Adult Swim is doing a bit of late-night spring cleaning this June, and if you grew up on weird Cartoon Network-era animation, this one is worth noting.
From Monday, June 8, Adult Swim will adjust part of its schedule by putting Teenage Euthanasia on break and sliding Metalocalypse into the 12:30 AM slot. That means Nathan Explosion and Dethklok are heading back to regular reruns, giving the death metal comedy another run on the block.
That is not the only old-school title returning. 12 Oz. Mouse is also coming back to Cartoon Network’s Adult Swim lineup, taking over from Tom Goes to the Mayor at 4:30 AM. Yes, that is a brutal time slot, but honestly, for a show as strange as 12 Oz. Mouse, airing before sunrise kind of fits the vibe.
For Malaysian and SEA fans, the practical impact may depend on how you follow Adult Swim content. Adult Swim itself is not exactly a standard local TV habit here the way anime on streaming platforms is, but its influence has always reached us through Toonami memories, YouTube clips, memes, streaming availability, and the wider adult animation fandom. If you are the kind of fan who went from Cartoon Network to Toonami to late-night animated chaos, this schedule shift is a reminder that Adult Swim still treats its older originals as part of its identity.
To be clear, these are rerun changes, not new season announcements. That matters because both shows have passionate cult followings, especially Metalocalypse. Creator Brendon Small has previously pushed back on the idea of more new Metalocalypse episodes after Metalocalypse: Army of the Doomstar, which served as a major closing chapter for the series. Dethklok is not totally buried, though — Small has continued keeping the music side alive through live performances.
12 Oz. Mouse is in a similar “legacy title” space. The series ended in 2021 after its third season and was not picked up for another one. Creator Matt Maiellaro has not turned it into a touring machine like Dethklok, but the show still has that underground Adult Swim reputation: messy, bizarre, very much not for everyone, but unforgettable if it clicks with you.
This schedule shuffle lands during a busy period for Adult Swim overall. Rick and Morty is also set to return for its ninth season, and there is a spin-off focused on President Curtis in the pipeline. Adult Swim has grown far beyond being just a late-night programming block too. Over the years, it has become home to shows like Rick and Morty, Smiling Friends, and Aqua Teen Hunger Force, while also airing major adult animated series such as Family Guy and Bob’s Burgers.
For SEA animation fans, the bigger takeaway is simple: Adult Swim is still leaning on the weird stuff that made it stand out in the first place. In a streaming era where everything is fighting for algorithm space, reruns of Metalocalypse and 12 Oz. Mouse might sound small, but they keep that oddball animation culture visible.
And honestly, that is good. Not every animated show needs to be polished, market-tested, and easy to explain. Sometimes you just need a death metal band with ridiculous lore, or a mouse show that feels like someone animated a fever dream at 4:30 AM.
