I'm on this page because I had the exact same question, and I now think that he's either in the Brotherhood Of Shadow or not in a specific faction at all, because on a lot of his wiki pages, it says he can change between his human and skull/hellish form at will, and that would support the idea of him being in the Brotherhood of Shadow. Also, in the Mortal Kombat X story mode, Scorpion is in his human form and has reformed the Shirai Ryu, that would support the idea of him not being in a certain faction, and go against the idea of him being in the Brotherhood Of Shadow. I hope this helped.
