A Tier List classifies characters based on their general strength, versatility, ease of use, and performance across most game content. While some characters shine in niche roles or specific builds, Tier Lists focus on characters that perform consistently well.
Here's a general breakdown of what each tier means:
S Tier – Meta-defining characters; extremely powerful in most situations.
A Tier – Strong, flexible picks that work well in many teams.
B Tier – Supportive or situational characters that value combo plays.
C Tier – Weak by comparison; often require very specific builds or are outclassed.
Tip: Tier Lists are guides, not strict rules. Creative builds can make nearly any character work.
Below is a consolidated and detailed Tier List based on multiple community and strategy site rankings (updated through 2026):
| Tier | Representative Characters | Notes / Player Tips |
|---|---|---|
| S | Khalipe, Hugo, Mika, Chizuru | Core meta units; invest in these first. |
| A | Rin, Veronica, Haru, Orlea, Kayron, Magna, Nia, Maribell, Yuki | Strong and flexible; pair with complementary S-tier units. |
| B | Mei Lin, Cassius, Selena, Renoa, Luke | Require specific builds; great for synergy-focused players. |
| C | Tressa, Beryl, Rei, Owen, Amir | Early-game use only; pick only if you love the character. |
Note: Other sources may vary slightly — especially later meta tier lists in 2026. Characters like Nine, Narja, Sereniel, Rita, Diana, and Heidemarie appear as S/S+ in newer rankings, reflecting ongoing balance changes.

Let's walk through each tier with explanations.
These characters are top priority for pulls and upgrades. They're strong standalone units and synergize well with many teams.
Khalipe
Role: Vanguard (Tank + AoE)
Strengths: Excellent survivability, strong area damage, easy combo setup
Consistent performance in both PvE and roguelike runs.
Hugo
Role: DPS (Order / Ranger)
Strengths: High follow-up attack potential and serious damage output
Works especially well as a secondary damage dealer.
Mika
Role: Controller / Healer
Strengths: Best healing and AP generation in the early/mid game
Nearly every team benefits from her sustain and support combos.
Chizuru
Role: High burst DPS
Strengths: Explosive damage once developed
Powerful in chaos runs with optimized card builds.
Key Takeaway: S-tier units are generally safe investments, contributing value even without perfect builds.
These characters are very capable when paired with complementary units.
| Character | Role | Notes |
|---|---|---|
| Rin | Striker | Great for single-target damage |
| Veronica | Ranger | Summon mechanics add consistent extra damage |
| Haru | Jack-of-all | Reliable, but doesn't scale as hard late game |
| Orlea | Support | Shields & utility |
| Kayron | DPS | Balanced hybrid damage |
| Magna | Vanguard | Counterattack bonus + shields |
| Nia | Support | Boosts extra attacks |
| Maribell | Vanguard | Solid sustain & counter combo |
| Yuki | Striker | AoE damage specialist |
Why A Tier?
These characters have excellent roles in many comps but might lack the extreme versatility or raw power of S tier.
These characters can perform well, but they often require specific combos or setups to fully excel.
Mei Lin – Good single-target DPS with build timing needs
Cassius – Great card control, but harder to optimize
Selena – Trigger-focused damage playstyle
Renoa – Sub-DPS reliant on strong cards
Luke – RNG-dependent crit mechanics
When to use:
If you enjoy deep card synergy playstyles, these B-tier fighters can outperform expectation, but they're less beginner-friendly.
These characters are useful in early game but tend to fall off or have limited application:
Tressa – Strong early, weaker late
Beryl – Poor retention synergy
Rei / Owen / Amir – Lackluster scaling
Tip: Only invest if you love a character's playstyle, or if your roster lacks better options.
Chaos Zero Nightmare encourages three-character teams. Understanding team roles helps you maximize synergy:
| Team Role | Priority |
|---|---|
| Tank / Vanguard | keep enemies controlled |
| DPS (Single or AoE) | main damage engines |
| Support / Healer | sustain & assist |
A classic meta team could be:
Mika + Nia + Hugo — Support + Card draw + Main DPS
Khalipe + Maribell + Rin — Tank + Shielding + High Damage
Player Tip: S and A tier units fit these structures best, but B-tier can surprise with the right combos.
Reroll for S / High A Characters
Early rerolls to secure S tier pulls can accelerate your progression. If you're struggling to pull these powerful champions, Z2U offers cheap Chaos Zero Nightmare accounts. This is perfect for players who want immediate access to top-tier teams.
Focus Your Resources
Don't spread upgrade materials evenly — prioritize S and strong A characters first.
Experiment with Synergy
Some B tier units can outperform higher tiers if your comp triggers powerful epiphanies or card chains.
Keep Updated
As of April 2026, seasonal updates have added new characters like Nine, Sereniel, Rita, Diana that shake up rankings in some lists — meta evolves fast.
Chaos Zero Nightmare's tier lists aren't absolute rules — they're guidelines based on current meta trends and community data. Top tiers like Khalipe, Hugo, Mika, and Chizuru consistently excel in many team compositions, but creative players can make nearly any character work with the right cards and strategy.
