Goddess of Victory: Nikke Delta: Ninja Thief Review
To review if this character is worthy of a time, you'd better understand both her strengths and weaknesses. Delta: Ninja Thief works as a supportive Defender who adjusts her actions depending on who’s on her team, especially when other Defenders are present. She shines in battles where enemies have multiple weak points, as her distributed damage boost helps teams handle complex boss fights more smoothly.
She comes with Burst Skill, which strengthens both her own defense and her team’s attack power, making her a dependable option for long battles that require balance between protection and offense. But, similar to many other characters, she has her own perks and downs, so here is how she shines and weakens:
Strengths
-
Performs best in Defender-based teams, where her skills adapt to enhance overall teamwork.
-
Excels at boosting distributed damage, giving her an edge in fights against bosses with several targetable parts.
-
Her Burst Skill improves allies’ attack power while increasing her own toughness, making her a balanced mix of tank and support.
-
As a Water-type Nikke, she can deal bonus damage to Fire-type enemies, adding valuable elemental flexibility.
Weaknesses
-
Her performance relies heavily on Defender synergies, so she may not perform as well in teams with different setups.
-
Using a Machine Gun means she needs proper gear or overloads to handle reload time and ammo more effectively.
Overall Rating: 8/10
So in general, Delta: Ninja Thief looks like a solid choice for anyone focusing on Defender teams or those drawn to her phantom thief theme. Her future standing in the meta will depend on her confirmed Burst Type, which could change her role significantly. She’s expected to do well in general PvE modes, but her PvP impact might stay modest until more detailed stats are available.

Skills Breakdown for Delta: Ninja Thief
Delta: Ninja Thief’s abilities focus on adaptive defense and team support. While full scaling numbers are not yet confirmed, you can still get a good idea of what to expect from her skill set with the following.
-
Adaptive Passive: Her passive ability changes behavior when she’s near other Defenders. This likely adjusts her attack style or activates special effects that help the team perform better together.
-
Ally Boost: This ability strengthens her team’s distributed damage attacks, making her especially useful in boss fights against enemies with multiple parts, such as Modernia or Grave Digger.
-
Burst Skill: Her Burst Skill raises the team’s attack power and increases her own durability, possibly through shields, healing, or damage reduction. It functions as part of the usual Burst chain (Burst I → II → III for Full Burst).
Delta: Ninja Thief Best Builds
For her setup as a Machine Gun Defender, you can focus on gear that boosts survivability, reload speed, and buff strength. Try testing different combinations in the Simulation Room or Union Shooting Range, where she will be available as a trial unit before full release. This lets you experiment with her build and find the best setup for your playstyle.
Recommended Equipment (Overload Gear)
To get the best out of Delta: Ninja Thief, focus on gear that balances defense, survivability, and machine gun performance. Here’s how to optimize her loadout:
|
Helmet |
Choose Max HP or Defense to help her absorb more damage during long battles |
|
Gloves |
Go for ATK or Elemental Damage to boost her Water-type bonuses |
|
Chest |
Defense or Max Ammo works best since a larger magazine helps maintain consistent damage output |
|
Boots |
Pick Max HP or Reload Speed to support her sustain during continuous firing |
Overload Priorities: Aim for Max Ammo Capacity, Reload Speed, and ATK%. Skip Charge Speed and Charge Damage since they don’t benefit machine gun users.
Harmonic Cube Recommendations
|
Resilience Cube |
Boosts HP for better tanking |
|
Bastion Cube |
Strengthens her defense to withstand heavy hits |
|
Adjutant Cube |
Useful if you want to enhance her team support role |
Best Delta: Ninja Thief Team Compositions
Delta: Ninja Thief performs best in teams built around Defenders. Her adaptive skill set benefits from having allies of the same class nearby, allowing her to adjust her abilities for better coordination and survivability.
There are two team setups we can recommend to you here as:
|
Bossing Team (PvE Setup) |
Burst I: Biscuit (Defender Support) Burst II: Crown (Team Buffs) Burst III: Delta: Ninja Thief (if confirmed Burst III; provides attack boosts) Additional Slots: Cinderella (for distributed damage) and Maiden (for tanking). Playstyle: Focuses on steady distributed damage and strong survival during multi-phase boss fights. |
|
Alternative Defender Stack |
Suggested Team: Cinderella (Burst I), Rouge (if Delta is Burst III), Delta: Ninja Thief, Crown, and Maiden. Playstyle: Prioritizes Defender proximity effects to activate Delta’s adaptive bonuses and team buffs. |
Note: Avoid placing her in burst-heavy teams like Scarlet or Alice setups unless testing later proves otherwise. She’s designed for gradual team scaling, not high-risk, high-reward damage bursts.

For Whales and Collectors: Yes. If you enjoy running Defender-heavy teams or like her Phantom Thief story, she’s a fun and cohesive addition. Her skill set feels interactive and should pair well with similar units.
-
For F2P and Low Spenders: It’s better to save your resources for the upcoming 3rd Anniversary event in late October or November 2025, which is likely to introduce stronger and more impactful Nikkes. Delta’s kit is somewhat niche, and she will eventually join the standard recruitment pool.

People Also Ask
How does Delta: Ninja Thief perform in Solo Raid and Tribe Tower?
Delta: Ninja Thief’s focus on distributed damage makes her a strong pick for Solo Raid bosses with multiple parts, like Nihilister, where she can amplify team DPS. In Tribe Tower, her Water element excels against Fire floors, and her Defender synergy boosts tanking reliability. Compared to Defenders like Noah or Biscuit, she’s less about raw damage mitigation and more about enabling consistent team output, but her performance shines in prolonged fights.
What are the best stages to farm event currency with Delta: Ninja?
Focus on the highest-difficulty event stages where Delta: Ninja Thief’s +60% currency bonus maximizes drops. Pair her with other event bonus units like Phantom or Quency for efficiency. Prioritize stages with Fire-coded enemies to benefit from her Water element advantage, ensuring faster clears and better rewards.
Can Delta: Ninja Thief be used effectively in Arena (PvP) with free-to-play builds?
In Arena, Delta: Ninja Thief’s Defender role and adaptive buffs are less impactful due to the burst-heavy meta favoring units like Scarlet or Red Hood. For F2P players, her viability depends on pairing with budget Defenders like Anis: Sparkling Summer to trigger her synergy. Focus on overloading Reload Speed and Defense to sustain her Machine Gun uptime. She’s not a top-tier PvP pick but can work in niche stall teams against slower opponents.
Conclusion
And that is all for our Goddess of Victory: Nikke Delta: Ninja Thief review and build guide.
