Ultraman Wiki

Ultraman Gruebe[1][8][9][10] (ウルトラマングルーブ Urutoraman Gurūbu) is a Super Ultraman born from the fusion of Ultraman Rosso, Ultraman Blu, and Ultrawoman Grigio. He first appears in Ultraman R/B The Movie: Select! The Crystal of Bond.



Similar to how "R/B", which is pronounced "Ruebe" (ルーブ), is derived from the initials of Rosso and Blu, Gruebe (グルーブ) follows the same naming convention with Grigio ("G") added.


Ultraman Gruebe was designed by Masayuki Gotoh, who incorporated all the colors of Rosso, Blu and Grigio into a singular appearance to contrast Ruebe's gold and silver color. To contrast with Ruebe as well, the R/B Kourin is placed at the back of his torso.[4]

In addition to its design, Gruebe's suit already existed at the time of filming, but the filming crew decided to portray the Ultra as an entirely CGI figure. Scenes involving the Ultra crashing to a building was made by using a green log and the entire background of the green screen. Gruebe's CGI figure is said by Masayuki Gotoh to represent the image of a foreigner wearing an Ultraman suit.[4]


Ultraman R/B The Movie: Select! The Crystal of Bond

Gruebe and Geed vs Tregear and Snake Darkness

When Ultraman Tregear appeared to back up Snake Darkness, everyone was easily overpowered. Refusing to give up, the Minato siblings - Katsumi, Isami, and Asahi fused into Gruebe, activating the Makoto Crystal’s power through their family ties. Gruebe was joined by Riku, who transformed into Ultraman Geed Ultimate Final once more. Gruebe and Geed then alternated between fighting Tregear and Snake Darkness, and were eventually fighting on par with them. Finally, Gruebe destroyed Snake Darkness via the Gruebing Beam and freed Yukio Toi from the dark influence. Ultraman R/B The Movie: Select! The Crystal of Bond

Ultra Galaxy Fight: New Generation Heroes

"It's still too early to celebrate. There is a mastermind behind all this. He's the one who kidnapped Grigio to prevent you guys from becoming Ultraman Gruebe."
"But, if it's someone who knows about the existence of Gruebe...

―Zero and Geed.

The Minato brothers, aka. Rosso and Blu were involved into the fight against the League of Darkness due to Grigio's kidnapping by Ultra Dark-Killer. In the added scene of the director's cut of the full movie, a silhouetted Tregear approached the imprisoned Zero and Grigio to confirm his involvement in the kidnapping so as to prevent Gruebe's formation, as well as the Ultrawoman being a carrier of a massive light energy.

Gruebe, with the New Generation Heroes in their strongest forms

Ultraman Tregear revives Ultra Dark-Killer and Ultraman Zero Darkness after their defeat at the hands of Ultraman Ruebe, with the former growing to giant size and going berserk due to his overflowing power. The Minato siblings join the New Generation Heroes to fight Ultra Dark-Killer by fusing into Ultraman Gruebe. After the New Generation Heroes assault Dark-Killer, Ultraman Taro arrives and advises them to lend their power to the Strium Brace. Upon doing so, Ginga performs the New Generation Dynamite and delivered the finishing blow towards Dark-Killer, destroying him and the Dark Palace. The siblings separate upon the villain's defeat. Zero relayed the reason behind Grigio's kidnapping and Tregear appeared to confirm his involvement, setting up events leading to the opening of Ultraman Taiga.

Ultraman Taiga The Movie: New Generation Climax

Once the other New Generation Heroes regain their powers, they face off against Tregear, the Grimdo-possessed Taro and Tregear's monsters, with Rosso and Blu fighting against Gorothunder. After their opponents receive power ups from Grimdo, Rosso and Blu initially thought of forming Ruebe until Grigio came along and the three fuse into Ultraman Gruebe to finish off Gorothunder. Initially being trounced by Grimdo after it had absorbed Tregear, the New Generation Heroes fused with Taiga into Ultraman Reiga and defeat Grimdo. The New Generation Heroes give their parting words to the Tri-Squad and Hiroyuki and return to their home worlds. Ultraman Taiga The Movie: New Generation Climax
