Code

is an Inner from the organisation Kara.

Personality
Code appears to have a mocking and arrogant demeanour, as he grinned when Jigen put Victor in place and mocked Delta for being weaker than him, being confident that either he or Boro could handle Naruto and thus assured one of them would be sent in to deal with the Hokage and retrieve Kawaki.

Appearance
Code is a young man with a medium build and short, messy hair. A craniofacial prosthetic resembling a studded belt covers part of his scalp and face, stretches from above his right eye to under his left eye, partially hiding facial scars. He has the Roman numeral Ⅵ under his right eye and wears triangle earrings, an inverse of those worn by Delta.

Abilities
Being an Inner of Kara, Code is regarded as completely monstrous in terms of power, and has had his body modified with Scientific Ninja Tools by Amado. Describing himself as stronger than Delta, Code even seemed confident he or Boro would be sent in next after Delta was decisively defeated to retrieve Kawaki from Naruto. Kara also held his might in high enough regard that he was sent to guard the valuable Ten-Tails and when he was about to attack Jigen, Koji Kashin, another powerful Inner, showed caution at the possibility of either him or Boro being there to defend Jigen, suggesting his strength may be a match for Koji's. He is capable of Space–Time Ninjutsu, able to enter and leave the Ten-Tails' dimension at will.

New Era
At some point after the Chūnin Exams, Code looked into Naruto Uzumaki to determine whether or not Momoshiki Ōtsutsuki had marked him with his Kāma before being killed, but found no evidence of the mark on his body.

Kara Actuation Arc
In the anime, Code was present when Jigen called a meeting with the Inners, informing them of the destruction of one their facilities in Amegakure set by an Outer.

Ao Arc
Code attended a meeting held by Jigen to discuss the urgent situation relating to the missing "vessel". As Jigen dispelled the genjutsu, he voiced that they must recover the vessel at all costs.

Kawaki Arc
After Delta was defeated by Naruto Uzumaki, Code was present when she debriefed Jigen on her failed mission. He told her that she was too weak to face Naruto, and thus the task would fall to either himself or Boro. He was also surprised to learn that Momoshiki had left behind a Kāma after all, wondering if it was placed on Sasuke Uchiha before Delta revealed that Boruto Uzumaki was the one who received the mark. Later, while Jigen was recovering after the battle against Naruto and Sasuke, Code was with the Ten-Tails. He reported to Jigen, who informed him that there has been no contact from Boro in a while, and was instructed to keep a close watch, as Konohagakure had learned of the location.

Trivia
