Attack Ring (AR): Advance Defenser
- Weight: 18 grams
Advance Defenser has two metal "rollers" which are supposed to help defend against attacks, but this is negligible. This AR also has two wings that come to a point and have shallow slopes that provide minor Upper Attack, though they are too light and gradual to be effective. However, although outclassed, this part can be used for Smash Attack customizations.
