Nobisaku Nobi is Nobita's ancestor, best known for appearing in the original manga and across multiple anime adaptations—the 1973, 1979, and 2005 versions all featured him. Like the rest of his line, he's not exactly gifted; he struggles at hunting and lacks real talent, which hasn't stopped him from dreaming of becoming a samurai like his idol Omaru.
Physically, he's a dead ringer for Nobita. His typical look includes glasses, a jacket worn over a t-shirt, and a farmer's hat. Though there's some variation across adaptations—in the 1979 and 2005 remakes, he trades the farmer's hat and glasses for a ponytail instead.
