“Assigned to psychoanalyze the clown prince of crime, Dr. Harleen Quinzel thought she could cure The Joker. … Instead she fell madly in love with him. To prove her feelings were certifiable, Dr. Quinzel helped him escape from the Arkham Asylum. Driven over the edge with obsession, she became Harley Quinn, The Joker’s sidekick and girlfriend.” Sony Online Entertainment released this brief introduction of Harley Quinn alongside a few screenshots of this mischievous jokester in action. Come 11 January, DC Universe Online will be available for all of us, and those who decide to wreak havoc on the side of the villains will be able to play side-by-side Harley.
