In literature, who was the best known pupil of Greyfriars School?

William George Bunter (known as Billy Bunter) is a fictional schoolboy created by Charles Hamilton using the pen name Frank Richards. He features in stories set at Greyfriars School, originally published in the boys' weekly story paper The Magnet from 1908 to 1940. Subsequently, Bunter has appeared in novels, on television, in stage plays, and in comic strips.

He is in the Lower Fourth form of Greyfriars School, known as the Remove, whose members are 14–15 years of age. Originally a minor character, his role was expanded over the years with his antics being heavily used in the stories to provide comic relief and to drive forward the plots.

Bunter's defining characteristic is his greediness and dramatically overweight appearance. His character is, in many respects, a highly obnoxious anti-hero. As well as his gluttony, he is also obtuse, lazy, racist, inquisitive, deceitful, slothful, self-important and conceited. These defects, however, are not recognized by Bunter.
