[L'Empereur]

Gordan Freeman from the Half-Life series(probably INTP though)
The Glorious Strategist from Jade Empire (either that or ENTJ)
Modrin Solus from Mass Effect 2
Lightning from Final Fantasy XIII ??

 

[L'Empereur]

Revan sounds right. Starkiller might be as well. He's definitely introverted, detached from his Fi and is coldly efficient. Star Wars has a thing for INTJ sith lords, what with the emperor and Darth Vader.

Galen Marek "Starkiller" or Bendak Starkiller?
