I had the idea for this character a while back, and I felt like sharing. This is meant to make him sound like a real phenomenon, but in the story I’m planning he’ll be a shadowy super assassin hunting down the main character.
The Manslayer, as he's come to be called, started as an internet rumor. It's unclear who or what he is. If any of the stories are true, he's possibly the most dangerous man on Earth. He could be a soldier following orders or the one calling the shots. He could be good or evil, one or many, or nothing at all. No one knows the Manslayer's true race, gender, or identity. Some claim he's not even human, that he's a time traveling android, or that he was bio-engineered by the government to carry out impossible missions. The most popular representation of the Manslayer is a super assassin serving the US government. They say the Manslayer shot Kennedy, the Manslayer killed Bin Laden, and the Manslayer played a part in every cover up, inside job, conspiracy, and every assassination.
Even though he's supposedly appeared throughout history, the Manslayer conspiracy has only existed since 2004 and very little is known. Most who try to find out more mysteriously disappear, or die in horrible accidents, which makes most wonder if there is any truth to the Manslayer conspiracy. If anyone ever finds proof of the Manslayer, it's likely they won't live to tell of it.
PS: If I had to give this character a theme song, this would be it:
