Hanbunkotchi (はんぶんこっち) is a teen stage character that debuted on the Tamagotchi On.
Hanbunkotchi's name comes from the Japanese word "hanbunko" (はんぶんこ), which can mean "half", or splitting something evenly between two people, in this case referencing Hanbunkotchi's split colors. It's also possible the -ko particle may allude to "the child of (both halves)". This may also be a nod to the established m!x function.
Hanbunkotchi has a large head and small body, with a tuft on hair on its forehead. It has large eyes, pink cheeks, and two horns. Hanbunkotchi's body is split in two colors; the left side is always slate-blue; the right side and face are blue when a boy, and pink when a girl. In second generation and on, the color on the right side can differ. In its character art, the right side is yellow.
