ZZZ Bangboo Tier List — Which Bangboos Rule (And Which Are Just Cute Sidekicks)
Hey fellow Proxy. If you’ve been diving into Zenless Zone Zero (ZZZ) lately, you know those little robo‑buddies called “Bangboos” are more than just fluff — they can seriously shift how your runs go. I’ve been messing around with pretty much every Bangboo you can get, testing them in multiple content types (Hollows, Deep Dive, general exploration), and over time I learned which ones straight‑up crush it, which are “meh but usable,” and which… well, are mostly for fun.
Below is my personal, updated tier list — with reasoning, caveats, and a bit of in‑the‑trenches advice. Think of this as both a friendly guide and a bit of insider opinion from someone who's played a ton.

I. Introduction to Zenless Zone Zero Bangboos
A. Game Overview: Free‑to‑Play Action RPG
Zenless Zone Zero is Hoyoverse’s fresh spin on action RPGs — a game where you (the Proxy) assemble a squad of three Agents + one Bangboo companion, dive into dangerous Hollows (or other content), and fight, explore, loot, and survive.
Bangboos are unique to ZZZ: little sentient (well — intelligent‑device) companions originally built for evacuation assistance in New Eridu, but now heavily used for combat and support when raiding Hollows.
B. Bangboo System: Companion Mechanics
Combat Bangboos: These fight alongside your Agents. They have their own stats (HP, ATK, DEF, Impact) and skills — including active skills, passive buffs, and even join‑in on Chain Attacks.
Support Bangboos (Hollow‑Zero mode): Provide buffs/debuffs or utility, rather than dealing direct damage.
Bangboos are obtained via a separate “Bangboo Channel” gacha (Signal Search), using a special currency (Boopons) — which is earnable via gameplay (not purely pay‑to‑win).
Once you get duplicates, they turn into Bangboo Cores (or Logic Cores), used to upgrade/ascend the Bangboo — boosting stats and scaling buffs.
C. Importance of Bangboo Selection
Your Bangboo isn’t just “cute cosmetic” — picking the right one matters. Some are heavy‑hitting DPS‑style, others support energy, some help with anomaly buildup (for Element/Anomaly‑based teams), some buff crowd control, and some are simply reliable all‑rounders. Choosing “wrong” can make runs more annoying or inefficient; choosing “right” can smooth out the hardest content.
D. Tier List Purpose and Methodology
My tier classification comes from a mix of:
Bangboo base stats & how well they scale with upgrades
How broadly useful they are (content, team types, endgame viability)
Ease of use — some require specific team comps, some don’t
Performance consistency: are they flaky or reliable run after run
I ranked them from Tier 0 (top dogs / elite) down to Tier 3 (sub‑par / niche / early‑game only).
E. Version 2.5 Current Meta Update
With the latest patches (as of late 2025), a few Bangboos got buffed, while team composition and anomaly‑based mechanics got more stable. That means some previously “just okay” ones now feel more useful, and the meta for what’s “top” has shifted slightly. This tier list reflects that current state.
II. Tier Classification System Overview
Here’s how I categorize Bangboos:
| Tier | What It Means |
|---|---|
| Tier 0 | Elite — strong damage or support, shine in endgame content, great default pick for many teams |
| Tier 1 | Very good — reliable support or DPS, works in most content, requires little optimization |
| Tier 2 | Conditional — solid if paired with right Agents / team comp, or situationally useful |
| Tier 3 | Sub‑par / early‑game / niche — may be okay early on, but limited long-term utility / narrow usage |
In some guides I saw labels like “S / A / B / C” — I correspond roughly to those, but with a bit more nuance for endgame viability and team flexibility.
III. Tier 0 Bangboos: The Elite Tier
These are my go‑to picks if I want to clear high‑difficulty Hollows, push late‑game content, or just minimize headache.
Amillion — The Physical Powerhouse
Known as one of the strongest “base” Bangboos. High ATK and Impact stats, and specializes in physical damage output.
Great for early AND late game — even if your Agents are relatively modest.
Simple to use, doesn’t demand complicated synergy: if you want raw DPS, this is your safest bet.
Verdict: Always a safe pick, especially for newer or budget‑oriented accounts.
Plugboo — Electric Anomaly Dealer / General Damage Specialist
Strong stats + electric/anomaly specialization (works well with Electric‑element Agents or teams built around that).
Electric being a common element in many Agents helps — increasing chance your team benefits from anomaly synergy.
Great for consistent damage output and versatile enough for many team comps.
Verdict: My personal “go-to” if I’m building a new team — flexible and reliable.
Safety (Safetyboo) — Heavy‑Hit Physical / Balanced Bangboo
Historically labelled S‑rank in many community tier‑lists.
Has balanced stats and synergy with Physical‑type / Belobog‑affiliated teams — good mix of offense and reliability.
Less “flashy” than some anomaly‑specialists, but often performs with very low effort.
Verdict: Excellent “safe pick” for a physical‑heavy party, especially mid‑ to late‑game.
Resonaboo — Ether / Crowd‑Control / Utility Specialist
Focuses less on brute damage, more on utility: crowd control, anomaly buildup (for Ether‑type builds), situational control.
Great for teams that rely on anomaly effects, status control, or those that need backup beyond raw ATK.
More specialized (less “plug‑and‑play”), but with right team can be game-changing.
Verdict: Go‑to choice if you run Ether‑heavy agents or need utility/CC for tougher dungeons.
Sharkboo — Ice Anomaly / Element‑Specialist
Strong choice if you have (or plan to) Ice‑element Agents. Ice anomaly buildup / damage makes him potent in those teams.
Less flexible in mixed or non-Ice teams — but in mono‑Ice or anomaly‑focused comps he shines.
Verdict: Specialist: great for Ice teams, not super useful otherwise. Requires some planning.
Butler — Energy Support & Sustainability Expert
Not all Bangboos are damage dealers. Butler provides energy regeneration / resource support — super valuable in longer runs or energy‑dependent builds.
Helps characters rely less on their own energy generation and smoothens rotations, especially in content where energy cost matters.
Verdict: Great support pick for stamina‑heavy or resource‑hungry Agents; potentially overlooked but underrated.
IV. Tier 1 Bangboos: Reliable Options
These are reliable, often flexible, and can perform solidly — but may require a bit more team synergy or have narrower niche than Tier 0.
Robin — Versatile Damage Dealer / Flex Support
Deals physical and ether damage depending on comp. Has useful effects like Daze application + anomaly buildup (if aligned). Good for hybrid builds or flexible teams.
Useful for players who switch up Agents often or don’t stick to strict element/role lock.
Verdict: A “jack‑of‑all‑trades” — not the strongest, but dependable and easy to slot in most comps.
Belion — Physical AoE & Crowd Control Utility
AoE physical damage + crowd‑control potential makes Belion a solid choice against groups of enemies or when dealing with many trash mobs.
Good synergy with “AoE‑heavy” or crowd‑clear type Agents.
Verdict: Great for farming, mob‑heavy Hollows, or clearing trash before boss fights.
Officer Cui — Follow‑Up / Burst Support Specialist
Offers follow-up attacks and buffs to chain‑attacks with certain team compositions or conditions. Has its niche especially in burst‑heavy or timing‑based strategies.
Verdict: For players who like more tactical or burst‑based play; a bit more “micro‑management” but rewarding.
Red Moccus — Tank/CC‑Type Physical Bangboo
Deals decent physical damage and offers crowd control / enemy positioning support (stuns, knockbacks, etc.), especially helpful if you have tanky or defense‑reliant Agents.
Verdict: Good for teams relying on control or needing enemy disruption; not always “top‑dps,” but supportive.
Agent Gulliver — Electric Piercer / Utility Electric Bangboo
Electric‑type damage with pierce mechanics; versatile across many team types; works well with electric or hybrid comps.
Verdict: Solid “all‑rounder,” especially if you don’t want to build around one strict element.
Miss Esme — Healing / Support‑Focused Bangboo
More support‑oriented: provides HP restoration, energy regen, or buff support — useful in long fights, survival content, or lower‑gear runs.
Verdict: Good choice if you're still building Agents or want an easier time in tanky or sustainability‑heavy content.
Snap — Dodge Counter / Assist‑Specialist Support Bangboo
Offers buffs when dodging/countering, and supports assist rotations — especially helpful in dodge‑heavy or evasive builds.
Verdict: Niche but useful in agile or avoidance‑based comps, or when you rely on quick rotations.
V. Tier 2 Bangboos: Situational Use / Conditional Utility
These Bangboos aren’t “bad,” but they often require very specific team setups or are only helpful in certain scenarios — meaning they’re probably not your first choice for casual or mixed-content runs.
Rocketboo — Fire AoE Specialist
Deals fire-based AoE damage; useful if you have a mono‑fire or fire‑heavy team. However, fire enemies and resistances can limit its use.
Verdict: Fun in the right team, but too situational for general use.
Bangvolver — Physical Anomaly Buildup / Burst Bangboo
Focused on anomaly buildup + physical damage; decent if your Agents emphasize anomaly mechanics, but risk (or payoff) is high.
Verdict: Use only if your team is built around anomaly chaining or burst damage; otherwise performance may be mediocre.
Baddieboo / Brawlerboo / Cryboo (Fire‑specialist Bangboos)
Fire‑based roles, homing missiles, AoE, but generally weaker than elite picks — limited by fire‑resistant enemies and less universal utility.
Verdict: Niche, maybe fun for variety — but expect inconsistency.
Knightboo — Ether Buff / Support (Weak‑moderate)
Offers party-wide buffs, but buff durations/conditions may limit value; useful only in specific builds or content.
Verdict: Maybe a decent support for light‑focused comps, but overall underwhelming compared to top‑tier supports.
Booressure / Electroboo / Exploreboo / Penguinboo / Devilboo / Magnetiboo (Utility / Specialty / Utility‑Trade Bangboos)
These offer certain buffs, specialty effects, or anomaly bonuses — sometimes interesting if you like experimenting or just want “fun.”
But their performance tends to be inconsistent, weaker overall, or too niche for serious progression.
Verdict: More “fun or mid‑tier experiment” than serious team‑building tools. Use if you enjoy variety or don’t have better options yet.
VI. Tier 3 Bangboos: Early‑Game or Niche‑Only
If you’re just starting ZZZ or don’t have many Bangboos, these are “okay-ish,” but they’ll fall off once you get better options. Think of them as fallback or filler until you “get serious.”
Bagboo — Starter Bangboo
Often your first Bangboo (free/guaranteed) — provides basic support, small buffs, nothing exceptional.
Good enough to get you through early content, but will struggle in harder Hollows or higher‑tier content.
Verdict: Acceptable starter partner — but plan for replacement ASAP.
Paperboo / Boollseye / Cryboo / Sumoboo / Magnetiboo (Various Utility / Off‑Meta Roles)
Some offer shield, taunt, random buffs, or utility mechanics. Occasionally useful for very niche content or for fun runs — but lack consistent offensive power or broad utility.
Verdict: Use only if you have no better Bangboo, or want to experiment — don’t rely on them for serious progression.
VII. Faction, Element & Team Synergy — Key Considerations
One big lesson I learned: Bangboo choice doesn’t exist in isolation. To maximize their value, you should consider:
Agent team composition — element type, anomaly‑type synergy, physical vs anomaly damage focus
Bangboo faction / faction bonuses — some Bangboos perform better with certain Agent factions or party compositions.
Content type — boss runs, high‑difficulty Hollows, group mobs, anomaly‑focused challenges — different Bangboos excel in different scenarios
Upgrade / investment level — a top‑tier Bangboo at low level might underperform vs a mid‑tier Bangboo properly upgraded with cores or stat investment
Because of that, sometimes a “Tier 1” Bangboo might outperform a “Tier 0” in a poorly composed team — always evaluate synergy over raw rank.
VIII. Beginner-Friendly Bangboo Picks & Early‑Game Strategy
If you’re just starting ZZZ (or don’t have many resources yet), here’s what I’d recommend right now:
Amillion — best all‑round start, physical, easy to use, no weird conditions.
Plugboo — great if you plan on Electric or mixed builds; flexible enough for most early‑mid game.
Safety (Safetyboo) — balanced pick, decent in many content types; safe fallback.
Bagboo — use as a placeholder until you pull something better.
As soon as you get Boopons and do Signal Search, aim to get a top‑tier Bangboo (S‑rank) — the S‑rank selector guarantees your chosen S-rank once you hit it.
Upgrade when possible (Bangboo Cores + system upgrades) — because scaling matters: a fully-upgraded Bangboo often outshines an underleveled “better” one.
IX. Endgame & Hard Content — When You Need “Real Allies”
Once you're approaching harder Hollows, Deep Dive stages, or high‑difficulty content:
Prioritize Tier 0 Bangboos — their damage or utility tends to matter more than ever.
Build team synergy carefully — for example, pairing anomaly‑heavy Agents with anomaly‑specialist Bangboos like Plugboo or Sharkboo.
Have fallback/support Bangboos for sustain or energy management (like Butler) — especially in long fights.
Don’t underestimate the value of flexibility — having a few good Bangboos vs just one “meta” pick helps adapt to different content types.
X. Why Some Bangboos Are Overrated — And Common Pitfalls
I’ve seen some new players always chase the “cute” or “popular” Bangboos — sometimes with disappointing results. Common mistakes:
Ignoring team composition / element synergy — slapping a “good” Bangboo on a mismatched Agent team.
Under‑upgrading / under‑investing — leaving your Bangboo underleveled, so you don’t get their full potential.
Not considering content requirements — e.g. using a fire‑specialist Bangboo when enemy resistances or mechanics make fire weak.
Chasing rare but niche Bangboos while ignoring stable, reliable picks.
Remember — a practical, flexible Bangboo that fits your team is better than a “top” Bangboo on paper that doesn’t sync.
XI. My Final Verdict: Bangboo Tier Summary & Recommendations
Top Recommendations
Amillion — Best all‑rounder, especially early to mid‑game, scalable, physical DPS‑oriented.
Plugboo — Electric / anomaly‑specialist, very flexible and strong for many team builds.
Safety — Balanced physical Bangboo, reliable and easy to slot.
Resonaboo — For utility / anomaly / control‑focused builds (especially Ether‑heavy).
Other Good Picks (Situational / Team‑Dependent)
Robin, Belion, Officer Cui, Red Moccus, Agent Gulliver, Miss Esme, Snap — each good for specific approaches: burst, utility, healing, crowd control, etc.
Butler — underrated energy support — worth grabbing if you play longer runs or resource‑heavy content.
Use with Caution / Only Early‑Game / Niche
Bagboo, Paperboo, Cryboo, Magnetiboo, Exploreboo, etc. — fine early on or for fun, but you’ll likely replace them when you get better.
Fire‑only / very niche specialty Bangboos (e.g. some B-rank ones) — only worth using if you build around them and accept the trade‑offs.
XII. Wrapping Up — Use Bangboos as Tools, Not Bling
At the end of the day: Bangboos are tools to augment your team, smooth out runs, or amplify certain playstyles. They shouldn’t just be collectible “cute companions.”
If you’re new: start simple — aim for a flexible, easy‑to‑use Bangboo like Amillion or Plugboo. As you grow: build around synergy (element, faction, team roles), invest in upgrades, and diversify your Bangboo roster for different content.
If you’re a veteran or aiming for endgame: assemble 2–3 “meta‑ready” Bangboos (damage, utility/support, anomaly‑specialist) to cover all bases — because ZZZ can throw all kinds of challenges at you.
Most importantly: have fun. Some Bangboos are goofy, some are serious tools; some will carry you through tough runs, some will make you chuckle as they flail beside you. That mixture — plus smart choices — is what keeps ZZZ fun and rewarding.
If you want — I can build 3 fully optimized “team + Bangboo” comps (early, mid, late game) that I think are currently meta‑strong. Could help if you want a ready‑made plan. Want me to sketch those out for you now
