Name: Real: Tom M. Riddle, Made up names: Voldemort, Lord Voldemort, my Lord, He-Who-Most-Not-Be-Named, and You-Know-Who.
Movie: All the Harry Potter movies except PoA
Henchmen: All Death Eaters(followers), Dementors, Giants, Werewolves, and other dark creatures
Sex: Male
Powers: He is a very powerful wizard. He can do some spells that others cannot and he can also do Occulmency, which is a special ability that not all witches and wizards have and it takes a ton of practice and time to be able to do. You are able in a way to read a person's mind or posse a person. Something that Voldemort does to Harry in OotP. Also, you are able to send emotions to another person, emotions that you are feeling.
Arch Enemy: Harry Potter, for there had been a prophecy made that had stated that the Dark Lord would mark a child born on the seventh month and who's parents fought against him three times and survived as his equal. So, as long as one lives the other cannot, making it so that in the end, either Harry will die or Lord Voldemort will.
Shamefull Secret: He is a half-blood. His mother had been a witch and his father a muggle(non-magic folk). His father had left his mother when he had found out that she was a witch, then Voldemort's mother had died giving birth to him, leaving him alone and sending him off to an orphanage, but stayed alive just long enough to name him after his muggle father. So, through his pain and anger Tom Riddle tried a way to rid the world of muggles, muggle borns, half-bloods, and muggle lovers.
He started this by finding out that he was the heir of Slytherin and in his sixth year at Hogwarts going and opening the Chamber of Secrets letting out a monster that was to kill or petrified any muggle born or half-blood in the school. He had killed a muggle born girl. Then he went and killed his father and his step mother. Later he came back to full power in Harry's fourth year using an old ancient spell to give him back his body. He used the bones of his father, the flesh of his servant Wormtail, and Harry Potter's blood. Yet, he himself was a half-blood, a lot like Hitler in a way.
Only Weakness: Albus Dumbledore, the only man that Lord Voldemort ever feared. For Dumbledore is the most powerful wizard in the world and had once been one of his professors. Dumbledore had always been onto Voldemort, even when he was in school and just starting to turn evil.
Most Common Actor to Play role: Unknown by me.
