Samurai Gattai ShinkenOh (侍合体シンケンオー Samurai Gattai Shinken'ō?) is formed when the Shinkengers write the kanji for "unite" (合, gō) to make their Origami to combine. It is armed with the Daishinken (ダイシンケン, Great Divine Sword) and a giant Secret Disk that doubles as the Secret Shield (秘伝シールド, Hiden Shīrudo). The Shishi Origami head on its body can breathe fire in the Lion's Blaze Roar (獅子火炎哮, Shishi Kaen Kō) attack, takes to the air with the Dragon Rising Leg (龍昇脚, Ryū Nobori Kyaku), and separate from the Kame Origami to execute the Turtle Heavenly Fist (亀天空拳 ,Kame Tenkūken). Both of ShinkenOh's arms can also fold back up to unleash a beam attack. Its finishing attack is the Daishinken Samurai Slash (ダイシンケン侍斬り, Daishinken Samurai Giri). It can combine the four support Origami by performing Samurai Armaments (侍武装, Samurai Busō).
Its name in Japanese either means "Divine Sword King" or "True Sword King".

The transformation sequence begins with Shinken Red writing the kanji and shouting out, "Samurai Gattai!(Samurai Combination).The Shishi or Lion Origami becomes the head and the body, the Saru or Monkey Origami and the Kame or Turtle Origami became the arms, and the Ryuu or Dragon Origami and the Kuma or Bear Origami became the legs and the helmet. The arms and legs join together with the body and the helmet is put on to complete the transformation.
- Prior to learning the proper way of combining by Takeru, Ryuunosuke lead the other four to combine their origami together, ultimately leading to them stacking on top of each other in shape-form in a formation that resembled a stick of oden. It was ultimately useless, but Kotoha liked this formation as well.
- Combining with the Samurai Gattai DaiTenku, ShinkenOh becomes Super Samurai Gattai Tenkuu ShinkenOh
- Combining with the Ika Origami, ShinkenOh becomes Ika ShinkenOh
- Combining with the Kyoryu Origami, ShinkenOh becomes Kyoryu ShinkenOh.
- Combining with the Ebi Origami, ShinkenOh becomes Shin Samurai Gattai DaiKaiShinkenOh.
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including ShinkenOh which possibly manifested from a toy version like DaiDenzin and the Variblune, appeared to back them up. When the Black Cross Colossus summoned several giant villains to oppose them, ShinkenOh fought alongside Senpuujin and Muteki Shogun to destroy Buredoran of Chimatsuri. After all the giant villains were destroyed, all 35 mecha weakened Black Cross Colossus with a combined attack before GokaiOh combined with the Variblune to become Goren GokaiOh which destroyed the Black Cross Colossus with the Gokai Hurricane: Cassiopeia finisher. With the battle won, the 33 past Super Sentai mecha vanished.
