HoYoverse has a weird obsession with making us fall in love with literal appliances. First, it was the Pompom-esque mascots of the past, but in Zenless Zone Zero, they went all in on the Bangboo. Among the sea of round, rabbit-eared mechanical assistants, one specific unit has been popping up in every high-level discussion lately: Sweety Zenless Zone Zero fans know as the dedicated support for the PubSec squad.
It’s small. It’s pink. It looks like it belongs in a candy shop rather than a hollow infested with Ethereals. But don't let the aesthetics fool you.
If you’ve been grinding Shiyu Defense or trying to push through the latest Withering Garden intensity levels, you know that team synergy isn't just about your S-Rank agents. It’s about the little guy floating behind them. Sweety (officially designated as the Officer Cui companion in some circles, but widely recognized by its "Sweety" moniker in specific regional localized events) isn't just a cosmetic choice. It’s a tactical powerhouse.
What Actually Makes Sweety Zenless Zone Zero Teams Better?
Most players make the mistake of picking a Bangboo based on rarity alone. They see an S-Rank and think, "Yeah, that'll do." That is a massive mistake.
Sweety is fundamentally built around the Physical and Anomaly mechanics. While Bangboo like Amillion or Sharkboo get all the glory for their raw DPS output, Sweety provides a level of consistency that’s hard to replicate. When you’re running a team centered around Zhu Yuan or Qingyi—basically the Criminal Investigation Special Response Team—this Bangboo becomes a force multiplier.

The chain attack is where the magic happens.
Most Bangboo just do a bit of chip damage. Sweety, however, applies a significant amount of Anomaly buildup. In the current 2026 meta, where Daze and Anomaly application are the two pillars of clearing content under the time limit, having an extra source of Physical buildup is life-saving. It's the difference between a boss recovering its posture and you getting that final, satisfying Shatter proc.
The Synergy Problem Most Players Ignore
Let’s be real. You’ve probably tried to slap Sweety onto a Fire or Electric team because you liked the animations. Stop doing that. It’s hurting your clear times.
To unlock the passive "Social Butterfly" (or its equivalent localized trait), you need to have specific team compositions. Usually, this means having at least two agents from the same faction or element. For Sweety, the sweet spot is the PubSec faction.
Think about how Zhu Yuan plays. She’s a burst-heavy Ether DPS who relies on getting the enemy into a Stunned state to dump her shells. If Sweety is proc-ing extra damage or helping keep the pressure on while Zhu Yuan is reloading or switching, the flow of combat stays fluid.
Real Numbers: Why the Community Is Obsessed
Data miners and frame-counters over at the ZZZ dedicated forums have spent hours dissecting the Bangboo's internal cooldowns. Honestly, it’s a bit overkill, but the results are clear. Sweety has one of the fastest animation cycles for its active skill.
Why does a fast animation matter? Because in Zenless Zone Zero, the camera and the targeting system can get messy when too much is happening. A Bangboo that gets in, does its job, and gets out without blocking your view of an incoming "yellow flash" parry signal is worth its weight in Polychrome.
- Active Skill: Throws a series of "treats" that explode on contact.
- Anomaly Rate: Roughly 15% higher than the generic A-Rank combat Boo.
- F2P Accessibility: Unlike the limited S-Rank Bangboo that require specialized vouchers, Sweety is often more attainable for the average player.
It's just efficient.
The "Cute Factor" vs. Practicality
There is a segment of the player base that refuses to use Sweety because it looks "too soft." These are likely the same people struggling to get an S-Rating on the harder Shiyu Defense floors.
In New Eridu, aesthetics are a trap.
The "Sweety" aesthetic is actually a clever bit of world-building by HoYoverse. These Bangboo are designed to be integrated into civilian life, which is why they look like mascot characters. But the lore tells us that Hollow Raiders often mod these units with black-market tech. When you upgrade your Sweety Bangboo, you aren't just making it "cuter"—you’re effectively overclocking its logic core to handle the chaotic data of a Zero Hollow.
Common Misconceptions About Sweety
I see this all the time on Reddit: "Sweety is just a worse version of Butler."
No. Just... no.

Butler is an Energy Generation god. If you need energy, you use Butler. But if your team is already energy-efficient and you’re hitting a wall because the enemy's physical resistance is too high, Sweety is the answer. It’s about utility, not just raw stats.
Another big myth is that Sweety's damage scales with the Agent’s attack. In reality, Bangboo damage is largely determined by their own level and the "Bangboo Talent" upgrades you feed them at the workbench in the back of Random Play. If you haven't been visiting Enzo to tune your Bangboo, you’re leaving about 20% of your potential damage on the table.
How to Maximize Sweety in Your Current Rotation
If you’re going to commit to using this unit, you need to change how you think about your switch-ins.
- Lead with a Stunner: Get that daze bar up to about 80%.
- Trigger the Bangboo Chain: Ensure Sweety is the one helping bridge the gap between your Stunner and your Main DPS.
- Capitalize on the Debuff: Sweety often leaves a lingering effect that increases the impact of the next few hits. Use your EX Special Move immediately after the Bangboo finishes its animation.
It sounds simple, but the timing is tight. You’ve got to be precise.
Is It Worth the Investment?
If you are a casual player who just wants to clear the story, you can use whatever Bangboo you want. Pick the one that makes the funniest noise. But if you’re looking at the endgame—the "Hollow Zero" high-intensity runs—then yes, Sweety is a mandatory part of a physical-leaning toolkit.
The resource cost to level a Bangboo to 60 is steep. You need those specialized "Bangboo Algorithm" chips. Don't spread yourself too thin. Focus on one S-Rank for your primary team and Sweety for your secondary PubSec or Physical team.
The Future of Sweety in Zenless Zone Zero
As the game moves into the 2.0 and 3.0 patches, power creep is inevitable. We’ve already seen it with the newer agents. However, the Bangboo system is surprisingly resilient. Because they are tied to factions, as long as New Eridu keeps introducing characters associated with the police or general city maintenance, Sweety will have a place in the roster.

It’s one of the few units that feels "future-proof" because its value isn't tied to a single number, but to the way it interacts with the Anomaly system.
Your Tactical Checklist for Sweety
To get the most out of your Sweety Bangboo, you should immediately check your current setup against these three pillars of performance.
Verify Faction Synergy
Check your Agent screen. If you aren't seeing the "Bangboo Combo" light up in the bottom corner of your team UI, you're wasting the slot. Sweety requires a specific synergy to trigger its secondary passive. If you're running a mixed elemental team without a faction anchor, switch to a more generic Bangboo like Bagboo until you can stabilize your roster.
Optimize the Workbench
Go to Enzo’s shop in Sixth Street. Many players forget that Bangboo have their own "equipment" path. Ensure you’ve maxed out the "Anomaly Application" nodes first. Raw HP or Defense for a Bangboo is useless—they can't die, so why build them like tanks? Focus entirely on Attack and Anomaly Rate to ensure every time Sweety jumps into the fray, it’s actually contributing to the stun phase.
Master the Chain Attack Order
In the settings menu, you can actually toggle the "Manual Chain Attack" option. This is huge. Instead of letting the game pick which Bangboo or Agent comes next, you can manually select Sweety when you need that specific Physical proc. It takes practice to hit the right button under pressure, but it's the only way to play optimally in the late-game Shiyu Defense floors.
