Gari

is an Iwagakure ninja who was resurrected by Kabuto Yakushi to fight in the Fourth Great Shinobi War.

Appearance
He has spiky dark hair and angular cheek bones, characterized by a prominent line running down either side of his face. He wears a standard Iwagakure flak jacket with a large pouch strapped across the front of it, and single sleeve shirt underneath, leaving the entirety of his right arm exposed except for the presence of his forehead protector, wrapped around the upper portion of his arm.

Abilities
He was a well noted shinobi during his lifetime since he was resurrected by Kabuto Yakushi. He has demonstrated great knowledge, being able to recognize a rare and forbidden jutsu. He seems to have great physical prowess and to specialize in offensive taijutsu, which he uses in conjunction with his kekkei genkai.

Nature Transformation
Gari is able to use Explosion Release, a kekkei genkai that allows him to combine two unknown chakra natures to utilize explosive chakra, as seen when he used Explosion Release: Landmine Punch to obliterate an Allied Shinobi Jōnin simply by punching him.

Shinobi World War Arc
Shortly after his resurrection and during the course of relocating to an unknown destination, he over hears Haku and Zabuza Momochi conversing with each other over the state of their present condition, where he reveals to the pair the exact nature of the forbidden technique used to summon them and the most probable reason for an individual to do so.

When the Surprise Attack Division attacks the group he is in, Haku protects Zabuza from Sai's ink birds, which carried explosive tags, but Gari has his arm destroyed. While it regenerates, Haku and Zabuza note that the technique which brought them back also makes it impossible for them to be killed.

When he and Pakura discover that their opposition are, as they put it "children", they are hesitant to attack, but Gari assures her that with immortal bodies its alright for them to simply trade blows. Zaji of the Shinobi Forces's Surprise Attack Division reveals that every member of this team has a kekkei genkai, to which Zabuza remarks himself as an exception.

Trivia

 * Gari resembles a shinobi who was abducted by Hiruko for use with his Chimera Technique during the events of Naruto Shippūden 3: Inheritors of the Will of Fire. Hiruko integrated part of the shinobi's remains with his own body to steal one of four Kekkei Genkai abilities: either Storm Release, Dark Release, Steel Release, or Swift Release.
 * However, Gari possesses the Explosion Release, which Hiruko did not possess.
