SV-3 Eradicator was an experimental battle droid deployed during the Battle of the Red Reaper. This prototype droid was tasked with guarding the Red Reaper's bridge from being seized, and its armaments were enhanced using six enigmatic Sith power sources. These power sources, when correctly configured, amplified the droid's offensive power to the point where a single attack could be lethal. Despite this enhanced lethality, the droid met its end in the conflict at the Battle of the Red Reaper.
