Bionic Arm

 is a special mechanical arm designed and created by Shinzui Uchiha with the help of Reikai Corps after witnessing the number of advantages Ryūken's access to high-tech gives him. The arm could be used both to replace a person's lost arm and could be also superficially placed on a person's hand. He gave the prototype to Ryūken so that, he could deliver it to Shinzui's clone.

Abilities
Has some degree of superhuman strength in his bionic arm. The arm has shown to be capable of easily overpowering humans by lifting them up with one hand or by hurling them around. It can also be used to lift extremely heavy objects, crush and break through wood panels and templates, bend metal, and can punch through glass without gaining injury. His arm's reaction time is greater than that of any Olympic athlete who has and will ever compete. The arm houses different sensors which allow him to pass through security such as metal detectors without setting them off. It can also shield other metallic objects from detection such as firearms and knives. He can apparently either control his bionic arm even if it has been removed from his body (possibly by cybernetic implants), or his arm can be programmed to perform certain actions on its own while removed from his body. He can discharge bolts of electrical energy from his arm's palm. He can discharge an EMP rendering electronic devices useless. Much like the Asura path, he can launch his arm using it as a projectile weapon. With a small-scale explosion, caused by chakra collected in the cut end of the wrist, the hand portion gains propulsive power and flies off in a straight line with tremendous force.

Later, Shinzui installed a Gatling Gun in the arm to further enhance it's performance. The powerful automatic machine gun added to his arm fires many bullets simultaneously.
