Nova the Cat, Empress of the Sol Empire and Blaze the Cat's mother.

I came up with this character idea for my fan comic, Eon's World. I'd been thinking, if Blaze is the princess of the Sol Empire, who is the Emperor/Empress? Or is a matter of a kingdom being ruled by a Princess like in My Little Pony? As much as I like My Little Pony, if you're going to have a kingdom or an empire, I feel like it ought to be ruled by someone with a more senior title than "Princess", and that's where Empress Nova came from. Look out for her in Eon's World Vol. 1, season 4. This may not be the final look for her I settle on, but I think I did okay.
