My 2026 Bangboo Tier List: Who’s the Best Ro-Buddy in ZZZ?

Let’s be real—2026 has been wild in New Eridu. The Hollows aren’t getting any friendlier, and if you’re still treating your Bangboo like a cute keychain, we need to have a little chat. These robotic companions have evolved so much since launch that I can barely recognize the tinny little helpers from two years ago. But don’t worry, I’ve been dragging my squad through every perilous Hollow the game throws at us, and I’m here to share which Bangboos actually make a dent and which ones just... squeak.

First things first—Bangboos are more than just rabbit-eared backpacks with expressive eyes. Originally designed as evacuation assistants, these little fellas now pack tech that can buff your Agents, shred Ethereals, or heal the group when you least expect it. And trust me, picking the right one feels like choosing between a loyal bulldog and a hyperactive squirrel. The difference between a well-placed S-Rank Bangboo and a B-Tier benchwarmer is night and day.

By the way, I know some of you still run around with the default Cupboo. No judgment... okay, a tiny bit of judgment. But after reading this, you’ll know exactly who deserves a spot in your lineup.

Now, onto the tier list. I’ve ranked all the major Bangboos based on their damage bonuses, team buffs, and how often they save my bacon when a boss decides to pull a surprise one-shot. Keep in mind this is early 2026—some of the newer additions from Version 2.0 are here, but the old guard still holds strong.

Here’s the breakdown:

🏆 S-Tier – The Hollow Carries

These Bangboos aren’t just strong; they actively change how you play. Slot one of these into any team, and suddenly those nasty Elite Ethereals start sweating.

• Officer Cui – I call him the “no-nonsense patrol bot.” His damage against staggered enemies is absurd, and his follow-up attacks trigger Chain reactions like nobody’s business. If you have a stun-heavy team, Officer Cui is practically an honorary Agent.

• Devilboo – This mischievous red gremlin brings unparalleled AoE chaos. His Inferno Barrage can clear mobs faster than a team of S-rank Agents on a good day. Plus, he looks like he’s always up to something, which I respect.

• Plugboo – The electric support king. Plugboo’s energy recharge buff turns your rotation into a well-oiled machine. If you’ve ever watched your ultimate bar refill mid-fight and wondered “How did that happen?,” Plugboo probably winked at you.

• Butlerboo (Ver. 2.0) – The newcomer that shook the meta. His healing and temporary ATK boost helped me clear Hollow Zero’s floor 100 without a dedicated healer. He’s a gentleman, a scholar, and a solid carry.

These S-Tier buddies are all attainable through the Selected S-Rank Bangboo banner in Signal Search, with a guarantee within 90 searches. So if you’ve been hoarding Boopons, this is your moment.

⚔️ A-Tier – The Dependable Wingmen

Not game-breaking, but absolutely worth the investment. A-Tier Bangboos fill specific niches or provide steady, reliable bonuses that can make a tough fight manageable.

• Safetyboo – The shield provider. When your Agent’s health drops, Safetyboo slaps on a protective barrier that has eaten more hits than I care to admit. Perfect for survival-focused content.

• Electroboo – Consistent electro damage and a chance to stun. Not as flashy as Devilboo, but if you need a backup stunner with decent damage, this sparkplug delivers.

• Luckyboo – The wildcard. Random buffs can make him inconsistent, but when he rolls a critical damage boost right before your ultimate... chef’s kiss. RNG-dependent players know the dopamine hit.

• Cryo-boo – Solid freeze application that pairs beautifully with ice Agents. Watching a boss shatter mid-attack sequence never gets old.

I often swap between A-Tier picks depending on the Hollow’s elemental weaknesses. They require a bit more love—higher levels, refined chips—but they’ll reward you if you’re not rushing to the S-Tier banner.

🤖 B-Tier – The Project Pals

Now, don’t take this the wrong way. B-Tier Bangboos aren’t useless; they’re just... late bloomers, or very situational. You’ll want to enhance them quite a bit before they truly shine.

• Dodgeboo – Gives a tiny evasion window extension. In theory, great for glass cannons, but in practice the timing feels more like a suggestion than a reliable buff.

• Healboo – Basic healing pulse. It’s okay for early floors, but later encounters demand burst healing or mitigation, and Healboo just can’t keep up.

• Standard Cupboo – The default buddy with a warm smile and mediocre stats. I still keep mine in the dorm for nostalgia, okay?

Here’s the kicker: the pity system in 2026 hasn’t changed drastically from earlier versions. The Selected S-Rank Bangboo banner is still your best friend. Set your target, commit to those 90 searches, and walk away with a guaranteed top-tier companion. My advice? If you’re new, aim for Officer Cui or Plugboo first—they slot into almost any composition seamlessly.

And look, I get it. The gacha nerves are real. You might pull a Luckyboo on your 50th search and wonder if you should switch targets. Don’t. Stay strong. The guarantee is too valuable to gamble on random spooks.

So there you have it—my brutally honest tier list as we dive deeper into 2026’s Hollows. The right Bangboo won’t just make your runs smoother; they’ll make you grin when that perfect buff pops at the last second. And isn’t that why we’re still playing Zenless Zone Zero? ... Well, that and the sweet satisfaction of watching a boss explode thanks to a tiny robot with an attitude.

Now go spoil your Bangboo with some new chips. They deserve it.
