Toriko, a Gourmet Hunter famed for his superhuman capabilities, relentlessly pursues completion of his ultimate Full Course Menu. Born on May 25 in the Gourmet Age, he shares a twin bond with Starjun; both originated from the same womb, born infused with Gourmet Cells. The Blue Appetite Demon dwelling within him manifests in his distinctive blue hair. Discovered as a starving orphan in an impoverished nation during an IGO food distribution by executives Ichiryu and Mansam, Toriko's inherent generosity surfaced when he tried to share offered bread with his village despite his own starvation. Ichiryu adopted him alongside Coco, Sunny, Zebra, and Rin. Trained by Ichiryu, these five ascended to elite warrior status, with Toriko and three others ultimately designated the Four Heavenly Kings.

Physically imposing, Toriko stands 220 cm tall and weighs 230 kg, boasting a heavily muscular build. Three prominent scars trace from his left ear to below his eye, inherited from his primordial White Appetite Demon. He typically wears an orange jumpsuit paired with a dark blue sleeveless vest and matching boots, adapting attire for environments like desert robes in the Sand Garden. Intense rage transforms his appearance: canine teeth elongate, veins bulge, and muscles expand, giving him a feral aspect.

Multiple Appetite Demons inhabit Toriko, manifestations of his Gourmet Cells and voracious appetite. The Red Demon (Ogre), resembling a Hannya-like entity, projects as his Intimidation aura. The Blue Demon, linked to his hair color, exhibits a more sinister persona. A third entity, the White Demon—pale with black hair and wings—is the original power within him, feared even by his father Acacia for its latent potential. These demons grant Toriko immense abilities, evolving as he consumes rare ingredients like GOD and CENTER. His combat techniques include Fork (finger stabs) and Knife (hand chops), later enhanced with Leg variants. Signature moves involve Spiked Punch (rapid strikes) and Cannon Fork (converging energy projectiles). His Gourmet Cells enable environmental adaptation, regeneration (reattaching severed limbs), and energy absorption from food.

Personality-wise, Toriko embodies ethical hedonism: passionately pursuing culinary perfection while deeply respecting food sources. He refuses to kill animals he won't consume, employing non-lethal Knocking or Intimidation instead. Disrespect for life or harm to Komatsu ignites his fury. Initially driven by personal culinary ambitions, he evolves into a selfless protector, notably saving the Human World from famine by sharing Gourmet World ingredients. His relationship with Komatsu deepens from professional convenience to profound loyalty; Komatsu's near-death experiences become a powerful trigger for his rage. Toriko marries Rin after she supports him during a depressive episode following Ichiryu's death and Komatsu's abduction. His rivalry with Starjun shifts from hostility to alliance against threats like Neo.

Key arcs chart his growth. Early missions—capturing the Galala Gator or Rainbow Fruit—exemplify his hunting ethics and partnership with Komatsu. The Century Soup quest demonstrates his resilience in extreme environments. Gourmet World expeditions push his limits, awakening his Blue Demon against Heracles. Consuming Acacia's Full Course ingredients (GOD, CENTER, etc.) unlocks his White Demon, enabling victory over Acacia/Neo. Post-series, Toriko explores space seeking new ingredients aboard a biomechanical vessel.
