Seth

Seth was one of special bodies created to be the new body for M.Bison. For some reason Seth became self-aware and was more than just a puppet.

Seth wanted to take control of Shadaloo through his organization known as S.I.N. He started the BLECE project, which couldn't be complete without Ryu. To lure Ryu to him, Seth decides to sponsor another World Warriors tournament.

He also gets Juri Han to work for him. During the tournament it is revealed that Bison has returned. Seth battled with Bison and lost. It was revealed, that Juri manipulated the tournament so, that Bison and Seth would fight.

After the tournament Seth's BLECE machine was destroyed by Ryu.
