Thanks again for the win in the last contest. This week's contest is for avatar's featuring a character, thing, place, villain or alien race that has only appeared once in Doctor Who, so far. For example, that could be a guest star which has appeared in only one of the new series episodes or in only one of the classic serials (the guest star can have appeared in more than one ep of the serial), etc. I'll post the voting thread on Friday night (GMT). Have Fun!
