Scariest monster ever

By far the scariest monsters are the ones that are rarely seen. When one is locked behind bars the imagination can take the character to a whole new level of frightening. Hannibal Lecter is in my opinion the scariest monster of all time. No one ever sees the atrocities that he commits so my imagination took it to a whole new level. He is a serial killer who is known to maim and dismember his victims. With this much violence in ones mind, no one truly knows what he is capable of and this makes him even more lethal. While a six headed monster that can breathe fire is pretty ridiculous and scary, many people are able to just shrug this one off because it simply cannot be real. A man who terrorizes people is more realistic and the realism of Hannibal makes him the scariest monster of all time.
