Mobile Suit Gundam RG XARX-ZERO Premieres April 2027: Kenji Kamiyama Directs for SOLA ANIMATION, Plus How It Ties Into GUNDAM ROGUE ORBIT

Kenji Kamiyama’s new Gundam TV anime, Mobile Suit Gundam RG XARX-ZERO (pronounced “Alex Zero”), will premiere on television in April 2027. SOLA ANIMATION is handling animation production, with Kamiyama serving as both director and series composer. The show’s official website announced the premiere window on September 14, 2026, and published an interview with Kamiyama at the same time.

The series is the centerpiece of the “RG Project,” a franchise that tells the story of a single world across both anime and games. It shares its setting with the action game GUNDAM ROGUE ORBIT (releasing March 5, 2027), which comes out first, and the anime covers roughly 100 years before the game—the “age of beginnings.” In other words, this is a Gundam set in a completely new timeline, neither the Universal Century nor the Anno Domini era.

When the project was revealed in July, the only info we had was “rolling out in 2027.” Now that’s been narrowed down to “April 2027, on TV,” and confirming this isn’t a streaming-only release is a big deal. As a middle-aged guy raised on the Saturn and the Dreamcast, just knowing a new Gundam is landing in the spring season has me restless already.

That said, the broadcaster and time slot haven’t been announced yet. This article sticks to what’s officially confirmed as of September 15, 2026. Along the way, I want to keep one question in mind and come back to it at the end: how is Kenji Kamiyama going to rebuild Gundam?

Let’s start with the premiere date and the basics. *This article reflects information as of September 15, 2026.

When Does Mobile Suit Gundam RG XARX-ZERO Air? Is There a Broadcaster Yet?

The TV broadcast starts in April 2027. The broadcaster and time slot, however, have not been announced yet.

A news post dated September 14, 2026, on the official website states that “a TV broadcast has been confirmed for April 2027” (checked on the official site as of September 2026). Coverage from Famitsu, Anime! Anime!, and other outlets says the same thing, and I couldn’t find any outlet that revealed the network, day of the week, or time slot. No streaming service has been announced so far either.

The pronunciation is worth noting too. It’s written “XARX-ZERO,” but the official reading is “Alex Zero.” The official account uses two hashtags—#XARXZERO and a Japanese-script tag that reads “Alex Zero”—so try both when you search.

Until we know the broadcaster and streaming platform, there’s no way to plan how to watch. Keep an eye on the official website and the official Gundam X account for updates.

Who Are the Director, Staff, and Cast? Kenji Kamiyama and the SOLA ANIMATION Team

Kenji Kamiyama directs and handles series composition, Toh EnJoe supervises the sci-fi setting, and Takeo Otsuka voices protagonist Rei Azumi.

According to his profile on the official website, Kenji Kamiyama was born in Saitama Prefecture in 1966. He served as director and series composer on the TV anime Ghost in the Shell S.A.C. He also co-directed ULTRAMAN (2019) and Ghost in the Shell: SAC_2045 (2020) with Shinji Aramaki, and directed the film The Lord of the Rings: The War of the Rohirrim (2024). A director who’s equally at home with sci-fi and action is finally taking the helm of a Gundam series.

As of September 15, 2026, the only announced cast member is Takeo Otsuka as protagonist Rei Azumi. The heroine and rival roles haven’t been revealed yet. With an April premiere, expect a batch of cast announcements around the second trailer.

The visual and sound team is already locked in too: Eiichi Shimizu on Gundam design, STATO on original character design, and Go Shiina on music. What kind of mecha and music will they use to bring humanity’s war against the Apocalypse to life? I can’t wait for that second trailer.

What’s the Story? What Is “A.A. 45” and the Series’ Own Timeline?

It’s a story set in A.A. 45, in which a humanity that has abandoned Earth fights a self-replicating enemy called the “Apocalypse.”

According to the STORY section of the official website, humanity prospered thanks to three technologies brought from beyond the solar system: “gravity control,” “faster-than-light communication,” and “materialization” (a technology that turns images into physical matter). But the interstellar object that was the source of that technology went haywire, giving birth to an aggressive self-replicating system called the “Apocalypse.” After three months of fighting, the front line stalled in satellite orbit, and humanity abandoned Earth. That year was recorded as “A.A. 1” (After Apocalypse).

The story picks up 45 years later, when a boy named Rei Azumi wakes up on the surface of the Moon. Rei is a war orphan who lost his parents in an Apocalypse attack, and he becomes the dedicated pilot of the cutting-edge anti-Apocalypse experimental unit “Gundam ZERO” (model number XARX-0).

It is the story of the battle between humanity and an interstellar object that arrived from beyond the solar system (later called the Apocalypse) over the right to survive on Earth, and of the conflicts and growth of the boys and girls that unfold against that backdrop.

Building the show around “humanity’s war for survival against an unknown enemy” rather than “people waging war on people” is a pretty bold move for Gundam. At the same time, the core of “the conflicts and growth of boys and girls” hasn’t changed since the original Mobile Suit Gundam. Swap out the enemy all you want—it’s still about kids thrown onto the battlefield.

In the same interview, Kamiyama states outright that the show is on “this series’ own timeline.” He also says he named the protagonist “Rei” because he wanted viewers to intuitively understand that, even in this new world, he’s the hero. He mentions that a character clad in red will appear as well. It’s impossible not to think of Amuro Ray and the “Red Comet.” That’s a nod longtime fans will grin at.

For the record, this interview is a compilation of remarks originally published by Gizmodo (io9) and AUTOMATON, republished in Japanese on the official website.

How Does It Connect to GUNDAM ROGUE ORBIT? Release Date and Platforms

The game GUNDAM ROGUE ORBIT depicts the world about 100 years after the anime and releases on March 5, 2027.

According to the announcement Famitsu reported in July, the anime is set about 100 years before the game’s story and serves as the “starting point” for that world. The game’s official website describes the “RG Project” as an effort to portray a shared world created by director Kenji Kamiyama and Toh EnJoe across multiple media, including anime and games.

In the interview, Kamiyama also walks through how the two teams worked together. First, the game side pitched the concept of “a Gundam fighting giant, space-monster-like mecha.” The anime side took that and built out the enemy’s true nature and the structure of the war, and the game side then designed a setting 100 years after that. In other words, the “image of the enemy” came from the game, and the “origins of the world” came from the anime.

The game comes out a month earlier, but chronologically the anime comes first. Do you play through the world 100 years later and then learn its “starting point” from the anime, or wait for the broadcast? Either route looks like fun, but it’s shaping up to be a spring spent agonizing over the right watch order.

What’s Promising About the New Gundam, and What Gives Us Pause?

The promise lies in Kamiyama’s creative voice and the fresh world design. The concerns are the still-unannounced broadcaster and how much the story leans on the game tie-in.

What Looks Promising

• An original timeline with no link to the Universal Century or any existing continuity, so it’s easy to jump in without having seen past shows
• A hard-hitting sci-fi setting from Kenji Kamiyama and Toh EnJoe
• Callbacks to the original Mobile Suit Gundam, like the name “Rei” and a character in red
• An unusual structure that depicts the same history from different eras in the game and the anime

Kamiyama’s comment released with the July announcement includes the line, “Just getting the chance to build my beloved Gundam from zero in the Reiwa era? That’s the best!” He says the project first came to him about five years ago, so this broadcast announcement follows a long runway. When a director who’s openly a Gundam fan says he’s building it “from zero,” it’s hard not to get your hopes up.

What Gives Us Pause

• The broadcaster, time slot, and streaming service are all TBA, so we still don’t know where to watch
• Episode count and number of seasons are also TBA
• It’s unclear whether the anime’s story will stand on its own or need the game to fill in the gaps
• How longtime Gundam fans will take to a “humanity vs. unknown enemy” setup

My biggest worry is how fully the anime can portray this world on its own. Multimedia projects tend to turn into “you won’t get it unless you follow everything,” and no amount of money or free time is ever enough. …Then again, a twice-divorced guy like me has no business lecturing anyone about time management. Still, Kamiyama says he left the “100 years later” part to the game side, so the anime should deliver a complete story as the “starting point.”

The Bottom Line: Kenji Kamiyama’s New Gundam Anime Airs April 2027, Broadcaster Still TBA

Mobile Suit Gundam RG XARX-ZERO (“Alex Zero”) is director Kenji Kamiyama’s new Gundam anime, set to air on TV starting April 2027. SOLA ANIMATION is producing, Toh EnJoe supervises the sci-fi setting, and Takeo Otsuka voices protagonist Rei Azumi. As of September 15, 2026, the broadcaster, time slot, and streaming service remain unannounced.

The game that shares its world, GUNDAM ROGUE ORBIT, launches March 5, 2027, on PS5, Xbox Series X|S, and Steam. Chronologically, the anime comes about 100 years earlier and depicts this world’s “starting point.” As for the question I posed at the top—how will Kenji Kamiyama rebuild Gundam?—the answer looks like this: make the enemy and the timeline brand-new, but keep the one core element of boys and girls on the battlefield.
