Right, apologies if this is in the wrong section, please move it if it is.
A usual, my tiny speck of a butterfly mind has been ruminating on a problem and I would like advice.
A while ago, I picked up a Scooby Doo themed boardgame (essentially snakes and ladders with a cool spinny bit in the middle) and had plans to replace the cardboard counters with Hasslefree's not-Scooby Gang adventurers.
Now that HF are about to release "Hamlet", a fine looking doggie, I am much closer to achieving this.
However...
I would also like to replace the counters for the bad guys with appropriate models. The counters in the game all depict the Evil Robot:

And I was wondering if you fine fellows had any ideas for suitable proxies.
I can't find anything myself, so was thinking that I could swap them out for ghosts, werewolves etc, and would appreciate any info on suitable ones that I could get that would be:
a. Available singly
b. Not horribly expensive
c. Require no or minimal conversion
All suggestions gratefully recieved.
