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. As of April 2026, the game features both S-rank and A-rank Bangboo, 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.

S-rank vs A-rank Bangboo: is the rarity gap real?
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. Player feedback consistently highlights certain Bangboo that perform above their rarity tier, with Eous, Twentie, Six, and Officer Cui (also listed as Officer Cudi in some player discussions) frequently mentioned as top performers in community tier rankings.
Which Bangboo should you prioritize?
A few Bangboo consistently earn praise across different team types based on player feedback and performance data:
Officer Cui appears repeatedly in player rankings as a top-tier pick, earning recognition in both official S-rank listings and fan-created tier lists. Butler also draws consistent positive attention, with players 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:
- 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.
