SQ change shape (any Large or smaller humanoid or antrophomorphic outsider; shapechange), mother of fiends
Environment any (Hell)
Mother Of Fiends (Su) A kaikesi can conceive a fiendish offspring with most mortal or immortal beings, either in the real world or in her midscape shared with the other parent. While pregnant, a kaikesi can cast create greater demiplane that will last for 1 day, with flowing time that will make its internal time equal to the remaining duration of pregnancy, emerging from within with a newly born offspring, usually a half-fiend or an occasional demigod, but sometimes merely a tiefling or a new asura.
Veil Of Motherhood (Su) A kaikesi gains +4 deflection bonus to her AC all the time. Additionally, any creature that sired an offspring with the particular kaikesi suffers –4 penalty to attack rolls, caster level checks against that kaikesi, and can't use any mythic abilities against kaikesi (including spending mythic power), the kaikesi gains +4 bonus to her saving throws against effects produced by that creature and ignores the creature's DR and SR as long as their shared progeny lives.
Kaikesi are powerful asuras that seduce gods, fiends, celestials, and occasional mortal hero to sire champions that will bring ruin to the divine powers and their creations. While other asuras often court them, kaikesi usually reject them, in favor of gods, demigods, and celestials. They rarely pick fiends for their consorts, choosing only the most powerful and the most closely related to the hated gods—for they seek to turn the power of deities and their own creations against them. They seem to have a degree of fondness for rakshasa accepting them more often than other fiends, though.
