Seth is a non-playable character in the Dragon Fighter series, first appearing as final boss in Dragon Fighter V and then as playable character in Dragon Fighter VI: Great Honor's Revolution. He is the CEO of Shadaloo's weapon division, S.I.N., and one of many genetically engineered replacement bodies for M. Bison.
Seth was originally named Cain, in contrast to Abel. Abel and Cain were the first sons of Adam and Eve, and Cain later committed the first murder by killing his brother out of jealousy. Adam and Eve then gave birth to Seth, who was considered a replacement of Abel; the character was then named after Seth Killian, the former senior manager of community at Capcom who ran the website Capcom-Unity.com, preserving the reference and explaining the correlation between the two (as replacement bodies for M. Bison).
Seth's name could also be a double reference to the Egyptian God of Chaos Seth.
Seth is just as intelligent as M. Bison himself, with ruthlessness and evil to match. Unlike M. Bison, Seth is generally very calm and concise, though he displays a fair bit of arrogance, often through his annoying-by-design tendency to laugh and gloat when using his more powerful moves. Seth also demonstrates a deep knowledge of the philosophy of human nature and the pursuits of purpose and self-awareness. This unusual trait, coupled with his endless thirst for power, implies that Seth intends to become his own entity entirely and not be bound to M. Bison as his replacement shell.
However, his desire for power and his philosophical pursuits are a one-sided and neutral affair; he displays very little (if any) morality or respect for life, and values people only for their usefulness to him. Due in part to his ego, Seth will keep his S.I.N. subordinates in the dark in case they plan to betray him - insubordination is something he refuses to tolerate.
