Background
Log was created as a synthetic human by Orochimaru, being cultivated from an embryo and given the name, after and the sixth sign of the Chinese zodiac calendar,. However, he rebelled against Orochimaru, escaped and, now calling himself Log, started down the path of destroying the original embryo from which he originated, deeming Orochimaru's experiments to create life unethical. This background story was soon revealed to be a ruse set up by Log and Orochimaru in order to force the young Mitsuki to make a decision: either join him in destroying Orochimaru and eventually themselves, remain with Orochimaru and follow his orders, or choose his own path in life.

Personality
He seems to be a rather calm individual. He also enjoys smoking in the manga.

Appearance
Log is a tall individual with dull-blue, shoulder-length hair, and golden eyes. Overall, he bears an exact resemblance to his clone sibling Mitsuki with the exception of a scar across his right cheek. When first seen, he wore a dark-coloured haori, which concealed his entire appearance. When confronting Orochimaru and Mitsuki, he wore what appeared to be a modernised form of a shinobi battle armour complete with large arm-guards, outer thigh-guards and a hybrid breastplate. He also wore a kabuki mask, which had slits for eye-holes, a protuberant nose and a frowning mouth. He takes to using an ornate snake-themed lighter, and carries a sword strapped vertically to his back. In the anime, Log wears a long hooded dark grey cloak.

Abilities
Log appears to be quite skilled as he was able to temporarily fend off and counter his father's — who himself is a renowned shinobi — attacks for a short while. He also makes use of a sword in combat, showing considerable speed and likewise skill in kenjutsu against his father. With his Armour-Eater technique, he is able to manipulate his armour into various shapes to aid him in battle, such as encasing and restraining his opponent.

Mitsuki's Disappearance Arc
In the anime, when Mitsuki apparently betrayed Konohagakure to leave with two attackers, word reached Orochimaru. He then met with Log, discussing the continued development of Mitsuki. They began to wonder what was driving Mitsuki now and if their hopes of him becoming a new light to the world would succeed.

Later, it was revealed that Mitsuki was still loyal to Konoha as he helped in stopping the attack of the Fabrications, which Log found a dull ending. Also, following the passing of Ōnoki, an investigation was done on his work about the Fabrications. However, Log soon reported that all evidence was mysteriously removed, leading him and Orochimaru to wonder who could have helped the Tsuchikage in creating such advanced artificial humans besides Orochimaru himself.
