Ultraman Zero is officially confirmed for two September episodes of Ultraman Teo: Episodes 11 and 12. Tsuburaya Productions announced the guest appearance and confirmed Mamoru Miyano as Zero's voice. For viewers who want to follow the series without going beyond the official synopses, the key dates are straightforward: Episode 11 is listed for September 19, 2026, while Episode 12 is listed on the official page for September 25.
Tsuburaya also states that Ultraman Teo normally airs in Japan on Saturdays at 9:00 a.m. JST, with same-period worldwide distribution in multiple languages. There is therefore a scheduling discrepancy around Episode 12: September 25, 2026 falls on a Friday. Because the official sources checked do not separately confirm an exceptional day change, the safest approach is to treat September 25 as the date currently published by Tsuburaya and recheck the official channel close to release, rather than automatically moving the episode to September 26.
Which September episodes feature Ultraman Zero?
| Date listed by Tsuburaya | Episode | Ultraman Zero | Official information without extra spoilers |
|---|---|---|---|
| September 5 | 9 — “The Static Reach” | Not announced | Continues Teo and Pucchi's confrontation with Volthog. |
| September 12 | 10 — “Let’s Go to Training Camp!” | Not announced | The Astronomy Club goes on a training camp while Ibuki's past returns to focus. |
| September 19 | 11 — “The Mysterious Boy” | Yes | Tsuburaya announces Zero's appearance and Mamoru Miyano as guest voice cast. |
| September 25 | 12 — “A Hero’s Determination” | Yes | The official synopsis highlights Zero's battles and his challenge to Ibuki's determination. |
This schedule comes from Tsuburaya Productions' official September episode announcement: ULTRAMAN TEO September Episode Synopses and Stills Revealed.
What to expect from Episode 11, without going beyond the official synopsis
In Episode 11, “The Mysterious Boy,” Tsuburaya directly confirms that Ultraman Zero appears. Mamoru Miyano is credited as the character's guest voice actor. The synopsis involves the Astronomy Club, a kaiju alert and a mysterious boy who surprises Ibuki. It also points to increasing pressure on the group over Pucchi.
For spoiler-conscious viewers, that is enough context: the episode marks Zero's entry into Teo's story, and the official page does not suggest that viewers need a separate crossover arc to understand the appearance.
What to expect from Episode 12
Episode 12, “A Hero’s Determination,” keeps Zero in the story. The official preview emphasizes his combat ability and a conversation that puts Ibuki's willingness to fight under scrutiny. At the same time, the Astronomy Club must think about how to protect Pucchi.
Tsuburaya again credits Mamoru Miyano as Ultraman Zero. The published synopsis does not reveal how the conflict ends or Ibuki's final answer, so there is no need to go further to understand Zero's basic role in the episode.
Why the September 25 date deserves a second check
Two pieces of information published by Tsuburaya do not line up perfectly: the September preview lists Episode 12 for September 25, 2026, while the series outline says the regular broadcast slot is Saturday, 9:00–9:30 a.m. JST. September 25, 2026 is a Friday.
Without a specific official notice explaining the difference, it would be misleading to label the date an error or replace it with September 26. For planning, use September 25 as the currently published date and check the official Tsuburaya YouTube guide or the official Ultraman YouTube channel during release week.
Where to watch Ultraman Teo officially
Tsuburaya says the series is distributed worldwide in the same period as its Japanese broadcast and in multiple languages. For viewers outside Japan, the most direct official place to check is the Ultraman Official YouTube Channel. Tsuburaya's official channel guide features Ultraman Teo with Japanese and English audio tracks and multiple subtitles.
In Japan, the official platform list includes TVer, Net-mo-Tele-Tokyo, TSUBURAYA IMAGINATION and the official Ultraman YouTube channel. Linear broadcast is carried by the TV Tokyo network and affiliated stations. The broader distribution details are in Tsuburaya's Global Broadcast & Streaming Information.
Availability, upload time and how long each episode remains accessible can vary, so the best practice is to check the official channel on the episode date rather than rely on unofficial reuploads or third-party calendars.
How to find Zero's episodes without using unofficial uploads
- Start with the official Ultraman channel and search for Ultraman Teo.
- Use the YouTube ULTRAMAN Channel Guide to check the current official programming.
- Look for Episodes 11 and 12 rather than videos that only put “Ultraman Zero” in the title.
- Verify that the upload comes from Tsuburaya's official channel before watching or sharing it.
- For Episode 12, check the date again near release because of the September 25 versus regular Saturday-schedule discrepancy.
Why Ultraman Zero's appearance matters
Zero is one of the most recognizable Ultra Heroes of the franchise's modern era. Tsuburaya's own encyclopedia records his debut in 2009's Mega Monster Battle Ultra Galaxy: The Movie and his connection to Ultraseven. In Ultraman Teo, the September preview positions his appearance at a point where Ibuki is being challenged to think about what it means to fight and protect.
For this guide, the important distinction is between confirmation and expectation: Zero is officially announced for Episodes 11 and 12; any details about battle outcomes, consequences or appearances beyond those episodes should not be treated as confirmed without new information from Tsuburaya.
Quick viewing guide
