24. Darth Malak (Star Wars: Knights Of The Old Republic)
https://www.youtube.com/watch?v=aUHDL-2C0yM Considering the huge jerk that your former apprentice had been to you for the entirety of Knights of the Old Republic, it's fair to say that putting the boots to Malak was worth all the hassle you had to go through in order to get there. As the final battle with him progresses, it evolves from a simple one-on-one lightsaber fight into something more dramatic as the Dark Lord begins to siphon life energy from Jedi that he has trapped in a state between life and death. This raises the stakes, creating an entirely new battlefield that becomes even more compelling. Dividing your attention between the trapped Jedi aboard the Star Forge and fending off Malak's vicious attacks is tremendous fun, as it is a very clear test of your ability to multi-task. It's a fantastic test of skill, one which you can continuously come back to again and again to see how far you can push yourself.
