That's a lot of pokedex entries... I've got to admit though Quetzalcoatl + Koala = [Quetzal]Koalius is pretty clever. (At least I assume that's what they were going for based on the Aztec-looking accessories and stonework on the throne.)
There's very little beyond the color and possible ears (what I initially thought were legs) to link it to "the blue thing" here though. It really isn't drawn with any real sort of distinctive details to let us draw a strong conclusion.
Maybe that's the artist as he represents himself as a blue mouse
@retros64 Did you draw this art and the other pieces you uploaded? Because if so, you've got a good handle of things so far!
What is Myoria though? I could barely find anything on this 'Monochrome World' fan game, with only this one video, which has one of the characters in it, but makes no mention of this Myoria.
Gorgon subspecies exist. Near-east and Indian subcontinent Gorgon have Cobras for their hair, Amazonian Gorgon have Boas (exceptional individuals have Anacondas), North American Gorgons tend to have Rattlesnakes (or Moccasins)... Good thing I just bought a drawing tablet.
