Honkai: Nexus Anima Previews Bond and Evolve Systems

HoYoverse published a developer preview titled “Bond and Evolve!” ahead of the Honkai: Nexus Anima Evolution Test, laying out how the bonding and evolution loop actually works in the upcoming beta. The short version: you bond Anima by winning Nexus Battles, deepen those bonds through Evolution Challenges to unlock new forms, and pick up rarer companions through quest serendipity, the Apex Club, and partnerships with the NPCs who live alongside their own Anima. Here is everything the preview confirmed, section by section.

Key takeaways

• Nexus Battles are the core loop: win a fight against a wild Anima you meet while exploring to get the chance to bond it.
• Evolution Challenges raise an Anima’s bond and level, and clearing them unlocks that Anima’s new evolved form.
• Bonding via Quests adds serendipitous encounters, like a meteor shower that drops a rare Anima into an unexpected spot in town.
• The Apex Club lets you name a Star Anima to upgrade its skill, and repeat challenges there can bond exceptionally rare Anima.
• Bonded Anima get a keepsake photo and a custom name, and a lucky bond can land a Chromatic Anima.
• Eidos let a friend’s or rival’s Anima assist you in battle, and shopkeepers around Iia partner with Anima to run their stores.

Beta caveat: this preview covers Evolution Test content, the closed beta running starting July 9, 2026 on PC, iOS, and Android. HoYoverse says the test ends in a full data wipe, so treat every number, name, and system below as subject to change before the game actually launches.

Nexus Battles: How You Actually Bond an Anima

The preview’s headline mechanic is the Nexus Battle. As you explore Iia’s towns and countryside, you’ll run into all kinds of Anima going about their business. Win a Nexus Battle against one, and you get the chance to bond it, the same catching-through-combat loop that defines the game’s formation-based fights.

Not every encounter is equal difficulty. HoYoverse specifically calls out that some wild Anima are “exceptionally powerful,” so the preview’s own advice is to come prepared before challenging one, rather than assuming every roadside encounter is a freebie.

This builds on what the beta already established about the underlying Bond system: bonding raises an Anima’s Bond level over time, and hitting the right milestone is what makes it eligible to evolve. Our Bond guide covers how Bond Encounters and Bond levels work in more depth; Nexus Battles slot in as the specific way you start a bond with a brand-new Anima you meet in the wild.

Why difficulty varies between encounters

The preview’s warning about “exceptionally powerful” wild Anima matters more than it first looks. If Nexus Battles scale with an Anima’s rarity or level, then the toughest roadside encounters are likely gating the most desirable additions to your roster, not just padding out exploration. Until the Evolution Test goes live, the safest assumption is that you’ll want a leveled, synergistic formation on hand before chasing a wild Anima that looks unusually strong, rather than assuming every encounter is safe to walk into on a whim.

How the Five Bonding Methods Compare

Between this preview and what the beta already documented, there are now five distinct ways to add or upgrade an Anima. Here’s how they stack up against each other:

Method	How you trigger it	What you get
Nexus Battle	Win a fight against a wild Anima found while exploring	A chance to bond that specific Anima
Evolution Challenge	Complete objectives with an already-bonded Anima	A deeper bond, a level increase, and an unlocked evolved form
Bonding via Quests	Talk to NPCs and follow story prompts around town	A serendipitous bond, sometimes with a rare Anima
Apex Club	Name a Star Anima and clear club challenges	An upgraded skill for your Star Anima, plus a chance at exceptionally rare Anima on repeat clears
Shopkeeper partnership	Assign a bonded Anima to help an NPC’s business	A stronger relationship with that shopkeeper, not a new Anima

Reading the table left to right, the methods roughly track a progression: Nexus Battles and Bonding via Quests are how you meet new Anima early, Evolution Challenges are what you do with the ones you’ve kept, and the Apex Club is the repeatable loop you graduate into once you have a formation worth investing in. Shopkeeper partnerships are the outlier, a way to keep using Anima you’ve already bonded rather than a way to get new ones.

Evolution Challenges Unlock New Anima Forms

Once you’ve bonded an Anima, Evolution Challenges are the next step. The preview describes them as objectives built around deepening your bond and raising an Anima’s level, and clearing them unlocks “all-new forms” for Anima that are capable of evolving.

That framing lines up with how evolution already works elsewhere in the beta: it’s bond-driven rather than a pure stat grind, so an Anima’s evolved form is presented as a reward for the relationship, not just a resource dump. Our evolution guide breaks down how bond milestones translate into evolved forms and what Chromatic variants add on top of a normal evolution.

The practical read for Evolution Test players: don’t spread challenge attempts thin across your whole roster. Concentrate Evolution Challenges on the two or three Anima you’re actually fielding, since those are the ones whose evolved forms will matter in your formation.

Bonding via Quests Adds Serendipity to Exploration

Not every bond starts with a fight. The preview highlights Bonding via Quests, small story-driven moments that surface while you talk to NPCs around town. One example shown is a meteor shower: chase the falling star, and you find a “cute little Anima” waiting in an unexpected spot.

This is a deliberate counterweight to the combat-first Nexus Battle loop. It gives exploration and dialogue their own payoff, rather than making every worthwhile Anima gated behind a fight, and it matches the game’s stated goal of making the world “feel more real, more natural, and more alive.”

If you’re the type of player who talks to every NPC and reads every dialogue prompt, this is your system: the preview frames these encounters as tied to conversations and exploration rather than anything you can grind on demand. For a broader look at how exploration mechanics tie together, see our exploration guide.

Apex Club and Star Anima: The Gameplay Rewards Loop

The Apex Club is one of “a number of different gameplay modes” the preview name-drops, and it’s built around designating one Anima as your Star Anima. Naming a Star Anima unlocks its potential, letting you upgrade its skill and get more power out of it in battle.

Clearing multiple Apex Club challenges goes further: HoYoverse says you can bond “exceptionally rare Anima” as a reward for repeat completions. That makes the Apex Club look like the beta’s dedicated endgame-style loop, a system for players who’ve already built a formation and want a reason to keep running content with it.

The preview is careful to add that “there are even more ways to bond Anima waiting to be discovered,” which reads like a signal that the Apex Club and Nexus Battles aren’t the only acquisition loops HoYoverse is planning to reveal.

Chromatic Anima, Photos, and Naming Your Companion

Beyond the mechanics, the preview leans into the ownership side of bonding. Forming a bond with an Anima lets you capture the moment with a special photo and give it its own name, and with enough luck, that bond can produce a rare Chromatic Anima instead of the standard version.

In battle, the preview says you’ll be able to “deploy a wider variety of Anima” to trigger different Aspect effects as you level up, which ties bonding directly into team-building rather than leaving it as a purely cosmetic system. Outside of battle, an Anima’s abilities help you traverse the world and solve puzzles while exploring Iia, echoing what’s already documented in our Aspect synergy guide.

Eidos: Your Friends’ Anima Join the Fight

The people around you in Iia, including rivals, have bonded their own Anima, and the preview introduces Eidos as the way those relationships show up in combat: a friend’s Anima can arrive mid-battle to lend a hand.

HoYoverse specifically calls out Blade and Bladehound’s “flawless teamwork” as a preview of the kind of opposition you’ll face, which tracks with Blade’s established role in the roster. Our Animaster guide has more on Blade and the rest of the cast whose bonds with their Anima shape how they fight.

Anima at Work: Shopkeepers and Partner Anima

The preview’s last reveal is more slice-of-life than combat: many shopkeepers around Iia work alongside partner Anima to run their businesses. The examples given are a coffee shop with “Kaffiends’ seal of approval” and a food stand serving fries a Frigull has personally selected.

You can also assign your own bonded Anima to assist these shopkeepers, which HoYoverse says helps them “manage their stores more effectively and expand their businesses.” It’s a small system, but it reinforces the preview’s broader theme: bonding an Anima is meant to feel like gaining a companion that’s woven into the world, not just a stat block added to your formation.

What This Preview Means for Evolution Test Players

Taken together, the preview confirms at least five distinct ways to end up with a new or upgraded Anima: Nexus Battles, Evolution Challenges, Bonding via Quests, the Apex Club, and NPC shopkeeper partnerships. HoYoverse’s own closing line, “what you’ve seen here is only a small step,” suggests more systems are still to be revealed before or during the test.

If you’re signed up for the closed beta, the actionable takeaway is to treat bonding as an ongoing habit rather than a one-time catch: talk to NPCs for quest encounters, fight wild Anima you cross paths with, and funnel your Evolution Challenge attempts into the handful of Anima you actually plan to run. Check our Evolution Test sign-up guide if you still need to register, and our Evolution Test FAQ for dates, device requirements, and data-wipe details.

Questions the preview leaves open

HoYoverse didn’t say how Nexus Battle difficulty scales, whether Evolution Challenges are timed or repeatable, or how rare a “rare Anima” from Bonding via Quests actually is compared to an Apex Club reward. It also didn’t confirm whether Star Anima status can move between Anima freely or locks in once chosen. Expect these specifics to surface once testers actually get hands-on time on July 9, and expect our guides to update as soon as they do.

Bottom line

Bond and evolve harder in the Evolution Test than they did in the previous beta: wild Anima now come through Nexus Battles, evolved forms come through Evolution Challenges, and the Apex Club adds a repeatable endgame reason to keep at it. None of it is locked in until the test goes live on July 9, so bookmark this preview, keep an eye on our news for follow-ups, and build your early formation around Anima you’re willing to invest bond time in.
