In the 1960s anime versions, he is a child rather than an adult, in an attempt by the producers to appeal to a younger audience. Though Ishinomori initially disapproved of this, he later temporarily mirrored it in the manga version by having Gilmore alter 007's body to make the child form his standard form.
