Professor Neville Longbottom is one of the main protagonists of the Harry Potter franchise. He appears as a major protagonist in The Philosopher's Stone, The Chamber of Secrets, The Prisoner of Azkaban, The Order of the Phoenix, The Half-Blood Prince, and The Deathly Hallows. He is one of Harry’s core closest friends.
At first shy, but Neville learns to stand up to his enemies and his friends. He is the arch-enemy of Bellatrix Lestrange, the woman who tortured his parents to insanity. Harry helps him to be the best WIZARD he can be. In the seventh and final book, Neville gains confidence to stand up to Lord Voldemort. He was able to let Harry take the final blow to Voldemort because Neville decapitated the last Horcrux, Nagini with the Sword of Gryffindor.
Seventeen years into the future, Neville married fellow Dumbledore's Army member Hannah Abbott and became the professor of Herbology at Hogwarts.
In the film series, he was portrayed by Matthew Lewis.
