Hugo Mattingley was a Ravenclaw student at Hogwarts School of Witchcraft and Wizardry in the 1990s. He was usually seen spending time in the Transfiguration Courtyard during the 1996–1997 school year. He was a fan of Gilderoy Lockhart. Unlike most people who think that Slughorn is a stakeholder, Trevor thinks that he is a good teacher. One day he was duelling and beat him. The blow was so powerful that he needed two days recovering in the Hospital Wing. Would like Hagrid's work. He wanted a new broom.
