Neville Longbottom is a fictional character in J.K. Rowling's Harry Potter book series. He is escribed as a round-faced Gryffindor student in Harry's year. Throughout the series, he is often portrayed as a bumbling and disorganised character, and a rather mediocre student (though he is highly gifted at Herbology). However, the character's personality appears to undergo a transition after he joins Dumbledore's Army in Harry Potter and the Order of the Phoenix. The encouragement he receives gives him confidence in his magical abilities, turning him into a more competent wizard. As the series progresses, he becomes close friends with Harry, Ron, Hermione, Ginny, and Luna.
