Muggles' Guide to Harry Potter/Characters/Bole

Bole (no first name given) is mentioned as being one of the Beaters in the Slytherin Quidditch team.

Bole is one of two Beaters who attempts to injure Harry Potter in the Slytherin / Gryffindor final. (The other is Derrick.) He is unsuccessful, being out-maneuvered by Harry.

Angelina Johnson mentions Bole (and Derrick, too) in passing, saying that she always was surprised that Bole and Derrick could make it down to the Quidditch pitch without needing signs.
