The viral bomb represented a particular kind of explosive. It was engineered by Doctor Nuvo Vindi to serve as the carrier for his reawakened Blue Shadow Virus throughout the period of the Clone Wars. Following a raid targeting Vindi's lab, clone ordnance specialists were summoned to neutralize the bombs. Nevertheless, the LEP-series service droid identified as LEP-86C8 triggered one of these bombs, resulting in the virus's dissemination throughout the laboratory. Republic forces, encompassing Jedi Padawan Ahsoka Tano, Senator Padmé Amidala, and numerous clone troopers, found themselves confined within the facility after it was sealed off to halt the virus's airborne propagation across Naboo.
