G.I. Joe. Transformers. Adult Animation: The Epic ‘Energon Universe’ Is Coming

A bold new chapter is opening for fans of action-animation. The shared franchise known as the Energon Universe—which unites the legendary brands of G.I. Joe and Transformers under the banner of mature storytelling—has taken an exciting leap off the comic-page and into development for adult animation.

Behind the scenes, powerhouse creators are writing the next evolution of this franchise. Robert Kirkman’s imprint Skybound Entertainment has partnered with Hasbro Entertainment to bring the universe to life for a more adult audience. The series adaptation is being led by Joe Henderson (known for his work on Lucifer) as writer and showrunner.

While this universe began in the comics in 2023—with titles like Void Rivals kicking things off and incorporating classic characters like the Transformers and G.I. Joe teams into a shared story world—this project signals the move into animated television with a more adult sensibility.

What does this mean for the fans? Instead of the more family-friendly tone of previous cartoons, this adaptation is explicitly aimed at adult animation fans—those who have embraced hits like Invincible. The promise is darker themes, higher stakes, and a crossover scale that brings together agents, robots, secret wars and high-tech espionage.

Although a broadcaster or streaming home hasn’t been confirmed yet, the production is actively being packaged for buyers—so it’s only a matter of time before we hear about where and when.

For fans of the original comics and toy lines, this marks a major moment: two iconic franchises merging into a single unified universe, with adult tone and serialized depth. If you’ve ever wondered what a Transformers / G.I. Joe crossover would look like with serious storytelling behind it—this is exactly that.

Stay tuned as we await more details on casting, release date and platform. In the meantime: brace yourself—this is going to be one big ride.
