Boss and rare encounter captures: Alphas and Umbrals
Alphas sit near a 10% catch after you beat them, and Omegas can't be caught at all. Here is what improves the odds, what a catch costs, and how rare Umbrals are.
The short version
- You can't catch an Alpha Aniimo mid-fight. Defeat it first; that is what opens the capture chance.
- With common Aniipods an Alpha or boss catches at roughly 10% per attempt, and base rates for Alphas typically run between 8 and 12 percent.
- The Aniipod Ultra is the top of the standard line and the usual answer for Alphas like Stellarys, but whether it truly guarantees a catch is not settled.
- Omega Aniimo cannot be captured, so don't spend Primegy or pods trying.
- Umbral Aniimo have a base open world encounter chance of approximately 1 in 3,000, and wild surges triggered by ecosystem nurturing can also bring them out.
Aniimo's rare catches all share one rule: you fight first and throw second. Alpha Aniimo, the area bosses people search for as "aniimo alpha", only become catchable once you have beaten them in combat. Legendaries work the same way, with a stricter pod and only one chance.
Umbral Aniimo are different. They aren't bosses. They are rare variants that turn up in the open world, and the hard part is finding one, not beating it.
This page covers when each of these can be caught, what your odds are with each pod, and which of them you should never waste a throw on.
When an Alpha Aniimo becomes catchable
You can't capture an Alpha area boss during the fight. Wild Alphas become catchable once they have been defeated in combat, and beating one gives you your opportunity to catch it. After the fight, any Aniipod can be thrown.
The throw costs more than the pod. Catching an Alpha Aniimo spends Primegy, Aniimo's energy resource. Primegy regenerates over time and is separate from the stamina bar you manage in combat, so a long boss fight doesn't drain what you need for the catch. Running out of Primegy is its own problem, though.
One rule saves you wasted effort: Omega Aniimo cannot be captured. Beat them for whatever else they give you, and keep your pods in the bag. Finding Alphas and fighting them has its own guide on this site; this page is about the throw.
Your odds with common pods and the Aniipod Ultra
Common pods are a gamble against bosses. Boss and Alpha Aniimo have low base catch rates, around 10% per attempt with common Aniipods. The exact figure depends on the Alpha, typically between 8 and 12 percent with standard capture devices. Expect several throws and plenty of misses.
The Aniipod Ultra is the top tier of the standard Aniipod line and improves your odds on tougher targets. Stellarys is the usual example. You can catch it with a lesser Aniipod, though not reliably, while defeating it and then throwing an Aniipod Ultra secures a guaranteed 100% capture. The Ultra is also credited with a 100% catch rate on any Aniimo, Alpha bosses and Umbral Aniimo included, and with ensuring at least Elite potential on a wild catch.
That is the working assumption. Whether it holds everywhere is not settled. No official guarantee is stated for the Ultra, and the assured catch may belong instead to the Sparkling Cube, an upgraded version of the Aniipod Ultra. The practical reading is simple: on a boss you care about, the Ultra is the pod to throw, and common pods are a roll of roughly one in ten. Throw mechanics in general have their own page.

Winning the fight you have to win first
Because the catch only opens after a defeat, the fight is the real gate. Enemies use an aggro system: they concentrate their attacks on whichever Pathfinder holds their aggro rather than spreading damage across the party. Plan around who takes the hits, not around everyone taking a share.
That is why late-game and boss encounters need a balanced team with healing and support, not only DPS. Break-role Aniimo earn a place here too. They specialise in disrupting enemies and breaking guard or poise, which creates the openings your damage dealers need. Pawney is one name worth knowing; it is effective in Alpha boss dungeon battles as well as Egg Heist and PvP.
Umbral Aniimo: rare spawns in the open world
Umbral Aniimo, also called Umbra Aniimo, spawn naturally at random and at a low rate while you roam the open world. Radiant Aniimo variants work the same way. Both can be encountered and captured like any wild Aniimo.
The base encounter chance for an Umbral in the open world is approximately 1 in 3,000. That is low enough that you won't stumble into one on purpose, which is why the second route matters: Umbrals can appear during wild surges triggered by ecosystem nurturing. The nurturing system itself is covered in its own guide.
Don't assume an Umbral will be a first-stage creature. Evolved and fully evolved creatures can be met directly in the wild in Umbral form. When one does appear, this is the moment the Ultra is for, since it is credited with a 100% rate on Umbrals as well as bosses.

Legendaries: one encounter, one purpose-built pod
Legendary Aniimo tighten the Alpha rules. You get a one-time encounter, you must defeat the Legendary in battle during it, and only then can you capture it, with a purpose-crafted Legendary Aniipod rather than anything from the standard line.
Irisalis is the example. You bond it by throwing a crafted Legendary Aniipod at it after defeating it in its story encounter. Have the pod crafted before you start that fight. Irisalis has a full guide of its own.
Where to start
Carry an Aniipod Ultra and spare Primegy into any Alpha fight you want to keep, and bring a team that can survive it, healer included. Save common pods for targets where a one in ten roll is acceptable. Never throw at an Omega, and craft the Legendary Aniipod before you start a Legendary's only encounter.
