Another deadly couple from Batman Animated Series: Two-Face and Poison Ivy. Unfortunately they didn't last, since Ivy's tried to kill Two-Face (the then Gotham's D.A. Harvey Dent).
Ironically it's pretty much like their friends: The Joker & Harley Quinn. Joker has been notoriously trying to kill Harley, but fail all the time. And sadly Harley always returns to her puddin'.
Anyway hope you guys like it!
