Fei Long and Dan will be added as bonus characters to the console versions of Street Fighter IV.
The new boss of the game will be Seth "the Puppet Master".
Seth is the CEO of Shadowloo's weapons division S.I.N.
Seth has reconstructed his body (with cyborg parts?) to max out his fighting potentials.
Updates:
Seth takes data from many different styles of martial arts and makes it his own, utilizing his own physical abilities to maximize and perfect those moves.
