Original reference sheet for Ultimus the Dragon.

interesting, I have never seen art done of the red portion? What happened to that?
That'll be Id, the alter ego of Ultimus. While Ultimus is a very friendly dragon, Id has only 3 things in mind: death, murder, kill. In no particular order. Most people have issues drawing violence or bloody scenes or a dragon with crazed and murderous look so Id is not well drawn.
Id is featured in Order and Chaos https://www.weasyl.com/submission/111718/order-and-chaos
