Ultraman Blu

Ultraman Blu (ウルトラマンブル) is one of the two main heroes of Ultraman R/B and is the younger brother of Ultraman Rosso.

Etymology
His name means "Blue" in Italian, which refers to his main form's body color being blue.

Pre-Ultraman R/B
1300 years ago, a meteor crashed down in what became Ayaka City, making a massive crater and unleashed Grigio Bone. The R/B brothers fought it, but they lost, scattering the R/B Crystals with their power lay slumbered on the lands of Ayaka City.

Ultraman R/B
In the present day, Rosso and Blu return to fight Grigio Bone again, as as well as other monsters summoned by a mysterious enemy, through the Minato brothers - Katsumi and Isami. However, unknown to them, they were being watched by Makoto Aizen and were allowed to collect the elemental crystals for reasons unknown. After some time, they faced off against Ultraman Orb Dark, who claimed that they were unfit to be Ultramen.

Stats

 * 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): Blu possesses a circle shaped color timer.
 * Ultra Armor: Blu has the standard silver Ultra Armor.
 * Protectors (プロテクター): Blu possess protectors on his chest that represents the element of the form he is in.

Transformation
Isami takes an 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.

Trivia

 * 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) 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), and Blu's Aqua Strium (ストリューム) 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.
