Gamabunta (ガマブン太, Gamabunta) is the personal summon of Naruto.
Gamabunta is a very large toad, which towers over trees, dwarfs most large rock formations, and is larger than most buildings. He's so large he's comparable in size to the gargantuan tailed beasts like Shukaku and Kurama, with him being as large as the Fox's entire torso. He is coloured a dull, rusty red, but around his eyes and on his lips and chest are brighter red markings. Over his left eye, he received a scar at some point in the past, but can still see out of it. His eyes are yellow with horizontal black line for pupils. His tongue has a series of stud-like piercings on both the upper and lower side. He often wears a large blue happi vest, and always carries a massive dosu blade at his hip. He also carries a large kiseru pipe which he often smokes.
Gamabunta is a grumpy and highly apathetic toad. He does not like to take orders from anyone, unless the summoner is highly talented and earns his respect. Jiraiya, Naruto and the Fourth Hokage are three of the few people that he has allowed to ride on top of his head without question. While he is quite confident of his abilities as a fighter, he is well aware of his limitations and perceptive of the power of his enemies, shown in his apprehension when confronting Shukaku head-on.
