Ok, not technically a character, but come on! Who wouldnt want a Bessie toy to play with? Make it compatible with the various action figures and youd have something really fun!

Admittedly, Im pushing it a bit with this one. Again, this is a character from a really not great episode, but the character herself was fantastic! Give her the Nemesis arrow, and possibly a chessboard, and we could have a lovely little toy. Heck, better still, do a "Silver Nemesis" boxed set with her, Richard, Nemesis and Ace carrying a slingshot.
