Zenless Zone Zero Best of S-Rank Bangboos

Introduction to Zenless Zone Zero Best of S-Rank Bangboos

In Zenless Zone Zero, Bangboo are more than just mechanical mascots—they are essential allies on the battlefield. These quirky, robot-like companions function as support units that actively and passively contribute to your team’s performance. Every Bangboo is equipped with a distinct skillset, consisting of an Active Skill, a Passive Ability, and, in many cases, a Chain Attack Skill. Each of these elements plays a critical role in combat and can tip the scales in your favor when used strategically.

The Active Skill is automatically triggered during battle, typically operating on a cooldown timer. These skills vary between Bangboo and can deal damage, provide buffs, or even debuff enemies depending on the type of Bangboo deployed. Passive Abilities are often dependent on your current team composition and can enhance specific attributes like damage output, energy regeneration, or elemental effects, adding a strategic layer to team building. For example, some Bangboo offer synergy bonuses when paired with Agents of a matching faction or attribute type, making it beneficial to coordinate your team around your chosen Bangboo.

Perhaps the most powerful tool in a Bangboo’s arsenal is the Chain Attack Skill. These skills can be triggered during a QTE (Quick Time Event) chain attack, unleashing a potent blow without consuming one of your Agents’ action opportunities. This makes them especially valuable in high-pressure scenarios, where maximizing every turn counts. However, not all Bangboo are capable of performing chain attacks. This trait is often limited to combat-oriented or higher-ranked Bangboo, while some A-Rank support variants may forgo this feature in exchange for stronger passive or active utility effects.

Choosing the right Bangboo to accompany your Agents is crucial for optimizing your team’s effectiveness. Their unique abilities allow you to tailor your strategy for different combat scenarios—whether you need burst damage, sustained buffs, or additional crowd control, there’s likely a Bangboo to fit the role. As you progress through the game and unlock more Bangboo options, experimenting with different combinations can lead to surprisingly powerful synergies and team compositions.

Understanding S-Rank Bangboos

Just like Agents in Zenless Zone Zero, Bangboo come with their own set of stats and progression mechanics that directly impact their performance in combat. Each Bangboo has core attributes including Attack, HP, and Impact, with some potentially featuring a PEN Ratio—a stat that affects how much of an enemy’s defense they can ignore. As you level up a Bangboo, their base stats such as attack, HP, and defense increase, enhancing their overall combat utility and survivability.

Additionally, Bangboo can be ascended at key level milestones—specifically at levels 20, 30, 40, 50, and 60. Each ascension not only raises their level cap but also improves critical stats, including critical rate and skill multipliers for both their active skill and chain attack, significantly boosting their damage potential and effectiveness in battle.

Upgrading a Bangboo is relatively straightforward and revolves around two core resources: Widgets and Fluid. Widgets are the primary material used for leveling up Bangboo, and they can be earned from a variety of sources such as Hollow Zero explorations, daily commissions, and purchases via Bang Bucks, which are obtained through Bangboo summons. Since Hollow Zero exploration is not limited by stamina, it is generally more efficient to farm Widgets there rather than using Bang Bucks to buy them directly.

Fluid, which is required for ascension, is primarily obtained by increasing your Hollow Zero license level, completing weekly Bounty commissions, and from Hollow Zero rewards. Additionally, Fluid can be bought in unlimited quantities at the convenience store using the Widgets you’ve farmed, allowing players who consistently engage with Hollow Zero to fully max out their Bangboo over time without relying heavily on premium resources.

With 28 Bangboo available as of January 29, 2025, the roster offers more variety than the number of Agents at that point, making it essential to understand their roles to build effective teams. Bangboo can be categorized into several functional archetypes: pure damage dealers, pure support units, anomaly buildup specialists, and hybrids like damage with utility or damage with support.

Understanding the specific function of each Bangboo allows you to better synergize them with your Agent lineup, maximizing efficiency in various combat scenarios. For early progression, it’s advisable to invest in two Bangboo—one for each squad you plan to use in dual-team content like Shiyu Defense. This ensures that both of your teams are supported by capable Bangboo, making it easier to handle more difficult endgame content as you advance.

Best of All S-Rank Bangboos and Their Details

Agent Gulliver is an S-Rank Bangboo that excels in Electric DMG and rapid Electric Anomaly Buildup, making it a powerful support option for teams focused on triggering Shock status effects. Its Active Skill, Emergency Operation, unleashes three piercing electric attacks, which not only deal consistent damage but also contribute significantly to building up Electric Anomaly on targets. This makes it an excellent choice for quickly applying Shock, especially when paired with other Electric-focused Agents.

Gulliver’s Additional Ability, Bangboo Assault Squad, greatly increases its effectiveness when synergized with specific team compositions. If your squad includes two or more Hollow Special Operations Section 6 (HSOS6) members, Gulliver gains a 30% boost to its active skill and chain attack damage when hitting enemies afflicted with Shock. This incentivizes team building around the HSOS6 faction to maximize Gulliver’s damage output. Additionally, when targeting enemies suffering from non-Electric Anomalies, Gulliver benefits from a 60% increase in Anomaly Buildup, allowing it to rapidly transition the status effect into Electric Shock, especially useful in mixed-element teams where multiple types of Anomalies are applied.

Its Chain Attack, Assault Time, is a high-impact piercing electric strike that delivers massive Electric Anomaly Buildup, further reinforcing its role as a key enabler for Shock-based strategies. This makes Gulliver a versatile asset in Electric compositions, where triggering and maintaining Shock effects can lead to amplified damage from both Agents and other Bangboo effects.

Gulliver performs best when integrated into squads that can reliably apply or benefit from Electric Anomalies, leveraging both its raw electric output and supportive buildup scaling. Its ability to adapt to enemy status and faction synergy makes it a flexible and potent addition to teams aiming to dominate through rapid anomaly application and consistent burst windows.

Amillion is an S-Rank Bangboo specializing in Physical DMG and is designed to deliver sustained firepower through rapid, multi-hit attacks. Its Active Skill, Portable Machine Gun – Debt-Clearer, deploys a mini turret that continuously fires bullets at enemies, dealing consistent Physical damage over a short duration. This skill excels in maintaining offensive pressure but does not contribute to Daze or Physical Anomaly Buildup, making it more suited for raw DPS support rather than crowd control or debuff application.

Its Additional Ability, Street Code, enhances Amillion’s value in faction-specific compositions. When your squad includes two or more Cunning Hares characters, Amillion gains a significant Bangboo Chain Attack DMG boost of up to 45%, with the bonus scaling higher when fewer enemies are present on the field. This makes it particularly effective in single-target scenarios, such as elite or boss fights, where its sustained damage can be fully utilized without dilution across multiple targets.

Amillion’s Chain Attack, Portable Machine Gun – Gatling Debt-Clearer, ramps up the firepower with a combination of machine gun and cannon fire, dealing a prolonged burst of Physical DMG. This chain attack is ideal for burning down high-priority targets, especially when synergized with Cunning Hares Agents who can help trigger the Bangboo’s passive bonuses. The emphasis on continuous damage and high chain attack output positions Amillion as a valuable asset in Physically-oriented or faction-synergized squads, particularly when aiming to maximize single-target burst potential.

While it lacks utility in terms of Anomaly Buildup or control effects, Amillion shines in roles that prioritize pure damage throughput, especially in tightly coordinated team compositions. Its effectiveness scales with the quality of synergy around it, making it a strong pick for players looking to optimize Physical-focused squads or exploit the Cunning Hares faction bonuses.

Butler is an S-Rank Bangboo designed with a support-first approach, offering reliable energy regeneration alongside modest offensive capabilities. Its Active Skill, Tea Break, summons a snack that provides Energy to the receiving Agent, allowing for faster access to powerful EX Special Attacks. While the raw energy gain may not be massive in isolation, the ability to steadily restore energy across combat makes Butler a highly universal support option, fitting into a wide variety of team compositions that rely on frequent skill rotations or burst windows.

Its Additional Ability, Personal Butler, enhances this support role further by granting an extra 20% Energy generation when the squad includes two or more Victoria Housekeeping Co. characters. This synergy makes Butler particularly effective in teams built around factional consistency, enabling smoother ability uptime for key characters and reinforcing a strong support loop that sustains momentum in battle. The passive’s condition encourages thoughtful team building to fully unlock Butler’s potential, especially in content where energy economy plays a critical role in success.

Butler’s Chain Attack, Afternoon Dessert, uses whimsical visuals—striking with a frying pan and pancakes—to deliver ranged Physical DMG. While its offensive output is not high compared to other Bangboo, it compensates with a notably low chain time, allowing it to slot quickly into chain sequences and maintain combat flow without delaying higher-damage follow-ups from Agents. This makes Butler a non-intrusive support pick for chain-heavy strategies.

Though not designed for raw damage, Butler excels in keeping your team’s skills ready to fire, especially when paired with Victoria Housekeeping Co. Agents like Ellen, Lyon, or Reena. Its energy utility, short chain duration, and faction-based synergy make it an ideal support Bangboo for teams that value consistency, uptime, and smooth skill cycling over raw offensive stats.

Resonaboo is an S-Rank Bangboo that excels in applying Ether DMG and rapidly building Ether Anomaly, making it a valuable pick for teams centered around Ether-based disruption and crowd control. Its Active Skill, Mini-Black Hole, creates a gravitational field that pulls in nearby enemies while dealing continuous Ether DMG. This skill is especially effective against clustered enemies, allowing your team to control the battlefield while layering on consistent damage and Anomaly buildup. The pulling effect not only groups enemies for easier combos but also supports Agents who benefit from tight formations for AoE attacks.

Resonaboo’s Additional Ability, Radiations Effect, enhances its synergy in Ether-centric teams. When your squad contains two or more Ether Attribute characters, its Bangboo Chain Attack inflicts 100% more Anomaly Buildup, accelerating the process of triggering Ether Anomaly effects, such as spatial disruption or Ether Collapse. This makes Resonaboo ideal for enabling teams that rely on stacking Anomalies for burst or control.

Its Bangboo Chain Attack, Primordial Black Hole, unleashes a powerful Ether-based strike, likely building on its gravitational theme to deliver heavy damage and Anomaly buildup across a wide area. This chain attack complements its active skill by reinforcing its AoE control focus, making it especially potent in scenarios with multiple enemies on the field.

With strong Ether-based utility and field manipulation, Resonaboo is best suited for compositions that can consistently apply or capitalize on Ether Anomalies, such as teams featuring Nicole or Zhu Yuan. It thrives in encounters where enemies group together, offering both damage and setup opportunities. Although its effectiveness may scale with the availability of Ether characters, its core mechanics remain impactful in both general and specialized team setups.

Several S-Rank Bangboo in Zenless Zone Zero serve highly specialized roles, each aligning with specific elemental or factional synergies to enhance your team’s combat efficiency. Safety is a Physical DMG-oriented Bangboo that becomes even more effective when paired with Belobog Heavy Industries characters, reinforcing its damage potential through factional synergy. Sharkboo, on the other hand, thrives in Ice-based teams, delivering consistent Ice DMG and substantial Ice Anomaly Buildup, especially when supported by multiple Ice characters to trigger enhanced effects.

Rocketboo specializes in Fire DMG, making it a natural fit for Fire Attribute lineups that benefit from sustained burn effects and burst-oriented chain attacks. Similarly, Bangvolver contributes high Physical DMG and gains increased Anomaly Buildup when deployed with other Physical Attribute Agents, allowing for more frequent control effects like Daze. Red Moccus also deals Physical DMG, but its unique trait lies in its synergy with Sons of Calydon characters, reinforcing its power in faction-aligned squads. Plugboo rounds out the list with a focus on Electric DMG and Electric Anomaly Buildup, making it ideal for teams centered around applying Shock or accelerating Electric reactions.

Choosing the Right S-Rank Bangboo: Importance of Team Synergy

Choosing the right Bangboo often hinges on your team composition and future build direction. Many Bangboo gain significant bonuses when paired with two characters of a matching Attribute, making them particularly well-suited for mono-element teams that aim to maximize Anomaly triggers or benefit from unified damage types. Others, like Butler, offer more universal utility—providing Energy regeneration that fits a wider variety of squads, especially those that include Victoria Housekeeping Co. characters but don’t rely as heavily on elemental synergy.

While S-Rank Bangboo tend to offer stronger base stats and more impactful chain attacks, several A-Rank Bangboo hold their own by offering unique utility or easily activated additional abilities. Their flexibility can make them strong contenders in content where support, sustainability, or simple synergy is more valuable than raw numbers. Additionally, increasing a Bangboo’s star level by obtaining duplicates significantly enhances their effectiveness by improving skill multipliers and overall stat growth—making consistent investment an important part of Bangboo progression and optimization.
