Bertram Aubrey attended Hogwarts School of Witchcraft and Wizardry during the 1970s, where he became an unwilling participant in one of the most notorious pranks in the school’s recent history. His time at the castle would be forever marked by an encounter with James Potter and Sirius Black that demonstrated the casual cruelty often disguised as schoolboy mischief.
The incident that thrust Aubrey into Hogwarts folklore occurred when Potter and Black, likely during their later years at school, decided to test their magical abilities on a fellow student. They enlarged his head to twice its normal size using magic, creating a spectacle that drew attention throughout the castle. The prank left him unable to fit through doorways and required intervention to reverse the effects.
This particular episode reveals the darker side of the Marauders’ reputation for mischief-making, showing how their pranks sometimes crossed the line from harmless fun into genuine torment. Aubrey’s experience serves as a reminder that not all magical practical jokes were as lighthearted as they might initially appear, and that the victims of such behaviour often faced real consequences.
Though his Hogwarts house remains unknown and few other details of his school career have been recorded, Aubrey’s unfortunate encounter with two of the wizarding world’s most famous pranksters ensures his place in the school’s unofficial history. His story provides context for understanding the complex legacy of James Potter’s school days and the sometimes problematic nature of teenage wizarding behaviour.
