Gamamaru

The is the oldest and most respected toad of them all, that lives at Mount Myōboku. Despite being so old, he is still alive to this day.

Personality
Being several thousand years old, he is the oldest and most respected among the toads. He constantly smiles and tends to have his eyes closed. He is senile, and tends to forget things quite quickly. However, when reminded, he is still able to remember things and can easily tell things very precisely. He also acts like a sage and is quick to stop Shima and Fukasaku from bickering. It would seem that unlike most other toads, he actually has respect for Jiraiya, and has even urged Shima and Fukasaku to cooperate with him.

Infiltration of Amegekure
During Jiraiya's fight with Pain, he has a flashback to his encounter with the Great Toad Sage. Famed for his highly accurate prophecies, the Toad Sage makes one concerning Jiraiya: that he will become a talented ninja and a pervert without equal; that he will travel the world and write a book; and that he will have a student with the power to save or destroy the world and that Jiraiya's actions will determine which path the student takes. Jiraiya initially assumes Pain to be the student of the prophecy, but before he is killed he realizes that it was Naruto.

Invasion of Pain Arc:
After trusting in Naruto, Nagato revives all those who were killed. There is a short frame that shows Gamabunta in bandages talking to the Great Toad Sage. The Sage is looking at a crystal ball and tells Gamabunta that the battle is over. Though he mentions he didn't expect that it was two of Jiraiya's pupils who were the children of prophecy and would bring about the revolution of the ninja world.

Quotes

 * (To Fukasaku and Shima) "No fighting, children. A husband and wife have to be nice to each other."
 * (To Gamanunta) "It's over... as it was foretold... but I never thought Jiraiya's two pupils together would be the children of prophecy, the ones to lead a revolution in the ninja world. Maybe... this was all meant to be from the time Jiraiya decided not to give up... that book really was the key to changing the world."
