Harry Potter
Harry Potter is the orphan wizard at the center of J.K. Rowling's seven books and the Warner Bros. films. Unlike his mentors, Harry rarely delivers polished wisdom; his best lines are quick, brave, and often sarcastic, aimed at people like Snape, Umbridge, and Voldemort. Every quote below is one Harry himself speaks, not Dumbledore or Hermione, with the book or film it is from.
“I don't go looking for trouble. Trouble usually finds me.”
“There's no need to call me 'sir,' Professor.”
“This is the best house I've ever been in.”
“I'll be in my room, making no noise and pretending I'm not there.”
“So according to you, Cedric Diggory dropped dead of his own accord.”
“It was murder! Voldemort killed him! You must know!”
“Interesting theory. Has anyone ever tried sticking a sword into Voldemort?”
“Fine, I'll stay here. Let me know if you ever defeat Voldemort, won't you?”
“I'd never have believed this. The man who taught me to fight Dementors - a coward.”
“My father died trying to protect my mother and me, and you reckon he'd tell you to abandon your kid to go on an adventure with us?”
“She's seeing someone. Jealous type. Big bloke. You wouldn't want to cross him.”
“Albus Severus, you were named for two headmasters of Hogwarts.”
“I'm not going to be murdered.”
“We're nearly there... don't worry...”
