What exactly is a Bangboo in Zenless Zone Zero?
Bangboo are small companion units that join your team in Zenless Zone Zero, operating through a mix of active and passive skills to support your three-character squad. They sit outside your main roster but contribute to combat in meaningful ways, making your choice of Bangboo a genuine strategic decision rather than a cosmetic one. According to the ZenlessLab Bangboo list (last updated April 16, 2026), there are currently both S-rank and A-rank Bangboo in the game, each with distinct roles and skill sets.

How do Bangboo skills work?
Every Bangboo brings two layers of contribution to your team: an active skill that triggers during combat and a passive skill that runs in the background. The active skill fires at set intervals or under specific conditions, while the passive provides a constant stat bonus or team-wide effect. Choosing the right Bangboo means matching both layers to your team composition and playstyle.
Always check both the active and passive skills before committing to a Bangboo. A unit with a strong active but a passive that doesn't fit your team is often worse than a simpler Bangboo that syncs with your characters on both fronts.

S-rank Bangboo at a glance
S-rank vs A-rank Bangboo: is the rarity gap real?
The short answer is: it depends on your team. S-rank Bangboo tend to have higher base stats and more impactful active skills, but several A-rank options are competitive when paired with the right characters. The community on HoYoLAB has been vocal about certain Bangboo punching above their rarity, with users specifically calling out Eous, Twentie, Six, and Officer Cui (also listed as Officer Cudi in community discussions) as standout S-tier performers based on personal rankings.
Community tier lists for Bangboo are based on personal preference and team synergy rather than hard DPS benchmarks. Use them as a starting point, not a rulebook.
Which Bangboo should you prioritize?
Based on available community data from HoYoLAB discussions and the ZenlessLab roster, a few Bangboo consistently earn praise across different team types:
Officer Cui gets mentioned repeatedly in community rankings as a top-tier pick, appearing in both the official ZenlessLab S-rank list and HoYoLAB fan tier lists. Butler also draws consistent positive attention, with community members specifically highlighting it as a standout S-rank. For players running electric-focused teams, Electroboo offers a competitive A-rank alternative that doesn't require chasing S-rank pulls.
Here's a practical priority framework based on available information:
- Check whether any S-rank Bangboo directly matches your main team's element or faction.
- If no strong match exists at S-rank, an A-rank Bangboo with the right passive can outperform a mismatched S-rank.
- Resonaboo and Rocketboo are worth considering as general-purpose S-rank options if you don't have a specialized pick yet.
Avoid picking a Bangboo purely based on rarity. An S-rank Bangboo whose active skill doesn't align with your team's rotation timing can waste its own potential entirely.
