        A sickly, bile yellow pool of liquid oozes towards you. As it approaches, the pool coalesces into the form of a beautiful young woman. As you look at her, you feel your body grow hot and burst into flame.

        Rarely encountered, the mitochondria eve is always the result of a medical or magical experiment gone wrong. These powerful and deadly organisms are the result of an endosymbiot known as a mitochondria gaining free will after their host is exposed to healing energies after the host is already dead. The most common way that this occurs is if a piece of the person's viscera, particularly the liver, are exposed to a regenerate spell or the like.

        In their natural forms, a Mitochondria Eve resembles a formless pool of sticky, yellow liquid, much like some variety of ooze. They can, however, take the form of their former host at will, though they lack garments, and their skin is perfectly smooth, lacking any hair or blemishes. While in their humanoid forms, Mitochondria Eve radiate a soft white glow, and speak with a haunting, echoing voice. All Mitochondria Eve are female.

        Mitochondria Eve retain the ability to speak any language the host knew before death.

Combat:

Mitochondria Eve consider themselves superior to all other life, and thus feel that physical combat is beneath them. If forced to, they are able to attack by slamming their opponent with a pseudopodium of their own substance, but prefer to use their immolating gaze and parasitic control powers to take control of their opponents or simply stun them with their supernatural beauty and move on.

        Alternate Form (Ex): At will, as a standard action, a Mitochondria Eve can assume her humanoid or liquid form. In their liquid form, she receives a +5 racial bonus to Hide checks and a +10 racial bonus to Move Silently checks and can use her climb movement rate, but cannot speak, or use her immolating gaze. While in humanoid form, she can speak, and use her gaze, but can't climb and has an overland movement of 30ft.

        Parasitic Control (Ex): A Mitochondria Eve can take control of any creature by infecting it with a piece of its substance. She usually accomplishes this by dropping a piece of her substance onto an unaware or sleeping victim. In such a case, the Mitochondria Eve must make a ranged touch attack to hit. A mitochondria eve can also infect a creature with a successful critical hit when she uses her slam attack.

        Any creature so infected must make a Will save (DC 18) or be completely taken over by the Mitochondria Eve, as if by a powerful Dominate Monster spell. This save is Charisma based. Once a victim has been infected the controlling Mitochondria Eve can use all of the victim's senses. Such victims have no ability to resist the commands of the Mitochondria Eve it is under the control of, and will follow even obviously suicidal commands. Such creatures are able to use the Mitochondria Eve's immolating gaze power. She can release an infected creature at any time.

        Immolating Gaze (Ex): Every round, as a standard action, a Mitochondria Eve can cause any living or once living corporeal creature within her line of sight to burst into flame by commanding the mitochondria within their cells to release their energy simultaneously. Such creatures must make a Fortitude save (DC 18) or burst into flame, taking 4d6 points of fire damage per round. Creatures that make their save take 2d6 points of damage. In either case, the victim continues to burn, taking the same dice worth of damage per round until the flames are extinguished. The flames can be extinguished by normal means. Constructs not made of flesh, elementals, outsiders, plants and incorporeal undead are immune to this attack.

        Supernatural Beauty (Ex): Because of the utter perfection of her humanoid form, and the force of her personality, a Mitochondria Eve receives a +6 circumstantial bonus to her charisma score for making any social interactions with members of any race that finds her attractive. Additionally, if she makes a successful bluff check, she can stun any creature that she gains her social interaction bonus from.

        Amorphous (Ex): In either form, Mitochondria Eve cannot be flanked, are immune to critical hits, and are not subject to death from massive damage.

        Memory Echoes (Ex): Mitochondria Eve retain the memories of their previous host, and can be distracted by a particularly moving event reminiscent of their past. If confronted by their host's former sweetheart or similarly emotional stimulus, the Mitochondria Eve must make a Will save (DC 21). If they fail, their previous host's personality temporarily takes over, effectively paralyzing the creature until the stimulus vanishes plus 1d6 rounds afterward. If she succeeds, she may only take partial actions on the next round, and must make another save the next round with a -2 cumulative circumstantial penalty. Once she fails a save, she cannot attempt another.

        This can only occur if the stimulus in question is not attempting to harm the Mitochondria Eve in any way, and is negated instantly if the Mitochondria Eve is attacked.
