The pieces of this card's armor change into the form of a crescent moon.
This card's ability to change its Level from 4 to 8 is similar to how Quattro used Level Doubler in the anime, as every time he used it, he Targeted one of his Level 4 Gimmick Puppet monsters to double its Level to 8.
The said ability may also be reflected in its name because a radius is half the diameter of a circle or sphere. Doubling that would make the full diameter of the said shapes.
