The electric shields1, 2, also called power shields3, 4, 5, 6, 7, were a pair of weapons carried by Tahnok-Kal that controlled the forces of electricity.4, 5, 6, 7 They could be used both offensively and defensively: they could hurl bolts of electricity at opponents3, 4, 5, 6, 7, and they could create a protective force field of electrical energy4, 5, 6, 7 that even a Toa Nuva could not overcome.3 They could contain and release hundreds of thousands of volts at once.1, 2 The electric shields were detachable weapons, but they needed to be connected to Tahnok-Kal to work.8, 9, 10
Since the Bahrag created Tahnok-Kal by mutating an ordinary Tahnok11, 12, 13, 14, the electric shields may have originally been fire shields. They may have survived Tahnok-Kal's defeat when it succumbed to its own electric power, since Tahnok-Kal merely became trapped by its own electricity15, 16 and had its moving parts fuse together17. It is unclear what became of the electric shields after this.
