Is it bad I got a power rangers vibe after seeing those images?
Go, go, evil Sith Lords! NA NA NA NAAAAAA!
And personally, I'd like to see Jedis wielding uncommon sabers.
I remember there being a Jedi named Corran Horn in the Expanded Universe who had a silver-bladed saber that could extend to three meters in length whenever he wanted it to. Pretty cool, and a lot more interesting than the same old blue or green sabers with a fixed length that we've seen repeatedly in the movies. As it is, the most unique saber in the movies is Mace Windu's and only because Samuel L. Jackson specifically requested that his saber be a different color from the rest. And Yoda's saber...short and green, like he is. I wonder how many hours George Lucas spent coming up with that one.
I would've made Yoda's saber completely white, as a representation of the light side, and the Emperor's saber black, like that darksaber I showed you, as a representation of the dark side. Besides the symbolism, the darksaber just looks really freakin' cool.
