In the wasteland city of New Eridu in Zenless Zone Zero, a group of mechanical lifeforms, no taller than an adult’s knee, is making a unique mark on the entire game world—these are the Bangboo. With their rabbit-like ears and adorable “enn enn” sounds, these intelligent machines serve not only as cute mascots scattered throughout the streets but also as indispensable fourth combat units. From auxiliary tools for navigating Hollows to versatile intelligent lifeforms, the evolution of Bangboo reflects a vision of a future where humans and machines coexist.
1. From Disaster Warning to Urban Steward: The Birth and Evolution of Bangboo
The creation of Bangboo stemmed from New Eridu’s survival needs against Hollow disasters. When abnormal spaces suddenly emerged to devour parts of the city, these mechanical lifeforms, equipped with disaster-reception systems, would instantly sound alarms and guide residents to safety through built-in navigation. The first-generation Bangboo, designed by Madam “Sunbringer” (CEO of the f Marcel Group), featured rabbit-like ears and an encrypted communication method known as “Bangboo-speak.” Using their signature “enn enn” onomatopoeic sounds to convey information, they became a reassuring presence in times of crisis.
As technology advanced, Bangboo gradually evolved beyond single-purpose functions: construction-type Bangboo were equipped with two independent component slots for installing wide-area collection modules; household Bangboo featured customizable voice functions; while exploration models designed for Hollow expeditions came with Ethereal-sensing alarms and a one-second rapid map upload system. The latest model, the Belobog HP-601C, boasts 16 outfit variations and four customizable module slots, and even integrates a “Radish” chip capable of plotting the optimal escape route. This fusion of survival intelligence and mechanical aesthetics has cemented Bangboo as a true symbol of New Eridu’s technological culture.
2. Emotional Resonance of Mechanical Life: From Tools to Companions
The charm of Bangboo lies in their vivid character design. Each Bangboo has its own unique personality:
Safety is a talkative engineer: Belobog Heavy’s engineering Bangboo constantly complains that its drill is jammed, yet in crucial moments, it uses its demolition drill to break through the battlefield.
Eous suffers from charging anxiety: this abandoned Bangboo sneaks off to recharge in the middle of the night, and its backstory unveils the deep mentor-student bond between the Phaethon siblings.
Golden Bangboo is a money-obsessed guardian: these stray Bangboo, corrupted by the Hollows, frantically hoard Gear Coins, sometimes sparking treasure rushes among Hollow Raiders.
The game strengthens this emotional connection through fine-tuned details: when a Bangboo’s power runs low, its ears flash red and it emits urgent “ne-mm” sounds; players can trigger special dialogues through touch interactions, and certain models may even “crash” if petted too much. Many Proxies surely dream of having an adorable Bangboo companion by their side. HoYoverse has even released Bangboo Plushie blind box, which not only recreate their in-game cuteness but also add the thrill of collectible surprises. Their appearance resembles Labubu, leading many players to joke that Zenless Zone Zero now has its very own “Bangbubu.”
3. Adorable Firepower in Battle: The Strategic Value of the Fourth Combat Unit
In Zenless Zone Zero’s combat system, Bangboo transcend the traditional concept of pets to become true strategic assets. Players can control three Agents alongside one Bangboo, forming a “3+1” combat matrix. These mechanical partners unleash imaginative attacks: Rocketboo charges forward riding a rocket to trigger an explosion, Sharkboo deploys homing torpedo traps, while Amillion wields a Portable Machine Gun that delivers piercing physical damage.
The core value of Bangboo lies in their buff system:
Attribute Charge Specialists: For example, Resonaboo’s “Mini Black Hole” continuously pulls in enemies and accumulates Ether anomaly value. Once an enemy’s Daze bar is maxed, it triggers high elemental damage. This mechanic is especially critical in mid-to-late-game elite battles, where enemies under Daze take multiple times the normal damage.
Faction Synergy Hubs: Faction-specific Bangboo can boost Chain Attack multipliers under certain conditions. For instance, when a team includes two Cunning Hares members, Amillion’s Chain Attack damage can increase by up to 45%. Combined with Nicole’s defense penetration and Von Lycaon’s finisher damage, this synergy forms a devastating strike chain.
Functional Support Units: Butler’s “Tea Break” restores Energy to on-field characters, Aero Boo generates Ether Bubbles that recharge both front-line and back-line characters, while Exploreboo’s modified scanner randomly grants healing, shields, or auto energy regeneration.
This design breaks the mold of conventional support roles, turning Bangboo into flexible tactical modules. Data shows that high-star A-rank Bangboo reach stats on par with S-rank models at three stars. For example, Knightboo’s energy regeneration efficiency even surpasses some S-rank units. This “underdog surpassing the elite” system greatly enriches team-building strategies.
4. Building a Cultural Symbol: Extending from Game to Reality
Bangboo have transcended the boundaries of the virtual world to become one of Zenless Zone Zero’s cultural icons:
Official Merchandise: Inspired by the fan meme “Plans Have Changed,” Zenless Zone Zero released Waifei Peninsula–style phone cases. In addition, Bangboo Garden Kingdom blind box combine Bangboo designs with fruits and vegetables, creating a quirky surprise. Players eagerly shared their “Veggieboo” collections across social media.
Fan Creations: On Bilibili, content creators drew speculative Bangboo anatomy charts based on in-game schematics, sparking amusing debates about whether they were “solid and unbreakable.”
Real-World Tech Parallels: Bangboo charging stations have been humorously nicknamed “mechanical butt-chargers” by players. This tongue-in-cheek interpretation of new energy facilities reflects how young people today approach and reimagine technology in daily life.
Cross-Franchise Connections: Fans often compare Bangboo to Pom-Pom, the train conductor from Honkai: Star Rail, even spinning crossover stories featuring Madam Twilight and the Stellaron Hunters.
Strolling down Sixth Street, you might encounter a Little Dinnieboo fundraising batteries for the Cat Brothers. In battle, Bangboo will unhesitatingly support you. And in everyday life, their round, adorable forms can be found in every corner of New Eridu.
