Description
Hajime, born significantly past his due date, experienced repeated delays as loud noises or chaos startled him back into the womb. A family naming discussion followed his eventual birth. His brother suggested "Pochi" or "Tama," his father proposed "Torao," "Kabao," or "Kiritaro," but his mother chose "Hajime," meaning "beginning" or "first," reflecting her desire for the best name.
Hajime is a genuine child prodigy, exhibiting extraordinary intellect from infancy. He understood language almost immediately after birth, could coherently explain complex subjects like the Pythagorean theorem and Kepler's laws while still a baby, and rapidly acquired speech and cognitive skills, surpassing his family. His father's unconventional, absurd reasoning presented a contrasting form of intelligence. Hajime's trajectory was likely influenced by inheritance, as his father was also an infant genius before an accident altered his abilities.
Physically, Hajime is a small child, ranging from infant to toddler. He has short chestnut brown hair with a single prominent spiral ahoge. His eyes are shiny and black, resembling his mother's, and he bears distinctive rosy spiral cheek markings like his older brother. He typically wears a simple shirt with a single button, sometimes with pants and shoes, but is also frequently shown without pants.
Personality-wise, Hajime is generally gentle and easy-going but often experiences frustration and confusion due to his father's nonsensical behavior. He dislikes being underestimated or perceived as quiet or unintelligent due to his age and size, voicing his displeasure when this occurs. He possesses deep love for his family, motivating him to rescue them from difficult situations, though his genius intellect sometimes makes him a kidnapping target. His skills include inventing practical devices, repairing machinery, conversing and teaching in English, and occasionally tutoring neighbors, willingly sharing his knowledge.
Hajime's depiction evolved across adaptations. The 1971 anime portrayed him predominantly as an infant, often held by his mother and unable to walk, typically in a yellow onesie with a bib. The 1975 series ("Ganso Tensai Bakabon") showed him walking; his clothing shifted to a yellow shirt with green overalls. The 1990 "Heisei Tensai Bakabon" retained his genius toddler characterization, with notably more polite speech; his wardrobe was updated to a yellow shirt with green shorts. The 1999-2000 series "Rerere no Tensai Bakabon" further advanced his intellect, portraying him as one of the world's smartest individuals, proficient with a personal computer; his attire reverted to a signature single-button shirt, often without pants, aligning closer with the classic manga.
His family relationships are defined by these dynamics: his father's unpredictable antics frequently baffle him, his mother provides stability and sensibility, and his older brother engages with him more playfully, sharing their father's mischief. Hajime's presence initially served as a smarter foil to his brother, though narrative focus shifted increasingly toward the father. Nevertheless, Hajime occasionally steps in as a problem-solver, using his intellect to navigate or resolve familial chaos.
Beyond the main series, Hajime appears in other Fujio Akatsuka "Star System" media, including educational spin-offs like "Nyarome's Fun Mathematics Classroom," "Nyarome's Fun Cosmology Classroom," and "Nyarome's Fun Biology Classroom," plus crossovers like "Oh! Great Jailbreak," and narrative works "BC Adam" and "Kensaku the Architect." Live-action adaptations portrayed him at a later toddler stage, emphasizing abilities like speaking perfect English and independently operating advanced technology such as a 3D printer, while maintaining clothing styles similar to the 1975 anime.
