The Scorpenek annihilator droid was a massive droid constructed by the Colicoid Creation Nest.
HistoryEditThe Confederacy used these droids later in the Clone Wars. They were first used when the Republic launched a attack on Colla IV. There one was able to destroy 4 platoons leaving no survivors except one. The Scorpenek droids won more victories on worlds such as Formos and Palanhi.  Rumors that they could annihlate dozen of republic tanks struck fear into the republic's citizen's hearts. During the outer rim sieges, Republic commander had to send large numbers of troopers to take one out.
Unfortunately, these did not have any major effect on the war due to their enormous cost. There were only at 100 available for combat. When the Clone Wars ended, they were deactivate by Lord Sidious's new apprentice, Darth Vader.
