M3GAN, a 4 Feet tall robot doll has been missing, she stumbled upon Hogwarts, a large Wizard school she decided it would be her best place to do some killing (only in a secret way / unseen) So she ended up breaking into hogwarts at night time at 12:00am and decided to go around and cause chaos whilst Students are asleep, and no student or teacher has ever Seen M3GAN, because she has blonde hair, blue eyes, she wears a beige color dress, with White and blue Stripey Sleeves, white leggings and black Mary Jane shoes, so that's a start because she's not in uniform, and secondly she's SEEN to be quite aggressive, since before she broke in hogwarts, she ripped some boy's ear off (strength of a gorilla) and caused An adult's leg to be seriously hurt to the point of limping so, M3GAN is one strong Person and surprisingly what's unknown to Students and teachers at Hogwarts, she can Fend off and fight the spells if they're casted at her, because M3GAN can control anything (or anyone if she chose to do that decision)
