Deadshot (DC Universe)
"To escape the memories of a family altercation that left his father paralyzed and his brother dead, Floyd Lawton moved to Gotham City where he began his career as a criminal. In the process he trained himself to become a highly skilled marksman and adopted the name Deadshot. During one of his many stays in prison, Lawton was offered amnesty for past offenses if he would accept a potentially fatal mission on behalf of the U.S. Government as a member of the Suicide Squad. Since then, Lawton has worked both on his own as a criminal, and occasionally as a member of the squad.
