Aniimo evolution: the Lumin, Gamma and Nova stages

Updated: September 22, 2026, for the version of the game live at launch.

Aniimo creatures can go through up to three growth stages – Lumin, Gamma and Nova. Most creatures can evolve, but not all of them, and that distinction gets blurred more often than it should. Each step changes a creature’s appearance and what it can do in combat, and it costs materials that are scarce early on – which is why evolving everything you catch isn’t a good idea; deciding who’s worth the investment is.

• There are three growth stages: Lumin → Gamma → Nova.
• Most creatures can evolve, not all of them – that distinction matters.
• Both where creatures show up and what they look like are governed by environment, weather, rare occurrences and time of day.
• Evolution costs materials you’ll need elsewhere – invest in what you actually play.
• Evolution stages are the main reason databases disagree on how many creatures exist.

The three growth stages: Lumin, Gamma and Nova

The progression runs Lumin → Gamma → Nova. It’s confirmed by both the official wiki and community databases, and both use the same three stages as a filter – so it’s also a practical tool for sorting the Aniilog by how far along a creature is.

Each stage changes a creature’s appearance and what it can do in combat. Specific numbers – exactly how much power increases, how stats shift – can’t be confirmed by two independent sources from what’s available, so we’re leaving them out. What does hold up is the principle: a higher stage means a visibly different look and noticeably different combat options, not just a cosmetic change.

Most creatures can evolve – not all of them

Worth calling out on its own: according to the game’s official description, most creatures can evolve, not all of them. Before you sink materials into a creature expecting three stages, know that a portion of the roster won’t go that route – otherwise you risk an investment that goes nowhere further.

Exactly which species can’t evolve isn’t something available sources reliably list. Before you put the first materials into a creature, it’s worth checking in-game whether you even see the option to evolve it at all.

What evolution changes and what it costs

Evolution requires materials and time, and the requirements grow with each stage – that principle holds consistently across sources. Specific prices, specific materials and their exact amounts, though, are thin enough in the available material that stating them here as fact would be dishonest. Anyone looking for an exact recipe of “how much of what per stage” won’t find a reliable answer anywhere right now – including here.

The practical takeaway: evolution materials overlap with other forms of investment (training, upgrades), so every decision to evolve is also a decision about what else you’re not investing in right now. That wider budget is covered in builds and skills.

When it’s worth evolving

A simple order of decisions works better than a table of numbers. Evolve the creature you actually have in your active foursome first – that’s where the investment pays off immediately. A creature you’re just collecting for the Aniilog can wait, since the materials aren’t going anywhere and will still be there once you know who’s actually earning a spot on the team.

Also keep in mind that the same materials are needed elsewhere – rating which creature is strongest overall is covered by the tier list; this is only about order, not about who’s best.

Why the same creature looks different elsewhere

According to the game’s official description, both where creatures show up and what they look like are governed by environment, weather, rare occurrences and time of day. In practice, that means the same spot can show you completely different creatures depending on the hour or the weather – and some of them may take on a different look than the one you’re used to elsewhere.

On top of evolution stages, there’s a second layer of variety – regional variants and the so-called Prismana, a weekly rotating special form some creatures take on. The exact rule for which species shows up in which specific variant, and when, can’t be pieced together into one certain answer from what’s available, so we won’t pretend otherwise – treat it as a reason to explore the world at different times and different weather, not as a guaranteed recipe. Where the individual regions actually sit is covered in the Idyll map.

Evolution and why databases disagree on creature counts

Evolution stages are the main reason different databases quote different numbers for how many creatures exist in Aniimo. If a database counts every stage as its own index entry, a single species can show up in its list up to three times – and the gap between “number of species” and “number of forms” grows into the hundreds without a single new species entering the game. The full breakdown, with the actual numbers from each source, is covered in a separate piece on the creature list and the Aniilog – here it’s enough to know evolution is the main reason why.

What can’t be undone after evolving

This is the single most practical question in this whole piece, and also the one we can’t yet answer with confidence. From what’s available, we couldn’t put together a reliable list of what’s reversible after evolution and what isn’t. Until that changes, our advice is to invest cautiously: if you’re not sure whether a specific step in-game can be undone, assume it can’t, and decide accordingly.

Once that list can be honestly built and verified directly from the game, we’ll add it here – until then, admitting the gap beats writing something that could cost you materials you can’t get back into a creature.
