Lee Harvey Oswald

Lee Harvey Oswald was, according to four government investigations, the assassin of President of the United States John F. Kennedy, who was fatally shot in Dallas, Texas on November 22, 1963.

When working at "Billy Land" he had a vision of the Bat asking him if he wanted to be this Country's Next Hero. The Bat ordered him to protect Kevin for the sake of mankind. Later in JFK Assassination he actually wasn't the murderer. At the time JFK was shot he was at the library building with Jackie, but in the end he accepted to become scapegoat instead.
