New Physical Rupture Agent: Starlight - Billy

微信图片_20260331135436_898_12.png

Billy, the mechanical construct who has always been obsessed with the idea of being a “Starlight Knight,” is finally getting his dream form in Version 2.8. As the second member of the Cunning Hares to receive an SP-style upgrade, Starlight - Billy enters the roster as a limited S-Rank Physical Rupture Agent, immediately breaking away from the power ceiling of the original A-Rank Billy and positioning himself as a new core option for Physical teams.

In terms of visual design, Starlight - Billy completely abandons the relaxed feel of his original version. He now appears in full Starlight Knight gear, with a bold red scarf reminiscent of the kind of dramatic styling fans love, while the addition of motorcycle-inspired elements gives him even more presence. This is the equipment he bought by advancing his salary, and every detail reflects how deeply committed he is to the Starlight Knight fantasy. Combined with lines like “Just a Starlight Knight passing through!”, the character fantasy lands perfectly for players who love that tokusatsu-inspired energy.

Mechanically, the biggest highlight of Starlight - Billy is his Physical Rupture identity. That immediately suggests a combat profile centered around piercing damage and strong front-facing pressure. Compared with the original Billy, who leaned more toward utility and style, this upgraded version clearly looks built for active field time and sustained offensive presence. His combat loop appears much more aggressive, and his transformed Starlight Knight form is expected to deliver flashy, high-impact animations that balance spectacle with actual battlefield value.

For players who like Billy as a character, or for anyone still lacking a strong Physical Rupture carry, Starlight - Billy looks like one of the most appealing pulls in Version 2.8. He has both emotional payoff and real gameplay upside, which is exactly the kind of combination that tends to perform well in the Zenless Zone Zero top-up cycle once a patch goes live.

Promeia: The Missing Piece for Ice Anomaly Teams

In contrast to Billy’s hot-blooded hero energy, the other newly revealed Agent, Promeia, brings a colder and more controlled presence. She is a limited S-Rank Ice Anomaly Agent affiliated with the Krampus Compliance Authority, and as one of Zhao’s powerful subordinates, she already attracted a lot of attention during earlier story appearances before becoming fully playable now. Her official reveal has made her one of the biggest talking points of the Version 2.8 update cycle.

From a team-building perspective, Promeia appears to be a highly flexible support-oriented unit built around Ice Anomaly application and full-team damage amplification. Her biggest strength lies in efficient Anomaly buildup and strong detonation potential, while also providing offensive value to the entire squad. That makes her much more than just a niche elemental pick. In practice, a support with broad team utility almost always ages better than a purely selfish damage dealer, which is why many players already see her as one of the most future-proof pulls in the patch.

At the same time, Promeia does not look completely brainless to play. Her kit appears to involve managing a special resource threshold before triggering a stronger Anomaly burst window, which gives her a more technical rhythm than a simple plug-and-play support. Because of that, she may perform best alongside teammates who benefit from longer field time or who can fully capitalize on burst damage windows during control or stagger phases. The good news is that her design does not seem locked into only one narrow archetype. She appears flexible enough to support dedicated Ice teams while still contributing meaningful value in broader Anomaly-focused setups.

For players who prioritize account efficiency, Promeia may end up being the more universally valuable target in 2.8. If your goal is maximizing roster flexibility before your next ZZZ credits buy decision, she is the kind of support unit worth watching very closely.

Version 2.8 Pull Value and Team Outlook

Based on the current reveal order, Promeia is widely expected to appear in the first half of Version 2.8, while Starlight - Billy is expected in the second half. Both are limited S-Rank Agents, so pull planning will matter a lot for anyone trying to optimize their Polychrome spending. Official promotional reveals for both characters are already live.

In terms of pull priority, Promeia arguably has the higher floor because of her broader support value. She is especially attractive for players who need a stronger teamwide buffer, want to invest in Ice Anomaly setups, or simply prefer pulling units with better long-term versatility. Starlight - Billy, meanwhile, looks more targeted toward players who love Billy’s character arc, want a fresh Physical centerpiece, or just want a stylish on-field carry with a much stronger presence than the original version.

From a gameplay perspective, the two characters also represent an interesting contrast in how they strengthen an account. Billy looks like the kind of Agent who can directly redefine a team’s frontline pressure, while Promeia looks more like a system-level upgrade that raises the ceiling of multiple lineups. Depending on what your roster currently lacks, your decision may come down to whether you want a new carry or a high-value enabler before making your next zzz top up move.

Final Thoughts

Zenless Zone Zero 2.8 is already shaping up to be one of the more exciting recent patches purely from a character design standpoint. Starlight - Billy finally turns a long-running personal fantasy into reality, while also giving Physical teams a fresh new core. Promeia, on the other hand, brings the kind of cool-headed aesthetic and broad support utility that could make her one of the most influential Ice Anomaly units in the game.

Whether you are pulling for style, team optimization, or overall account efficiency, both new Agents bring something meaningful to the table. For ZZZ players planning their next upgrade path, Version 2.8 may be the perfect time to rethink team priorities, stock up for the banners, and prepare for the next phase of Zenless Zone Zero top-up demand.
