Varon-T disruptor
The Varon-T disruptor was a hand-held directed-energy weapon banned in the Federation due to its vicious nature: the disruptor literally tore the body apart at the molecular level from the inside out, resulting in a relatively slow and excruciating death by disintegration compared to more quick and painless means using phasers and other disruptors.

Only five were ever produced; four of them were owned by Zibalian trader Kivas Fajo, who slept with one of them under his pillow. Fajo used a Varon-T disruptor to kill Varria when she and Data attempted to escape his ship. When Fajo made it clear that he would continue to kill people, Data, realizing he had to be stopped and left with no other means of doing so, fired the weapon at him, but was transported to the  just as the weapon discharged, saving Fajo. () The fifth Varon-T disruptor was kept by the criminal Kelsey, who was killed when her scout ship exploded. ()
