A surprise crossover between Zenless Zone Zero and Honkai Star Rail has officially arrived, bringing a piece of the Astral Express to the streets of New Eridu. While the collaboration was not previously announced, players can now find Honkai Star Rail’s conductor, Pom-Pom, appearing within the video store.
Quick Facts
- Event Status: Active now in Zenless Zone Zero.
- Key Character: Pom-Pom, the conductor of the Astral Express, appears in-game on Sixth Street.
- Next Update: Additional details are scheduled for Winter 2026.
The event allows players to interact with Pom-Pom in the video store, who initially arrives seeking help to locate a comic book. Following this interaction, the character moves around Sixth Street, giving players the opportunity to track them down for further dialogue.
Is This the Start of More Crossover Content?
The appearance of Pom-Pom has sparked community speculation regarding the future of this partnership. While unofficial leaks have suggested the potential for characters to jump between the two rosters—specifically pointing to Honkai Star Rail's Robin joining Zenless Zone Zero—these claims remain unconfirmed. HoYoverse has not released an official statement regarding playable crossover characters at this time.
The event also raises questions about the connectivity of HoYoverse's shared universe. With Genshin Impact's gliders previously spotted on the Herta Space Station, the arrival of Pom-Pom in New Eridu continues a pattern of subtle nods between the titles. However, the logistics of the Astral Express reaching a location like New Eridu remain a mystery, as there are no known train stations in the game capable of hosting the massive vessel.
For those looking to participate, keep an eye on official Zenless Zone Zero social channels for updates arriving in Winter 2026. In the meantime, players are encouraged to manage their current Honkai Star Rail and Zenless Zone Zero codes to ensure they are prepared for any future event-related rewards.
