ZZZ 3.4 Banners: Robin & Kafka HSR Collab Confirmed

ZZZ 3.4 Banners: Robin and Kafka Confirmed for Honkai: Star Rail Crossover

Zenless Zone Zero Version 3.4 is shaping up to be one of the most anticipated updates yet. During the Version 3.3 Special Program, HoYoverse officially revealed that Robin and Kafka from Honkai: Star Rail will join the ZZZ roster through a collaboration event. This marks the first major crossover between the two titles, and it has immediately become the headline feature of the upcoming patch.

For players tracking latest Zenless Zone Zero updates, this confirmation ends months of speculation. However, critical details—including banner phases, combat roles, and acquisition methods—remain under wraps. Here’s a breakdown of what’s confirmed, what’s rumored, and how you can prepare.

At a Glance

• Confirmed for ZZZ 3.4: Robin and Kafka (Honkai: Star Rail collaboration)
• Expected release: December 2026 (based on current update cadence)
• Banner phases: Not stated in official materials
• Combat roles: Not stated in official materials
• Acquisition method: Not stated in official materials
• Rumored characters: Lindverne and Dracaena (unconfirmed, possibly Version 3.5)

ZZZ 3.4 Banner Overview

Both characters were revealed during the Version 3.3 Special Program. HoYoverse has not yet announced whether they will appear in separate phases, share a banner, or be obtained through event rewards.

Robin

Robin is officially joining Zenless Zone Zero through the Honkai: Star Rail collaboration. Her Attribute, Specialty, and kit remain unknown. Earlier community theories suggested she could be distributed for free during the event, but HoYoverse has not confirmed this. Players should wait for official Version 3.4 banner details before planning around a free Robin.

Kafka

Kafka is also confirmed for the crossover. Her ZZZ Attribute, Specialty, and banner schedule have not been revealed. Because Kafka is closely associated with Damage over Time gameplay in Honkai: Star Rail, some players speculate she could become an Anomaly-focused Agent in ZZZ. However, this remains Unconfirmed — subject to change.

For now, the only confirmed information is that Kafka will appear as part of the Version 3.4 crossover.

When Will ZZZ 3.4 Release?

Zenless Zone Zero Version 3.4 is expected to arrive in December 2026, based on the current update schedule. The exact release date and banner phases have not yet been officially announced. More information should be revealed closer to the Version 3.4 Special Program.

What About Lindverne and Dracaena?

Lindverne and Dracaena are currently among the characters rumored for Version 3.4. With Robin and Kafka now confirmed, they may instead appear in Version 3.5, although their exact release plans remain unclear. There is still no confirmed information about whether they will be separate playable Agents, share a special banner arrangement, or appear in a different form. Until HoYoverse releases more details, their possible Version 3.5 placement should be treated as speculation.

Should You Pull for Robin or Kafka?

If you want Kafka or Robin, Version 3.4 is now a clear saving target. We still do not know whether both characters will use limited banners or whether one may be available through the collaboration event, so keeping extra Polychromes and Encrypted Master Tapes before the official banner announcement is the safer option.

For F2P players, the priority should be to stockpile as many pulls as possible. If you’re on a 50/50, consider whether you can guarantee either character before spending. Low-spenders may want to wait for the official kit reveals to decide which character offers more value for their account.

Events & Rewards

HoYoverse has not yet detailed the Version 3.4 events or rewards. Based on previous collaborations, we can expect login bonuses, event-exclusive missions, and possibly free pulls. However, no official information is available at this time. For a look at how recent ZZZ events have been structured, see our coverage of the Signal Search Thank-You Gift event, which offered a limited outfit and currency planning advice.

Teams & Synergies

Since Robin and Kafka’s combat roles are unknown, it’s impossible to predict their team synergies. If Kafka becomes an Anomaly Agent, she could pair well with existing Anomaly units like Remielle or Aria from Version 3.1. For a deeper dive into those banners, check out our ZZZ 3.1 Remielle & Aria pull guide. Robin’s role could be anything from support to DPS, so team-building will have to wait until her kit is revealed.

Final Thoughts

The main confirmed information for the ZZZ 3.4 banners is simple: Robin and Kafka are coming through the Honkai: Star Rail collaboration. We will update this guide once HoYoverse reveals the full Version 3.4 banner lineup and character details.
