Sektor is a member of the Lin Kuei clan who volunteered to undergo cybernetic automation, transforming into a soulless killer. In Mortal Kombat 3 and Ultimate Mortal Kombat 3, he is programmed to hunt down his former ally, the rogue ninja Sub-Zero. Sektor's gameplay signature includes using heat-seeking missiles, a teleport uppercut, and a flamethrower.
During the development of
Mortal Kombat 3 (1995), co-creators Ed Boon and John Tobias conceived the character under the development codename "Ketchup," contrasting with his yellow counterpart Cyrax, who was codenamed "Mustard." Actor Sal Divita portrayed the character using digitized sprites, wearing a red-accented cybernetic suit inspired by armor designs from science fiction films.
Within the narrative of
Mortal Kombat 3 and
Ultimate Mortal Kombat 3 (1996), this character represents the successful culmination of the Lin Kuei's cyber-conversion initiative. Unlike his cybernetic counterparts who struggled against their programming, this unit embraced his transformation, exhibiting a complete lack of remorse or desire to reclaim his human soul. This ideological divide established a long-standing rivalry within the
Mortal Kombat franchise lore.
The character's inclusion in
Ultimate Mortal Kombat 3 solidified his status as a mainstay of the mid-1990s fighting game era. His fatalities, which include a compactor mechanism that crushes opponents, showcased the franchise's signature dark humor and technological themes. This distinct visual identity and narrative role laid the groundwork for his subsequent appearances and evolution across the broader franchise.
