Kintaros (キンタロス Kintarosu?) is the third Imagin that gives Ryotaro his power, which allows for the Ax Form transformation. He is vaguely modeled after a bear and has a Sumo wrestler-like personality. He also has a habit of deep sleeping (akin to hibernation) until the mere mentioning of any word that sounds remotely similar to the Japanese word for "to cry" (泣く naku?) often provokes Kintaros out of his slumber to possess Ryotaro in an instant. He speaks in a the dialect of Kansai-ben, saying, "You wept over my strength. Wipe off your tears." (俺の強さに、お前が泣いた。涙はこれで拭いとけ Ore no tsuyosa ni, omae ga naita. Namida wa kore de fuitoke?)[1], whenever he possesses Ryotaro, taking out a handkerchief for whoever wants to wipe their tears off with. His natural weapon as an Imagin is a giant battleaxe named the Kintaros Ax (キンタロスアックス Kintarosu Akkusu?). He has a habit of popping his neck every time he begins and ends a battle, as well having "You wept" (泣けるで Nakeru de?) as a battlecry. Kintaros is a strong Imagin who constantly seeks opponents stronger than him. Unfortunately, he is sometimes unable to control his own strength resulting in accidentally destroying things, which he attempts to fix afterwards. He is also very selfless. At first, he is dependent on a retired karateka named Masaru Honjō, who gave him his "bearish" look, as he attempted to master karate so Masaru could achieve the "ultimate karate". Kintaros wants to teach Masaru the ultimate karate, in order to let him settle things with Kikuchi instead of disturbing the timestream. Seeing the good side of Kintaros when he protects Masaru from the Rhino Imagin and being mortally wounded in doing so, Ryotaro allows Kintaros to enter a contract with him, saving the Imagin's life.
He usually refers to Momotaros as "Peach" (桃の字 Momonoji?, mispronouncing his name as "Momonga" (モモンガ Momonga?, Japanese Dwarf Flying Squirrel), "Momohiki" (モモヒキ Momohiki?, Long Underpants)) and refers to Urataros as "Turtle" (亀の字 Kamenoji?). Kintaros' physical form, based on that of a strong golden bear, are aspects of the traditional myth of Kintarō (金太郎?) the Golden Boy, said to be strong enough to wrestle bears and demons.
