The electroguillotine functioned as an execution device, severing the heads of those sentenced to death. An electrostaff served as the activation mechanism for this device. Constructed from laser energy, the guillotine was a formidable instrument. Towards the conclusion of the Onderonian Civil War, an electroguillotine was scheduled to be used for the execution of Ramsis Dendup. This execution was disrupted by the Onderon rebels, who almost succeeded in freeing the former king. The rebels found themselves surrounded by B2-series super battle droids, leading Sanjay Rash to declare their impending deaths via the electroguillotine. Nevertheless, Akenathen Tandin and the Royal Onderon Militia intervened, preventing Rash from carrying out the executions and facilitating the escape of Dendup with the rebels to the Onderon rebel safe house.
The Electroguillotine made its initial appearance in the Star Wars: The Clone Wars animated television series, specifically in "The Soft War," the fourth episode of its fifth season, which debuted on October 20, 2012. Its identification was first made public within the episode guide accompanying "The Soft War."
