'Scorpion' [Srqt] is also the name of the quasi-mythical second King of Egypt, who preceeded king Narmer (the king who united Upper and Lower Egypt in around 3150 B.C). The only clear evidence of Scorpion's existence is provided by the so-called 'Scorpion Macehead', which is housed in the Ashmolean Museum in Oxford. All the books I have which mention King Scorpion compensate for Egyptologists' profound lack of knowledge by filling up space describing the appearance of this artefact. In fact, some scholars remain unsure that Scorpion even existed, suggesting that 'Srqt' was merely an official title of another king. If he existed at all, Scorpion's tomb is almost certainly located somewhere at Abydos, where the tombs of other First (and some Zeroth) dynasty kings have been discovered. It is possible that the four-chambered tomb in Abydos designated B50 was his final resting place, but conclusion remains impossible in the absence of firm evidence.
Oh, and have a look at Serqet if you want a Scorption-Goddess:
