TL;DR: Doom Breaker character guide, checked against AniList's own character database (media ID 136220) rather than a fan wiki: Zephyr and the second chance he never wanted, Princess Altair Cayenne, her brother Polaris and the faction he secretly leads, the angel Mercedes, and the broker hiding inside a temple sister named Anna Primrose.
Search "Doom Breaker characters" and the results split into a Fandom wiki still labeled a work in progress and scattered fan threads with inconsistent spellings. This site's Doom Breaker review covers whether the 101-chapter run earns its 8.5/10. The Doom Breaker reading guide covers where each season starts and what the hiatus means for new readers. Neither one puts a verified name and role next to every face in Zephyr's world, and neither mentions what AniList's own character data confirms about the Cayenne family's internal split.
This is that roster, built from AniList's character records rather than assembled from memory. A note before you read further: Doom Breaker's cast includes at least one relationship AniList itself flags as spoiler content. This guide states it plainly, because leaving it out would mean pretending the character data doesn't say what it says, but skip the section on the Cayenne family if you'd rather meet Polaris on the page first.
Key Takeaways
- Zephyr is AniList's sole main-cast entry for Doom Breaker: the last human still fighting when the gods abandon the world, killed by Tartarus, and sent back ten years as a slave with nothing but his memory.
- Altair Cayenne is the princess of the Kingdom of Cayenne and, per her own AniList bio, Zephyr's lover in their previous lives.
- Polaris Cayenne, Altair's own brother, is confirmed on AniList as the head of the Tartarus Worshippers, a spoiler-tagged reveal this guide states directly rather than hinting around.
- Anna Primrose, a sister at the shrine of light, doubles as the underworld broker White Rose, per AniList's bio for her.
- Ned Stryer's confirmed AniList introduction is an infiltrating Tartarus Worshipper posing as a Temple Inquisitor, not the straightforward ally some general coverage assumes.
- Tartarus (god of destruction) and Mercedes (a high-level angel) round out the divine cast, each with a distinct, non-overlapping role in the story.
- Silvestia, Eurydice, and Lucius Giornetti are confirmed supporting cast on AniList; their fuller roles aren't documented there yet, so this guide doesn't guess.
Doom Breaker Character Guide: Zephyr and the Cayenne Family
Zephyr is the only character AniList credits as series-main, and the bio is blunt about what starts the story: he's the last human fighting evil in a world the gods have abandoned to the demons. Tartarus, the god of destruction, kills him in battle. The gods who'd been watching him fight for their own entertainment decide his death shouldn't be the end, and send him back ten years, to when he was a slave rather than the strongest human alive. He keeps the memories. He keeps none of the power. Everything about the rest of this cast makes more sense once that starting point is clear: Zephyr isn't meeting most of these people for the first time. He's meeting them again, knowing things about them they haven't done yet.
Altair Cayenne is the princess of the Kingdom of Cayenne, on the continent of Aslan where the story takes place. AniList's bio for her states plainly that she was Zephyr's lover in their previous lives, and that his determination to save her this time is a driving thread in the story. That's a stronger, more specific claim than "love interest," and it reframes a lot of what Zephyr does early on: he isn't just trying to survive the ten years he's been handed back. He's trying to protect someone whose death he already lived through once.
Polaris Cayenne is Altair's eldest brother, the crown prince of Cayenne, and, separately, the youngest cardinal ever installed in the Temple of Light. Those two roles alone would make him one of the more powerful figures in Zephyr's world. AniList's bio adds a third, spoiler-tagged detail: Polaris also leads the Tartarus Worshippers, the faction built around the god who killed Zephyr in the original timeline. A prince of the kingdom housing Zephyr's previous-life love, and a cardinal of the church that's supposed to stand against Tartarus, secretly runs the organization worshipping the god responsible for the world's fall. Nothing else in Doom Breaker's confirmed cast complicates the "second chance" premise quite like this one relationship does. It's also the single biggest fact this site's existing review and reading guide leave out entirely.

Gods, Angels, and the Church of Light

Tartarus is the god of destruction and the reason any of this is happening. He kills Zephyr in the opening chapters, after the other gods have already written humanity off. The same battle later becomes the gods' justification for sending Zephyr back: they found it entertaining enough to grant him a second life, purely for their own amusement, not out of mercy. That framing matters. Doom Breaker never lets Zephyr's second chance read as a gift from a benevolent source, and Tartarus is the fixed point the whole regression revolves around.
Mercedes is credited on AniList as a high-level angel, the representative who shares the words of the gods. She's a messenger figure rather than a combatant or a romantic thread, distinct from Altair and separate from the Church of Light's human hierarchy that Polaris climbs through. Her role is narrower than most of the named cast here, and AniList's own database doesn't expand much beyond that one-line function. It's still worth knowing, because a story with this many titled human factions benefits from having at least one confirmed divine figure who isn't secretly working an angle.
Anna Primrose is a sister at the shrine of light on paper. AniList's bio confirms a second identity underneath that role: she operates as White Rose, an underworld broker who trades in monster corpses, equipment, and information about people. Readers of this site's Doom Breaker review will recognize the surface version of her already, the nun who cheerfully suggests Zephyr sell his organs when he runs short of options. AniList's character data is what actually connects that dark-comedy figure to the Anna Primrose name and the broker business behind it, a link the earlier coverage on this site doesn't make explicit.

Return of the Blossoming Blade runs a similar regression premise through a murim family instead of a divine-and-royal one, worth comparing against how differently the two series handle a protagonist rebuilding trust from scratch.

Allies, Agents, and the Rest of the Confirmed Cast
Ned Stryer is where this guide has to depart from how the series' cast gets described elsewhere. AniList's confirmed introduction for him is specific: an official disciple of Jinryang of the East, and the 9th-highest-ranking member of the Tartarus Worshippers. He works under Mathias Grimmer, the 36th-highest-ranking member of the same faction, and both of them infiltrate the Temple of Light disguised as Inquisitors to hide what they're actually doing there. That's an antagonist-faction introduction by any reasonable reading, not the "expanding ensemble around Zephyr" framing that some general coverage of Season 2 uses. Whether he later shifts allegiance is the kind of thing a long-running story can absolutely do, but nothing in AniList's current data confirms that shift, so this guide isn't going to assume one.
Silvestia, Eurydice, and Lucius Giornetti are all confirmed supporting characters in AniList's records for Doom Breaker, and that's honestly most of what can be said about them with confidence right now. AniList lists an alternative name for Silvestia ("Queen of Elves") but doesn't provide a fuller character bio for any of the three. That's a real gap, not a small one, and it's worth being upfront about rather than padding out their entries with details borrowed from a fan wiki that can't be independently checked against the manga itself. This is also roughly where the AniList character database for Doom Breaker currently stops: nine named entries total for a story that's been running since 2022, which tells you something about how far behind the site's coverage is relative to a more mainstream series like Solo Leveling, where AniList's cast data runs far deeper.
That's the complete verified Doom Breaker character list as AniList's database currently has it documented, and it's noticeably shorter than what a Fandom wiki or a TV Tropes character index would hand you. Readers who want more series built around a similar dark, cost-driven regression instead of a wider cast rundown have options in the manhwa like Doom Breaker recommendations, sorted by whether the mechanic, the tone, or the action is what drew you in.
Step-by-Step
A short process for using this roster without spoiling yourself further than you want to be.
1. Read the Zephyr summary first. Everything else on this page assumes you already know why he's starting over: killed by Tartarus, sent back ten years, no power, no allies who recognize him yet.
2. Treat a title as an organization, not a moral signal. "Cardinal," "Inquisitor," and "disciple" describe rank inside Doom Breaker's factions. Polaris Cayenne's cardinal title and Ned Stryer's Inquisitor cover both sit right next to a very different confirmed loyalty.
3. Keep family lines and faction lines in separate columns mentally. The Cayenne royals and the Tartarus Worshippers overlap in ways a character's first scene doesn't telegraph.
4. Respect the spoiler tags AniList itself uses. Polaris Cayenne's fuller role is flagged that way in the source data for a reason. This guide states it once, clearly, rather than repeating it in every section.
5. Match spellings against this guide before trusting a search result. It's Cayenne, not Kayenne. Silvestia, not the "Sylvestia" spelling a fan wiki uses.
6. Use the reading guide for when, and this guide for who. The Doom Breaker reading guide maps the two seasons by chapter range. This page exists to answer a narrower question about identity and allegiance, not sequence.
Doom Breaker Character Guide: Names Worth Getting Right
A handful of names in this cast get flattened, misspelled, or quietly conflated in fast recaps. Here's how to keep them straight.
Cheongdam and Blue-Deep are the same person. AniList's staff credit lists "Cheong-Dam" under the role of story and art; the Fandom wiki and the official WEBTOON credit both render the same name as Blue-Deep. Doom Breaker is a solo project: one creator writes and draws the whole series, which is unusual at this level of production polish for a WEBTOON Original.
Altair and Polaris Cayenne are siblings, not a couple, and not interchangeable. Altair is the princess and Zephyr's previous-life lover. Polaris is her older brother, the crown prince and a cardinal, and, per AniList, the Tartarus Worshippers' actual leader. Getting the two confused erases the exact family tension that makes this cast worth mapping in the first place.
Silvestia, listed under that spelling on AniList, appears as "Sylvestia" on the Doom Breaker Fandom wiki. This guide uses AniList's spelling throughout, since it's the source this guide traces every name back to.
Ned Stryer and Mathias Grimmer aren't equals despite both posing as Inquisitors. Stryer is the 9th-highest-ranking Tartarus Worshipper; Grimmer, who he answers to, ranks 36th. The numbers run backward from what you'd expect at a glance, since Stryer outranks the man he ostensibly reports to within the Temple's cover structure, which is exactly the kind of detail a fast recap tends to drop.
Tips for Reading This Cast

Track this roster by relationship first, faction rank second. A name's weight in a given chapter usually comes down to who they're related to or loyal to, not how senior their title sounds. Polaris outranks almost everyone in the Church of Light on paper. His confirmed faction loyalty matters more to the story than that rank does.
Don't assume every character introduced as part of "Zephyr's growing circle" in general coverage is actually on his side by the time you meet them. Ned Stryer is the clearest example here: his confirmed AniList introduction places him inside the organization responsible for killing Zephyr in the first place, not among his allies. It's possible the story moves him somewhere else later. It's also possible some existing coverage of Season 2's wider cast simply blurred an infiltrator into the ensemble he was infiltrating. Either way, this guide sticks to what AniList's character data confirms rather than assuming a redemption arc that hasn't been verified anywhere.
Watch Polaris Cayenne specifically once his role starts becoming clear on the page. A prince, a cardinal, and the secret head of the faction that worships the god who ended the world once already: that's a lot of weight riding on one confirmed character entry, and it's the single most consequential relationship this roster documents.

Frequently Asked Questions
Who is the protagonist of Doom Breaker?
Zephyr, AniList's sole main-cast entry for the series. He's the last human still fighting after the gods abandon the world to the demons, killed in battle by Tartarus, and sent ten years into the past as a second chance he never asked for.
Who is Altair Cayenne in Doom Breaker?
The princess of the Kingdom of Cayenne on the continent of Aslan, and, per AniList's own bio for her, Zephyr's lover in their previous lives. Zephyr's determination to save her this time around is one of the story's central emotional threads.
Is Polaris Cayenne a villain in Doom Breaker?
AniList's character database confirms Polaris, Altair's own eldest brother and the youngest cardinal in the Temple of Light, also leads the Tartarus Worshippers, the faction devoted to the god who kills Zephyr. AniList flags this as spoiler content, so treat it as a late-story reveal rather than an early-chapter fact.
Who is White Rose in Doom Breaker?
White Rose is the alias used by Anna Primrose, a sister at the shrine of light by day. AniList's bio confirms her second identity as an underworld broker who trades in monster corpses, equipment, and information, the same character this site's review describes suggesting Zephyr sell his organs.
Is Ned Stryer an ally or an enemy in Doom Breaker?
AniList introduces him as a disciple of Jinryang of the East and the 9th-highest-ranking Tartarus Worshipper, working under Mathias Grimmer while both pose as Inquisitors inside the Temple of Light. That's a confirmed antagonist-faction introduction, not the straightforward ally framing some general coverage of the series' ensemble implies.
Who is Tartarus in Doom Breaker?
The god of destruction. Tartarus kills Zephyr in the opening chapters after the other gods abandon humanity to the demons, and it's that same battle the gods later use as their excuse to send Zephyr back ten years, since they found watching him fight entertaining.
Who is Mercedes in Doom Breaker?
A high-level angel credited on AniList as the representative who shares the words of the gods with Zephyr. She's a divine messenger figure, not a combatant or a romantic interest, distinct from Altair and from the Church of Light's human hierarchy.
Is this Doom Breaker character guide based on a fan wiki?
No. Every name and role in this guide traces back to AniList's character database for the manga entry (media ID 136220), checked live, cross-referenced against the official WEBTOON series page. Where AniList doesn't yet have a bio for a character, this guide says so instead of filling the gap with a fan wiki's version.
