Gamamaru

Gamamaru (ガマ丸), more commonly known as the Great Toad Sage (大ガマ仙人, Ōgama Sennin) is the oldest and most respected toad of all the inhabitants of Mount Myōboku. Because of his age, the other toads affectionately call him Great Honourable Geezer (大じじ様, Ōjiji-sama). He is famed for his highly accurate prophecies.

Appearance
He is one of the largest inhabitants of Mount Myōboku, easily equalling Bunta, Ken, and Hiro in size. He is brown in colour, with a white belly, is very wrinkled and has taken to squinting. He wears a professor's hat with tassels and an orb on top of it. He also wears a necklace with the toad's village symbol for "oil" (油, abura) on it.

The place where he called Jiraiya and Naruto to receive their prophecy is lined with what appears to be giant scrolls and he sits in a shallow pool of water which has the kanji for "sage" (仙人, sennin) inscribed on it.

Personality
At his great age, Gamamaru seems to constantly smile and tends to have his eyes closed or takes to squinting. He is portrayed and described as being senile, and sometimes out of touch with his present situation, so he does tend to forget things easily and quite quickly. However, when reminded, he is still able to remember things and can easily tell things very precisely. As a sage, he is also very wise, and is quick to stop Shima and Fukasaku from bickering and encourages harmony. It would seem that unlike most other toads, he actually has respect for Jiraiya, and has urged both Shima and Fukasaku to cooperate with him.

Abilities
Being the oldest toad sage of Mount Myōboku, he is very wise and has immense knowledge and is greatly respected by his fellow toads. Gamamaru is shown to have immense longevity, having been around since at least before the birth of Hagoromo Ōtsutsuki and Hamura Ōtsutsuki.

Senjutsu
Even when he was still very young, Gamamaru understood natural energy and how to harness with deep knowledge and control. Using it, he could easily lift massive stone structures. His knowledge and skill was so great that he played a pivotal role in aiding Hagoromo and Hamura to stop Kaguya, having taught them personally.
