Star Wars: 10 Expanded Universe Characters We Hope To Never See Again
8. Rosh Penin Jedi Knight: Jedi Academy

Only appearing in the Jedi Knight: Jedi Academy game, Rosh is pretty much the worst aspects of Anakin Skywalker taken up to a whole new level. Hes whiney, arrogant, and constantly complains about how his master is holding him back and stopping him from become too powerful.
As well as that, hes just a bit of an arse. Hes hugely competitive which leads to him setting a Lightsaber-wielding droid on fellow Padawan Jaden Korr so that the droid will slow Korr down, allowing Rosh to finish a training course first despite there being no competitive element to completing the course. And, of course, he falls to the Dark Side and starts spouting all the dull clichés about the attraction of power. Killing him is a joy. Its just a shame that you can only do it with a Lightsaber when rocket launchers, disintegration rifles, and trip mines are a part of your arsenal.
