Ultraman Ruebe

"The two of us..." "Can do anything!"

- Katsumi and Isami, unlocking the power of Ruebe

Ultraman Ruebe (ウルトラマンルーブ) (named "Ultraman R/B" by some sources) is the titular Ultra of Ultraman R/B, debuting in episode 15. He is formed from the fusion of Ultraman Rosso and Ultraman Blu.

Ultraman R/B
During Grigio King's second attack, Ultraman Rosso and Ultraman Blu attempt to defeat the monster but even their Flame-Aqua Hybrid Shoot was ineffective against its tough hide. The brothers once again try to use the Ultraman and Belial Crystals, to no avail, until Asahi Minato reminds her brothers that they can do anything when they're together. WIth this encouragement, they are finally able to use the powers of the two crystals, which merges with their other crystals and spawns the Kiwami Crystal, used to transform into Ultraman Ruebe, easily defeats Grigio King. The brothers continue to use the power of Ruebe to fight off other threats.

Transformation
1= "The power of brothers become one!"

- Transformation announcement w/ Kiwami Crystal

2= "Enshrined by extremity! The golden universe!!"

- Ruebe's transformation catchphrase

The sequence begins as both brothers take the Ultraman and Belial Crystals respectively, flip out the horns of the crystal and then insert the crystal as their R/B Gyro opens. The Gyros are thrust forward and the handles are pulled thrice. This causes both crystals to merge along with the Taro, Ginga, Tiga and Victory Crystals as well to form the Kiwami Crystal.

Katsumi flips all the front horns of Kiwami Crystal while Isami stands by his side, revealing its Kanji and insert it to his Gyro. He then thrusts the Gyro forward and pulls the handles one last time and places the Gyro on his chest, before the two siblings transforms into Ruebe and the Ultra emerges with his left hand facing the screen. They no longer need to use the Ultraman and Belial Crystals after their first merger.

Abilities

 * Strength: Ruebe is naturally strong, able to physically hurt Grigio King in hand-to-hand combat.
 * Acceleration: Ruebe is able to accelerate to high speeds, used in conjunction with his R/B Kourin to land a succession of slashes.
 * Barrier: Ruebe summons an energy barrier from his hand. It is strong enough to easily withstand Grigio King's Flame Emission, which previously countered the Flame-Aqua Hybrid Shoot.
 * Bullet Destroy: Ruebe catches an energy bolt in his hand and destroys it without any ill effect.

Weapons

 * R/B Kourin (ルーブコウリン): Ruebe's personal weapon, accessed through the use of the Kiwami Crystal. It is summoned from the golden ring around his Color Timer.
 * Buzzsaw Slash: After switching the R/B Kourin into Rosso Mode (ロッソモード), the blades on the weapon can rotate and act as a buzzsaw cutter.
 * Dashing Slash: After switching the R/B Kourin into Blu Mode (ブルモード), Ruebe can accelerate to high speeds and land multiple slashes on the opponent.
 * Deflection: Using the R/B Kourin, Ruebe can deflect incoming projectile attacks.
 * Beam Reflect: The R/B Kourin is capable of absorbing an enemy's energy beam and redirecting it back towards them.
 * Vortex Buster (ボルテックバスター): A seemingly less powerful variant of Ruebe Vortex Buster. It is performed by inserting any R/B Crystal on the weapon.
 * Ruebe Vortex Buster (ルーブボルテックバスター): After switching the R/B Kourin into Rosso Mode (ロッソモード) while using the Kiwami Crystal, Ruebe fires a destructive, rainbow-colored, tornado-like beam from the radius of the R/B Kourin.
 * Shin Vortex Buster (シンボルテックバスター): An even more powerful version of the Ruebe Vortex Buster, using the Makoto Crystal (in its closed form) in place of the Kiwami Crystal.
 * Kourin Shot (コウリンショット): A seemingly less powerful variant of Ruebe Kourin Shot. It is performed by inserting any R/B Crystal on the weapon.
 * Ruebe Kourin Shot (ルーブコウリンショット): After switching the R/B Kourin into Blu Mode (ブルモード) while using the Kiwami Crystal, a buzzsaw slashing projectile is shot from the R/B Kourin.
