Building the Ultimate Team: A Guide to Zenless Zone Zero Factions in 2025

In the neon-drenched streets of New Eridu, a Proxy's success isn't just about the strength of individual Agents; it's about the bonds they forge and the banners they fight under. HoYoverse has masterfully woven a world where team-building is an art form, encouraging players to experiment wildly. Sure, you can throw together any three Agents and hope for the best, but the real magic happens when you tap into the deep-rooted synergies of shared factions. This system isn't just a cute lore nod—it's a game-changer, offering powerful combat buffs that turn a good team into an unstoppable force. It's like the game is whispering, 'Hey, these folks already know how to work together, so why not give them a little boost?' Let's dive into the major players shaping the battlefield in 2025.

🐇 The Cunning Hares (Gentle House)

Founded by the shrewd Nicole Demara, Gentle House operates on one simple principle: if the pay's right, the job's on. This agency, cheekily nicknamed the 'Cunning Hares' by New Eridu's underworld, specializes in taking on any odd job in the perilous Hollows.

Led by Hoshimi Miyabi—heir to a legendary martial arts family and a woman with an unshakable moral code—this organization is the city's shield against chaos. Other key operatives include the relentless Yanagi and the stalwart Harumasa. Playing a full Section 6 team feels like delivering justice personified.

Final Thoughts on Faction Synergy

So, what's the big deal about sticking to one faction? Well, it's simple. The game rewards you for it. That little bonus might be the difference between a slick victory and a trip back to the start screen. It adds a whole other layer to team-building. You're not just picking who hits the hardest; you're choosing a family, a creed, a style of fighting that speaks to you.

The beauty of Zenless Zone Zero in 2025 is the flexibility. You can absolutely mix and match from different factions and still create something awesome—that's the experimental spirit HoYoverse encourages. But there's a certain satisfaction, a unique flavor, that comes from running a pure faction team. It tells a story. Are you a law-bringer with Section 6? A profit-seeking hustler with the Hares? Or a rebel without a cause with the Sons? The choice, and the power it brings, is yours. Now get out there and build your legacy.

🔍 Pro Tip: Don't forget to cross-reference your faction choices with damage types (Ethereal, Physical, Fire, Ice, Electric) for the ultimate meta-breaking—or meta-making—team composition!
