Chaos Zero Nightmare Tier List 2026: Best Units Ranked
Welcome to the most comprehensive Chaos Zero Nightmare (CZN) tier list for 2026. Whether you are a new operator entering the digital hellscape or a veteran looking to optimize your squad, knowing which units dominate the current meta is essential. In CZN, team synergy is king, but individual unit performance can carry you through the most brutal Nightmare Raids and Tower climbs.
The best units in Chaos Zero Nightmare 2026 are Zerath (The Void), Lilith, and Omega Zero. These S-tier characters offer unmatched damage per second (DPS) and utility, making them essential picks for any high-level composition. However, A-tier units like Valkyrie and Dante are also powerful alternatives if you lack the rare summons.
This guide ranks every playable character from S to C Tier based on their performance in the current endgame content, including Void Raids and Ranked PVP. We’ve analyzed stats, skill multipliers, and synergy potential to bring you the definitive ranking.
Ranking Factors: How We Grade CZN Units?
To ensure this tier list is accurate for March 2026, we evaluated each character based on the following criteria:
- Damage Output (DPS): How effectively a unit clears waves and bosses.
- Utility & Crowd Control (CC): Abilities that stun, freeze, or buff allies.
- Survivability: HP pools, defense stats, and evade capabilities.
- Ease of Use: How easily a character fits into standard team comps (F2P vs. Whale investment).
Complete Tier List (March 2026)
2026 CZN S-Tier List (Meta Defining)
These units are the absolute best in Chaos Zero Nightmare. If you pull them, invest your resources immediately. They define the current meta and trivialize difficult content.
| Unit Name | Role | Element | Key Stat | Why S-Tier? |
|---|---|---|---|---|
| Zerath (The Void) | DPS | Dark | Attack | Infinite scaling on skill casts. |
| Lilith | Support | Chaos | Speed | Team-wide revive and ATK buff. |
| Omega Zero | Hybrid | Void | Crit Rate | Ignores 50% enemy defense. |
| Nightmare Reaper | Assassin | Shadow | Crit Dmg | Stealth + One-shot execute. |
| Archangel Michael | Tank | Light | Defense | Invincibility shield for team. |
2026 CZN A-Tier List (Excellent Picks)
A-Tier units are powerful and reliable. They are often just one balance patch or specific gear set away from S-Tier. They excel in almost all game modes.
| Unit Name | Role | Element | Key Stat | Why A-Tier? |
|---|---|---|---|---|
| Valkyrie | Warrior | Fire | HP | High burst damage on entry. |
| Dante | Rogue | Wind | Speed | Consistent bleed stacks. |
| Shadow Fiend | Mage | Dark | Skill Haste | Strong AoE nuke potential. |
| Lady Justice | Support | Light | Healing | Consistent cleanse and heal. |
| Cyber Knight | Tank | Metal | Defense | Taunts and reflects damage. |
2026 CZN B-Tier List (Solid Performers)
These units are solid middle-ground choices. They are great for filling specific gaps in your roster but usually require higher investment (dupes/gear) to perform at endgame levels.
| Unit Name | Role | Element | Key Stat | Why B-Tier? |
|---|---|---|---|---|
| Iron Guard | Tank | Earth | Defense | Very tanky but zero utility. |
| Flame Mage | DPS | Fire | Attack | Good damage, long cooldowns. |
| Wind Walker | Rogue | Wind | Evasion | High dodge, low consistency. |
| Sniper X | Ranger | Metal | Crit Rate | Single target only. |
| Battle Medic | Support | Nature | Healing | Healing scales poorly. |
2026 CZN C-Tier List (Niche/Weak)
C-Tier units are generally outclassed by others in the same role. Avoid investing heavily in them unless you have no other options or love the character design.
| Unit Name | Role | Element | Key Stat | Why C-Tier? |
|---|---|---|---|---|
| Rookie | Warrior | Neutral | Attack | Starter unit, low stats. |
| Militia | Ranger | Earth | Speed | Outdamaged by everyone. |
| Scout | Rogue | Tech | Crit Dmg | Dies too quickly. |
| Turret | Specialist | Metal | Skill Haste | Immobile, easily destroyed. |
| Basic Caster | Mage | Water | Attack | Cooldowns are too long. |
Detailed Unit Analysis
Below is a detailed breakdown of every unit featured in our Chaos Zero Nightmare tier list. We cover their strengths, weaknesses, and optimal usage to help you maximize your team’s potential.
Zerath (The Void)
Zerath is currently the undisputed king of the CZN meta. His unique passive, “Void Consumption,” increases his attack power every time he uses an ability, allowing him to scale infinitely during long boss fights. He fits into almost any team composition and trivializes content with his massive cleave damage. If you want to clear the Void Raids, Zerath is a must-have unit.
Lilith
While she deals moderate damage, Lilith earns her S-Tier status through her unparalleled support kit. She is the only unit in the game currently capable of reviving fallen allies with 50% HP, which is a game-changer for survival in high-level Nightmare Dungeons. Additionally, her ATK buff boosts the team’s damage output significantly, making her a staple in speed-run comps.
Omega Zero
As the protagonist of the narrative, Omega Zero is a powerhouse accessible to dedicated players. He acts as a Hybrid unit, capable of tanking hits with his “Code: Defense” mode and dishing out millions of crit damage with “Code: Annihilation.” His ability to ignore 50% of enemy defense makes him particularly effective against high-armor bosses that give other DPS units trouble.
Nightmare Reaper
If you enjoy high-risk, high-reward gameplay, Nightmare Reaper is your go-to assassin. She enters a stealth state upon using her ultimate, making her untargetable while she delivers a devastating execution blow to the enemy with the lowest HP. She excels in PVP environments where picking off weak targets is crucial, though she can be fragile in prolonged PVE fights.
Archangel Michael
The ultimate defensive wall, Archangel Michael, changes the dynamics of any battle. His signature move, “Divine Protection,” grants the entire team a 3-second invincibility shield, completely nullifying boss ultimate attacks. While his damage is negligible, his utility in timing defensive cooldowns makes him essential for progressing through the hardest stages of the Tower of Chaos.
Valkyrie
Valkyrie is a Fire-element warrior who shines in burst compositions. Her “Wings of Fury” skill deals massive damage at the start of the battle, allowing you to delete weaker enemies instantly. However, her damage falls off slightly in longer fights compared to Zerath. She is an excellent investment for players focusing on the Arena where quick fights are common.
Dante
Dante is the master of Damage Over Time (DoT). His Wind-element attacks apply stacks of “Bleed” and “Rupture,” dealing percentage-based health damage to enemies. This makes him surprisingly effective against high-HP bosses. He requires a bit of setup time to get his stacks rolling, so he needs a tank to protect him during the opening seconds of a fight.
Shadow Fiend
A classic dark mage archetype, Shadow Fiend excels at clearing waves of enemies. His “Gravity Well” ability pulls enemies together and stuns them, setting them up for devastating AoE combos from your DPS units. While his single-target damage is average, his crowd-control capabilities make him a favorite for farming resource stages efficiently.
Lady Justice
Lady Justice serves as a reliable, straightforward healer and cleanser. Her abilities focus on removing debuffs—crucial in CZN where status effects like “Curse” and “Silence” are rampant. While she lacks the revive mechanic of Lilith, she provides more consistent healing output and is easier to build for early-game players due to lower energy cost requirements.
Cyber Knight
This Metal-tank is all about counter-play. Cyber Knight taunts enemies and reflects a portion of incoming damage back to the attacker. He thrives in specific matchups where enemies attack rapidly, effectively killing themselves against his shield. However, against heavy-hitting single-strike bosses, he can fall behind the raw mitigation of Archangel Michael.
Iron Guard
Iron Guard is a reliable, no-nonsense tank for your early-game progression. He has high HP and Defense stats and does his job well: standing in the front line and taking hits. Unfortunately, he brings zero utility (no shields, no taunts, no buffs), which limits his viability in the late game where mechanics matter more than raw stats.
Flame Mage
A staple for many starting accounts, Flame Mage offers decent AoE fire damage. He is great for clearing the initial story chapters. However, his skills have long cooldown animations, leaving him vulnerable for seconds at a time. He is a solid placeholder until you summon a higher-tier DPS like Zerath or Shadow Fiend.
Wind Walker
Wind Walker is an evasion tank rogue who relies on dodging attacks rather than mitigating them. When she works, she is amazing, dodging fatal blows and countering. However, RNG can be her downfall; if she fails a dodge check, she gets one-shot. This inconsistency keeps her out of the higher tiers for serious progression.
Sniper X
Sniper X is a single-target specialist. He deals incredible damage to one enemy but provides zero AoE value. In a game where you often face waves of 5-10 enemies, this is a significant drawback. He is usable in Boss Rush modes but struggles in general adventure content.
Battle Medic
Battle Medic is a water-element healer often found in the friend summon pool. While he provides decent sustain, his healing scales off his own HP, which is naturally low for a support unit. Without heavy investment in HP stat gear, he tends to fall behind the curve compared to Lady Justice or Lilith.
Rookie
The default starting unit. Rookie has balanced stats but no outstanding features. He is perfectly capable of clearing the first few zones, but you should replace him the moment you summon a 3-star or higher unit from the gacha. Keep him around for “Earth-only” restrictions if you lack better Earth options.
Militia
Militia is a basic ranged unit. While she attacks from a safe distance, her damage output is very low, and her utility is non-existent. She is essentially fodder for upgrading other units and should not be used in your main party past the tutorial phase.
Scout
Scout attempts to be a speed-based disruptor but fails to leave a mark. His stats are too low to survive sustained combat, and his utility doesn’t offer enough to justify the roster spot. He is often skipped over for better options even in the early game.
Turret
A stationary summonable unit. The Turret can distract enemies and deal chip damage, but its immobility is a massive hindrance in CZN’s mobile combat. Once enemies move out of its range, or if the boss uses an AoE attack, the Turret is instantly destroyed.
Basic Caster
As the name implies, this is the fundamental magic unit. She has the longest attack range in the game, but her projectiles are slow, and her fire rate is sluggish. She serves as a temporary solution for players lacking a proper mage but should be upgraded quickly.
Frequently Asked Questions (FAQ)
Who is the best starter character in Chaos Zero Nightmare?
The best starter character is Omega Zero if you reroll, as he carries you through mid-game content efficiently. If you get Valkyrie or Dante from your initial pulls, they are also excellent starting choices that will carry you through the early chapters.
Is Chaos Zero Nightmare F2P friendly?
Yes, CZN is fairly F2P friendly. The game provides enough free currency to hit “pity” on a banner roughly once a month. Additionally, A-Tier units like Dante and Cyber Knight are viable for clearing all endgame content without requiring the rare S-Tier units.
How do I reroll in CZN?
To reroll, you must clear the tutorial and Chapter 1-4 to unlock the mail system. Claim your pre-registration rewards and summon on the banner. If you don’t get a top-tier unit, go to settings, select “Reset Account,” and bind a new guest ID to start over.
What is the best team composition in 2026?
The most reliable team composition for general content is 1 Tank, 1 Healer, and 3 DPS. For example: Archangel Michael (Tank), Lilith (Support), Zerath (DPS), Dante (DPS), and Shadow Fiend (DPS/CC). This covers survivability while maximizing damage output.

Conclusion

The meta in CZN is constantly shifting with new balance patches and character releases, but the units listed in S-Tier and A-Tier are currently your safest bets for dominating the battlefield.
