"So Is J'Onn the Sheriff?" from Justice League Europe #27 (DC, 1991) by Keith Giffen, Gerard Jones, Bart Sears and Randy Elliott
Though JLE was the more serious of the two JLI books, there was still room for comedy. Power Girl's mangy cat, for example, got itself a couple of solo issues and they are among the most memorable of the run. But the book also gave us the lethal Exterminators and Metamorpho's family trouble. After Breakdowns, things went south QUICK. The JLE moved to a haunted castle, Power Girl got a truly horrifying costume, oh and there was a storyline where one of the male members possessed her body and try to sleep with the female Dr. Light before walking on all fours like an animal. That's when I decided I'd had enough.
