Her most Imperial Majesty, Mother of the Fatherland, Overlord of Vulcan, Dominus of Qo'noS, Regina Andor, Philippa Georgiou Augustus Iaponius Centarius is a female Terran who was the Emperor of the Terran Empire during the mid-23rd century. Ruthless and xenophobic, she was incredibly successful at conquering and oppressing other species.
Michael Burnham brought her from the Mirror Universe to the regular Star Trek one to save her life, because Michael felt guilty for her own Capt. Georgiou's death. Somehow she was shocked to learn the evil Mirror Universe version of her commander was ... y'know ... evil.
She has sex with a pair of Orions, male and female. The male says she's so good (at sex) that they shouldn't charge her. The female says "But we do." And then Georgiou holds them at gunpoint until they give her the information she wants.
Like we said, evil.
In her universe, apparently everyone is Pansexual, but she's the only one who's made it clear so far.
