Voldemort

This villain has become one of the most renown bad guys in fantasy literature history. J.K. Rowling has even commented that her objective was to create the ultimate villain. Indeed she has, for this character is the most benevolent and unforgiving figures I have ever encountered in my years of reading. His story is not much different from the story of Satan in John Milton’s Paradise Lost. This character in my opinion is the ultimate definition of evil in human form.
Voldemort was born named Tom Riddle. He was raised in an orphanage never knowing his parents, since his mother had died and his father had abandoned him. Tom was a trouble-maker for all of his childhood. He discovered his ability to talk to snakes and make people bend to his will. Albus Dumbledore, a teacher at Hogwarts school of Witchcraft and Wizardry brought Tom to the school to be trained in the magical way. Tom made a close group of friends who would eventually become his followers. He left school and began his reign of terror on the magical community, killing people at his will.
As his reign grew stronger, Tom took the name Voldemort and set out to become the leader of the wizardry world. He soon heard of a prophecy in which he would see his downfall from the child of two people who had defied him. Voldemort took this prophecy to mean Lily and James Potter. He went to their cottage and killed them both. However he was unable to kill the baby boy. The killing curse rebounded and disfigured Voldemort. He fled and hid in a forest for many years. Voldemort’s followers were still willing to bring him back.
By using Harry Potter’s blood, the hand of Voldemort’s servant, and a bone from Tom Riddle Sr., Voldemort was able to form a body in which he appeared as a snake-like figure with red eyes. His return was short and Harry Potter killed him. From this point on, Voldemort was stuck in a permanent limbo in which he could never return to life.
