Hermione Granger
In the first book Hermione had the personality of a snob, and a geek, and she is not very friendly but with the time she improves that. Hermione was teased as Mudblood (Witch/ Wizard born with no Magical parents, also known as an offensive insult on Muggle Born Witch/ Wizard) by many Slytherins, especially Draco Malfoy. Her name refers to The Winter's Tale, by William Shakespeare, and was the daughter of Helen of Troy from Ancient Greek Mythology.
