Gamahiro

is comparable in size to Gamabunta. When summoned during Part I he is not named. It is not until Part II that his name is revealed. He carries two large swords on his back.

Part I
He first appeared in the Konoha Invasion arc when Jiraiya used him to fight Orochimaru's large snakes by using Summoning: Food Cart Destroyer Technique. Jiraiya summons him again in the anime to help Sasame Fuma, Sakura Haruno, and Naruto Uzumaki get out of Orochimaru's hideout.

Invasion of Pain
Gamahiro makes his Part II debut when he, along with Gamaken and Gamabunta, are summoned to assist in Naruto's fight with Pain. They combat the various animals summoned by the Animal path until they are sent flying beyond Konoha's borders by the Deva path. He is currently laying motionless in a lake.

Trivia

 * He has different skin color between the anime, where he has a green and brown theme, and the manga; where he has a bluish theme. This is most likely due to him being colored in the anime before the manga.
 * He appears in Naruto Ultimate Ninja Storm for the PlayStation 3, when Jiraiya uses Summoning: Bring Down The House Jutsu
