Toriko is a Bishokuya with an abnormally large appetite (as a food serving for 500 people could only get him 1/10 full). He is known as one of the "Four Heavenly Kings", and his nickname is "The Glutton". He is an incredibly skilled Bishokuya, having discovered roughly 2% of the approximately 300,000 varieties of known ingredients worldwide, which is around 6000 varieties. He is also the adoptive father figure of a new born Battle Wolf pup named Terry Cloth and is the only human known to have ever tamed a Battle Wolf. He is currently seeking the fabled holy ingredient from Acacia's Full Course Menu, GOD, which is said to be the greatest main dish in the world and hopes to add it to his own Full Course Menu, despite that this ingredient is also being sought after by the brutal criminal organization, the Bishokukai and many other powerful figures. He is currently in a Combo with Komatsu.

The father of Baki and Jack Hanma. He is the strongest creature in the world, and is known to have mastered all styles of unarmed combat. His repertoire apparently includes all of the well-known fighting styles (such as karate, boxing, taekwondo, judo, jujutsu, wrestling, street-fighting, and so on) as well as some more esoteric ones (such as the udonde or uzunde style, an actual system used in the Motobu style of karate). He has been fighting on the battlefields, using only his bare hands, since the age of sixteen, when he fought against both American and Vietcong in the Vietnam War. Since then, it appears that he has obtained respect from the American forces, and has begun fighting as a kind of mercenary for them. It is said that when he stopped fighting for survival but for pleasure the image of the demon's face appeared on his back.
