Frederick Charles Krueger is the product of the violent rape of the nun Amanda Krueger by one hundred maniacs (a.k.a. "The bastard son of a hundred maniacs). Called Freddy, he was constantly ridiculed for his infamous and brutal conception. It was then he started murdering small animals, and as he grew into adulthood, he turned his masochistic behavior on himself. After suffering abuse from his stepfather for many years, he brutally murdered him with a razor. It was after child services took his daughter away that Krueger became a child killer earning the name "The Springwood Slasher". After he was captured for his string of grizzly murders, he was unexpectedly freed on a technicality. The enraged parents of Springwood, OH then took the law into their own hands. They followed Krueger to a building where he took his victims and ignited it with gasoline into a raging inferno. However, no one expected the end result of this act.
Freddy's soul was so corrupt that it was decided he could be of use to dream demons imprisoned in hell. When he was promised eternal life in the world of dreams, Freddy could hardly refuse. Ever since that night, Krueger has taken his revenge on the parents of Springwood by stalking their children through their dreams. Each time he is able to twist what would seem to be a normal dream into his own brutal imagination's delight of terror. Some children have escaped thinking they have defeated him, only to have him rise again sometime later.
http://www.imdb.com/character/ch0002143/bioRick Grimes was formerly a police officer in the small, peaceful town of Cynthiana, Kentucky. After waking up from a coma, he has become a reluctant figurehead of a group fighting to survive a world where the dead no longer stay dead.
Rick is very much a driven and optimistic individual. Coupled with his law enforcement background, he is quickly seen as a prominent leader within the group of survivors he first encounters. Initially Rick is highly idealistic and mentally strong. this allows others around him feel comforted and safe in his presence. As the months pass and the increasing number of fatalities within his group, we begin to see his character slowly breakdown mentally and emotionally. Despite this apparent deterioration he is still regarded as a rock amongst the other survivors and his son.
