Watch The Grim Adventures of Billy and Mandy: Streaming Guide

You probably remember him: the green-skinned, scythe-wielding Grim who lost a limbo contest and ended up as best friends with two kids. More than two decades later, that unlikely trio from Cartoon Network is still pulling in new viewers on three different streaming platforms. Let’s sort out exactly where you can watch The Grim Adventures of Billy & Mandy right now, why it disappeared from the network, and whether any of the lingering questions — like the speculation about Billy — have ever been answered.

Original Network: Cartoon Network ·
Original Run: 2001 – 2004 ·
Available on Netflix: Yes ·
Available on HBO Max: Yes ·
Available on Tubi: Yes

Here is a quick reference on the show’s specifications from the network’s catalog.

Is Grim Adventures of Billy and Mandy on Netflix?

Yes — Netflix currently streams The Grim Adventures of Billy & Mandy. The show’s catalog page lists the title as a 2006 TV-Y7 series created by Maxwell Atoms (Netflix catalog entry). That’s one of three major U.S. platforms where you can find it.

How to watch on Netflix

• Requires an active Netflix subscription (any tier with ad-supported or ad-free)
• All seasons are available, though Netflix’s catalog page does not show a per-episode breakdown for Season 1, Episode 1
• U.S. library includes the full series; international availability may vary by region

The implication: Netflix is the most convenient option for viewers who already have a subscription, but the lack of episode-level detail means you’ll need to search within the app for specific episodes.

Is Billy and Mandy on HBO Max?

Yes — HBO Max (now often called MAX) carries the series. It was added to the U.S. catalog on January 1, 2021 (Wikipedia entry). The streaming service NOW, a U.K. partner that carries HBO content, also lists Season 1 as available (NOW TV listing).

HBO Max subscription required

• Full series included with an HBO Max or MAX subscription
• In the U.S., the show is available on the ad-supported and ad-free tiers
• Availability outside the U.S. depends on regional licensing deals

The catch: HBO Max is a paid service, but if you already have it, this is a zero-friction way to watch. For U.K. viewers, NOW carries the series under the same Warner Bros. umbrella.

Will Tubi have The Grim Adventures of Billy and Mandy?

Yes — Tubi currently offers the series for free with ad breaks. That makes it the only major platform where you can watch without any subscription fee.

Tubi is free with ads

• No subscription or sign-up required
• Accessible on web, mobile, and smart TV apps
• Library includes multiple seasons

Three streaming platforms, two of them paid, one completely free. For a show that ended two decades ago, that’s unusual staying power.

The pattern: Tubi fills the gap for cord-cutters who don’t want another monthly bill. The trade-off is commercial breaks — roughly the same rhythm as the original Cartoon Network broadcasts.

Is Billy and Mandy Disney?

No — The Grim Adventures of Billy & Mandy is not owned by Disney, and it is not available on Disney+. The series was produced by Cartoon Network Studios, a Warner Bros. property, and its streaming home remains within Warner Bros. Discovery’s ecosystem (HBO Max, Cartoon Network’s own platform) plus licensed deals with third-party services like Netflix and Tubi.

Not on Disney+

• Disney+ does not carry the show
• The characters and intellectual property belong to Warner Bros. Discovery
• No cross-licensing agreement has placed it on Disney platforms

Why this matters: if you’re searching for the show on Disney+, you won’t find it. Stick to Netflix, HBO Max, or Tubi — that’s where the Grim adventures actually live.

Why was The Grim Adventures of Billy and Mandy cancelled?

The series ended its original Cartoon Network run in 2004 after four seasons on air. The official reason has never been stated explicitly by the network, but multiple industry reports point to declining ratings and a strategic shift in Cartoon Network’s programming direction toward newer titles.

Network decisions

• Final episode aired November 9, 2007, in some markets, though the last new episode produced for the original series was in 2004 (Wikipedia entry)
• Reruns continued on Cartoon Network for several years after cancellation
• The show’s 7-season packaging (by some sources like Reelgood catalog) includes split seasons and rebroadcast cycles

Creative reasons

• Creator Maxwell Atoms has never publicly stated that the show was creatively “finished” — it was a network decision
• The show’s dark humor and macabre tone may have fallen out of favor as Cartoon Network shifted toward more action-oriented programming in the mid-2000s
• No reboot has been officially announced as of 2025

The speculation about Billy’s autism has been a persistent fan theory for years. The show has never officially addressed it, and creator Maxwell Atoms has not confirmed or denied it in interviews.

The trade-off: fans who want a definitive answer on the cancellation reason — or a reboot — remain waiting. The show’s streaming presence suggests there’s still audience demand, but Warner Bros. Discovery hasn’t acted on it publicly.

Frequently asked questions

For fans in the U.S., the choice is straightforward: if you already pay for Netflix or HBO Max, watch it there. If you don’t want another subscription, Tubi gives you the full series at no cost — just with commercial breaks. The show’s surprising persistence across three major platforms two decades after cancellation shows that audiences still want more Grim adventures, even as Warner Bros. Discovery has not yet acted on that demand.
