While Harley Quinn doesn't die in The Suicide Squad, James Gunn promised fans that no character would be safe and that proved to be the case for many, as characters both old and new fell to their deaths. The most tragic of which is Rick Flag who is killed by Peacemaker for disobeying Amanda Waller's orders.
In what movie does Harley Quinn die?
