Gamabunta (ガマブン太) is the boss of the toads that are summoned. He is huge (about 100 meters high) and is summoned for battles with the biggest of enemies. At first, Naruto could only summon him with the Nine-Tailed Demon Fox's chakra. Without it, Naruto could only call upon some of Gamabunta's smallest children. Gamabunta was first seen in the premiere of the series, where he and the Fourth Hokage face off against the demon fox. He is not given a speaking role until he is first summoned by Naruto.
