His thunder sword is such a rip off man... I bet the animators were sitting around one day trying to think of ideas for the filler arc and the new star wars dvd ad came on or something.... the rest was all ripped.... honestly they didn't even both to give it different sounds to a lightsaber to make it more original...

The only thing they didn't rip off from the lightsaber was the whole thing made it cool... its ability to cut through pretty much anything...
