R／B Crystals

The R/B Crystals (ルーブクリスタル) are the collectible items in Ultraman R/B. When not in use, they are stored in the R/B Crystal Holder and/or R/B Crystal Collection Case.

Ultraman R/B
1300 years ago, Grigio Bone and the two Ultras, Blu and Rosso crashed into Earth. The Ultras however dispersed into R/B Crystals upon impact while said monster went on a rampage unopposed.

In modern time, the crystals are used by Katsumi Minato and Isami Minato, the human hosts of the aforementioned Ultras, and Makoto Aizen himself who is plotting against the heroes.

Functions
Each crystals function differently according to its power containment:
 * Ultra: The R/B Crystals that contain the powers of Ultra Warriors allow Rosso and Blu to access different forms based on elemental powers. Additionally, they can also channel the crystals' powers through their R／B Sluggers. For this to work, the Minato brothers need to flip its horns based on their Ultramen counterparts.
 * Kaiju: So far, their only ability is to summon a Kaiju based on its corresponding R/B Crystal. Makoto shows no necessity to flip its horns, since he himself is not an Ultraman.

Attributes
The attributes have returned since Ultra Fusion Cards and like its counterpart, it symbolize their specialities and association from their respective elements. However, each Crystal's elemental attribute is unique to itself, and the elemental powers of many characters were swapped around, or were replaced by new ones.
