From Another World

What if characters from one world met characters from another world? Who knows what happens, but it's always fun to imagine things like that. Here, I decided to have one of those scenarios on paper. The story here is as follows:

A typical day in Satan City takes a sudden twist as a couple of bank robberies on opposite sides of town catch our heroes by surprise. Eventually we find Sayiaman bound to a tree by Poison Ivy, looking to make his first kiss(?) his last, while Harley Quinn makes faces to everyone. On the other side of town, Sayiagirl has her hands full with Killer Frost, who has frozen both of her hands together, and Giganta looking to take her out from behind. How will they get out of this mess?
