Answer Harry Potter and the Sorcerer’s Stone
In Harry Potter and the Sorcerer’s Stone, Harry and his friends embark on a perilous journey to the dungeons where they come face to face with none other than Lord Voldemort himself. Although his physical form was compromised, his strength was still enough to kill the young students.
