Seth (Street Fighter)

Seth is the main villain of Street Fighter IV. He is the leader of the Shadaloo weapons division S.I.N.

Story
Seth is the 15th of 26 enhanced beings that use data collected from the world warriors to create a deadly style of mixed martial arts. Seth claims to be superior as a result of his humanity while the others are merely puppets. His storyline indicates that he plans to control the remnants of Shadaloo through S.I.N after Bison's apparent death at the hands of Akuma in Street Fighter II. He also attempts to manipulate Juri Han, a woman who possesses a bionic eye he created. She confronts him and unexpectedly offers to work for him, to which he agrees. He hosts a World Warrior tournament in hopes of luring Ryu to complete his BLECE project, but is dismayed at reports that Bison has once again returned from death. Bison finally encounters Seth and defeats him in combat, and afterwards tells him that in fact everything that has happened has gone according to Bison's plan. After Bison leaves, Juri tells Seth that she intentionally pitted the two against each other, but is disappointed that Seth was not more of a challenge for Bison.[2] Afterwards, Ryu would encounter another Seth and defeat him and destroy the BLECE machine. Bison commands the remaining copies of Seth and they wreak havoc on the fighters in and around the S.I.N. compound, as many of the characters' endings depict them defeating a version of Seth.
