Astaroth was a demon who worked to condemn human' souls to Hell by turning them into witches
Astaroth was an extremely old and powerful demon.
She has the following demonic abilities:
- Possession - Astaroth secretly inhabited Tammi's body in order to trick Tammi's friends into becoming witches.
- Spell-casting - Astaroth had extraordinary knowledge of witchcraft, which she taught to her pupils in exchange for their souls. She also knew an exorcism which would send other demons back to Hell without affecting her, which she started to use on Ruby, she was also the one who taught Ruby all she knew about magic.
- Superhuman Strength - Astaroth was much stronger than humans as well as fellow black-eyed demons, as shown when she easily overpowered Ruby during their fight (although Ruby was a weak demon).
- Invulnerability- Astaroth could not be killed by old age, disease, or injuries dealt out by ordinary weapons. She also had some degree of immunity to iron, as she held a fireplace poker without any visible pain and used it to beat Ruby. However, she was killed when stabbed repeatedly using the Demon-killing knife, and was vulnerable to The Colt.
- Immortality - As a demon, Astaroth could potentially live forever, she was over seven hundred when she was killed.
- Telekinesis - Astaroth broke Renee's neck with a wave of her hand. She also pinned Sam and Dean to walls and held them incapacitated without effort while she concentrated on fighting Ruby, even beginning to psychically crush Sam to death at one point; however, she lost control of them when attacked by a spell that made her cough up pins. She also stopped a bullet from The Colt in mid-air, a feat no other demon has been shown capable of (although the majority of demons are often caught by surprise).
- Reality Warping - Astaroth granted the wishes of the coven once they sold her their souls; this included getting Elizabeth's husband a promotion as well as having her win a trip to Hawaii, and improving business for Renee's pottery business.
- Biokinesis - Astaroth killed Elizabeth by telekinetically stopping her heart. In demonology Astaroth (also Ashtaroth, Astarot, and Asteroth) is a Prince of Hell.
