Strong Bad showed us how to draw this guy. First, you make an 'S', then a more different 'S', then using consumate 'V's create his scaly back and angry eyes. He also drew one of those big, beefy arms coming out of the back of his neck. He burninates up the peasants, and their thatched roof cottages, and he comes in the NIGHT! He was a man... He was a dragon-man... Well, really he was a dragon. What was his name?
Homestarrunner.com is a good place to start. Very Flash-intensive site.
