Mobile Suit Gundam RG: XARX-ZERO, pronounced “RG Alex Zero”, places anti-war ideas at the centre of a new science-fiction story. Director Kenji Kamiyama understands that message may feel especially direct against today’s global conflicts, but he believes the franchise’s characters can still encourage empathy and hope.
The story follows Ray Azumi, an orphan chosen to pilot the next-generation mobile suit Gundam ZERO. After humanity enjoys a period of prosperity and expansion throughout the solar system, a hostile silicon-based lifeform known as Apocalypse forces people to abandon Earth.
A new timeline for Gundam
Revealed at San Diego Comic-Con in July, XARX-ZERO sits outside the Universal Century, the franchise’s main continuity. Kamiyama brings experience from science-fiction productions including Ghost in the Shell: Stand Alone Complex and Star Wars: Visions, while his long-standing connection to Gundam helped inspire his career in anime.
The project carries the difficult task of respecting a nearly 50-year-old franchise while offering something unfamiliar. Producer Yasufumi Kohashi said executive producer Naohiro Ogata wanted a “hardcore sci-fi world” that had not previously been explored in Gundam. Kohashi also recalled seeing a message on franchise creator Yoshiyuki Tomino’s desk: “You have to break taboos to create something new.” That idea gave Kamiyama room to push the series into new territory.
The unusual title follows the playful reading approach used by the 2025 series GQuuuuuuX. Kamiyama explained that “Alex Zero” began as a way to signal a completely new timeline. “RX” is also the codename associated with Gundam, making the name a piece of wordplay and a personal rethinking of what Gundam can be.
Why the anti-war message still matters
Kamiyama sees war as Gundam’s central subject, with an explicitly anti-war message. He is doubtful that animation alone can stop a real conflict, yet he has given the characters the responsibility of carrying hope through the story.
His aim is to show people who might bridge the deep divisions between opposing extremes. By encouraging empathy, the characters may offer a small contribution to discussions affecting Japan and the wider world.
Another important idea is that the past cannot be changed. However, people can choose constructive actions in the future. Kamiyama hopes those actions can alter how the past is understood and the influence it continues to have.

Meeting expectations while breaking them
Working inside an established franchise brings an unusual creative tension. Existing fans have expectations and may already hold firm ideas about what the series should deliver. Kamiyama believes a new entry must satisfy those expectations while also surprising viewers enough to challenge them.
Original productions present a different problem. Developing a story from nothing allows creators to test ideas and imagine fresh surprises, but it also means beginning without an established foundation. Kamiyama described that process as exhilarating and difficult.
XARX-ZERO combines both challenges: it belongs to a famous franchise, yet introduces a new setting and story. Kamiyama joked that this made the production effectively twice as demanding.
Human conflict inside a science-fiction world
Kamiyama believes Gundam endures because it combines war with an examination of humanity. He also joked that the mobile suit’s deliberately “cool face” is part of its appeal, but his serious answer focused on human nature and conflict.
Mobile suits are weapons, and the franchise repeatedly asks how humans develop new ways to fight with advanced technology. Although the setting is fantastical, the creators provide scientific explanations for how its machines operate. That grounding distinguishes Gundam from many other robot anime series and helps explain why its machines are treated as mobile suits rather than simply robots.

The tradition of the Char-type rival
Kamiyama did not reveal the design, appearance or personality of XARX-ZERO’s Char-like character. He did confirm that the role remains important to the story.
A Char-type figure functions as both villain and rival to the protagonist. The character reflects the main hero, acting as a mirror image while continuing one of the franchise’s most recognisable storytelling traditions.
That combination of familiar elements and deliberate reinvention defines XARX-ZERO: a new universe built around the enduring Gundam concerns of war, technology, human nature and the possibility of hope.
