I guess

Idius Halfhwit is one of the smartest students in school, just behind Hermione and Luna. In fact he is brilliant. Now in his fourth year of Hogwarts School of Witchcraft and Wizardry. Idius finds himself at his peak potential, a five star man, finally able to combine his intelligence, courage, ambition, and... what was that final one.. the ability to get bullied? But being around in the age of the Golden Trio makes it tough to be recognized. This year though, may be different, probability may be on his side.
