Ultraman Blu (ウルトラマンブル, Urutoraman Buru) 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.


Pre-Ultraman R/B[]

While Rosso, Blu, and Grigio were escaping from the Balsas Gang (バルサス一味, Barusasu Ichimi), they crash land on Planet O-50, near the Crusader's Peak, which Grigio believes is fate. They meet Frau (フラウ, Furau) in a hut at the base of the mountain, and she tells them they would need oxygen inhalation devices (酸素吸入装置, Sanso Kyūnyū Sōchi) to climb up the mountain. The Balsas Gang appears and takes Frau hostage, but the three siblings beat them. Unfortunately, they unleash Margodon, who they have no chance of beating. They decide to put the only oxygen inhalation device on Frau, not wanting any third party to get hurt because of them, and climb up the Crusader's Peak, but were stuck in a dilemma whether to attack from there or climb down the other side. Suddenly, the Ring of Light appears to them, giving them the Gyros and R/B Crystals, which they use to transform into Ultraman Rosso, Ultraman Blu and Grigio Bone to defeat Margodon, the Balsas Gang and rescue Frau.

They go on more adventures and gather more R/B Crystals, and eventually become recognized by the Interstellar Alliance. However, Grigio cannot understand why she transforms into a monster. They are sent back to Planet Sanja to inspect on Bakubarba, but discover that the House of Bakubarba has become a child trafficking hub. Bakubarba tries to guilt-trip the siblings, saying that after Mr. Largo acquired Planet Dontak, he sold it off to the Interstellar Alliance, who are also profiting off it. Grigio gets fed up and kills Bakubarba after being taunted. The Balsas gang hears about this and unleashes the monster Fearmonger (フィアモンガ, Fiamonga) to kill the siblings. The brothers try to fuse the crystals of light and darkness into a new power, but they fail because they do not connect with Grigio's wishes. Eventually, Rosso, Blu and Grigio defeat Fearmonger without making any sacrifices.

The siblings are then dispatched to Planet Gion (惑星ギオン, Wakusei Gion) to help Zarra Tribe (ザーラ族, Zāra-zoku). Alien Egon Ciel (エゴン星人シーレ, Egon Seijin Shīre) created the Murderous Robot Weapons Barrigator 1 and 2 (殺人ロボット兵器バリゲー ター1号・2号, Satsujin Robotto Heiki Barigētā 1-gō 2-gō) to kill everyone there so that he could take the rare metals for himself. The siblings try to convince the people to evacuate, but they do not listen, saying their god will protect them. The boy Verte (ヴェルテ, Verute) shows Grigio a book about a legend of a red dragon, who is said to bring destruction. Grigio becomes Grigio Bone to scare everyone away just before Barrigator 1 arrives to fight Ultramen Rosso and Blu. Barrigator 2 suddenly appears before the escaping people, who fight back after seeing Verte step up. Grigio created the Attack crystal from this event through their combined will and became Grigio Regina, who easily defeated Barrigator 2 and Ciel along with it. Grigio is exhausted and turns back into herself, and is taken care of by the Zarra people, who bow to her after she awakens. Rosso and Blu meet up with their sister after defeating Barrigator 1.

The Ring of Light calls the siblings to Urban Planet Nepta (都市惑星ネプタ, Toshi Wakusei Neputa) to defeat the rampaging Leugocyte, who had its genes tampered with by a certain blue Ultraman. The siblings used their Gyros to turn the gaseous monster into a solid, but their Gyros' output is weak and the monster is stuck in an intermediate form, which destroys the planet. Unable to sit and watch, Blu attacks, ruining the plan. Rosso and Grigio have no choice but to attack as well. Freezing the monster using the Water and Wind crystals, they throw Leugocyte into space but it regains its gaseous form. Grigio Regina is knocked back down into King and then to Bone. Due to their intense battle, a wormhole was opened and they were all sucked into it, and they ended up near the planet Earth, which Leugocyte sought to drain the life energy out of and then destroy.

However, the siblings lost the battle and crashed down towards Earth as a meteor, in a place that became known as Ayaka City, spreading Ray Energy throughout 1300 points of the Earth as a result of the impact. Grigio grieved over the loss of her brothers, who had died and become scattered as R/B Crystals. Ultraman R/B Novel: The Blue-Eyed Girl Whose Name is Gray

Battle Against Horoboros[]


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.

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 then 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 and the brothers faced yet another tough battle, with all their tactics failing. They were on the losing end until Asahi arrived.

Ruebe vs Grigio King

After that, they were faced by a vengeful Cereza, who transformed into Grigio King via Saki's Gyro. The brothers try their best but they are unable to defeat Grigio King, exhausting all of their techniques. As a final resort, they tried to use Ultraman's and Ultraman Belial's Crystals, but to only be rejected by them. The brothers return the next day after a short recovery period, but even with a new strategy, they were unable to defeat Grigio King until Asahi reminded them of their mother's words - that when the two of them are together, they can do anything. With that, they managed to unlock the power of Ultraman's and Belial's Crystals, which allowed them to fuse into a more powerful being known as Ultraman Ruebe, who fought Grigio King and finally destroyed it.

Unable to convince Saki out of her plan to destroy the Earth along with Leugocyte, Katsumi and Isami transform into Rosso and Blu to stop her from going back to Aizen Tech, having transformed into Grigio Regina to do so. Not wanting to kill her, Rosso and Blu were careful not to hurt her too much, though Saki did not reciprocate their sentiments. Unable to do much individually, the brothers fused into Ultraman Ruebe.

Taro explains that the Inter Galactic Defense Force sent Zero to protect Ultrawoman Grigio, who was being targeted by Ultra Dark-Killer, who Taro once defeated. He says that contact with Zero was lost, so they had guessed that Grigio had been kidnapped.

However, Tartarus uses the gathered Devil Splinters to empower Reibatos, who recreates the Giga Battlenizer, and fuses Gina with the souls of her brothers to create Gua Spectre before he dies of an overdose. Gua Spectre's new perfect form proved to be too powerful, forcing the New Generation Heroes to fuse into Ultraman Reiga, who easily defeats Gua before defusing into his components.

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.
