Polly Piston is an adventuring gearhead from a parallel steampunk world. She is plucky, resourceful, and whip-smart, yet you can't help but feel the desire to protect her. She has an unassuming tomboy-ish sexiness like Kaylee from Firefly or Gadget from Rescue Rangers. She uses Cockney rhyming slang and British phrasing to play up her AU London origins, but we'd ideally like to hear versions of her lines both with a working class English accent and without (as if she's an expat who has picked up the language but not the accent).
