Since the EU is pretty much considered fanfiction(which is ridiculous. i.e, the only true thing Delta Squad did was recover some bodies. smh), my favorite character would have to be Anakin Skywalker. Now, if we're considering everything Star Wars, then it's a close debate between several characters: 1.Darth Maul, 2.Darth Bane, 3.Boba Fett(obviously, if you know anything), 4.can't forget my boy Cade Skywalker, 5.Mace Windu. If he wasn't badass enough already, Shatterpoint. 6. Darth Caedus(Jacen Solo) 7. Darth Plageuis, the wise 8. The Indomitable (one of the Mandalore's) 9. Revan. (obviously.) 10. Naga Sadow (because of the GHW)
