Pre-Ultraman R/B


Rosso and Blu lose to Grigio Bone

1300 years ago, a meteor crashed down in what become Ayaka City, making a massive crater and unleashed Grigio Bone. The Ultraman siblings Rosso and Blu fought it but lost scattering the R/B Crystals with their power laying dormant in the lands of Ayaka City.

Ultraman R/B


Rosso and Blu vs Orb Dark

In the present day, Rosso and Blu return to protect Ayaka City from monster attacks and bonded with Minato brothers - Katsumi and Isami after rescuing them from Grigio Bone's assault. Although already having Taro and Ginga Crystals, others were added to their arsenal for Type Change and attack enhancements. The instigator of monster attacks, Makoto Aizen, made himself known and fought them by exploiting a R/B Crystal's power to become Ultraman Orb Dark. After training in the mountains and obtaining the Victory Crystal, the brothers avenge their initial defeat with Rosso's new form, Ground, while Blu delivers the finishing blow.


Rosso and Blu vs Horoboros

Their next great challenge came in the form of Horoboros, who was able to deflect every finisher fired at it, despite now having the power of the Orb Ring NEO. Despite their efforts, Rosso and Blu were outmatched by the monster. The Orb Ring NEO was taken from the brothers by Makoto Aizen, who transformed into Orb Dark. After Orb Dark's seeming victory against the monster, and Makoto's unleashing of Bezelb, the brothers transform again and destroy the Bezelb and prepared to fight Orb Dark, but were interrupted by the return of Horoboros, who was evolved into its Bipedal form by Saki Mitsurugi. Horoboros managed to defeat all three Ultras before returning to its R/B Crystal. The next day, Horoboros returned but the brothers finally defeat it via the Triple Origium Ray.

Ultraman Hit Song History New Generation

In this music album, Rosso and Blu were recruited by Ultraman Zero to fight against Etelgar and free the New Generation Ultras from his captivity.



  • Height: 51 m
  • Weight: 43,000 t
  • Weakness: Like all Ultras, Blu is subjected to the three-minutes limit. On occasion, he will revert back to human form even when the time is not up. It also appears that, like the Riser, the R/B Gyro has to cooldown before Isami can transform again.

Body Features

  • Color Timer (カラータイマー Karā Taimā): Blu possesses a circle shaped color timer.
  • Ultra Armor: Blu has the standard silver Ultra Armor.
  • Protectors (プロテクター Purotekutā): Blu possess protectors on his chest that represents the element of the form he is in.


Isami takes a R/B Crystal from the R/B Crystal Holder and flips out the middle horn of the crystal. He then inserts the crystal and the R/B Gyro opens. The Gyro is placed at chest level and the handles are pulled twice. Isami then thrusts the Gyro forward and pulls the handles one last time and places the Gyro on his chest, before transforming utilizing the elemental power of the crystal. When swapping crystals with Katsumi, instead of getting the crystal from the holder, the new crystal will appear and fall from above. The same sequence continues afterwards.

Orb Ring NEO-related Techniques

Through the use of Orb Ring NEO in its R/B Mode, Blu can perform finishers of Ultraman Orb by pressing its central button.

  • Origium Ray (オリジウム光線 Orijiumu Kōsen): Blu can apparently use Orb Origin's Origium Ray.
    • Triple Origium Ray (トリプルオリジウム光線 Toripuru Orijiumu Kōsen): Rosso, Blu, and the "aura of Orb Origin" fire the Origium Ray.
  • Sperion Ray (スペリオン光線 Superion Kōsen): Blu can apparently use Spacium Zeperion's Sperion Ray.
  • Zedcium Ray (ゼットシウム光線 Zettoshiumu Kōsen): Blu can apparently use Thunder Breastar's Zedcium Ray.


  • The name of his signature Aqua Strium may have been derived from the signature finishers of the Ultras who celebrate their 45th and 20th anniversaries: Taro and Agul. Taro uses the Storium (ストリウム Sutoriumu) Ray (it is sometimes spelled Strium as well no matter how little sense it makes) and Agul uses the Agul Stream (ストリーム Sutorīmu), and Blu's Aqua Strium (ストリューム Sutoryūmu) may be an amalgamation of the two former beams' named. "Strium" means nothing on its own and may very well be "Stream" made to sound slightly more similar to "Storium" but without losing its overall essence.
  • When firing the Triple Origium Ray, Blu has his left hand vertical and the right horizontal, similar to Ultraman Zearth's Speshusshura Ray as opposed to the normal + style.

    • Power: 1
    • Speed: 2
    • Defense: 1
    • Technique: 1
