Severus Snape

I can teach you how to bewitch the mind and ensnare the senses. I can tell you how to bottle fame, brew glory, and even put a stopper in death—if you aren't as big a pack of dunderheads as I usually have to teach.

The character of the wizard Severus Snape, also known as the Half-Blood Prince, appears in the Harry Potter book and film series. The perpetually scowling Slytherin professor from Hogwarts School of Witchcraft and Wizardry reliably made Potions and Occlumency lessons a misery for Harry Potter. Severus is not only a Potions Master but also a talented and feared wizard with a deep knowledge of the Dark Arts. After all, balancing the duties of a Death Eater with membership in the Order of the Phoenix is no simple task.
