Ultraman Blu is one of the two main Ultra Heroes of Ultraman R/B, and is the younger brother of Ultraman Rosso and older brother of Ultrawoman Grigio. In the past, he used to have a human form of the same name, but the power of Ultraman had been passed onto Isami Minato in the present day. He specializes in close and mid-range combat.

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

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.

Aqua is Blu's main balanced form that focuses on agility and continuous attacks. It uses Ultraman Ginga's R/B Crystal, granting him the element of water. This form debuts in episode 1.
