His victims' lightsabers
The brilliant, cybernetic mastermind behind the successes of the droid army of the Separatists, General Grievous led the series of lightning strikes that opened a corridor for the invasion of Coruscant itself. Beyond his status as a military genius, he was also a cunning and devoted warrior driven equally by a love of combat and the rage he felt at his mutilation and imprisonment within a lifesaving cyborg frame. Though he first appeared on the Republic HoloNet as a wartime rumor, he quickly grew to the status of legend as the Republic met defeat after defeat at his hands. Trained in lightsaber combat by Count Dooku, his mythical status was cemented after single-handedly defeating no less than five Jedi on Hypori. He met a warrior's death at the hands of Obi-Wan Kenobi after a brutal, bare-knuckle fight.
