| Evolution Icon |
- This is outlined an additional time for Ultimate evolution MAX.
- It is officially also called "evolution ball". It is an illustration and design rule that has been in existence since DM-02 Master of Evolution. Some creatures have this icon as part of their body, such as Niofa, Horned Protector.
- The amount of icons represented in the illustration are the same number of creatures required as an evolution source, but some cards such as Saint Bolshack, Spiritual Dragon have ignored this.
