5 Best Characters in Chaos Zero Nightmare Guide & Why

With the global launch of Chaos Zero Nightmare approaching, knowing which characters to focus on can give you a huge advantage. Some heroes stand out due to their damage output, support capabilities, or utility in decks.

We’ve picked these five characters based on beta testing and balance updates. They excel in both roguelike stages and boss battles, offering a mix of raw damage, resource efficiency, and team synergy.

Focusing on these heroes early can make your early game smoother and give you more strategic options for building decks. This guide highlights the top 5 characters that can carry your team efficiently and explains why they are considered the best choices.


1. Mika – AP Support / Controller

Mika is a meta-defining support character. Her core strength lies in restoring Action Points (AP) for the entire team, letting your main DPS use high-cost skills more frequently. This AP regeneration significantly increases skill rotation efficiency and overall damage potential, making her a cornerstone for any team reliant on combo strategies.

2. Khalipe – Vanguard / Frontline DPS

Khalipe excels as both a tank and a damage dealer. Her “Vulture Launch” skill triggers automatically when playing higher-cost cards, dealing AoE damage, generating shields, and returning to hand. This allows her to continuously protect the team while contributing damage without consuming extra AP, making her one of the most well-rounded frontliners.

3. Mei Lin – Fire-element Single-Target DPS

Mei Lin is a top pick for boss battles. Her opening card applies Elemental Weakness to enemies, boosting all subsequent fire-element attacks by 25% and increasing Break damage. This makes her ideal for teams lacking elemental advantage, and her AP restoration after breaking enemies keeps her skill rotation highly efficient.

4. Hugo – Order-element Combo DPS

Hugo is a versatile sub-DPS who thrives on stacking follow-up attacks. He generates “Hunt Commence” stacks when allies play non-attack cards, which he can consume to perform extra attacks. Hugo’s efficiency allows him to deal significant damage without relying on AP, making him excellent for both early and late-game content.

5. Renoa – Void-element Single-Target Burst DPS

Renoa specializes in single-target damage, making her perfect for high-HP bosses. She generates “Bullet” cards that trigger extra attacks when using her other skills. The more bullets she has, the stronger her burst potential. Renoa’s ability to scale damage with card accumulation makes her a must-have for focused DPS strategies.


These five characters—Mika, Khalipe, Mei Lin, Hugo, and Renoa—are standout options in Chaos Zero Nightmare due to their utility, damage output, and team synergy. Prioritizing them when building your roster will give you a strong foundation for both roguelike progression and challenging endgame content. Experiment with their deck setups, find the best combinations, and dominate your runs from day one.
