An Elder Thing from Lovecraft's At the Mountains of Madness depicted in flying/swimming mode. The star-shape surrounding it is made of marine and prehistoric creatures including anomalocaris, trilobites, comb jellies, jellyfish, ediacarans and more.
The stars are right for those born under the sign of Scorpio!
It was a terrible, indescribable thing vaster than any subway train — a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and un-forming as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter.
— H. P. Lovecraft, "At the Mountains of Madness"
