Originally just a member of the French Resistance during World War II, Marie fought the Nazis starting with Star-Spangled War Stories #84 (August, 1959) by Kanigher and artist Jerry Grandenetti. Mlle. Marie's appearances lasted through Star-Spangled War Stories #91 (wherein her feature was taken over by the dinosaurs of the War that Time Forgot), but Marie soldiered on, meeting Sgt. Rock, Johnny Cloud, the members of the Haunted Tank, the Hellcats and the Unknown Soldier (all World War II heroes, co-created by Kanigher).
Rose and Thorn
Kanigher wrote most of the back ups (with Cary Bates writing a few), and other artists on the series included Gray Morrow, Dick Giordano, Rich Buckler and Don Heck by the back-ups end in Superman's Girlfriend Lois Lane #130. Rose and Thorn came back in Superman #336 (June, 1979, by Len Wein and Curt Swan), and in two issues of Brave and the Bold (#188 and #189, written by Kanigher, and art by Jim Aparo) with Batman.
With DC Special Series #6 (November, 1977), Poison Ivy joined forces with Grodd, Sinestro, Bizarro and Kanigher created Wonder Woman foe, the Angle Man to fight the JLA with the Secret Society of Super-Villains! Later still, she joined forces with all DC villains in the Crisis on Infinite Earths!
In the Harley Quinn series, you can see more of the pin-up girl in the art of Terry and Rachel Dodson...and more so in her later appearances as well, like in Gotham City Sirens, and she was even part of the Birds of Prey with Black Canary to start of the New 52!
