|~ Dean during the Battle of Hogwarts.|
Dean Thomas is one of the many characters from the Harry Potter series. He is a Hogwarts and Gryffindor student, and member of Dumbledore's Army.
Dean Thomas attended Hogwarts and was sorted into Gryffindor. He was best friends with Seamus Finnigan, and good friends of Harry Potter, Ron Weasley, Hermione Granger, Neville Longbottom, and Ginevra Weasley. He joined Dumbledore's Army, led by Harry Potter. He fought and survived in the battle of Hogwarts, and witnessed the death of Lord Voldermort. His life after the war is unknown.
He was portrayed by Alfred Enoch, who also portrayed Wes Gibbins on How To Get Away With Murder.
Dean was open-minded. When Dolores Umbridge referred to Remus Lupin as a "dangerous half-breed", he jumped to his former teacher's defence. On two occasions, he told her and another teacher, Professor Snape, that Lupin was the best Defence Against the Dark Arts teacher that his class group ever had.
Dean was generally an easy-going and good-natured person, able to get along well with many people. He never displayed any anger towards Harry Potter during their sixth year, especially when his ex-girlfriend Ginny Weasley started dating Harry shortly after breaking up with her, because he was aware of Ginny's childhood crush on the Boy Who Lived since she came to Hogwarts a year after the two boys started. He also easily established a friendship with Luna Lovegood, whom many would consider bizarre.
He was brave and loyal. He was eager to participate in the defence of his school against Death Eaters, despite not even having a wand, and never lost his faith in Harry Potter, believing him when he claimed that Lord Voldemort had returned. He also had faith that Harry would eventually defeat the Dark Lord.
Dean was apparently willing to violate school rules, if doing so would help a friend. In his third year, when Harry was not allowed to go to Hogsmeade because his uncle had not signed his permission slip, Dean offered to forge the signature (unfortunately Harry could not accept, as he had already mentioned to Professor McGonagall that his form was not signed).
Dean was a skilled artist and also enjoyed reading the comic book Loony Nonby v.s. Cornish Pixie, showing an interest in art.
- Rowling included information on Dean's background in an early draft of Harry Potter and the Chamber of Secrets, but ultimately cut it out, as she felt it was an "unnecessary digression." She stated that she had to a certain extent traded Dean's "voyage of discovery" for Neville Longbottom's because the latter character's discoveries about his past were more relevant to the main story.
- His name was "Gary" in early drafts of the first book.
