Robonyan Type-F, a robotic feline Yo-kai upgrade, sports a sleek two-tone white and blue chassis with cyan photoreceptors, a gray muzzle, inner ears, paws, and chest plate. A dark gray collar bearing a flame insignia accents its neck, while a glowing yellow orb rests on its torso. Sky-blue flames erupt from its tail, complementing the jetpack affixed to its back. This mechanical evolution of Robonyan balances pragmatic respect for its predecessor’s capabilities with pride in its own superior enhancements. Its combat arsenal includes generating instant Chocobar production facilities and firing missiles potent enough to annihilate landmasses. During the third Yo-kai Watch film, a fusion chemical engineered by Hailey Anne—infused with essence from Usapyon, Jibanyan, Komasan, and Hovernyan—triggers Robonyan Type-F’s metamorphosis into Ultimate Robonyan. The upgraded form boasts a streamlined, towering frame with elongated, booster-equipped legs, a third ocular sensor on its forehead, and narrowed visual receptors. Its attacks manifest as Yo-kai-shaped projectiles, pivotal in defeating Whaleman. Ultimate Robonyan’s Soultimate Move unleashes vertical missile barrages, while its Skill negates enemy inspiritments and battlefield hazards. The character’s timeline intertwines past and future through a recursive causality loop: encountering its own upgraded form motivates Robonyan to engineer Robonyan Type-F, creating an ontological paradox. Notably, it becomes the first Yo-kai in the anime continuity to suffer irreversible deactivation, raising narrative consequences for the series’ stakes. Game appearances span *Yo-kai Watch 2*, *3*, and *Blasters*, where players obtain it via Crank-a-kai items or quests like "Those Seeking the Ultimate Upgrade," enabling its evolution. It anchors the Clockwork Yo-kai Circle, enhancing team strategies with synergized abilities. Quotes like "ROBONYAN F IS PERFECTLY TUNED TO THIS ADVENTURE" and remarks about users’ "glorious good luck" when summoned reflect its technical precision and self-assuredness. Manga arcs, including *The Attack of the New and Improved Robonyan!*, depict it rebuilding itself from critical damage before coercively recruiting Stataking as an energy source, clashing with Nate’s team over its morally ambiguous recruitment tactics. This storyline probes conflicts between autonomous machinery’s logic and organic free will.
