This lovely creature was in the same story/RPG i used to do with a friend back when i was a writer, her name is Erica-La once again before much of any history of knuckles' spiecies in the comics were revealed she was supposedly the original creator of the Chaos emeralds, however, this is not her true form, this is how she appears to the Echidna's. no one truely knows what her true form is.....only what they seeker of her sees, be she Echidna, dingo, hedgehog etc......her background is shrouded in mystery that i have yet to unveil....
