Is Koros the earliest of Yasuhiko's evil women? She certainly seems to be the model for Gundam's Kycilia, Ideon's Harulu, and Zeta's Haman Karn, doubtless among others I'm forgetting.
Of course, Koros is from Daitarn 3, which is a far more comedic series than the others. While she's given a certain gravitas, she also engages in physical humor of a type which would seem... unbecoming of her followers.
