"So You Need a Crew?

As the leader of the Legion of Doom, Lex Luther made a statement on TV after Doctor Psycho very publicly referred to Wonder Woman as the c-word, stating that the Legion did not condone his statement and kicking him out.


Luthor welcomed Harley as a contender to become the new member of the L.O.D. although it was actually a ploy to get Harley's best friend Poison Ivy, who had rejected their invitations 148 times, to join.
