The aura is used to identify the Digimon. On seeing them you automatically learn more about that Digimon. There are 3 types of auras: Digimon level auras, size auras and DigiClone Level auras. As of Digimon Level 46, your Digimon will start getting a different color aura. Your DigiClone aura changes as you successfully increase your Digimon's DigiClone Level. The size auras vary upon your Digimon's size. You can get a bigger size with the help of :
Miracle Fruit
Fruit of the Goddess
Mysterious Fruit.
If the Digimon reaches a certain level, it gets an aura, but will not get one unless it's Level 46 or more. The aura demonstrates the strength of the Digimon and does not affect his abilities.

The level aura will disappear when you Digivolve to Burst Mode, but will stay if you Digivolve to a Side Mega
If you have a Digimon whose hatching stage is 4/5 or 5/5, it gets above a certain percentage size from 110 to 130%, and will get a certain aura. With this aura you can see about how big the Digimon of the player is. Digimon's Aura has no impact on its abilities.
Aura at 110% ~ 114% size is Green
Aura at 115% ~ 119% size is Blue
Aura at 120% ~ 124% size is Purple
Aura at 125% ~ 130% size is Red
Digimon smaller than 110% have no aura.
If you clone your Digimon and reaches a certain level of cloning, you will have a DigiClon aura. If you have cloned more than a stat to level 4 or more, the aura of the highest cloning level will appear. Cloning your Digimon 2 or more stats to 15, will give you a Digisoul effect.
