Gama

is the first toad named in the series, debuting alongside Jiraiya. He was the only summon shown to strike the same pose as Jiraiya. This toad seems to be the keeper of the Toad Summoning contract scroll. Gama has not yet been seen talking, only croaking once or twice and mainly in the anime.

Appearance
Gama is a very large toad, enough for Jiraiya to ride on his back. His orange skin is covered in blue spots, he has bandages wrapped around his chest and left foreleg, and wears a necklace with seven large beads on it, with the kanji for "loyalty" (忠, chū) on the central, largest one. In battle, he is almost always seen wearing samurai armour, composed of a plate cuirass and armguards paired with traditional samurai pauldrons.

Chūnin Exam Arc
Gama is first summoned to tongue-whip Ebisu for annoying Jiraiya at the hot springs. He's summoned again soon afterwards to give the contract scroll for the Gama family to Naruto Uzumaki. There he stayed for a little while, while watching Naruto fail in summoning a real toad.

Search for Tsunade Arc
He was later summoned by Jiraiya, clad in armour, to block Kisame Hoshigaki's attack on Naruto Uzumaki.

Land of Rice Fields Arc
In the anime, he is summoned to save Naruto from Kagerō's Earth Release: Antlion Technique.

Part II
Gama takes part in Jiraiya and Naruto's training between Part I and Part II.
