Electro Voldrums are a type of Voldrum encountered only once, in the upper levels of the Celestial Archives. Like all Voldrums, they are spherical ground-based combat robots equipped with two large guns on each side of an omnidirectional wheel. The Electro Voldrum is yellow in color with a bright purple wheel, and as the name implies fires two projectiles resembling charged affinity Volt Driver shots, although these projectiles are incapable of homing and do not explode on impact. Like Kanden and all other users of electrical weaponry, the Electro Voldrum is immune to all variants of its own weapons system, but extremely vulnerable to the Battlehammer and other heavy-duty attacks. All other weapons damage it normally.
