Koleda Belobog: The Tiny Terror of Stun in Zenless Zone Zero (2026 Guide)

In the chaotic world of Zenless Zone Zero, where giant robots and ethereal horrors run amok, one agent proves that size isn't everything. Koleda Belobog, the pint-sized president of Belobog Industries, wields a hammer that's roughly the size of her entire body. She's an S-rank Fire agent who specializes in stunning enemies into next week, and she does it with a delightful mix of ferocity and adorable rage. As of 2026, she remains a premier Stun DPS—or "Breaker" if you prefer the technical term. Her job? Smash, daze, and let her teammates clean up the mess. And with her trusty bear companion Ben by her side, she's an absolute menace.

The Hammer of Belobog: Koleda's Kit 🐻🔨

Koleda's playstyle is all about slow, deliberate attacks that build up massive daze. She's not a speedster; she's a wrecking ball. Her unique mechanic, Furnace Fire, activates after using an EX Special Attack or Ultimate. This turns her basic attacks into enhanced fire attacks, adding insult to injury. When paired with Ben, her basic, special, and ultimate attacks get a damage and daze boost, so keeping them together is a no-brainer. Seriously, they're a package deal—like peanut butter and jelly, but with more explosions.

Her high impact stat and daze multipliers make her a natural stun agent. The goal is to stun enemies, trigger chain attacks, and let your main DPS go to town while the enemy is helpless. It's a beautiful cycle of violence.

W-Engines: The Best Tools for Smashing ⚙️

Choosing the right W-Engine for Koleda is like choosing the right hammer for a demolition job. You want impact, energy, and maybe a little fire. Here are the top picks:

• Hellfire Gears (S-Rank): Her signature engine. When off-field, it boosts energy regen. After an EX Special, it increases Impact by 10-20% for 10 seconds, stacking twice. Since Koleda spams EX Specials, she easily gets both stacks, making her an even better stun agent.

• The Restrained (S-Rank): Hitting enemies increases Basic Attack DMG and Daze by 6-12% for 8 seconds, stacking up to 5 times. This is fantastic if Ben is on the squad, turning Koleda's basic attacks into a daze-generating machine.

• Six Shooter (A-Rank): Gains a Charge stack every 3 seconds, up to 6. Using an EX Special consumes all stacks, each increasing Daze by 4-6.4%. Perfect for a quick rotation where Koleda pops in, uses EX, and swaps out.

Disc Drives: Dressing for Success 👗

There are two main builds for Koleda: one focused on pure stun, and one that lets her deal respectable damage. Both are viable depending on your team composition.

Build 1: The Stun Machine

• 4-Piece Shockstar Disco: 2-piece gives +6% Impact. 4-piece makes Basic, Dash, and Dodge Counter attacks inflict 20% more Daze.

• 2-Piece Swing Jazz: +20% Energy Regen.

Main Stats: IV. CRIT Rate% or CRIT DMG | V. Fire DMG | VI. Impact

Sub Stats Priority: 1. ATK% | 2. Crit Rate, Crit DMG | 3. Anomaly Proficiency

This build maximizes daze and gives enough energy to trigger Furnace Fire often.

Build 2: The Fiery DPS

• 4-Piece Inferno Metal: 2-piece +10% Fire DMG. 4-piece: Hitting a Burning enemy increases CRIT Rate by 28% for 8 seconds.

• 2-Piece Swing Jazz: +20% Energy Regen.

Main Stats: IV. CRIT Rate% or CRIT DMG | V. Fire DMG | VI. Impact or Attack

Sub Stats Priority: 1. CRIT DMG | 2. ATK% | 3. CRIT Rate | 4. Anomaly Proficiency

This build is for when you want Koleda to hit harder. Pair her with another agent who applies Burn, then switch to Koleda for a crit boost. Focus on CRIT DMG over CRIT Rate.

Skill Priority: What to Level First 📈

Always prioritize her Core Skill first! It's the key to her kit.

1. Core Skill – Activates Furnace Fire, which is central to her damage and daze.

2. Basic Attack – You'll use this a lot after Furnace Fire is active.

3. Chain Attack – Significantly increases daze and damage, especially with Ben.

4. Special Attack – Still useful, but not as critical as the top three.

5. Dodge – Bottom priority; it doesn't impact her kit much.

Bangboo: Your Little Robo-Buddy 🤖

The right Bangboo can make Koleda's stun-lock even more effective.

• Rocketboo: With 2+ Fire agents, Bangboo Chain Attack inflicts 100% more Anomaly Buildup. Since Koleda and Ben are both Fire, this helps proc Burn more often.

• Safety: With 2+ Belobog Heavy Industries characters, Bangboo Chain Attack DMG increases by 20%. If the target is Burning or Shocked, add another 20%. With a mono-Fire team, this is a hefty 40% damage boost.

• Cryboo: A weaker Rocketboo, but still boosts Burn uptime by 60% more Anomaly Buildup.

Teams: The Belobog Blowout 💥

The classic team is Koleda + Ben + Soldier 11. This trio checks all the boxes for Fire synergy and Core Skill Additional Abilities. For Koleda, when there are at least 2 Fire or Belobog Industry agents, her EX Special explosion causes the target to take 35% more Chain Attack DMG while Stunned. This stacks twice and ends when the enemy recovers. That's a massive damage window for Soldier 11 to exploit.

Koleda is a team player. She's not meant to be the star DPS; she's the enabler, the breaker, the one who sets up the pins for someone else to knock down. And with Ben, she's even better. If you're looking for a Fire breaker, Koleda is a no-brainer. She's on the standard banner, so you might have to wait for a rate-up or get lucky. But if you're willing to spend, she's worth every penny.

So there you have it: a tiny president with a giant hammer, a bear sidekick, and a passion for setting things on fire. What's not to love?
