Reminds me of
Millicent Bulstrode from
Harry Potter. Here is a character description from mugglenet.com.
"A Slytherin in
Harry's year. She is large and square and has a heavy jaw which she sticks out aggressively. During
Harry's second year, she was a lot bigger than he was. She was partnered with
Hermione at Lockhart's Duelling Club and the two ended up brawling.
Hermione took the opportunity to retrieve what she thought was one of
Millicent's hairs for her Polyjuice Potion, but it turned out to be a cat hair.
Millicent joined Umbridge's Inquisitorial Squad in her fifth year, and took great delight in apprehending
Hermione when she and
Harry broke into Umbridge's office."
