- Rock Aries ED145D WBBA Ver.: DJ's Rock Aries is a premium edition WBBA Specialty noted by Madoka. It is a Defense-Type Beyblade, and very similar to Rock Aries ED145B. Although many of the parts appear to be dark yellow or brown, they are actually translucent black, but appear as faintly yellow or brown because of the effect light has on translucent black plastic.
- American DJ's style of clothing is based on Uncle Sam, an iconic symbol of the United States during World War II, at which time, the United States was at war with Japan. The rivalry between American DJ and Blader DJ (who is the DJ from Japan), may be a subtle reference to World War II, and the hostilities between those two countries.
