Gideon wields an electrostaff, akin to those wielded by the MagnaGuard droids in Star Wars: Episode III - Revenge of the Sith (2005) and the various Star Wars projects involving Purge Troopers, which are elite stormtroopers in black lightsaber-resistant armor that support the Inquisitors and are trained to hunt and kill Jedi. They are best known as one of the main antagonists in Star Wars Jedi: Fallen Order (2019). Electrostaffs were designed for single combat against lightsaber-wielding opponents. Their blades generate a powerful electromagnetic field capable of blocking the plasma blade of a lightsaber, which is what allows Gideon to counter Bo-Katan's Darksaber.
