Chaos Zero Nightmare T0 Tier Characters 

These are the Chaos Zero Nightmare characters that feel strong no matter the stage—you pick them, and the game just gets easier.

Mika

A healer who also gives AP (Action Points) is rare in a card-based game. That's why Mika is core meta — she speeds up your entire team's rotation, lets your DPS play expensive cards earlier, and keeps everyone healthy. If you're rerolling, Mika is always a safe investment.

Mei Lin

When you need one enemy deleted fast, Mei Lin is the most reliable pick. She applies weakness consistently, ramps damage with her mechanics, and keeps strong performance even without a perfect setup. 

In every Chaos Zero Nightmare tier list, she lands at the top because she simply never falls off. It is best for players who struggle with bosses, need a high Break value, and want a consistent, easy-to-trigger burst.

Veronica 

Veronica's Ballista follow-ups are basically "free damage every turn". Once she gets going, enemy HP evaporates. She also draws cards for the team, which helps smooth out awkward hands.

It is the best choice for players who want passive damage, want a sub-DPS that scales without effort and run combo teams.

Hugo 

If you enjoy high-tempo teams that punish enemies multiple times each turn, Hugo fits perfectly. He shines especially in harder content where fights last long enough to stack his effects properly.

Chaos Zero Nightmare T0.5 Tier Characters

T0.5 units are the second best in this Chaos Zero Nightmare tier list. They deliver reliable power and shine with the right team support.

Tressa 

Tressa excels in fights where enemies have high damage reduction. Her DoTs stack fast and shred bosses over time. Great for Chaos stages with healing or defensive buffs.

Haru

Haru is incredibly simple to use and hits hard. Her ability to pick specific cards from the discard pile gives her guaranteed burst windows. With an AP generator like Mika, she becomes one of the most explosive DPS in the game.

Khalipe

Khalipe is a tank, but she doesn't play like one. Her hybrid offence/ defence mechanics let her deal good AoE damage while helping stabilise your front line. Long fights make her shine.

Cassius

If you hate bricked hands, Cassius fixes them. He heals, redraws, and keeps your deck flowing — making him valuable in almost any team comp.

Chaos Zero Nightmare T1 Tier Characters

These characters perform well in most situations, especially if you enjoy flexible builds and steady progression. Continue reading to learn more about the T1 characters in this Chaos Zero Nightmare tier list: 

Magna

If you like slow, defensive, comfortable gameplay, Magna performs very reliably. It is safe and stable, hence one of the best Chaos Zero Nightmare characters for beginners.

Yuki

If you farm wave-based content or love clearing mobs with style, Yuki is your girl. Cards that activate when drawn + easy AoE spam = smooth Chaos Zero Nightmare gameplay.

Rin

When Rin gets the cards she wants, she destroys enemies. But you need the right setup, and without it, her pace slows down.

Kayron

Kayron becomes stronger over time, making him ideal for long fights. Early rotations feel clunky, but once his Exhaust mechanics ramp, he becomes deadly.

Selena

Selena is great for mixed teams. She chips away at multiple enemies and benefits greatly from multi-hit units.

Chaos Zero Nightmare T2 Tier Characters

This group includes Renoa, Luke, Maribell, Nia, Beryl, Lucas, Owen, and Amir. Most of them are niche picks — strong only when paired with specific synergies. Here are some quick notes to help you make the right choices:

Alt Text: Owen: A T2 tier character in Chaos Zero Nightmare tier list 

●Owen is beginner-friendly but outgrows quickly.

●Renoa has insane burst but horrible hand-clogging issues.

●Maribell is good in counter teams, but can't carry.

●Nia supports card manipulation well.

●Amir struggles due to low defensive base stats.

They can work, especially early, but are not ideal long-term investments.

How to Actually Use This Chaos Zero Nightmare Tier List?

Here's the part most Chaos Zero Nightmare guides don't tell you: tier lists only help when you combine them with smart team building. Here's the simplest formula that almost always works:

●1 Main DPS (Mei Lin, Haru, Hugo, Veronica)

●+ 1 AP/Healer (Mika or Cassius)

●+ 1 Utility Support / Tank (Khalipe, Selena, Magna)
