I’ve been playing Zenless Zone Zero long enough to treat each new anomaly unit as a small weather system rolling into the meta, and Vivian is a perfect example of that. When she debuted on April 23, 2025, in the first half of version 1.7, she didn’t just fill a roster slot; she gave ether anomaly teams another genuinely exciting option. As I revisit her in early 2026, her release still feels like HoYoverse dropping a slow-burn candle into the game, one that eventually turns into a flamethrower when you stack enough anomaly proficiency.
Who is Vivian?
Vivian is an S-rank character tied to the ether attribute and the anomaly role. She works as a member of Mockingbird, a phantom thief group operating in New Eridu alongside Hugo Vlad and the bangboo Robin. Her lore is still wrapped in secrecy, exactly like a magpie’s nest of stolen secrets, but one clear detail stands out: she is said to be a big fan of Phaethon. That playful fan-girl edge gives her a different flavor from the usual distant phantom-thief archetype.
Release Window and Roster Position
She arrived on April 23, 2025, during the first half of version 1.7. Her banner ran alongside the same patch that introduced her fellow Mockingbird member, Hugo. From a team-building perspective, her release timing mattered because anomaly characters often shift how quickly enemies melt under repeated status applications. Previous anomaly standouts such as Jane Doe and Miyabi set a high bar, and Vivian was judged against that same measuring stick.
How Vivian Plays
Vivian is an anomaly DPS, which means she doesn’t simply rely on the old rhythm of critical hits and raw attack. Instead, her value flows from racking up anomaly proficiency and triggering ether reactions consistently. I compare her fighting style to pressing a tuning fork against New Eridu’s defenses: the opening notes feel gentle, but the resonance quickly turns the entire battle into a ringing cascade of ether damage.
Best Build for Vivian
Her recommended setup is surprisingly focused.
| Category | Best Option | Notes |
|---|---|---|
| W-Engine | Flight of Fancy | Her signature weapon |
| Alternative W-Engine | Weeping Gemini | Solid substitute when you lack the signature |
| Drive Discs | 4-piece Phaethon’s Melody | Core set |
| Two-Piece Set | Chaos Jazz, Freedom Blues, or Chaotic Metal | Pick based on your squad and substats |
You’ll want plenty of anomaly proficiency rather than just chasing traditional crit stats. For me, gearing her feels less like landing a single precise shot and more like tuning a radio until the static clears. Once her anomaly stat reaches the right pitch, her ether applications stop being occasional sparks and start feeling like a weather front.
Lore and Faction Details
Mockingbird operates as a phantom thief group, so Vivian’s place in the story leans into infiltration, misdirection, and long-planned heists. We still don’t know every detail of her background, but her admiration for Phaethon adds a charming thread to her character. It also makes her interactions with the proxy world feel more personal compared with some of the colder professional agents on the roster.
Voice Actors
HoYoverse has kept her English voice actor officially unconfirmed, but her other languages are well documented.
| Language | Voice Actor | Other Recognizable Work |
|---|---|---|
| Chinese | Chen Yang | Genshin Impact’s Chiori |
| Japanese | Mizuno Saku | N/A |
| Korean | Jang Mi | Honkai Star Rail’s Silver Wolf |
This kind of multilingual casting gives Vivian slightly different tonal shading depending on which dub you use, so it’s worth sampling a few voice lines before you commit to a language pack.
Iris of the Shore Skin
Later on, Vivian received a summery skin called Iris of the Shore. The outfit puts her under a pink and blue parasol and dresses her in a dark purple and white swimsuit, which is a sharp contrast to her usual phantom-thief silhouette. The skin became available through a special limited-banner mission between versions 2.3 and 2.4: pull 180 times on limited banners and you could earn it for free. If you preferred not to grind that many pulls, the store offered it for 1,680 monochromes.
That 180-pull requirement works like an extended loyalty card. It rewards players who were already saving for multiple limited characters while gently encouraging everyone else to open their wallets. As of early 2026, this remains one of the clearest examples of Zenless Zone Zero using cosmetic rewards to sweeten a version transition.
Final Thoughts
Vivian is a stylish anomaly character who rewards patience and proper anomaly stat investment. She fits neatly into New Eridu’s larger roster of flashy utility DPS agents, but she also carries enough phantom-thief personality to stand on her own. If you’re deciding whether to build her, ask yourself two questions. Do you enjoy stacking anomaly proficiency and setting off repeated ether reactions? And do you have a solid W-Engine option ready, whether that’s her signature Flight of Fancy or Weeping Gemini? If the answer is yes, she’s still a compelling addition to an evolving account.
