- "I assure you, sir, that this bomb only works on droids."
- ―Sionver Boll
The electro-proton bomb was a type of bomb designed to emit an electromagnetic field that could take out droids. It was designed by Sionver Boll for use by the Galactic Republic, but the bomb's use had unintended consequences. While it was successful at taking out droids in service of the Separatist Alliance on Malastare, it also upset the planet's eco-system, awakening an ancient and powerful creature known as the Zillo Beast.
