Thanks all, for the Sarah Jane votes. This time I think we'll go with Doctor Who monsters. We'll leave out the Cybermen & Daleks and any other robots, just in case there's any debate on whether they're monsters per se. Any actual monster that's appeared in classic or nu Doctor Who goes. Other usual rules apply. 150x150 pixels / 140KB max.
Now we're getting somewhere! I think I'll leave this go a couple more days. We need more than 5 entries.
