

In addition to Conan, Warner Bros. Animation announced that Adam Muto and the team behind Fionna and Cake are back with a new Adventure Time spin-off, titled simply: Bubblegum and Marceline. This is a hugely anticipated spin-off based on beloved characters from the franchise, and proof that the Adventure Time franchise still has life in it.

The presentation was a showcase for the variety of cartoons that Warner Bros. Animation has in production.

First up was Yokoso Scooby-Doo!, the first proper anime starring the famous Great Dane. The show will follow Shaggy and Scooby traveling through Japan and fighting all sorts of monsters inspired by Japanese culture. The series is animated by OLM (Oriental Light and Magic), the studio known for Pokémon, which explains why it prominently features monsters being caught in balls. Footage from the show featured a new anime-styled Shaggy, but the same old Scooby.

“We didn’t really change the design that much,” Senior Vice President of Current Series at Warner Bros. Animation Jay Bastian said. “You don’t really mess around with perfection.”

Footage from a brand-new Foster’s Fun Time With Imaginary Friends received a huge reaction from the crowd at Annecy, more than ready to be reunited with the beloved characters from Craig McCracken’s series, now in 3D form. Fear not, the humor and the characters remain the same, though there are plenty of new imaginary friends to meet. Visually, the show seems to combine art styles, just like the original series, with characters rendered in different forms, including an imaginary friend that looks like stop-motion, a 2D character, and more.

One of the most exciting projects in the works at the studio is SuperMutant Magic Academy, based on the 2015 comic by artist and writer Jillian Tamaki. Ahead of its Adult Swim premiere, footage was presented during the studio spotlight, introducing a unique blend of teen comedy and fantasy. There are dragons, goblins, magic, relationship drama, cliques, gossip, and much more. This one looks like a sure-fire hit.

Lastly, Annecy audiences got to see two episodes of the upcoming Adventure Time: Side Quests before its release later this year. The first episode follows Finn and Jake at a medieval fair, trying various classic games like crossbow shooting and house throwing. Finn, trying to show off his skill, accidentally gets involved in a William Tell-style contest involving shooting apples off people’s heads.

The second episode follows the Ice King having to take care of a goblin prince while his mother, Ice King’s girlfriend Queen Infernosa, is out committing crimes. It’s been eight years since the original Adventure Time ended, but it feels like no time has passed. The characters are just as you remember them, the animation is crisp, and the humor is on point.
