Harry Potter and The Neglected Hero (Rewrite)

Harry is three years older in 1981. Voldemort attempts to strike him down with the killing curse, only to lose his body and his magic to burn a scar in Ian, Harry's little Brother. With Ian mistaken as the BWL, Harry is ignored and makes his own way in life, with the support of his friends and little sister. (Grey Harry!) (Older Harry!) (Ravenclaw Harry!) (Slightly Younger Cedric!)
