Pharmakon

Pharmakon is a droid sent by Esmeraude to fill a vulnerable spot with dark energy. Her arms are made of needles and can inject people to make them sick. She appeared in Episode 31 of Sailor Moon R.

Esmeraude placed a Dark Wedge in a hospital, one of the vulnerable spots of Tokyo, and summoned Pharmakon to fill the area with dark energy by making everyone sick with the flu except Minako and Chibiusa. When the two girls went to get medicine, they discovered what Esmeraude and Pharmakon were up to, and fought them. Pharmakon pinned Sailor Venus to a wall with needles and went after Chibiusa, but Tuxedo Mask shattered one of her needles, and then the other Sailor Senshi, having recovered from their flu, arrived to fight Injector. Esmeraude ran off while Sailor Moon destroyed Pharmakon.
