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.


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


Pre-Ultraman R/B


Blu in the past

Grigio and her brothers Rosso and Blu were a trio of orphan siblings born on the war-torn Planet Sanja (惑星サンジャ Wakusei Sanja), having been raised along with other orphaned children by Bakubarba (バクバーバ Bakubāba) in a place known as the House of Bakubarba (バクバーバの家 Bakubāba no Ie). The siblings have elite skills in the fields of killing and other illegal activities, which makes them useful tools for Bakubarba, who frequently sends them out on missions. Having no records and no relatives, they were also easily disposable should they fail their job.

The youngest sibling, Grigio, starts to have doubts in killing others and her way of life though each time she only needed to be advised by her brothers and Bakubarba to get back to work. One day, Bakubarba was contacted by Mr. Largo (ラルゴ氏 Rarugo-shi) to kill the monster Nero (ネーロ Nēro), the guardian god of the Bosco Tribe (ボスコ族 Bosuko-zoku) on Forest Planet Dontak (森林惑星ドンタク Shinrin Wakusei Dontaku). Bakubarba sends the trio via spaceship. When the siblings search a dark forest on Planet Dontak, Grigio encounters Bianca (ビアンカ Bianka), a woman who is about to be sacrificed to Nero, but she seems happy, which Grigio cannot understand. The siblings later interrupt the sacrificial ritual to combat Nero, but Grigio tries to convince Bianca to turn against her fate, much to her brothers' dismay as Nero had not yet fully emerged, while angering Nero who tries to kill the siblings. Bianca instead allows Nero to transplant its weak point into herself, so the three siblings have no choice but to kill her along with the monster. The incident left Grigio traumatized. After the siblings leave, the mercenary unit Largo Protege’s (ラルゴ子飼い Rarugo Kogai) bombs the Boscos with napalms, so that Mr. Largo is able to "modernize" the planet and take the rare minerals there for himself.

Rumours about the three siblings spread and they are constantly under attack by gangs whose members they killed before. Under Bakubarba's advice, they escape to Planet Alhara (惑星アルハラ Wakusei Aruhara), a relatively obscure planet. The people there face frequent water shortages during farming, so the siblings decide to help them by digging up water from underground. The siblings discover a new way of life, which was to give and not to take. For the first time in a long period Grigio was happy, and would like to make this planet her new home. Unfortunately, the reputation of the three siblings means that they would eventually be found and the people of Alhara will suffer because of them, so they have to leave again. They go to Planet Alcatraz (惑星アルカトラズ Wakusei Arukatorazu), which is full of criminals. In a bar, Grigio overhears a rumour about the Warrior's Peak of Planet O-50, and wanted to obtain the power there to become an Ultraman so that she could achieve peace without sacrifice. However, her brothers dismiss her, saying that it's just a fairy tale.

While escaping from the Balsas Gang (バルサス一味 Barusasu Ichimi), they crash land on Planet O-50, near the Warrior'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 Warrior'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 Reugosite, 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 theit 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 Reugosite 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 whormhole was opened and they were all sucked into it, and they ended up near the planet Earth, which Reugosite 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

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.The World is Waiting for MeIn the Name of Ultraman

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. Despite their efforts, Rosso and Blu were outmatched by the monster. Defeated, the Orb Ring NEO was taken from the brothers by Makoto Aizen, who transformed into Orb Dark once again. 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. She cheered them on and, hearing her prayers, the Orb Ring NEO returned itself back to the two Ultraman brothers, who used the Triple Origium Ray to finally defeat Horoboros.The Minato Family HolidayAizen's FrenzyWhat We Should Protect

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.Who Are You?Enshrined by Extremity

Reugosite's Arrival


Rosso and Blu Vs Grigio Regina

Unable to convince Saki out of her plan, 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. Surprisingly, even the Ruebe Vortex Buster was ineffective against Grigio Regina and he was defeated.The Crystal of Destruction

After regaining their Gyros from Ushio, the Minato brothers transformed into Rosso and Blu to defend Grigio Regina from being shot by Reugosite, countering the Genesis Requiem by firing their signature Ultra Beams, though they were overcome. As Reugosite prepared to fire at them once more, Grigio Regina stepped in the way and was instantly killed before them.I Am Happy Rosso and Blu charge at Reugosite and transform into Ruebe but they are soon overpowered and split.

Seeing that they were about to be finished off, Mio locked the Gyros and canceled their transformation in the nick of time to dodge the Genesis Requiem. Rosso and Blu reappeared again after the brothers talk to their mother but they were once again beaten and almost finished off, but just as they were hit, they fused into Ruebe and changed the future that Mio saw, giving her faith in her sons and convinced her to stop her plan.

Katsumi and Isami suddenly find themselves transported to the Land of Light in their Ultra forms, performing their handshake while being unaware of what was even going on. They met the 6 Ultra Brothers, who welcomed them to the Space Garrison Headquarters. Taro explains that the Space Garrison 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. Hearing this, the Minato brothers immediately fly off to search for their sister, without giving a chance for Taro to explain further. Ultra Galaxy Fight: New Generation Heroes

  • 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 cool down before Isami can transform again, however, it is not as long as the former.

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.

  • Designer: Masayuki Goto.
  • 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 (sometimes spelled Strium Ray) 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.
  • According to Makoto/Cereza's observations and analysis, Isami/Blu's stats are, as of episode 8:
