Honkai Star Rail will launch an assured HSR × ZZZ crossover in winter 2026, a claim solidified during a 4.5 special broadcast.
Hoyoverse officially confirmed that content and characters will be shared, meaning HSR characters will appear in Zenless Zone Zero while characters from ZZZ will gain access to HSR.
The partnership will mirror the earlier HSR × Honkai Impact 3rd event, where only the Impact series gained an HSR character and HSR received none.
Leaks indicate that Robin from HSR will join Zenless Zone Zero, while Astra Yao and Ellen are set for the HSR roster.
ZZZ had already started the alliance by adding Pom‑Pom as a Bangboo within the game.
Players should refill Stellar Jades and Polychrome by using the new codes from both HSR and ZZZ.
The release is expected in December, close to the holidays, and could align with either an HSR 4.8 or 5.0 update, depending on the scheduling choice.
The cross‑game collaboration promises a fresh mix of talents and a holiday flavour across both universes.
