But Roddenberry loved the idea of aliens with irresistible sexual allure, as we saw with Orions, Elasians, and Deltans (and Taureans in "The Lorelei Signal," though Roddenberry probably had less involvement there). Of course, it was a common enough fictional trope in the era, the idea of female villains weaponizing their sexuality to bring men under their power. That was Poison Ivy's original shtick in 1960s Batman comics, controlling men with hypnotic cosmetics, and we saw it in the Batman TV show with Marcia, Queen of Diamonds and the Siren (and arguably Black Widow, though since Tallulah Bankhead was decades past her seductive-vamp days, they made it technological mind control with no sexuality involved). And it's a much older trope than that; misogynistic fear of female sexuality as a dangerous power over men was a motivator behind the Salem witch trials, and you can track it back much further to the Lorelei and Sirens of mythology. Given all that, though, it's a bit surprising that Roddenberry considered employing the trope with a male character as well.
