Gamamaru

The is the oldest and most respected Toad of them all, that lives at Mount Myouboku. Since his only appearance so far has been in a flashback, it is unknown if he is still alive.

Personality
As guessed his old age has made him senile, and he then 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.

Appearance
He has an old man sage like appearance and seems to constantly smile. During his short appearance he is constantly having his eyes closed, which could mean that age has taken its toll on his eyesight and made him blind.

Infiltration of Amagekure
So far the Toad Sage only made one appearance, being in a flashback of Jiraiya's, who remembered being told about about a prophecy the Toad Sage had about him. However, when he arrives the Toad Sage only laughs and stares, being unable to remember who Jiraiya is, until Fukasaku tells him, and he is being scolded by Shima for being senile. He then forgets why Jiraiya is there until Fukasaku tells Jiraiya that he has had a vision concerning him.
