Sandrone, the seventh seat of the Fatui Harbingers, is moving from concept-art legend to playable character. A wave of Version 6.7 beta material has put her splash art, idle animations, and personal namecard into circulation, alongside a redesign that's already splitting the fanbase.
What leaked for Sandrone
Three pieces of in-game art have surfaced from the 6.7 beta: a full splash illustration, a set of idle animations, and her character namecard. Together they confirm her updated outfit, color palette, and the visual motifs the playable version is built around.
The splash art presents Sandrone in a refined, gothic-mechanical silhouette, with the signature wind-up key on her back intact. A smaller mechanical figure appears behind her, but it does not match the bulky frame of Pulonia, the massive automaton fans associated with her from earlier teasers. That single detail has driven most of the community reaction since the art dropped.
Idle animations show her moving with a deliberate, doll-like cadence, leaning into the Marionette codename. Her namecard uses the same color story as the splash, with mechanical and puppetry motifs framing the central portrait.
The Pulonia question
The biggest talking point is what happened to Pulonia. In the leaked splash art, the towering automaton that many expected to fight alongside Sandrone is absent. A smaller, slimmer figure stands behind her instead, which players have interpreted as either a redesigned Pulonia or a different construct entirely.
Lore-wise, Sandrone's mechanical core was destroyed by Il Dottore during the Nod-Krai arc, and her remains were set to be returned to Fontaine for reconstruction. The playable version appears to reflect that rebuild rather than her pre-Nod-Krai form, which would explain the visual departure from her earlier appearances and from Pulonia's original scale.
Sandrone at a glance
| Detail | Leaked information |
|---|---|
| Codename | Marionette |
| Harbinger rank | Seventh of the Eleven Fatui Harbingers |
| Origin | Fontaine, created by engineer Alain Guillotin |
| Rarity | 5-star |
| Element (leaked) | Reported as Electro in earlier leaks; later beta material points to Cryo |
| Weapon (leaked) | Claymore in current beta builds |
| Companion | Pulonia (status uncertain in playable build) |
| Expected debut | Version 6.7, Phase 1 |
Element and weapon details have shifted across beta cycles, which is normal for a character this early in testing. The Cryo Claymore framing is the most recent consistent read, paired with a new reaction-focused mechanic.
The Stellar Conduct mechanic
Sandrone's kit is built around a reworked version of Superconduct. The new reaction, referred to in beta material as Stellar Conduct, layers an accumulation system on top of standard Cryo and Electro interactions.
Rapid Cryo plus Electro triggers build hidden stacks on the enemy. Once the threshold is reached, the stacks detonate into a large area-of-effect damage instance that scales off ATK as an independent multiplier. The detonation cycle is paced at roughly one trigger every several seconds, which encourages teams with fast off-field application.
Her Elemental Skill deploys a turret-style construct that fires Cryo or Electro projectiles, with a hold variant that puts her into a piloting stance with interruption resistance and heavy attacks. Her Elemental Burst clears any built-up Stellar Conduct stacks and fires a missile barrage tied to an Arkhe-style charge mechanic.
Lore context for the redesign
Sandrone was built in Fontaine by Alain Guillotin, modeled physically after his deceased sister Mary-Ann. She developed an independent AI and, after Alain's death, left Fontaine with Pulonia and joined the Fatui, eventually becoming the seventh Harbinger.
During the Nod-Krai arc, she oversaw research at the Kuuvahki Experimental Design Bureau on Paha Isle. She intervened to protect the Traveler and Columbina, and Il Dottore destroyed her core in the confrontation. Her playable debut is positioned as the result of her reconstruction, with a Vision tied to that rebuild explaining the elemental shift between earlier datamines and the current build.
Release window
No official release date has been confirmed for Sandrone. Beta material places her in Version 6.7, Phase 1, with community estimates pointing to a late June or early July 2026 window based on the standard six-week patch cycle. Treat any specific date as provisional until HoYoverse publishes the Version 6.7 livestream schedule.
Reruns expected to share the patch include Columbina in Phase 1 and Citlali alongside Raiden Shogun in Phase 2, though Phase 2 details remain incomplete in current builds.
What to watch next
The next round of beta updates should clarify three things: whether Pulonia returns in a reworked form or is replaced entirely, which element and weapon ship in the final build, and how Stellar Conduct interacts with existing Superconduct sources. A new artifact set tied to Superconduct damage and Crit Rate has also surfaced in datamines, suggesting Sandrone is the anchor for a broader reaction rework rather than a standalone unit.
Until the official reveal, the splash art, idle animations, and namecard are the clearest look yet at how the Marionette will actually play in Teyvat — and the strongest sign that a character teased since the Lazzo trailer is finally close to release.
