In the dazzling, danger-filled avenues of New Eridu, survival is never a solo affair. By 2026, players of HoYoverse’s urban fantasy ARPG Zenless Zone Zero have learned that the diminutive, rabbit-eared companions known as Bangboo are far more than mascots. These artificial intelligences pack an astonishing array of combat utilities, from summoning localized black holes to generating life-saving shields. Each Bangboo brings a distinct personality and skill set, capable of tipping the balance in the most chaotic Hollow raids. Whether you’re assembling a team around Elemental Anomalies or looking to maximize burst damage, understanding their roles is now an essential part of high-level play.

What Are Bangboo?

Bangboo are autonomous combat robots that accompany Proxy-led squads into the Hollows. Unlike Agents, they cannot be directly controlled; instead, each Combat Bangboo operates on its own logic, automatically activating its Active Skill when conditions are met. They also contribute to the squad’s Chain Attack sequence, triggering a unique Bangboo Chain Attack that does not consume one of the regular Chain Attack slots. This means a Bangboo effectively adds a free, high-impact finisher to any chain combo, often inflicting massive Elemental buildup or area damage.

Beyond their immediate firepower, Bangboo are defined by their Additional Ability—a passive effect that scales with your team composition. These abilities range from doubling Anomaly Buildup when two or more Agents of a matching Attribute are present, to generating energy for off-field characters or providing shields based on the number of enemies hit. This synergy system rewards players who carefully align their Agent lineup with the selected Bangboo, creating layered strategic depth.

Maximizing Your Squad with Bangboo Synergies

Selecting the right Bangboo is as crucial as picking your Agents. A team built around Ice Anomaly, for example, gains immense value from Sharkboo or Penguinboo, effectively doubling the pace at which Freeze triggers. Meanwhile, a Cunning Hares-themed team with Amillion secures a Chain Attack that scales inversely with enemy count—devastating against elite single targets. Support-oriented teams will favor Exploreboo or Avocaboo to keep Energy flowing and HP topped off, while Defense squads rely on Paperboo’s taunt and shielding to redirect pressure.

Remember that Bangboo Chain Attacks do not consume standard chain slots; they add an extra, often heavily buffed, strike. This feature alone makes them a permanent fixture in endgame content like Shiyu Defense and the Hollow Zero raids. As of 2026, even newer Bangboo variants continue to follow this design philosophy, rewarding players who master the intricate web of Attributes, Factions, and Agent roles.

The streets of New Eridu are ever-evolving, but with a well-chosen Bangboo at your side, you turn chaos into opportunity. Experiment with different combinations, study the faction and element synergies, and let your mechanical companion elevate your Proxy journey to new heights.
