Shadaloo is a fictional crime organization which is run by Bison. Its insignia is a winged skull with a lightning bolt—forming an "S" for Shadaloo—etched onto its forehead. The symbol can be seen on Bison''s cap, as well as in numerous cut scenes. The Four Main members of Shadaloo include Balrog, Vega, Sagat, and Bison himself. Balrog and Vega were recruited by Bison with the promise of massive wealth, whereas Sagat was motivated to join by the prospect of revenge for his defeat at the hands of Ryu in the first Street Fighter tournament. In Street Fighter II, Bison ostensibly hosts the game''s fighting tournament to seek out new talent for Shadaloo.
