In Harry Potter, Severus Snape [spoiler alert] is posed from the beginning as an antagonist. His name even sounds like a snake, and he’s built up to be a menacing force of evil. His unyielding black attire, his low, eerie tone, his marauding lurks around corners – all of these aspects paint him as a sure-fire villain. Yet, it turns out, he is the opposite, in the protagonist’s corner the entire time.
