Second Chance On Mad Love (Dc Universe Harley Quinn x male reader)

Slade Wilson, also known as Deathstroke, is a mercenary and assassin. Of former military status, subject of a failed medical experiment, he has since taken up work as a mercenary, armed with multiple weapons, and considered expert with edged weapons, firearms and explosives. Distinguishing characteristics include an impaired right eye, graying hair, and orange accented black body armor. His augmentations, coupled with his mastery of hand-to-hand combat make him a formidable opponent.

Wilson was an accomplished member of the special forces. This distinction earned him admittance into a covert program where he was subjected to extensive mental and physical augmentation. The procedures left him with increased mental function, as well as enhanced speed, strength, and stamina.
