Originating in the 2018 children's book *Do Your Best, Chibi Godzilla*, this younger Godzilla emerged as a crybaby, contrasting his typically fearsome image. He lived with a human named Satomi and trained to become King of the Monsters, though uncertain what that meant, while encouraging Satomi alongside friends like Chibi Rodan, Chibi Mothra, and Chibi Ghidorah. His background was reimagined in the anime *Chibi Godzilla Raids Again*. Here, he is the son of a colossal Godzilla on Monster Island, motivated to grow large enough to safely hug his father. His design features light green skin, a white muzzle, large circular eyes with black pupils, three claws per foot, and short, white maple leaf-shaped dorsal plates. A notable trait is his involuntary transformation into a second form resembling Kamata-kun when experiencing minor injuries, turning his skin beige or purple and revealing neck gills. The anime shifted his personality from crybaby to eccentric and mischievous, driven by intense destructive urges. He engaged in chaotic acts like setting bear traps for Chibi Mechagodzilla or demolishing model cities, justifying them as inherent monster behavior. Despite this, he maintained friendly rapport with other chibi kaiju, including traditional foes like Chibi Ghidorah and Chibi Mechagodzilla, introducing them to Monster Island's quirks. He occasionally displayed brutal honesty, tactlessly pointing out flaws like dismissing the Shobijin sisters' pretensions. His anime development explored growth and identity. Episodes like "Monster Study Session" featured him teaching nonsensical kaiju lessons, citing things like "sunlight in summer" as Godzilla's toughest foe. "All Chibi Monsters Attack" saw his destructive impulses peak, causing confrontations where his face briefly shifted to a realistic art style. "Chibi Godzilla's Second Form" explored his adaptability to physical changes, including a brief affinity for slugs while transformed. Season 2 introduced Chibi Minilla as his younger sister, while his father remained a distant figure seen only in cameos or chalk drawings. Mythology gags and abilities tied him to broader Godzilla lore. He wielded a blue heat ray (replacing earlier fire breath) at varying temperatures, even using a low-powered version to wake Chibi Mechagodzilla. References included his dislike of "things exploding in his mouth" and flying via heat-ray propulsion. His birthdate, November 3, coincides with the release of the original 1954 Godzilla film.
