Gilderoy Lockhart

“I didn’t get rid of the Bandon Banshee by smiling at her!”

Fame-hungry, vain and utterly inept Defence Against the Dark Arts teacher. Lockhart achieved his fame through a combination of relentless self-promotion and stealing credit for the deeds of other (less photogenic) wizards by obliterating their memories. His days of (allegedly) travelling with trolls, holidaying with hags and gadding with ghouls come to an end when Lockhart accidentally wipes his own memories, and he ends up a long-term resident of St Mungo’s Hospital. But he can do joined-up writing now, you know!

Parvati & Padma Patil

“I still can’t work out how you two got the best-looking girls in the year.”

Parvati and Padma might be identical, but they’re quite different. Parvati enjoys dancing, juicy Hogwarts gossip, horoscopes and divination (particularly when taught by a certain blue-eyed centaur), and she can usually be found giggling with her best friend Lavender. Ravenclaw prefect Padma is more serious and studious – and yes, her nose is dead-centre.

Cho Chang

“If they think I’m not going to fight You-Know-Who after what happened to Cedric…”

Cho’s charmed life at Hogwarts as the popular, pretty Ravenclaw Seeker is blown apart by the death of her boyfriend. When Cedric is killed by Lord Voldemort, Cho is motivated to fight the Dark Side and defies her parents to join Dumbledore’s Army. She spends a lot of time trying to reconcile her “mixed-up, painful” feelings for Harry with her grief for Cedric.
