Rarity
Rarity is a tier rating carried by every Creo in EvoCreo and EvoCreo 2, and in EvoCreo 2 by every item and trait as well. It is shown as a colored badge, such as 
Rare or 
Prime.
Both games use rarity, but on different scales and for different purposes. EvoCreo has five tiers, and a Creo's tier sets its catch rate, experience yield, flee chance and level-up curve outright. EvoCreo 2 has ten tiers, which act mainly as a category label.
Rarity does determine how often a Creo is found in the wild, but not directly. Encounter chance is worked out from a per-area spawn weight that is set taking into consideration the rarity tier of the Creo.
EvoCreo
| Tier | Base catch rate | EXP base | Flee chance | Creo |
|---|---|---|---|---|
 Common |
100 | 20 | 0 | 17 |
 Uncommon |
75 | 50 | 0 | 49 |
| Rare |
40 | 90 | 1 | 54 |
 Ascendent |
10 | 150 | 2 | 44 |
| Prime |
1 | 250 | 3 | 8 |
Creo rarity is what gives it a catch rate, an experience yield, a flee chance and a level-up curve..
A higher base catch rate makes a Creo easier to capture, so a Prime at 1 is close to uncatchable by ordinary means. Flee chance runs upwards from 0, and only Rare and above ever flee a wild battle.
Shiny
| Color | Chance | Effect |
|---|---|---|
| Shiny | 0.25%, or 1 in 400 | Appearance only |
| Genetically Modified (GM) | — | 1.75× bonus to stats |
GM is not technically a shiny and is not found in the wild. It marks a genetically modified Creo. Bringing a level 100 rank 10 Creo to Colmena in Plantae Village modifies it, improving its stats and altering its color.

Only the first seven tiers appear on wild Creo. Mega Prime covers just Lesser Nebu and Lesser Ultimus, Nebulous just Nebu and Ultimus, and none of these four can be met in the wild. Mystic Prime is unused: no Creo, item or trait carries it.

The game uses both words, shiny and pattern, for this. Characters in the Muhit school talk about patterns and shinies interchangeably.
An Elite shiny is not found in the wild and has to be applied with a Paint Spray Elite.
Note: Achievements and missions that ask for "rare creo" can mean shinies rather than tiers.
