This is a remix of Gamera by mrksuckerberg which gives it horns (Bull Skull by McMarx) and hair (Dumpster Fire - Everything is Fine by Kokanee483) to make it look like a realistic version of Bowser, King of the Koopas from the Mario series.
Version 2 also replaces the legs (Godzilla by Anycubic_Community), tail, and shell (Dragon Turtle by mz4250).
