If you've been missing the golden age of Cartoon Network, Tubi has your back. The free, ad-supported streaming service is doubling down on nostalgia with a fresh batch of animated favorites arriving August 1, 2026. Among the highlights are three shows that have become notoriously hard to stream: The Grim Adventures of Billy & Mandy, Freakazoid!, and Green Lantern: The Animated Series.
This marks the third wave of classic cartoons Tubi has rolled out since it inked a massive deal with Warner Bros. earlier this year. The platform already brought over 100 titles from the Warner Bros. vault, including Justice League, Dexter's Laboratory, and Courage the Cowardly Dog, after finding huge success with its Looney Tunes library. Now, it's filling the gap left by HBO Max, which purged most of its Cartoon Network content over the past couple of years.
What's Coming to Tubi in August 2026?
The August lineup is a treat for '90s and early 2000s kids. The Grim Adventures of Billy & Mandy—a show that turned a grim reaper into a sitcom sidekick—arrives along with its holiday special, Billy & Mandy Save Christmas. Also joining the roster is ¡Mucha Lucha!, a high-flying luchador cartoon that never quite got its due, and Freakazoid!, the manic superhero spoof from the minds of Bruce Timm and Paul Dini, executive produced by Steven Spielberg.
For DC fans, Green Lantern: The Animated Series is a major get. The CGI series, which ran for one season in 2012, came from the same creative team behind Batman: The Animated Series and Superman: The Animated Series. It's a perfect primer ahead of HBO Max's upcoming Lanterns live-action series. And if you're in the mood for something spooky, the Beetlejuice animated series—a Fox Kids hit that expanded on Tim Burton's film—is also included.
Why Tubi Is Becoming the Go-To for Classic Cartoons
Tubi's strategy is simple: give fans what they can't find elsewhere. After HBO Max stripped its library, Tubi swooped in to become the unofficial home for Cartoon Network's back catalog. The platform even greenlit Yokoso Scooby-Doo!, the first-ever Scooby-Doo anime series, set to debut as a Tubi exclusive. That show will feature Frank Welker and Matthew Lillard reprising their roles as Scooby and Shaggy for a foodie adventure in Japan.
While some titles like Batman: The Brave and the Bold and Pinky and the Brain are cycling out of Tubi soon, the August wave ensures there's always something new to discover. The service is also adding Looney Tunes: 3D Shorts and other Kids WB staples to round out the selection.
What Else Is Streaming on Tubi?
If you're looking for more animated goodness, Tubi's library now includes deep cuts like Krypto the Superdog and ¡Mucha Lucha!. And for those who prefer live-action, the platform has been expanding its original programming too. For instance, Billy Bob Thornton's 'Goliath' surges on Prime Video as a July 2026 streaming hit, showing that the streaming wars are far from over.
But for now, the spotlight is on Tubi's cartoon renaissance. Whether you're revisiting Billy's grim misadventures or catching up on Hal Jordan's space-faring heroics, August 1 is the date to mark on your calendar. And if you're a fan of classic animation, you might also enjoy our ranking of Spider-Man video games—because sometimes the best stories aren't just on screen.
So grab some popcorn, fire up Tubi, and get ready to relive the cartoons that defined a generation. All for free, with a few ad breaks—but hey, that's a small price for a trip down memory lane.
