Chaos Zero Nightmare Tier List [November 2025]

CZN (Chaos Zero Nightmare) is a deck-building roguelite gacha game with plenty of characters for you to get and master. However, not all characters are equally difficult, nor as balanced, making your choices when summoning/upgrading that much more important. To help you learn who the best characters are, all the best team comps, and more, here is our ultimate Chaos Zero Nightmare tier list!

S Tier: The best overall characters in Chaos Zero Nightmare with the potential to be broken, no matter what other characters you are using.

A TIer: Very good characters and those that don’t need a lot of support and will perform really well with proper play.

B Tier: Characters that can be better than S/A-tier ones, but require some other characters on the team, specific epiphanies, upgrades, or very precise play.

In the tier list above is the ranking of all characters in Chaos Zero Nightmare based on their overall strength and difficulty. Unlike most gacha games, in CZN, all characters are viable, and the difference in power between tiers is fairly low. Team, build, epiphanies, and everything else will have a huge influence on how a character performs. So, take this tier list as more of a priority guide on who to get/upgrade first. Scroll down for the rankings and character summaries.

S Tier – Best Characters in Chaos Zero Nightmare

Character	Details & Ranking Summary	Best Team
Khalipe	5-Star Instinct Vanguard Tank DPS AoE High-Cost Khalipe is a tank/bruiser with amazing AoE damage and high defense. Her Vulture Ejection procs when you use cards with ≥2 cost, and it deals very high AoE DMG every turn. However, spamming high-cost cards too much might put you at a disadvantage, forcing you to use Mika as support. Also, Khalipe is one of the most reliable and self-sufficient characters in CZN.	Haru Mika
Kayron	5-Star Void Psionic DPS AoE Single-target High-Cost Exhaust Kayron is one of the best DPS characters in CZN, with his kit revolving around using cards with the Exhaust property to buff the damage of his DPS cards. Since there are so many characters who generate cards and can exhaust them, such as Orlea, Renoa, Luke, etc., there are very few teams that he won’t fit into.	Rei Mika
Hugo	5-Star Order Hunter DPS Single-target Medium-Cost Extra Attack Haste Hugo is a single-target DPS with insane damage potential due to his ability to dish out a barrage of Extra Attacks every turn with his Hunt Commence passives. He is especially good when paired with Nia, as her Soul Rip can buff ally Extra Attack DMG. Hugo is one of the best main DPSs in CZN, and he doesn’t need much support at all to perform extremely well.	Tressa Mika
Mei Lin	5-Star Passion Striker DPS Single-target Medium-Cost Passion Weakness Mei Lin is a single-target DPS who can burst enemies incredibly quickly, and she doesn’t need any help to do it because of her self-sufficient deck. She can be used as the main DPS on any team, though proccing Passion Weakness with Selena will make her even more busted.	Selena Mika
Mika	4-Star Justice Controller Support AoE Low-Cost Healer AP Regen Mika is by far the best and most well-rounded support character in Chaos Zero Nightmare. She provides an insane amount of heals, relatively decent AoE, and free Action Points. Mika is just really good and one of the few supports that you can just put into any squad, and she’ll make the whole team unkillable.	Anyone

A Tier – Very Strong & Easy / Versatile Characters

Character	Details & Ranking Summary	Best Team
Orlea	5-Star Instinct Controller Support Single-Target Medium-Cost Healer Buffer Orlea is one of the best support/healer/buffer characters in Chaos Zero Nightmare, with cards that get buffed as they stay in her hand and very simple gameplay. Plus, because of her insane utility that gets stronger with each turn you spend retaining her cards, she is one of the few characters that will help you beat very difficult stages that most other characters won’t.	Beryl Owen
Haru	5-Star Justice Striker DPS Single-target AoE High-Cost Haru is a single-target/AoE DPS with scaling damage on her best DPS card (Anchor Shot) and a relatively simple and easy-to-use kit. She is especially strong as a main DPS, and some of her cards allow you to search and buff Anchor Shot, accelerating its DPS ramp-up. Characters like Orlea, Cassius, and Mika can provide her with regen and utility and make her of the best single-target DPSs in CZN.	Khalipe Mika
Magna	5-Star Justice Vanguard Tank AoE High-Cost Counter Magna is a tank/support who provides your team with all the shields and Counter stacks they’ll ever need. She works especially well with other characters that can stack shields, such as Amir, Maribell, etc. She can be placed onto any squad, and she will perform very well as a defensive character. For offense, though, she isn’t that good at all.	Khalipe Mika
Veronica	5-Star Passion Ranger Support DPS Low-Cost Single-Target Veronica is a sub-DPS character who relies on generating her unique Ballista Cards that proc at the end of the turn. Because Veronica’s DPS cards proc at the end of the turn, she is very AP-efficient and versatile. You can slot her into any team, and she will perform well as a sub-DPS.	Mika Nia
Maribell	4-Star Passion Vanguard Tank Single-Target Medium-Cost Maribell is a single-target DPS/bruiser who performs similarly to Magna but with a higher focus on dealing damage. Her kit is fairly self-sufficient, and she benefits from shield-stacking allies, the same as Magna. If you need a tank that requires minimal game knowledge, she is one of the best ones.	Magna Mika
Nia	4-Star Instinct Controller Support Single-Target Low-Cost Healer Buffer Nia is a support/healer/buffer who can buff your allies’ Extra Attack DMG and have them join her Joint Attacks. She has plenty of utility, but her main use is as a support for Hugo / Selena and any other character who relies on Extra Attacks for damage.	Hugo Tressa
Selena	4-Star Passion Ranger DPS Support AoE Single-Target Low-Cost Buffer Passion Weakness Selena is a single-target/AoE DPS and support for Passion Weakness / Extra Attack allies. She also provides very good shields and applies Mark, dealing Extra Attack DMG when using Attack cards. Her whole kit is very simple, and she is one of the best DPS supports in CZN, especially for Hugo, Nia, and Mei Lin.	Mei Lin Mika
Lucas	4-Star Passion Hunter DPS AoE Medium-Cost Bullet Lucas is an AoE DPS and fairly similar to Luke, who is another Bullet-stacking character. His AoE DPS is one of the best in the game, and he has a fairly reliable kit, making him a solid addition to any squad that is missing AoE damage. He is generally one of the best 4-star DPSs in Chaos Zero Nightmare.	Luke Mika
Tressa	4-Star Void Psionic DPS Single-target Medium-Cost DoT Tressa is a single-target DPS who can apply various DoT effects to enemies and spam low-cost cards every round. She also provides heals and other utility, making her a solid sub DPS who can also fill the support role a bit as well.	Hugo Mika
Rei	4-Star Void Controller Support Single-Target Low-Cost Healer Buffer Rei is a support/buffer and a jack-of-all-trades type of character. She provides heals, DMG buffs, and DPS. She is especially strong with characters that spam 1-Cost / Basic Attack cards such as Renoa, as her Resonating Darkness and Strike of Darkness can buff the 1-Cost/Basic Attack damage immensely. However, on teams that rely on different types of cards for DPS, she will be very underwhelming.	Mei Lin Selena
Owen	4-Star Passion Striker DPS AoE Single-target Medium-Cost Owen is an AoE/single-target DPS who is very versatile and provides shields for the team as well. He is fairly easy to use because of his straightforward kit, and his damage is respectable, though not as good as Hugo’s, Kayron’s, or some other meta DPS. Also, he is one of the characters you’ll get for free early on.	Rei Nia
Beryl	4-Star Justice Ranger DPS Single-target Medium-Cost Retain Beryl is a single-target DPS whose main damaging cards (Opening Found and Charged Shot) rely on you retaining them in your hand for at least 1 turn to charge up their damage. Her one-turn damage is extremely high, but it requires precise play and patience to pull off well. Also, since she doesn’t require her cards to be played to proc the effects, she is very good as a sub DPS.	Orlea Mika

B Tier – Strong But Difficult / Situational Characters

Character	Details & Ranking Summary	Best Team
Renoa	5-Star Void Hunter DPS Low-Cost Single-Target Difficult Renoa is one of the most broken single-target DPSs in CZN, with her whole kit revolving around her Dirge Bullets. She is completely self-sufficient and very rewarding if you know how to utilize her kit and just an extremely strong single-target DPS. Also, she works really well with Nia / Rei and any other character that can provide buffs for her unique kit.	Cassius Nia
Rin	5-Star Void Striker DPS Single-target Medium-Cost Difficult Rin is a single-target DPS that requires precise gameplay but can be extremely rewarding if you know how to chain her cards well. Her biggest drawback is that she doesn’t want to use other characters’ cards much and instead focuses on only hers. If you know what you’re doing, she will be a very good DPS, but if you don’t, she will feel almost useless.	Rei Beryl
Luke	5-Star Order Hunter DPS Single-target Low-Cost Bullet Needs Upgrades Luke is a single-target DPS with the ability to generate a bunch of Bullet Cards (with Rapid Fire) if he has enough Crit Chance and can then use those Bullet Cards to deal very high damage each turn with virtually no cost. He is one of the best endgame DPSs in CZN but doesn’t work that well early on because he needs a lot of Crit Chance to take advantage of Rapid Fire’s effect.	Lucas Mika
Cassius	4-Star Instinct Controller Support Single-Target Medium-Cost Difficult Cassius is one of the most RNG and complex support characters in Chaos Zero Nightmare, but if you know how to utilize your deck well, he can provide immense value for your team. He relies on discarding/drawing cards and hitting precise sequences to finish quests from Pop Eyed Popper to get free draws. He is really good, but both his skill floor and skill ceiling are really high.	Kayron Mika
Amir	4-Star Order Vanguard Tank Low-Cost Amir is a tank and one of the weakest characters in CZN in terms of DPS, but she makes up for it with her excellent defensive potential. She has shields, damage reduction, healing buffs, and more. Similarly to Mika, she is especially strong for the early game, as she makes tanking all the enemy damage trivial.	Maribell Mika
