Emperor Kyle Katarn

This is likely one of the coolest part of the game Dark Forces 2: Jedi Knight.  Depending on how you act earlier in the game, you either finish the game as a Light Jedi, or u turn to the Dark Side and become the new Emperor.

Parts:
Kyle Katarn [head]; EU Luke [whole]

Recipe:
A really easy custom.  I just did a head-swap, then painted him all black.  His shirt, the cuffs on his knees above his boots, and half of his arm were painted charcoal afterwards.  I did that to keep him dark, but give him some color other then black.
