Michael, an orange American Shorthair tabby cat, anchors all official media as a feline "everyman." He shifts unpredictably across settings and roles, lacking a fixed identity or ongoing storyline. No consistent backstory or personal history defines him. Michael alternates between appearing as a typical housecat with transient human owners—none recurring or connected across chapters—and transforming into an anthropomorphic figure who walks upright, dons clothing, and converses verbally with other animals. This duality extends to his behavior, which toggles between natural feline instincts and fully human-like mannerisms.

His narratives split into two distinct modes. One captures realistic household cat antics, mining humor from innate quirks and instincts. The other plunges into absurdist fantasy, casting Michael in human-society parodies where animals hold jobs, feud in gangs, or pursue romance, blending species traits for comedy.

No character development spans episodes, seasons, OVAs, or manga installments. Michael’s personality, circumstances, and physical fate reset entirely with each story—he may perish in one segment yet reappear unharmed in the next. Owners, companions, and environments shift without explanation, and no narrative threads link his iterations. His role remains strictly comedic and episodic, devoid of evolving traits, relationships, or backstory throughout the franchise.
