Peacekeeper - Specialized is an A-rank W-Engine in Zenless Zone Zero, and it occupies a unique niche among Defense-type engines. As the signature weapon of Seth, it is designed to help defensive agents apply Anomalies more frequently while also providing a boost to Energy Regen. But why would a Defense W-Engine care about Anomaly application? The answer lies in the way certain agents can turn defensive play into consistent elemental pressure. In 2026, with the roster expanded and team compositions more varied than ever, Peacekeeper - Specialized remains a noteworthy option for players who want their defensive characters to contribute more than just survivability.

Stats and Effects

Peacekeeper - Specialized offers a blend of defensive stats and offensive utility. Its primary role is to enhance the user's ability to inflict Anomalies, which makes it a strong choice for agents who rely on building up attributes like Fire or Electric to trigger status effects. The W-Engine also provides an Energy Regen boost, allowing its user to use EX Special Attacks and Ultimate abilities more often. This combination is particularly valuable in prolonged fights where consistent Anomaly buildup can lead to frequent disorders or elemental damage over time.

Signature Agent	Seth
Key Effects	Anomaly application boost, Energy Regen boost
Best For	Defensive agents who want to trigger Anomalies more often

It is important to note that while the W-Engine is classified as a Defense engine, its passive effect pushes the user toward a more active role. Players who enjoy using defensive characters as enablers rather than pure tanks will find this engine particularly appealing. Is it a must-pull for every account? Not necessarily, but for those who main Seth or want to explore Anomaly-focused Defense teams, it is a highly valuable tool.

Best Characters

The recommended agents for Peacekeeper - Specialized are arranged from most to least recommended. The list is short but impactful.

1. Seth – The Signature User

Seth is the primary recommended Agent for this W-Engine. As the signature weapon, Peacekeeper - Specialized is tailored to his kit, and it amplifies his ability to apply Electric Anomaly while maintaining his defensive utility. Seth players who want to maximize his supportive capabilities will find that this W-Engine synergizes perfectly with his playstyle. In 2026, Seth remains a solid pick in Electric-focused teams, and this engine helps him contribute meaningful Shock buildup alongside his shield and buffs.

2. Ben – The Fire Anomaly Enabler

Ben is the second-best user of Peacekeeper - Specialized. Putting Ben in a Fire Team can enable him to inflict Burn more frequently than normal, which comes in handy in situations that require sustained Fire damage, such as fighting the Rampant Brute boss. He also benefits greatly from the Energy Regen boost, allowing him to use his EX Special Attack more often to protect his teammates and apply more Fire Anomaly. For players who enjoy Ben's defensive yet explosive playstyle, this W-Engine is a fantastic fit.

Why does Ben work so well with this engine? His Fire attribute and defensive kit naturally align with the W-Engine's Anomaly-focused passive. When paired with another Fire agent, Ben can become an unexpected source of Burn application, turning his defensive presence into a consistent offensive threat.

How to Get Peacekeeper - Specialized

Players who are targeting this W-Engine should keep an eye on their standard pulls and take advantage of any rate-up events that may feature it. However, because it is a standard A-rank engine, it is not guaranteed to appear quickly, so patience is key.
