In the books and films, Ron and
She's seen as a bit absent-minded, is easily distracted, and is extremely eccentric in both her disposition and general outward appearance. But that's what makes her a perfect Ravenclaw. She loves learning, but unlike many of her housemates (or Hermione, for that matter), she can never know enough.
Luna Lovegood may be odd, but she's a Ravenclaw through and through. Luna Lovegood is Harry Potter's quirky but kind friend whom others had nicknamed "Loony Lovegood" due to her belief in mythical creatures and oddball phrases.
She is perceptive
Ravenclaws are perceptive, and Luna noticed all kinds of things others didn't during her time at Hogwarts. There was that time she explained Ron in one sentence: 'He says very funny things sometimes, doesn't he?
Why was Luna Lovegood sorted into Ravenclaw? Because honestly, if you think about it, she was the one of the smartest at Hogwarts. Nobody else just thought like she did could, she was unique in that manner.
And this is why Hermione does not fit into Ravenclaw, since she lacks their creativity of thought. When you also add in her fearlessness and her strong convictions about right and wrong, which are inherently Gryffindor traits, then there was even less of a chance she'd end up wearing blue and bronze.
Moaning Myrtle
Born in the late 1920s to Muggle parents, Myrtle Warren started her Hogwarts life in the early 1940s, where she was sorted into Ravenclaw. She had no friends, and was bullied relentlessly because of her glasses and acne. But she would soon have all of eternity to get her own back.
He rejected his family's pure-blood elitism and reverence for the Dark Arts. At Hogwarts, rather than be sorted into Slytherin like the rest of his family, Sirius was placed in Gryffindor.
Mad-Eye Moody is a Hufflepuff.
J.K. Rowling did not explicitly write the character of Luna Lovegood as a person with Asperger's. But because she is a good writer, she created a character with a distinct personality that is also familiar in many ways.
Luna is asked, "Which came first, the phoenix or the flame?" to which Luna says "I think the answer is that a circle has no beginning." When Amycus Carrow seeks entrance, he is asked, "Where do Vanished objects go?" Amycus is unable to answer, but eventually Professor McGonagall answers with "Into non-being, which is ...
It's not in-canon, but I'm speculating that they originally kept Luna in the basement for ready access to keep Xenophilius under control. After Xenophilius was sent to Azkaban I think they discovered that Luna was helpful in keeping Ollivander alive.
Her name matches her personality
Luna was continually teased at Hogwarts for being eccentric, for being a bit of a free agent and for following the beat of her own drum, so much so that she was perceived as being not all there.
Hermione points out that Padma and Parvati Patil are twins, yet while Parvati ended up in Gryffindor, Padma is a Ravenclaw.
Albus Dumbledore: Gryffindor
Some people show traits from multiple houses, and although Dumbledore is definitely one of those, his passion and courage make him a clear Gryffindor.
Even J.K. Rowling says that Hufflepuff is her favorite House. It's produced the fewest Dark wizards of all four Houses. Hufflepuffs are down-to-earth. Literally, their House colors represent wheat and dirt, symbolizing their humility (rather than the precious metal secondary colors of the other Houses).
The Heir of Hufflepuff was a person foretold by the Seer Harmonthrep (Ajrand) to bring great glory and honor to the House of Hufflepuff, considered boring and lackluster by most.
Severus Snape, Horace Slughorn, Andromeda Tonks, Narcissa Malfoy and Regulus Black were all Slytherin heroes in their own way, if you think about it. And Merlin – as in, yes, King Arthur's advisor and the most famous wizard in history – was a Slytherin.
Sorted into Gryffindor house, Remus Lupin was swiftly befriended by two cheerful, confident and rebellious boys, James Potter and Sirius Black. They were attracted by Remus's quiet sense of humour and a kindness that they valued, even if they did not always possess it themselves.
