Kintoleski is a major antagonist from the anime series Futari wa Pretty Cure Splash Star, serving as the final of the five primary generals sent by the forces of Dark Fall. His name is a portmanteau of Japanese words relating to gold and muscle training, reflecting his golden skin and his obsession with physical conditioning. He is the guardian of the Fountain of Gold, aligning him with the element of gold.

Kintoleski possesses a distinctive and formidable appearance, characterized by his tall, muscular, golden-hued physique, a small mustache, and orange hair. Unlike many other villains, his primary motivation is not to serve Dark Fall's ultimate goal of locating the Fountain of the Sun, but to find and defeat a worthy opponent in a fair and decisive battle. He is described as the strongest warrior of Dark Fall, and his power far exceeds that of his fellow generals. His personality is defined by a strict code of honor; he believes a fight should be a fair duel between two strong parties and shows little interest in underhanded tactics or conquest for its own sake.

Kintoleski first appears casually in the human world, frequenting the bakery run by the family of the main character, Saki Hyuuga. His introduction is low-key; he buys bread without causing trouble and even offers Saki advice on how to improve her artistic skills, pointing out the importance of understanding skeletal structure. This behavior perplexes the heroines, as it becomes clear his true goal is to train Saki and her partner, Mai Mishou, the Pretty Cures. He deliberately pushes them to become stronger, believing that only by fighting them at their full potential can he achieve a satisfying victory. His methods involve challenging them directly, pushing them to their limits in combat, and even creating situations that force them to fight for the safety of others.

His role in the story evolves from a straightforward, if unusual, antagonist to a complex figure whose personal honor code ultimately outweighs his loyalty to his master, Akudaikan. When ordered to stop training the Cures and eliminate them, he instead sends them a formal challenge letter, promising to give them a vital item called the Miracle Drop if they can defeat him. In their final battle, Kintoleski unleashes his full power, transforming his body into an even larger, reddish form with greatly increased strength. He withstands the Cures' most powerful attack, the Spiral Star Splash, but the effort expends all his energy, causing his body to disintegrate. In his final moments, he expresses satisfaction with the fight and honorably fulfills his promise, leaving the Miracle Drop behind as he fades away.

Key relationships define his later character arc. He is resurrected alongside other fallen generals and pairs with Moerumba, with whom he fights as a combative teammate. His most significant connection is with his fellow general, Ms. Shitataare. While initially partners in combat, their relationship deepens, and during a Christmas-themed battle, Kintoleski confesses his feelings for her. As they fight the Pretty Cures together, their mutual affection is confirmed, and they both disappear peacefully after choosing to embrace their love over continuing the battle.

Among his notable abilities, Kintoleski possesses superhuman strength, durability, and mastery of hand-to-hand combat, which he constantly trains to improve. He can increase his muscle mass and physical power at will, becoming even more formidable. His most impressive feat is physically blocking and withstanding the Cures' ultimate attack, an accomplishment that highlights his status as the strongest of the Dark Fall forces.
