Shuriken Gattai Shurikenjin (手裏剣合体シュリケンジン) is the main Giant Robo of the Ninningers. It is made up of five Otomo Nin (オトモ忍).

Overview
Shurikenjin is formed when AkaNinger spins his Otomo Nin Shuriken in the Ninja Ichibantou and the Shuriken Fusion (シュリケン合体) is announced. During so, Shinobimaru assists the other Otomo Nin in their transformation into a giant exosuit/throne, where it sits in place and a giant Otomo Nin Shuriken: Red is then placed on its head and a mask covers its face, forming Shurikenjin.

Shurikenjin's main arsenal are the the Drago Sword (ドラゴソード) and the Drago Shield (ドラゴシールド).

Shurikenjin's finisher attack is Shurikenjin: Splendid Slash (シュリケンジン・アッパレ斬り), where the Drago Sword charges with an energy and slashes the opponent.

Shinobimaru (シノビマル) is AkaNinger's personal Otomo Nin, taking the appearance of a humanoid mecha. When piloting Shinobimaru, AkaNinger positioned himself on the left shoulder. This Otomo Nin's special ability is to create hidden traps or passages, making it a giant ninja. It is also fleet-footed, allowing it to run at great speeds, as well as run up building sides and being agile enough to leap-frog over enemies. For offense, it mainly uses speed to get in close for melee attacks.

Shinobimaru forms the main part of the Shurikenjin formation, becoming the main controlling unit. Shinobimaru can temporarily separate from the formation to outsmart the opponent.

When other mechas take over its position of Shurikenjin's controller and chest piece, Shinobimaru can become either the resulting formation's left hand or right hand.

Dragomaru (ドラゴマル) is AoNinger's European dragon-themed Otomo Nin. When piloting Dragomaru, AoNinger usually positioned himself at Dragomaru's upper torso. By itself, it can fly with its wings and emit hot flames from its mouth.

During the main Shurikenjin formation, Dragomaru becomes the left hand of Shurikenjin, with its tail being used as the Drago Sword and his wings combining into the Drago Shield. During the Shurikenjin Drago formation, Dragomaru become the chest piece, with the tail and wings being placed on the formation's back to give the combination its flight capabilities.

In its first appearance, Dragomaru was shown riding a giant blue kite before flying on its own. This is a nod to certain ninjas that use kites as aerial transportation.

Dumpmaru
"Dare ja, dare ja?! Da~re, dare ja?! Dare ja, dare ja?! Da~re, dare ja?! Dumpmaru!"

- Summoning announcment

Dumpmaru (ダンプマル) is KiNinger's personal dump truck-themed Otomo Nin. KiNinger usually positioned himself at the front of the truck somewhere above where the cabin is. By itself, it can toss explosive  at its opponent via two small sub-arms. It can also store large rocks on its back to throw it onto the opponent.

When forming Shurikenjin or Shurikenjin Drago, Dumpmaru becomes the torso and right arm. When an auxiliary mecha take Shinobimaru's place in other Shurikenjin formations, the Dumpmaru arm will be swapped with Shinobimaru, becoming the left arm.

Wanmaru (ワンマル) is ShiroNinger's ninken (忍犬)-themed Otomo Nin. ShiroNinger positioned herself at the dog's back. By itself, it can used the Kunai that hold onto its mouth to attack the opponent. Wanmaru usually rides on Byunmaru's back portion, as it also hides there.

During the Shurikenjin formation, Wanmaru docks itself to the left leg that Byunmaru formed.

Wanmaru's name contains "wan" (ワン), the Japanese onomatopoeia of a dog's bark.

As Shurikenjin, Byunmaru forms the legs.

- Shurikenjin Drago combination

Shurikenjin Drago (シュリケンジンドラゴ) is the alternate form of Shurikenjin formed when Dragomaru switches place with Shinobimaru.

Much like Shurikenjin, once the Shuriken Fusion (シュリケン合体) is announced, this time by AoNinger spinning his Otomo Nin Shuriken in the Ninja Ichibantou, Shinobimaru switches places with Dragomaru, where Shinobimaru becomes the left hand and Dragomaru sits in the exosuit and a giant Otomin Nin Shuriken: Blue is placed on its head, creating a larger dragon head and forming Shurikenjin Drago.

Shurikenjin Drago can participate itself in an aerial combat against aerial-themed opponents and can release fire from its mouth. It can also use its razor-sharp wings to slice at an opponent, as well as using its tail to attack.

Shurikenjin Drago's finisher attack is Shurikenjin: Drago Burst (シュリケンジン・ドラゴバースト), where it fires a stream of energy, aiming it at the ground then lifts up to carve a path of destruction to the unfortunate Youkai standing in the attack's war path.

Shurikenjin Paon
"Paon, Paoooooon! Wasshoi! Paon, Paooooooon! Wasshoi! Shurikenjin... Paooooon! (Indian musical fanfare)"

- Shurikenjin Paon combination

Shurikenjin Paon (シュリケンジンパオーン) is the alternate form of Shurikenjin formed when Paonmaru takes over Shinobimaru's place with the Otomo Nin placed into the formation's right hand, while the giant Otomo Nin Shuriken: Paon is placed on the head in place of the Shinobimaru one. This is performed when AkaNinger spins his Otomo Nin Shuriken: Paon in the Ninja Ichibantou and the "Shuriken Paon Combination" (シュリケンパオーン合体) is announced. This form specializes in power-type attacks.

Shurikenjin Paon is armed with twin Paon Axes (パオンアックス) formed by Paonmaru's rear feet (machine cannons in its Humanoid Form) to hack at the giant Youkai, while the Paon Jet (パオンジェッ) used in the Normal Otomo Nin form can also be used here to injure it before the finisher.

Shurikenjin Paon's finisher is Shurikenjin: Paon Boomerang (シュリケンジン・パオーンブーメラン), where the twin Paon Axes are thrown at the giant Youkai creating a X-slash before returning to the arms of Shurikenjin Paon, just like a pair of returned boomerangs.

Shurikenjin UFO (シュリケンジンUFO) is an alternate form of Shurikenjin formed when UFOmaru takes over Shinobimaru's place with the Otomo Nin placed into the formation's right hand, while the giant Otomo Nin Shuriken: UFO is placed on the head in place of the Shinobimaru one. This is performed when AkaNinger spins his Otomo Nin Shuriken: UFO in the Ninja Ichibantou and the "Shuriken UFO Combination" (シュリケンUFO合体) is announced.

This form gives Shurikenjin a flight boost and gives Shurikenjin the ability to chase down and battle enlarged Youkai that are capable of extra-atmospheric or even zero-gravity combat, patching up Shurikenjin Drago's limitation of flying only within the Earth's Atmosphere.

Shurikenjin UFO is armed with the UFOmaru Launcher (UFOマルランチャー), which typically is used as a short trident lance during normal combat to injure the enlarged Youkai before launching the finisher.

Shurikenjin UFO's finisher is Shurikenjin: UFO Big Bang (シュリケンジン・UFOビッグバン), where the robot charges up the UFOmaru Launcher to fire three guided Nin Shurikens which strikes the target in all directions to defeat the Giant Youkai, forming the Ninningers' insignia in the process.
