Where to Watch Knights of the Zodiac Saint Seiya and Follow the Story

Navigating the Knights of the Zodiac: Saint Seiya universe can feel as daunting as climbing the steps to the Twelve Houses of Sanctuary. Created by Masami Kurumada in 1986, the franchise helped define the modern "battle shonen" genre, introducing concepts like mystical armors, constellation-based powers, and tournament arcs that influenced decades of subsequent anime. However, for modern viewers looking to jump into the series as of 2026, the landscape is notably fragmented.

Between a massive classic anime run, a controversial modern CG reboot, a recent live-action film, and a split in streaming rights across major platforms, figuring out where to start requires a bit of guidance. This comprehensive overview breaks down the different versions, explains the optimal watch orders, and details exactly where you can stream every iteration of Seiya's journey to protect the goddess Athena.

Understanding the Three Different Versions of the Franchise

When someone mentions Knights of the Zodiac today, they are usually referring to one of three distinct productions. Understanding the differences between these three pillars is the first step to navigating the franchise.

The 1986 Original Series: Produced by Toei Animation, this is the foundational text of the animated franchise. Running for 114 episodes in its initial broadcast (plus 31 later OVA episodes to conclude the story), the 1986 Saint Seiya series is widely regarded as a masterpiece of 80s animation. It features character designs by the legendary Shingo Araki and a sweeping, operatic soundtrack by Seiji Yokoyama. This version is famous for its intense melodrama, high-stakes battles, and a massive cultural footprint—particularly in Latin America, France, and Italy, where it achieved a level of popularity comparable to Dragon Ball Z.

The 2019 CG Remake: Titled Saint Seiya: Knights of the Zodiac, this is a modern 3D-animated reboot also produced by Toei Animation. It is not a sequel; rather, it is a complete retelling of the original manga's story, designed to appeal to a new generation of global viewers. The series condenses early story arcs significantly, modernizes the setting (introducing smartphones and military antagonists in the first season), and updates the visual style to full 3D computer graphics.

The 2023 Live-Action Movie: Starring Mackenyu as Seiya and featuring Hollywood veterans like Sean Bean and Famke Janssen, this feature film serves as a live-action origin story. It borrows elements from both the original manga and the 2019 CG remake, attempting to ground the mystical elements of Cosmo and the Zodiac Cloths in a slightly more realistic, modern-day setting. It is a standalone continuity separate from the animated series.

Where Can You Stream Every Version of Saint Seiya Right Now?

One of the most common frustrations for new fans is the fragmented streaming landscape. The rights to the franchise are currently split between two major platforms, creating a confusing experience for those trying to watch the modern CG remake in its entirety.

The confusion stems from a shift in production partnerships. The first season of the CG remake was heavily funded and distributed globally by Netflix. However, following the first season, the production shifted. Season 2, subtitled Battle for Sanctuary, was picked up by Crunchyroll. This means you cannot watch the entire modern series on a single platform.

For fans looking for the classic 1986 series, Crunchyroll remains the most reliable hub, hosting the original 114-episode run as well as the critically acclaimed Hades OVA chapters that conclude the story. However, availability can vary significantly by region, and the classic English dub is notoriously difficult to find on official streaming channels due to older licensing agreements.

How to Watch Knights of the Zodiac in the Right Order

Because the franchise spans nearly four decades and includes multiple timelines, spin-offs, and movies, choosing a watch order can be intimidating. According to the community consensus on r/SaintSeiya, there are two primary paths a viewer can take, depending on their tolerance for older animation and filler episodes.

The Purist Path (The 1986 Experience)

This path follows the original Toei animation run. It provides the most complete emotional journey and features the iconic soundtrack that defined the series.

1. The Sanctuary Arc (Episodes 1-73): The foundational story. It covers the Galaxian Wars, the Black Saints, the Silver Saints, and culminates in the legendary battle through the Twelve Houses of the Gold Saints.
2. The Asgard Arc (Episodes 74-99): This is technically "filler" (it does not appear in Kurumada's original manga), but it is widely considered one of the strongest filler arcs in anime history, featuring deep character development and beautiful Norse mythology integration.
3. The Poseidon Arc (Episodes 100-114): The final arc of the original 1980s television broadcast, pitting the Bronze Saints against the God of the Sea and his Mariners.
4. The Hades Chapter (31 OVA Episodes): Released in the early 2000s, these direct-to-video episodes finally adapted the concluding arc of the manga, featuring a massive leap in animation quality.

The Modernist Path (The CG Experience)

For viewers who prefer modern pacing, 3D animation, and English dubs, the CG reboot offers a streamlined alternative.

1. Season 1 (Netflix - 12 Episodes): Covers a highly condensed version of the Galaxian Wars and the Silver Saint conflicts.
2. Season 2: Battle for Sanctuary Part 1 & 2 (Crunchyroll - 24 Episodes): A more faithful adaptation of the iconic Twelve Houses arc, featuring significantly improved animation over the first season.

The "Lost Canvas" Detour: Regardless of which path you choose, many fans highly recommend watching Saint Seiya: The Lost Canvas. This 26-episode prequel series, produced by TMS Entertainment, tells the story of the previous Holy War in the 18th century. While its strict canon status is debated among purists, it stands out as a top-tier option for its darker tone, exceptional character writing, and stunning traditional animation. Unfortunately, the anime was canceled before finishing the manga's story, but it remains a beloved entry.

Key Differences Between the 1986 Original and the 2019 Remake

The decision to remake a beloved classic is always fraught with challenges, and the 2019 CG series made several bold choices that distinguish it from its 1986 predecessor. Beyond the obvious shift from traditional 2D cel animation to 3D computer graphics, the narrative structure and characterizations underwent significant alterations.

The most heavily discussed change was the gender-swapping of Andromeda Shun. In the original manga and 1986 anime, Shun is a male character who subverts traditional 80s shonen tropes; he is pacifistic, deeply empathetic, and wears pink armor, yet possesses exceptional power. In the 2019 remake, the character was changed to a female named "Shaun." According to production notes and interviews, the series writer made this change to introduce female representation into the core team of Bronze Saints. However, this decision sparked considerable backlash from long-time fans who felt that erasing a prominent, sensitive male character was counterproductive to the original story's themes.

Pacing is another major differentiator. The 1986 series took its time building the world, spending over 40 episodes on the Galaxian Wars and Silver Saint arcs before reaching the Twelve Houses. The 2019 remake condenses this entire prelude into just 12 episodes. While this eliminates filler and gets to the core action faster, some viewers feel it sacrifices the emotional weight and character bonding that made the original's later sacrifices so impactful.

A Rosetta Stone for Character Names and Terms

If you are discussing the franchise online or transitioning between different versions, you will quickly notice that characters often have two completely different names. This is a byproduct of various localization efforts aimed at making the series more accessible to Western audiences.

Much of the confusion regarding English terminology stems from an infamous early 2000s localization attempt. As discussed extensively on the Anime Superhero forums, the franchise has a complicated history with English dubbing.

"The 2003 DIC Entertainment dub of Saint Seiya is infamous among anime historians. Attempting to replicate the success of Dragon Ball Z on Cartoon Network, DIC heavily censored the show. Blood was digitally recolored blue or green to look like 'sweat' or 'energy,' violent scenes were cut entirely, and the sweeping orchestral score was replaced with a pop-punk cover of 'I Ran (So Far Away)' by Bowling for Soup. The dub was canceled after 32 episodes, leaving a lasting stigma that made official English releases difficult for years."

The modern 2019 CG series and the recent Netflix/Crunchyroll subtitles attempt to strike a middle ground, keeping the original tone intact while utilizing the localized names (like Sienna instead of Saori) to maintain consistency for newer viewers.

How the Power of Cosmo and the Zodiac Cloths Work

To understand the appeal of Knights of the Zodiac, one must understand its unique power system. Unlike other series that rely on martial arts ki or magical spells, Kurumada's universe is built on the concept of "Cosmo."

Cosmo is described as the energy of the Big Bang that resides within every human being. By tapping into this internal universe, a Saint can achieve superhuman feats, moving at the speed of sound and shattering atoms with their bare hands. The strength of a Saint is not determined by their physical musculature, but by how deeply they can burn their Cosmo.

This power is channeled through "Cloths" (often translated as Armors). According to the lore, the Goddess Athena despises weapons, so her warriors fight with their fists, protected by armors linked to the 88 constellations. The hierarchy is strict:

• Bronze Saints: The lowest rank, representing minor constellations (Pegasus, Dragon, Cygnus). They move at the speed of sound.
• Silver Saints: The middle rank, possessing greater mastery of Cosmo and moving at Mach 2 to Mach 5.
• Gold Saints: The elite guard. There are only 12, representing the signs of the Zodiac. They have mastered the "Seventh Sense," allowing them to move at the speed of light.

The most iconic arc of the franchise, the "Battle for Sanctuary," involves the five main Bronze Saints attempting the impossible: fighting their way through the 12 Houses guarded by the Gold Saints to save Athena's life. This gauntlet structure became a defining trope in anime storytelling.

What Happened to the 2023 Live-Action Movie?

In 2023, Toei Animation and Sony Pictures released a live-action adaptation titled Knights of the Zodiac. Directed by Tomasz Bagiński, the film was intended to be the launchpad for a massive six-movie franchise that would adapt the entire overarching narrative of the manga.

However, the film struggled to find its footing. According to Rotten Tomatoes data, the movie holds a 31% critic score, though audience reception was slightly warmer. Critics praised Mackenyu's physical dedication to the role of Seiya and the impressive martial arts choreography, but the film was heavily criticized for its generic script, which felt more akin to a standard YA dystopian movie than the mythic melodrama of Kurumada's work.

A major point of contention for fans was the omission of key characters. The film serves strictly as an origin story for Seiya, meaning fan-favorite Bronze Saints like Shiryu (Dragon), Hyoga (Cygnus), and Shun (Andromeda) do not appear at all. By focusing heavily on a modernized military antagonist (Vander Guraad) rather than the mystical elements of the Sanctuary, the film alienated portions of the core fanbase. Following a disappointing global box office performance, the status of the planned sequels remains highly uncertain as of 2026.

When Is the Knights of the Zodiac Season 3 and 4 Release Date?

For fans following the modern CG adaptation, the release schedule has required patience. The series has utilized a staggered release pattern since its inception.

Season 1 debuted on Netflix in July 2019. It took three years for the series to return, with Season 2 (Battle for Sanctuary Part 1) premiering on Crunchyroll in July 2022. Part 2 of the Sanctuary arc followed in April 2024, finally concluding the battle against the Gold Saints.

As of June 2026, Toei Animation has not officially confirmed the exact release date for Season 3 (which would likely adapt the Poseidon arc). However, based on the historical production cycles of the CG series—which typically require 24 to 36 months between major arc releases—industry analysts anticipate news regarding the next chapter to surface late this year or early 2027. The transition from the Sanctuary arc to the Poseidon arc requires entirely new environmental assets and character models for the Marine Generals, which accounts for the extended production time.

Pro Tips for Saint Seiya Awakening Players

Beyond the anime and films, the franchise maintains a massive presence in the mobile gaming space, primarily through Saint Seiya Awakening: Knights of the Zodiac. Developed by Tencent and published by GT Arcade, the game is a complex hero-collector RPG that requires careful resource management.

According to veteran players on the GT Arcade forums, the most critical advice for new players is the "Lock Skill Tome" rule. Skill Tomes (the blue books used to upgrade character abilities) are the most scarce and valuable resource in the game. A common beginner mistake is accidentally feeding a Skill Tome to a low-tier character or using it as standard experience fodder. Players are strongly advised to immediately lock all Skill Tomes in their inventory and reserve them exclusively for "S" or "SS" rank characters (like the Gold Saints or God Cloth variants).

Additionally, resource management regarding Advanced Gems is vital. Because the game utilizes a "pity system" for its gacha mechanics, players should avoid spending gems on standard banners. Instead, hoard Advanced Gems until a specific, meta-defining character banner is active, ensuring you have enough pulls to guarantee the character.
