Joker & Harley Quinn, The Final Fight

This story is partly about Joker and Harley Quinn's relationship and how I would like it to be. It talks about my idea of Harley Quinn's origin. However, the story is not only about Joker and Harley Quinn, it also has characters such as Batman, Alfred, Gordon, etc. Please remember, the characters and parts of the storyline are owned by DC.

Joker finally escaped Arkham Asylum with the help of his new love Ms. Harley Quinn. His only goal in life is to make Batman kill him to prove that people are as bad as they seem, but once he meets Harley, he decides he isn't ready to die just yet. Instead the two come up with a new plan to trick Batman. Will their plan be successful?

PS: Violence! Some would say gore, please be aware!!!
