HK-47

HK-47 is an assassin droid built by Rarth Devan. He joins him on the Ebon Hawk and becomes part of the Freakshow, and later helps Guy from KOTOR 2 as well. He is good at fighting and often defends little T3-M4, in return for T3-M4 providing him with constant repairs.

You would expect this to make them good buddies, but its anything but. Any hint of conversation and they immidietly argue. Good thing they both like to stick to the task at hand, unlike some whingers. In fact, HK-47 seemed to just sit around and watch his master torture innocent people. Well, he is an assassin droid.

What's remarkable is that HK-47, being very strong and sturdy coupled with continuous repair from T3-M4, actually managed to survive all the wars he has been in and lived up to and beyond the Galactic Civil War. What an awesome guy!
