The R/B Crystals (ルーブクリスタル Rūbu Kurisutaru) 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.


Pre-Ultraman R/B

In order to save Frau from the Balsas Gang and their monster Margodon, Grigio and her brothers climbed up the Crusader's Peak of Planet O-50, where they received the Gyros and R/B Crystals from the Voice of Light. Their initial crystals were those of Taro, Ginga and Grigio Bone, but they received more from each battles and missions. Incidentally, their home planet Sanja had crystals of Ultraman and Belial due to their representative nature of endless conflicts between light and shadow. Despite their massive powers, the brothers fail to use it as their hearts are not linked to their sister.

1300 years ago, Grigio (as Grigio Bone) alongside Ultraman Blu and Ultraman Rosso crashed down towards Earth after being defeated by Leugocyte. The Ultras dispersed into R/B Crystals and left their sister behind, who mourned over their deaths.

Ultraman R/B

In modern times, 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.

The crystals of Ultraman and Belial were shown to be in the hands of Saki Mitsurugi, who later gives them to Asahi Minato. Although Katsumi and Isami previously failed to harness the crystals' power while fighting Grigio King, they were able to do so during the rematch and transform into Ultraman Ruebe via the Kiwami Crystal.

Although Mio Minato succeeded in sealing Leugocyte into a R/B Crystal, Saki claimed the crystal while revealing her intentions of summoning Leugocyte to destroy it alongside herself and the Earth. Leugocyte’s crystal activates itself after Ruebe was defeated by Grigio Regina, cancelling out Saki's transformation and assume its true form via Saki's Gyro. Once Asahi realized her origins being the embodiment of the Makoto Crystal, she transformed into it after defending her brothers and they finally destroyed Leugocyte via the Shin Vortex Buster.


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. In certain cases however, there are crystals which that yield different results upon activation. One such example being the Orb Origin Crystal, which transforms into the Orb Ring NEO. While the canon status of this situation is still debatable, the second stage show of Ultraman Festival 2018 revealed that energies from mankind's cheers can summon an Ultra Warrior (Tiga in this case) from any R/B Crystal.
  • Kaiju: These crystals so far only representing the embodiment of a Kaiju. Through the Gyro, they can either be summoned or transformed from their user. A summoned Kaiju would only be regressed to their crystals should they be defeated or commanded to retreat, whereas transformed version allows their user to revert at will. Makoto shows no necessity to flip the crystals' horns, since he is not an Ultraman by natural means.


Each Ultra and Kaiju R/B crystal has an attribute unique to itself, which symbolizes their association with their respective elements. For a full list, please see R/B Crystals/List of Crystals.

Known Existing Crystals




  • Blank crystal


  • The R/B Crystals' outer frame resembles both Rosso, Blu and Ultrawoman Grigio's Color Timers. When designing Ultraman Fuma, Masayuki Gotoh adopted this Color Timer design towards the former due to sharing the same origin (Planet O-50).
  • The damaged Orb Origin Crystal's outer frame resembles the X Devizer after being struck by Zaigorg's red lightning beam.
  • It's worth noting that the crystals which depict pictures of their respective Ultra Warriors don't actually contain the Ultra's powers. This is in contrast to the former New Generation items.
    • When asked how the Crystals correspond to the various Ultra powers, Masayuki Gotoh (the head designer for the New Generation Heroes) replied with "It's complicated".[1]
  • Unlike most other R/B Crystals, the Kiwami Crystal only has the face of Ruebe instead of an entire upper body shot. The horns are also folded forwards instead of backwards, which form the entire face while hiding the kanji for Kiwami.
    • The Kiwami Crystal has the face of Ultraman Ruebe on the back of its middle horn and his name written in the language of M78 on the back of the side horns.
  • Exclusively in the Ultraman R/B novel, crystals depicting monsters are called Kaiju Crystals (怪獣クリスタル Kaijū Kurisutaru). On this wiki, they are not given a separate page due to them not being called those in-show or in merchandise, unlike the Kaiju Cards and Kaiju Capsules before them.
