Penelope Platypus

A member of the Substitute Freedom Fighters from Downunda, Penelope was one of several Freedom Fighter recruits chosen by Sally for a special mission meant to determine their potential. The mission resulted in the uncovering of Robotnik Prime's Auto-Automatons, a scheme that the Substitute Freedom Fighters - aided by Geoffrey St. John - were able to thwart. Penelope and the others would later come to the aid of Sally and her more experienced squad on several occasions, including a bizarre conflict involving a video-game link between Mobius and Earth and a period of time in which Sonic was bereft of his speed. Penelope would later be elected to serve on the Council of Acorn.
