Golding introduces Ralph as a "fair-haired" boy. On about page 7 we read that Ralph, "was old enough, 12 years and a few months, to have lost the prominent tummy of childhood; and not yet old enough for adolescence to have made him awkward. You could see now that he might make a boxer, as far as width and heaviness of shoulders went, but there was a mildness about his mouth and eyes that proclaimed no devil." "He has a "directness" in his manner that the narrator calls a sign of "genuine leadership." Ralph is described by E.M. Forester as "sunny and decent, sensible and considerate."
Ralph's dad is an officer in the Navy and this probably explains Ralph's sense of honor, discipline and the desire to make sure everyone is taken care of properly.
