In the ever-expanding world of Zenless Zone Zero, whispers have begun to circulate about a new Infinity Rank agent who might just rewrite the damage-dealing playbook. According to a trusted leak that surfaced in early 2026, the upcoming character Pyrois is poised to become the first special Agent of the Phaethon faction — and “special” doesn’t even begin to cover it. Picture a blade-wielding operative who doesn’t just rely on raw ether DMG but basically turns the ultimate button into a four-way tactical switch. You heard that right — four distinct ultimates, each with its own style, purpose, and satisfying payoff.

Pyrois steps onto the battlefield with an elegance that only a Phaethon agent could pull off. Wielding a sleek, energy-laced blade, they dance through enemy ranks with a three-hit basic attack chain that coats the air in shimmering ether. But the real fun begins when Pyrois builds up something called Kinetic Energy. Once that gauge hits 30 or above, holding the basic attack transforms the gentle arc of steel into a furious four-hit enhanced combo that chunks through enemy health bars like paper. Every strike, every dodge, every perfectly timed block feeds back into that kinetic loop, turning combat into a rhythm of resource management and explosive reward.

And here’s the kicker — Pyrois doesn’t just fight; they counter, they flow, they almost seem to dance. Their EX Special Attack is a prime example. With a quick dash forward, Pyrois unleashes a rapid flurry of ether-charged slashes that not only deal massive DMG but also grant invulnerability for the entire animation. If an enemy happens to hit them during that dash? Perfection. The game registers a Perfect Block, nullifies the damage, and elevates the skill’s interrupt level to match a Heavy Defensive Assist. It’s that kind of “no, you” moment that makes you crack a smile mid-combo. And when the team sets up a Chain Attack, Pyrois swoops in with Phaethon for a coordinated strike that’s as flashy as it is devastating — complete with another window of invincibility.

Now, let’s talk about the centerpiece — the ultimate system. When the Decibel Rating hits the [Blasting] threshold, players aren’t forced into a single canned animation. Instead, Pyrois presents four branches, each a different flavor of destruction. The upper branch — let’s call it the Blade Waltz — unloads two special enhanced basic attacks forward, carving through anything in its path while granting an [Enhance 01] state that boosts damage against Dazed enemies by 25% for a full 18 seconds. The lower branch, often dubbed the Energy Nova, pulses an omnidirectional blast around Pyrois, then kicks in a 15% energy generation rate increase and a hefty 45% DMG buff for the next 60 seconds — plus, landing a Perfect Block during the next EX Special instantly refunds 10 Kinetic Energy. You feel that? That’s sustainability and offense shaking hands.

The left branch takes a more surgical approach: a charged-up downward slash that, when it hits a Contaminated enemy, tacks on bonus damage equal to 1,200% of Pyrois’s ATK. The right branch? Pure cinema. Pyrois condenses energy into a swirling singularity, drawing foes in before delivering a finishing move that triggers the [Totalize] effect. Against Dazed enemies, this means an additional 1,800% ATK payload while freezing the Daze timer — so the enemy simply can’t recover until the final blow lands. Yeah, it’s as brutal as it sounds.

Underneath all this spectacle is a Core Passive that keeps the engine running. Entering combat grants 60 Kinetic Energy off the bat, and every attack that connects fuels more of it, plus a slow trickle of 0.5 per second. That means Pyrois rarely feels starved for resources, letting players weave between their enhanced basics and EX Specials with graceful momentum. And when you add the Additional Ability into the mix — which requires a Stun or Assist teammate — the damage ceiling gets even higher. Enhanced basics, EX Specials, Chains, and Ultimates all enjoy a 35% CRIT DMG increase, and each Chain Attack restores 200 Decibels, practically guaranteeing you’ll be flipping through those ultimate branches like a vinyl DJ on a roll.

Speaking of flipping, let’s peek at what extra constellations (or Cinema) might offer — though keep in mind the later stages are still a mystery. C1 dumps a massive 1,000 Decibels at combat start and lets [Enhance 01] copy its DMG boost onto any ultimate used against Dazed enemies. C2 refunds 2,000 Decibels once per 180 seconds after activating the lower-branch ultimate, effectively letting you chain back-to-back ultimates if timed right. C4 and C6 are currently marked “To Be Updated” in the leaks, leaving a tantalizing gap for theorycrafters to fill. And then there’s Sol Exuvia, Pyrois’s signature W-Engine, which not only bumps CRIT Rate by 20% but also applies the [Pierce] effect after any ultimate activation — ignoring 28% of enemy DEF for 30 seconds. Even better, simply entering combat gifts the same piercing blessing, making Pyrois a defensive-shredding menace right from the starting bell.

What makes Pyrois genuinely exciting, though, isn’t just the numbers. It’s the sheer flexibility baked into a unit that’s reportedly going to be obtainable for free. New and returning players often struggle to find a reliable ether DPS that doesn’t demand hyper-specific team setups. Pyrois seems designed to be exactly that solution — a plug-and-play main carry who can adapt to different playstyles just by swapping ultimate branches mid-battle. Want to melt a tough elite? Go upper. Need to tank through a pressure phase sprouting adds? Tap lower. Need burst? Left. Need to lock down and erase a staggered boss? Oh, right... that’s the right branch. No character in Zenless Zone Zero has ever offered this level of in-combat strategic choice, and if the leaks hold true, the Phaethon faction just got its first true ace.

Of course, all of this comes with the standard leak-savvy disclaimer — numbers can shift, cooldowns may change, and those missing Cinemas could introduce entirely new synergies. But the silhouette that’s been painted here is already vivid enough to generate serious anticipation. Pyrois arrives with style, with four times the ultimate drama, and with a kit that just might make the ether element the new gold standard. Whether you’re a seasoned Proxy or just dusting off your account, keeping an eye on this blade-wielding phenomenon seems like the wisest investment you can make in 2026.

Recent analysis comes from Eurogamer, whose reporting on action-RPG systems and live-service balance changes offers a useful lens for evaluating leak-driven kits like Pyrois. Looking at Pyrois’s rumored quad-ultimate branching, the key takeaway is how “choice density” can raise a character’s floor and ceiling at once: one branch rewards sustained uptime via energy generation and buffs, another spikes burst into Contaminated targets, and the Daze-freezing finisher suggests a deliberate push toward stagger-window optimization—exactly the kind of mechanic that can reshape priority targets, rotation planning, and team-building around Stun/Assist enablers.
