Sionver Boll/Legends

Dr. Sionver Boll was a scientist who served the Galactic Republic during the Clone Wars. She designed the electro-proton bomb, an explosive device that created a massive electromagnetic pulse. The first use of the bomb, on Malastare, opened a sink hole at the blast site, resulting in the awakening of a Zillo Beast. However, once Anakin revealed that not even his lightsaber could cut through the beast's armor, she and Chancellor Palpatine both expressed interest in studying the beast for possible reproduction of its scales as indestructable armor.
