Luna Lovegood
Many people in the Harry Potter series think she is a strange girl. This has led to her having the nickname "Loony Lovegood", but she does not change herself. She is the daughter of Xenophilius Lovegood and Pandora Lovegood, and lives near the Weasley's house, in a black tower. She is also the cousin of Draco Malfoy through her father, who was disowned due to being a blood traitor. She was in her first year at Hogwarts School Of Witchcraft and Wizardry in Harry Potter's second year Harry Potter and the Chamber of Secrets and was in her fourth year when she first came into the series. In the movies, she was played by Evanna Lynch.
