Garaga

is an inhabitant of the Ryūchi Cave, and the personal summon of Boruto Uzumaki.

Background
At some point, Garaga lost his right eye in a battle. Since then, he became so violent that even the other snakes avoid him, prompting the White Snake Sage to consider him a nuisance.

Personality
Garaga is a very dangerous snake, prone to major violent outbursts. He outright declares his hatred of humans and any who gets in his way, showing a very short-tempered and irritable nature.

Appearance
Garaga is a massive snake. He is coloured red, and has black rings running down intervals on his body. He has a pronounced forehead with a single left eye while the right is scarred over. He also developed a reverse scale, a jewel-like scale under his jaw which is a rare trait only developed by the most aggressive of snakes.

Abilities
Due to his size and strength, Garaga can coil himself around his target, immobilising them. He also spits a venom that is able to petrify the victim moments after contact.

Mitsuki Arc
Garaga attacked Boruto, Sarada, Shikadai, Inojin, and Chōchō when the Konoha genin were requested by the White Snake Sage to take his reverse scale, but was interrupted by Aoda. After his battle against Aoda, he swore to kill any human that comes near him no matter who they are. Ultimately, the genin and Aoda attempted to subdue Garaga long enough to obtain his Reverse Scale, only for Garaga to petrify Chōchō to escape. While the group created another strategy, Boruto was able to enter Garaga's memories and find out why he is violent. It was later revealed at the end he decided not to take Garaga's revere scale and instead enter into a summoning contract with him instead making a bet with him that if he is able to get Mitsuki back, he will accept him as an equal and if he isn't able, Garaga can devour him. Garaga later accepts the bet.
