It's Constant! AKA the only dragon I have. There are all of two images of her that come remotely close to the dragon "breathe fire/smoke" trope, and this is one of them!
Drawn by Sisuitl, who's disappeared from online, I like the real gremlin energy brought here. While she likes to present herself as classy and suave, Constant's absolutely also a greedy little gremlin at times.
Still, she always has hair worth looking at.
