Sektor

Sektor was once a loyal member of the ninja clan Lin Kuei. Once his clan started converting their ninja assassins into cyborgs, Sektor was the first who volunteered to undergo the procedure. He was a success and was send on a mission to eliminate Sub-Zero, a former Lin Kuei member, who went rogue.

Sektor attempted to finish his mission several times, but he never succeeded. He eventually had a program corruption and saw the Lin Kuei grandmaster as an inferior being, who wasn't worthy of being the leader of the Lin Kuei.

He killed the grandmaster, but wasn't able to attain the Dragon Medallion, the sign of leadership in the Lin Kuei. This was due to Sub-Zero's return. Sub-Zero defeated Sektor and took control of the Lin Kuei.

Sektor decides to flee to Japan and form his own clan, the Tekunin. Every member of his clan had to undergo the same procedure to become a cyborg.

Later Sektor captures and interrogates Taven. But before he could attain any information he needed Sonya Blade, alongside the Special Forces, attacked his warship. The attack led to Taven's escape.

Sektor fights with Taven, but looses and flees. What happened to him after those events is unknown.
