Grazza

Darth Nihilus looks the coolest though, even if he is quite weak when you fight him on the ravager.

About the only hard thing on Korriban is in Ludo Kressh's tomb/vision chamber at the back of the cave, and then only if you're playing the Exile as LS - if LS, your force points don't regenerate. Still, its not too hard anyway, and all that happens if you die is you get a few DSP - In here, death isn't permanent.

R4-P17 is Obi-Wan's astromech droid that he used in Attack of the Clones. He was the one the buzz droids destroyed in the Battle above Coruscant at the start of Revenge of the Sith. He then got a new R4 unit for the rest of the movie.

HK-47 is the greatest - He is a good fighter AND provides the comic relief. He better be in KotOR III (Supposing there will be one). Apparently, he's even in the latest upgrade to Star Wars Galaxies.
