Deadpool Has His Own Harley Quinn (But with a WAY Darker Ending)
Deadpool once briefly had his own version of DC’s Harley Quinn, but rather than become a fan-favorite hero, the character had a much more tragic ending. In a story arc that featured the fourth-wall breaking, antic Merc With a Mouth institutionalized, he was treated by Dr. Ella Whitby, a blond psychologist whose interest in his criminal mind becomes a romantic obsession.
